September 26, 2006 What? Update: Well, the bandwidth for this post is becoming too expensive, so I've gotta pull the plug on my files. Jimmy has posted a little Flash app with similar tones. So maybe you've heard about this story, maybe not. Here's the 10-second version: Most humans are born with the ability to hear frequencies from about 20 Hz (low) up to 20,000 Hz (high) but that range shrinks as we get older. A guy in England figured that meant kids can hear things adults can't - specifically, very high frequencies. He created a device that pulses an annoying tone at about 15,000 Hz with the idea that when the device is used, it will repel kids while being unnoticed by adult. Perfect for solving that youth-loitering problem you've been having in front of your shop. Okay, so that was, like, 15 seconds. I owe you five. Steve posted links to two samples of the device. He could only hear the sound in one of the samples. I too could only hear the sound in one of the files. Sample 1 Sample 2 Being the skeptic that I am, I smelled a rat. Did the sound even exist in the other one? Time to open my spectral analyzer to find out. Damn, there it is. That big peak just above 15,000 Hz. I lowered the pitch just a tad, and started to hear it. Sample 1, slowed down I then wondered where my frequency threshold was, so I made a few sample tones. 10,000 Hz 11,000 Hz 12,000 Hz 13,000 Hz 14,000 Hz 15,000 Hz 16,000 Hz 17,000 Hz 18,000 Hz 19,000 Hz 20,000 Hz 21,000 Hz 22,000 Hz 23,000 Hz 24,000 Hz 25,000 Hz Mine's at about 15,000 Hz. Comments mike i love steves website and well now i dontthanks to that horrible prank he pulled onus im not sure ill ever hear again Horace This is great to check the ages of people I work with. Good site. Sean Interesting, but you didn't filter out the harmonics.... Alex This is great, im 31 and i could hear it with no problem i would'nt use this to get rid of people i would use this as a prank i agree with all the kids saying this is discriminatio, but if you know were i could download it i would appriciate ty jake I can hear 16,000 quite clearly and I'm a 36 year old male. just for your records there. Jay I'm a month shy of 49 and can her 17,000 very clearly - 'course my wife complains that the smallest sound wakes me up. Amazing I got any sleep as a teenager. yuri Im 20 and i can barely hear the 17000 But I kill ears with loud music all the time so maybe thats why... thanks ochenk that was cool Thom Not sure if this counts, when I listen to the 22,000 I instantly get a ringing in my ears that stops the moment the file ends. I am 20 myself, and have always considered myself extra-sensitive. Ashley I'm 22 and I had no problem hearing them. Although it seems as if my ears wont be the same after this. Heidi I just turned 35 and can hear all of them except for 22,000 hz. Jacqueline I'm 21 and I cold hear the 19,000 just fine, but not 20,000. Mark Hey, I'm 21 and I can JUST BARELY hear the sound @19000. 17000 sounds EXACTLY like what an old monitor my mom had would do. It bothered the hell out of me, and she couldn't hear it. I think next time I go home I'm going to have her listen to this and see where her's cuts out. Pip I can't "hear" anything above 16000, but the files make me physically uncomfortable until about 21000. I'm 27. Nancy I'm 31, and I can barely hear the 17000, though both 18 and 19 give me a headache and make me want to do that cartoon-character-one-eye-bigger-than-the-other -head-tilt face of pain. 16 and below are very clear and very uncomfortable. There's a security gate on the second level of a local library that is emitting a sound somewhere in this range - none of the other 12 or so people I was with heard it, but man, I couldn't get within 15 feet of the thing! Poom I'm older than dirt but I can still clearly hear the 10,000 Hz sound. Stef Anyone know what decible these are played at? That's a major factor when testing hearing loss... some people can hear the frequency at greater decibles, but not at what is considered "normal" hearing. Ochen K. "Anyone know what decible these are played at?" Hi Stef, The tones are generated at -6db, but of course, the volume at which you play the files will dertermine the final db. amanda I can hear all of them...am I weird? Stian I'm 28 and have had some degree of tinnitus for the last 4-5 years. 17000 is my limit. Shows that this is higly individual and also depends on your speakers. I used headphones. Jimmy As another 49 year old, I find it bloody depressing that Jay could hear up to 17,000 Hz. I'm down to 13K myself... :-( What a drag it is getting old. -Right, Mick? Mick? Can you hear me? Panda I hear all of them except for 19000Hz. In fact 20000 & 21000Hz come in loud and strong, but not 19000Hz. I'm 28. Leif I'm 31 and could hear the 16,000 Hz. I've got really crummy speakers though. I thought I could hear the 17,000 Hz faintly but then I kept hearing the ringing after the file stopped playing. What's that about? morbot hmmm, i am 33 and i could hear the tone in the original, and i tend to drop out at 19000hz range, but i have always had decent hearing, and yeah, the monitor sound, always drives me crazy. donna I am a 39 (and forever holding) female and I could hear the tones in all the ranges. Maybe that's why I can always hear my kids muttering under their breath behind my back. under 20 unknown I am under 20, by a few years i might add, and i can hear all of them ,including 22000hz, as clearly as the others. i tested with my speakers and headphone, and i could hear them just as clearing through both. colin i know i can pretty well up to at least 20KHz, but i think my sound card won't do more than about 15KHz. stupid laptop. Joy I can hear them all on my real computer with good speakers, and I can hear up to 20 on my laptop. Hearing loss runs in my family, i think I bit the lucky one. Plus, I'm only 19, give it time. gisele I tried these last night on my computer at home, and then this morning on my computer at work. Last night my boyfriend (23) and I (22) could hear up to 19,000 Hz, and nothing after. This morning I can hear every single one of the levels listed. Even the ones higher than we could hear last night. interestingly my boss (40's) couldn't hear 16,000-18,000 but could hear the ones after and before... Pea-Brain I'm 16 and i could hear both sound samples. #1 was annoying but I couldn't imagine it getting me out of a store. #2 however was horrible. It was a steady ear piercing (with a ice pick) murderous tone. I have heard a sound similar to that in math class from an unknown source. Now I know why the teacher doesn't seem to notice it. I have a headache now. I could hear 10,000 and up but it dropped off at 20,000. I could faintly hear 22,000 if I turned the speakers up all the way. Claire I'm 18 and I could just barely hear the 21,000. crazy. neighborcat I'm 36 and I can hear every file! They make my mouse go "Click!" OK, actually, I can't detect tones above 19K, which is surprising since I was a drummer in a very loud band and have a fondness for loud motorcycles and jet engines. Copious amounts of beer must be theraputic! James Weird, I can hear all of them to some degree. 13,000 would make me kill myself if I couldn't get away from it. From 15 to 19K I can just barely hear it, then from 20k on up it's very very LOUD! Morgan Hmmm i'm 23 and I could only hear up to 12,000. This makes me nervous Noam 23 years old, I can hear 17,000 and below very clearly. 18,000 and above are complete silence except for some clicks which I assume are part of the wav, or my soundcard, not actually the sound file. Mike #18 Wow I never really thought my car audio love has done much harm, I figured it didn't help my ears, but I'm surprized I can only hear 15K max, 20/21 come in faintly, but it maybe my speakers/sound card or something...I've tried the tones with good quality headphones and a decent speaker setup. 15k comes in pretty well, and whatnot below it. Carl I can only hear up to 18k, but at 19 and 20k, it makes my head hurt, even if I can't hear it. 21 and 22 just buzz. I don't think my sound setup likes them. My volume's at a normal level. I'm 19 and have very good hearing. Darren 35 yrs old. I can hear clearly up to 15khz and can hear 16khz with headphones. Can't hear anything beyond that. Thanks for reminding me how old I'm getting! Lex I am 23. I could hear all of them up to 21khz and somewhere around 17 it began to make me feel like I was going to have an anxiety attack. Maybe it is a good way to keep some people out Rita I'm two months shy of 26 years old, and could hear every single frequency as clear as a bell. I don't know whether to feel proud, or like some sort of freak. Kattan Just turned 27 and I can hear the 18000Hz. 19-20 I couldn't hear but I got a slight headache after listening twice. Guess my hearing is good enough. Andrew I'm 19 and I could just barely hear 15,000. Probably a bad sign seeing as I am going into sound recording. Dave I could here up to 20k at with my speakers at the level I normally use them(the dial's at about 20% max). For 21k and 22k I had to turn the dial to 75% max before I could here them. I dont know decibal math, so what db level would 75% put -6 db at? Umpqua Age: 34 I heard them all clear as a bell. Jessica I heard them all. I also teach Kindergarten, is it possible that since kids tend to have better hearing than adults can we," catch" their good hearing..hmmmmm??? Mark Age: 22 Heard all of the clearly Jess Age 29. I can hear up to 19,000. bboy Well, I could hear tones on all these files. However... I hate to be a bubble-burster, but this test is flawed, for several reasons: 1.) Many speakers and headphones are physically incapable of creating very high frequency sounds. This applies especially to low-end equipment. Some are only specified to play sounds into the 15kHz range. This limitations is called dynamic response. Others may have a 'band-pass' filter to prevent some frequencies from playing. 2.)There are tones playing in these files other than those expected. These tones are so-called "lower-harmonic" tones. These tones occur at integer divisions of a listed tone. For example, in the 22kHz file, there will be audible tones at 11000Hz (22000/2), 7333Hz (22000/3), 5500Hz (22000/4), etc. 3.) Due to the nature of digital sound formats, the ability of a wav (and especially compressed formats like mp3) to faithfully reproduce high frequency tones is limited. I wont go into detail, but this file is a 44kHz file, wich means 44000 'samples' per second, or only two samples per half-cycle of the sound wave, at 22kHz. That is the bare minimum, even in ideal circumstances. Suffice to say that only proper equipment can reliably tell you whether your ears can really detect tones at a particular frequency. This calls for a professional exam with an "audiometer" or at least the use of audiometer software with some high-quality computer equipment... Not all audiometer tests test for 'extinction frequency' anyway (I think that's what it's called...). Anyway, I'm not an expert, so I may be wrong about some of the details, but I just thought I'd let everyone know. =) bboy Oh, and BTW, I'm 23. I could hear them all, but I have a waveform-generating software, and I could distinguish the tone up to about 18000Hz before the sound was drowned out by the 'lower-harmonics.' Breezie I am 12, almost 13, and i could hear all of them through 21000. 21000 i could barely hear. My speakers suck too. But HOLY CRAP MY EARS WONT STOP RINGING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! katie very cool. i can hear up to 20 ok, gets lost after that. btw this is driving my cats nuts. Karl Way wicked test! I'm 16 and i can hear them all, there might be something to it after all. Greg I'm 28 and have been suffering from tinnitus for a few years due to too much rock 'n' roll. I can hear up to 19,000, but with very much pain. Matt Ok, I may have the strangest tale yet. I came here when the story was first published on The Sneeze, and I heard them all. Then I came back when I was showing it to someone else, and I could only hear the first two! Now today I can hear them all again. I am 27, and I used the same headphones at the same volume level each time. Thinking about what changed, the only think I can come up with is that I was sick the time I couldn't hear them. Not congested, mind you, just generally achy with a sore throat. The effect was dramatic, so much so that I thought the sound files had changed. Make of this what you will. Jess I'm 25, and I'm good up to 20,000. At that point, I blessedly hear nothing. Joyce I'm 50 and i could hear up to 15000, after that nothing until 20000 and up felt pain in my ears. Franky I am 16 yrs old and can hear up to 19000, but everything after that i couldn't hear, but felt vibrations in chest and head. (My mom says i would be able to hear so much more if i hadn't ruined my ears by playing load music ROFL) Bear I just turned 30 and I can hear 15,000 but not 16,000 at a reasonable volume, listening on headphones. Heidi I am 17 and I can hear all of them. Is that normal? melons all i hear in sample 1 is kids laffin n 2 taps...and i can only hear up to 19,000 hz...wut does dat mean? oh yea n im 17. Anders I'm 16 and I could hear up to 20,000Hz. I could also hear 21,000 and 22,000, but the pitches seemed significatantly lower. I maybe I am hearing the sound a few octaves lower than what it actually is because the sound is resonating my lower hearing? or am i b.s.in gall of this? Daniel Of course it could also be that not many people can hear about 19KHz because not many speakers can produce audio above that, too. Look at the rating of your speakers -- chances are they, too, produce sounds from 20Hz to 20KHz. FTR, I could hear both initial samples and noise also up to 19KHz (my speakers peak at 19.5KHz) but I could hear faint noise on the rest. Ken Lets see I could faintly hear the 17000 MHZ example and the 16,000 Mhz example basically shot me out of my chair. Now that one is annoying. As for the Mosquito example I could faintly hear the tone so I'm figuring it's somewhere between 16 and 17,000 MHZ. Katie i can hear to about 21 then it just stops Susan So... the idea is that kids who've destroyed their hearing with heavy metal concerts, ATVs, dirt bikes and iPods are welcome in the stores, but kids who spend most of their time in the library can just stay there? Sounds like a good idea to me. JJ 32 yr old mother here, i lost it after 16000, my 17 yr old step son came to check on what was making him sick all the way in the kitchen, lmao, and he loses it at 18000. The look on his face was pricless, I'm gonna mark this site and use it as punishment! Listen to me or I shall maketh thee vomit!!!! Mo I could hear all of them. I'm 24 and of the female persuasion. The first five made me feel like aliens were reprogramming my brain. Is that what a dog whistle feels like. Gah! Yincira I'm 19, I could hear the first two samples, and from the second one up to 18000. markster At forty years' old and with a ranch standard Dell laptop soundcard and sony earphones I couldn't hear anything above 13. What I could hear though was most unpleasant. With no. 2 of the 2 original sound samples, I couldn't hear anything but I did get a needleprick headache every time I played it, and I found that most disconcerting as I read similar comments afterwards which showed that it was clearly more than just a placebo. It's all disconcerting and almost scary; I expect this kind of stuff is probably required listened at Guantanamo... Rhiannon I'm 24 and I can hear the 17,000... but the higher ones do cause an uncomfortable buzzing sensation. I can't hear them, but there is a definite feeling of discomfort when they're playing. It feels like being in a room with a TV or monitor that's been left on with no sound or picture. Joanne well, dayum, I'm 53 and as much as I hate to admit it... my 16 yo daughter is right... she hears better than I do. I didn't hear anything but background noise on sample one, nothing on sample two and only up to 12,000 - NOTHING after that. Dayum. Daughter hears through 19,000. Apparently all those years as a librarian shushing people didn't do a thing for my hearing. ;))) Gideon I could hear through 19,000 and I am 25 Jono 18 years old and couldnt hear a thing past 15k. Coro I'm 26 and could hear 19k, nothing after. But my cat was sitting next to me and she told me she could hear all of them. Actually, I've been in places where I'll be like "Ah, ow!! What the hell is that sound?!!!" And other people don't hear it...but you know what? I haven't watched TV in like six or seven years and every time someone turns on a TV, even if I'm all the way across the house, I come in and beg them to turn it off because of the hi-pitched noise. Mary I can hear 10-15 but not 16. I'm 38. At 10 it made me wince. tone I'm 37. I can hear all the 10k to 22k samples clear as day but can't hear the ringtone in the original sample 1. Odd. I hear up to 15kHz (not 16kHz). I'm 22, I guess my ears aren't the best IRock I can hear it all the way to 2x10^20 Hz!!!! txexspeedy 39; anything at 15,000 up I hear as a little pop and very tiny crackle. Below very loud and clear. Chris I could hear them all just fine except 16000Hz. Wonder why that is? Trillian Interesting. I'm 35 and maxed at 16,000/17,000. Like others have mentioned, the higher frequencies made me wince, even though I couldn't really hear them. I guess that explains why I can always tell when someone has left the tv tuner on in the basement, even when it's just a blue screen with no sound. Chris Crap btw Im 32. :) Stephanie Too many concerts by the speakers without earplugs. My hearing is shot to hell. At 14000 can't hear a damn thing. It's truly tough to get old. lawman311 im a 23 yr old male, i can hear up to 19,000 Alex mp3 quality probably doesn't reproduce these high frequences right, although reading the comments it seems that it must work at least partly. Tim I can hear all of them clear as day anyone know where i can test 23khz? Mike I'm 31 and hear the 22,000 just fine. Years ago, my brother was in middle school and kept getting headaches. Turns out they had some sort of device to drive away (bugs?), at something like 25khz or 28khz. My dad, then in his 40s, could hear it. Glen I'm 38; I couldn't hear anything above 16k. Mike I'm 20 and I can hear the 22,000 perfectly fine. Brian 38 Strange. I can hear all of them except the 15K through 19K ones. Christian Hey, 30 here and I can hear all of them except the 22,000...Anyone know what the frequency of a TV picture tube is off hand? I can tell if televisions are on in other parts of the house even when the sound is turned off and was just curious. Thanks Geoff At the level where I normally keep my speakers, I cut off after 17k. Turning the volume up just a little bit made me able to hear up through 22k. Not sure the final dB level, so I have no idea what to conclude. I'd like to point out, though, that the sound drove my cat insane. At all the levels. Geoff er, forgot to add that I'm 22. Matt older than old dirt-- I can hear 14000, but nothing after that. JSZ0 25/M, all the way up to 22K loud and clear. Any chance of posting higher samples? (assuming our speakers can actually replicate frequencies that high) Alice ouch ouch ouch ouch ouch!!!!!! my ears stopped hurting..but it made my headache much worse...thank you O_o haha...only got up to 20000...cuz now my grandma's cooking so i can't hear anything on my laptop -_-'' gonna have to continue after she's done...and then make my migraine worse ^-^ JJF I'm 48, male, and hear the 10K and 11K and nothing beyond that. Maybe I listened to too much loud r&r in my teens and 20s. Greg I'm 27 and could hear up to 19. harrycary I'm 41 and can hear up to 20,000Hz. Not bad after all the concerts I've been to in the past 20 years. Tom 23, could hear everything perfectly, even at low volumes. Preferably at low volumes. >. Peppelin I'm a 25/M and also can hear all the way up the 22k. :) c00L I am 24 and at first run I could only hear about 17000hz. I always had good hearing so I thought to give my ears a good scrub down with q-tips. On the next try I got up to 22khz. So some of you who are getting bad results try cleaning your ears, like your momma told ya. ed i was in the navy from 38-51 as a fighter pilot. i'm 89 and i can hear everyone one of thoses channels clear as day. and i can still do code at 55 words a min. RMX Note that on some speakers/headphones you'll hear the octave below the tone being played; and on others the frequency cutoff of the speaker will stop the sound for you. On good speakers I can hear the 17000 one; and 18000 - 19000 feel more like an annoying ear-ringing headache sensation than a sound to me; and on my crappy PC speakers I can hear all of them, though almost certainly not playing the intended sound (20000 sounds like lower pitched buzzing than 17000). My dad (68 yrs old) can barely hear the 10000 one; and can't hear the beep on his microwave oven or crickets outside - though he still enjoys music and can hear speach and TV reasonably well. He thinks he suffered hearing loss when he was exposed to lots of loud noises in the military long ago; but never really got it checked out. I can hear through 17000 clearly. The only other one I can hear is 21000, but the pitch I hear is more like 12000 only quieter. I wonder if this is some sort of resonance. Kelly That sound made my skin crawl. Ben Christian, if I remember correctly the frequency of a tv tube is in the 17000 range. Personally, I can hear every single sound, but dang those are annoying. Of course, I am in the intended age range for the teenage repellers. HortonM I'm 61 (he says unabashedly) and I can hear up to 13K and then nothing. My 9 year old grandaughter can hear the 22khz cycle easily and is amazed that I can't. Such is youth. Rob I'm 19 and the last one i can hear is 18,000 Josh I am 16 I can here all of your samples but not the actual recording of the device. Are these correct? I hate the thought of these, I hope their business drops off. Jerry I am 29 and I think something is not right with the sound files or my ears. I can hear all frequencies except 16,000hz, 20,000hz and 21,000hz. What give? Tucker I can only hear up to 12k.. major tinnitus.. 30 yrs old Eric I'm 28 and could only hear up to 13,000. Am I screwed? I have no idea what the deal is.... *nervous* andy i could hear 17000 but 18000 was silent :( im 17. Jery I meant I cannot hear 16k, 21k and 22k. I can hear 17khz to 20khz frequencies. nate I'm 20. I can hear all of them, but above 20kHz they're not as loud. Still enough to make my head hurt. rob I'm 54 and I hear 15k clearly, 16k fairly well, and 17k, 18k as thin 'pressure' rather than tone, nothing much above that. btw I'm a sound engineer and consultant in acoustics, with live concert experience going back to 1973- I studied noise exposure and acoustics early on, and I've taken good care of my hearing. Ray 37 and I can hear all of them in both ears with no issue, other than the fact the right ear tends to feel a ticklely sensation when listening to the tones above above 19,000. I am curious how far I could hear above 19,000, you should post another 5-10 samples higher than 22,000. Perhaps I am part dog or something... ;-) greg 36 here, and the last one i could hear was 15k Ryan I'm a kid and i could hear them all easily, i would like to hear ever higher ones to see how far my range goes, if anyone knows a link to some email me, awesomeness9110@yahoo.com, thnx :-) David Doran I am 16 and I can hear up to 22,000. I went back through some of them and some like 15,000 are quite discomforting. Ray that was a typo I meant how much higher above 22,000, I could hear. (not 19,000. as I have already established I can hear up to 22,000.) So none of those tricky teenagers will be fooling me with their 19,000MHZ mosquito cell phone ring tones! Hey you answer your cell phone will you! And STAY OFF MY GRASS PUNK! ;-) Nicholas Ok, I'm confused. I'm 25 years old, but I have deafness in both ears (not 100%), and I have tinnitis. I could hear every sample very well. I don't see how you couldn't hear the high end ones... they were quite annoying. What does this mean? I can't normally hear people when they speak, but I can hear these sounds extremely well. Gabe 30 here. Can here up to 20, at 21 I can feel my ear hairs wiggle but can't detect noise. So much for loosing your hearing in the military. Ray that was a typo I meant how much higher above 22,000, I could hear. (not 19,000. as I have already established I can hear up to 22,000.) So none of those tricky teenagers will be fooling me with their 19,000MHZ mosquito cell phone ring tones! Hey you answer your cell phone will you! And STAY OFF MY GRASS PUNK! ;-) varun ouch.. that hurt dude..what did u put inthem! Hutch I think my headphones suck. And 18 is what I made it to. Ray that was a typo I meant how much higher above 22,000, I could hear. (not 19,000. as I have already established I can hear up to 22,000.) So none of those tricky teenagers will be fooling me with their 19,000MHZ mosquito cell phone ring tones! Hey you answer your cell phone will you! And STAY OFF MY GRASS PUNK! ;-) Josh There is one slight problem. MP3 files cut off at a certain range and I don't know what that range is, but I would think it could affect the results. xmetrix 27, i can hear (or maybe feel) the 21 distinctly, and the 22 if I turn off my air conditioner eBob I am 36 and can hear up to 16,000. My dog became visibly annoyed when I played the higher frequencies, though. Dave Interesting indeed. I'm a 43YO male and i can hear 22k quite clearly. But then i can hear the bats flying around out behind my house as well. chet i'm 23 and max out at 18k .. so sad. its not like where i can "barely" here 19 either.. 18 is clear as a bell, and everything from 19 up is nothing TAPIUS Um.. im 20 turning 21 in a few weeks and i can hear everything quite clearly except i cannot hear 21KHz or 22KHz please tell me im not going deaf.. hah ( i probably am i listen to music WAY too loud and i DJ) Jim I'm 27 and can hear them all (I had to switch to my stereo speakers for the higher ones I couldnt through my monitor ones) - my dads got an ultrasonic thing in his garden to keep pests away & I can hear that. Not sure what freq that is at. Matt remember, that if you are useing crappy(dollar store/gheto) headphones/speakers then this isnt accurate. Some speakers can't play frequencys this high OSC ok. I have really nice head phones and I could hear 22,000 Hz no prob at all. Now I have to try to track down how high my head phones are able to go. When I bought these headphones I searched for the ones with the greatest range ( low and high ) . If you can't hear these dont freak out, it's most likely just your speakers / headphones. Matt Chan I'm 21 (22 in less than 2 months) and I can't hear anything above 16K through my iPod earphones. However, if I turn the volume up really high, I can hear everything. Rowan I'm a 30 year old folk musician. I heared all of the tones, but I had to crank up the volume on the very first sample. Anthony I'm 25. I can hear all of them except the 22000. If I crank my speakers, I hear the 22000, but it doesn't seem to be the right pitch. I have been able to hear electronic devices such as TV, etc. on through a window from outside the house even when there is no video or audio being pushed to the set. Will I'm only 13 years old and I can't hear anything above 16,000. That stinks! I have bad hearing, it must be because I'm a drummer. I could hear both of the first two samples near the top, so I guess that's OK. Is there a way to improve hearing or is the damage permanent? Josh Im 18 and 17000 is the last one i can clearly hear. 18000 sounds distent. I have played the drums for seven years and it may have decreased the sensitivity in my ears. Scott I'm an 18 year old male and I can only hear up to 17. jimbo92107 I'm 47, and the 17,000 sounds just like the whine of a monitor my brother used to have. I think it was the fly-back transformer doing that. Irritating as hell. I could still hear the 18K, but above that it was just a vague feeling. But I do still hear transformer whistle with my notebook turned on. grr... Adrian 17 here, can hear up to 20,000 but it's so faint that i wouldn't notice if i was in like a library. so i would say 19,000 is my limit Nate I can hear them all and I'm 24 grufo damm, i'm getting old 19 and can't here above 16.000hz. Well, last weekend was drum and bass weekend so I can't hear barely nothing kevin 16,000. Arg. Awesome entry, by the way. Abe Milde Heard them all quite clearly. Found some of the lower frequencies to be much more annoying/painful than the very high frequencies. Would be interested to see if I could go even higher. Age 32. Steve almost 41 here and to some degree -- on my Cambridge Soundworks PC speakers (they're pretty good, but VERY old) -- I could hear every one of them. Either my hearing is better than I thought it was, or the test is flawed. Wheels I'm 28 and I could hear them all no problem. Using headphones. Skawt 18 and I can hear 20,000, i can hear noise on 22,000 but it isnt a high pitched sound like the others... ? Mortimer N. Cobblepop 27 and I can hear them all, though 22's pretty quiet. The two device samples at the top are indeed annoying, and not just to youth. Kevin I'm 17, and there's a big drop between 18,000 and 19,000...and 20,000 is practically silent for me. falcon413 i'm 16 and i heard them all...must say...VERY annoying...it hurts...my old CRT monitor used to make a very low noise like those and my dad (50) never heard them...i thought i was going crazy...but i know that im not thanks to you!...((every electronic device makes these noise ...im guessing 18'000 Hz and up...i always know when something's on around the house)) Jim Ick. I tried the 15k, 18, 20k, and 22k, and I could hear all of them. I'm also 40. Guess not abusing my ears in my youth helped. My ears are still hurting from this. Patrick I'm 28 and I can ear up to 17000 falcon413 and also...u think you could post higher ones to see how far we can actually go?...that's awesome skawt ^^^^ Meant up to 21,000 an 22k is a buzz ... JW in AZ At 43 years old I can hear all except 17,000. 18,000 I can pick it up with my right year but the left nearly nothing. Through all the tones above 16,000 my right ear is more sensitive. This after more than 200 concerts so far and time spent on the streets of Athens, Greece. Jared Kipe I'm a 21 year old male, and can't hear anything above 16k. And whats sad about it is that I've lived a very low key life. I've never listened to loud music or gone to loud concerts. I have no reasons to have worse than average hearing. JW in AZ At 43 years old I can hear all except 17,000. 18,000 I can pick it up with my right year but the left nearly nothing. Through all the tones above 16,000 my right ear is more sensitive. This after more than 200 concerts so far and time spent on the streets of Athens, Greece. Thuckenstein I'm 30, I can hear them all loud and clear. Sacha 21 female, 21,000 I also heard the first sample Keith Cirkel Im 20, in a band, and listen to music with various ear killing head/earphones, and I can clearly hear up to 22k. Shame I always have to say pardon when quiet people speak. Jer I am 31 and I can't hear the annoying sound in the origional mosquito version, but I can hear it in the slowed down one. That is odd because I can hear all the way up to the 22Khz range. Sherman wow.. very interesting.. i downloaded the original mp3 to my phone.. and tested it out.. VERY INTERESTING.. im 19, and neither my mom or uncle heard it. they are in the 50's range. but yeah, it was quite fun to get my unbelieving brother to test it out. =) Tony Comment from Digg User. I'm 14, and I can only hear up to 17,000. My 10 year old sister can hear them all... Wow. ROCK First and foremost you have to make sure that your speakers or headphones can even generate frequencies as high as 22000. scot Please understand that your speakers in your laptop probably can't produce 16khz properly much less 22khz. Play the sounds through real speakers or very high end headphones (etymotic or shure). That should get you going. As a child I could hear 24khz and above. Today, I am in the 21khz range. I think i might be able to hear higher, but its hard to say. Jared It isn't just that adults' hearing will start to exclude the high end. It is, ironically, that males will tend to lose their higher pitch sensitivity, while females will lose their lower pitch sensitivity. This is ironic because women tend to have higher pitched voices, while men tend to have lower pitched voices. It's as if we've been engineered to progressively ignore the opposite sex. ;) bwatt Hmmm, I'm 36 and I can hear the 22khz clearly... through high quality altec lansings and good quality logitech headphones. Cri 22/M/Canada I can hear 22,000. Got anything higher? Face I'm 29 and can hear all of them except 22khz, cool cilia I'm 35 and I can hear them all, even though my ears were damaged in an explosion. Maybe perforated eardrums and tinitus help hearing in these ranges. Gizmo Doc I am a physcian and also a gadget geek. Just want to warn everyone that this is likely not a valid test of your hearing so don't fret about premature degeneation of your senses. Most of you are using audio cards and more importantly speakers, that can not posisbly generate the higher frequencies. I am in my mid 50s and car easily hear the 22 Hz tones as I have an audiophile system with Creative XFi Sound Card, and supertweeters that can generate sounds to 100 Hz. Aaron Saura I'm a 28 years old male, I can hear all the samples, at 22,000 I can hear high pitch wurring sound, and makes my ears feel unconfortable. Just like watching a tv or using a crt monitor so bought all lcd screens to get away from the high pitch squealing. frak I'm 28, play in a loud rock band and I can still hear the 10kHz just fine. What is going on here? Sam Its strange, but I can not hear the 18, 19 or 22k, but all the others I hear perfectly well. Just a fuzzy noise on those three. What's going on? john i'm 15 i can hear 20,000, but barely 21,000. ake I'm 25, and I can hear up to 21,000 clearly, and I am aware of, but can't quite hear, 22,000. Ron MacD I'm 59, I can hear 17K. i327 43yrs and hear all of them. I have been using ear plugs at loud concerts since I was 20 yrs. Hihi 22,000 Hz - no problem at all. loud and clear. male, 20 :D ba i can hear all of them except 15 and 18 KHz.. strange Jim I'm also older than dirt, (64) and i heard them all except 16k. Hmm. Think the file is corrupted. volume normal here. Great idea except for us with bat like hearing. Better cover the window glass if you try this on the public. Jackie I'm 21 and can't hear past 19,000. Only extremely faint beeps for anything higher than that. Jesse I could hear all but the last one. 25 year old male massage therapy products I'm 29. I can hear all of them just fine, but my ears do sort-of hurt now. Dave 15 all i can hear all of them 16 and 17 really faint, Its wierd ive blasted my music everyday on the bus ride up and back for 5 years now ive been to at leats 5 concert I thought I would be deaf by 30 Florian Krebs 24 and hearing 22kHz loud and clear. Im just thinking if any setup of speakers or headphones may influence the results ?? Jeremy I'm 21, thru one set of speakers, i can hear 19 if i turn everything way up, and through another set of speakers, i can hear 20 with everything turned way up. 21 and 22, w/ the 2nd set of speakers, i can hear, but they are lower sounds, I think just from feedback or something. Tom I kept playing the mosquito tone about every 10 minutes at work today an experiment. I could see the majority of my staff cringe each and every time. They would look around and ask if I heard it. I did, but I never let on that I did..or that I was responsible I'm 13 and I can hear 17,000 clearly but I can't hear 18,000 at all. 25 yo I can hear 22,000 quite clearly... guess some people need to turn their music down when they listen :) Cory Everything up to 21,000 is pretty clear to me - at 22,000 all I can hear is some feedback from my speakers. Oh man, my ears are ringing now. Male/19. Richard I'm a 26-yo male, and 16K is my limit. I'm a trumpet player, and have pushed my hearing to the limits far too often! Charlie Any chance we could get some lower tones on hear? I've always suspected my right ear can hear low tones better than my left. 20 - can hear all well, through 18000Hz are decently audible in my good ear - the other cuts out at 16000Hz Lacy I'm 25 and can hear the 15K, but only a click for the 16K. And now I'm sad... :-( worn 50 years and 13 KHz. (I'm sure my playing cymbals in high school marching band didn't help) Shawn These frequencies are commonly emitted from a great deal of TVs (CRTs), Projectors, etc. For as long as I can remember, I've been able to tell if a TV is turned on without any volume, even if I'm on the other side of the house. I've been accused of 'dog hearing' forever, simply because when a bad CRT is acting up, the sound can actually become visually painful to me (thank god for LCDs). At 20k, the sound is still painful. At 22k, it is just mild annoyance. I'm 30 years old. So it's not just kids. Charlie I can hear them all, male age 36. However, I have to crank the volume on higher frequencies, which is pretty typical. Now my ears hurt. Eric I'm 17, and I heard all of them. I found it weird, however, that the 16,000 Hz was the most uncomfortable. All of the others sounded fine, but that one started screwing with my head. Odd. Dante At 21000 i stop noticing, but up until then i can hear (or in the later ones, feel) them all up to there and i'm 22 Lloyd Leung I be 27 all too soon, and I can hear up to and including 21000hz with decent quality headphones. 14000hz with my crappy speakers. dub 15k is my limit reason - 38 yrs old male - roadie - (windows start up sound is too high for me !) How about graphing these results. Good experiment dood - thanks. (but u really should filter the harmonics - i can still hear those further up) Brian This is bs..i couldnt hear 17k and up with my regular speakers so i pluged in my nasty ass bose headphones and heard all of them 17 Age: 17 I can hear all of them up to 19,000 Hz. iXneonXi I'm 15. I hear all of them but I have some trouble hearing 15-18 at lower volumes. They are all noticeable though. orvl I'm a 19/m and I can hear them all, the 22,000 is the only one that's slightly dim. Phoebe I'm a 19 year old female with no hearing issues I knew of, and I went from okay 16 to silent 17. Of course, my speakers are almost as old as I am, so that could have something to do with it... Ray I'm 15 and I heard all of them loud and clear except 19,000 which sounded like silence at first, but then I could hear it faintly. The ones after that were crystal clear though. Thanks for this. ashughes I dont know if this is weird or not, but I can hear them all, clear as anything, except for 18,000. Brett Another datapoint: I'm 27, male, heard 21k loud and clear, heard nothing at 22k. I am curious though, seeing as how these are recorded in mp3, if the sound is there too. I know one effect of mp3 compression is cutting out signals above around 20k. Then again, I did get a twinge of pain during 22k. Jay I can hear all of them except the 16,000 one. anyone have any explanation for this? I'm 25 by the way. Hapax 61 years old (oldest person who reads this blog?) and 11K is my limit. I consider myself to have good hearing - can hear lots of things the people I associate with can't hear. Michael 36, male, musician (drummer) for 17 years, heard all of them. Wes 50 year old mail. I peak at 13k 14k is very faint, and nothing beyond. 82 year old father in law can't hear even 10k Grant I am 37, I could hear up to 17,000, then nothing until 24,000 (which was painful) and nothing at 25,000 Fun, Thanks Don I'm 45 year old male. I heard everything up to 15K and then nothing until 20K. I heard 20K and 21K. I had my 10 year old son next to me as a "reference". He heard everything up to 21K. Matt Age: 28 I can hear all of them till 21,000 pig I can hear all but the 22k one. They start seeming to drop in volume at that point but I do hear up to 21k. The chihuahua standing next to me ran in apparent terror when I hit the 22k one. It may help that my computer uses Yamaha NS-10M Near Field studio monitors Oh yeah, I'm 39. Grant I am 37, I could hear up to 17,000, then nothing until 24,000 (which was painful) and nothing at 25,000 Fun, Thanks Mitch 53 Ex-rock band member. Ex-DJ. LOTS of rock concerts!!! 12K is all, I can hear. Ya play, ya pay...... skunk What should your speaker volume be set at? Im sure that would make a big difference. Conquerist I'm 14. I can hear up to 21k, i can hear 22k faintly, and i can't hear 23k and above at all. Stuart Moore 40 year old male. Couldn't hear 15k at first. Took a short break while my wife tried it out (she's 35 and heard up to 16k) and then hear 15k but no higher. Amoryllis I'm 21, and can only physically hear up to 16000 (right ear) and 17000 (left ear) but all of them make my skin crawl ._. mike T-12 i can hear them all, and it drives me nuts! Herb A month shy of 38. With my very accurate Grado headphones, I can clearly hear up to 15Khz. I can barely discern 16Khz, then nothing until 20KHz, which I can hear clearly but not loudly. I can hear just about as well through 22KHz in my right ear but my left hears nothing that high. Herman Uh those of you emo freaks who think you are special and such cuz you can hear all of them: turn down your volume you retards, and try again. I'm 17 and can clearly hear everything at Max volume too, as I'm sure someone in their 80s could do... at 'normal' volume though... I'm certain most wouldn't be able to hear anything past the 23k, seeing as how 22k is the normal human threshold... I can hear the 18k very clearly, and 19k I can hear very little. This is obviously because of the harmonics as someone mentioned way up there (I was too lazy to read all the other comments) Gage I am 35 and I can hear to 20,000 that's my limit tho. None I couldn't hear sound in Sample 1 but I could hear the 10,000 Hz till 25,000 Hz what frequency did the Sample 1 sound run at? i am 20 thought Herman Oh sorry for the double post... but the check of frequency isn't associated heavily with hearing loss, that has to do more with loss of sensitivity to lower decibel sounds, at least I think. Although I'm certain that frequency is a factor, I don't think it's a big one... so uh... Also it's (again) highly subjective based on volume Jake I'm 15 and I can easily hear them all with 19,000 Hz being the hardest to hear. Stuart I am 56 and heard up to 12K....My Cat meowed everytime I turned on one of the sounds, all the way up to 25K!!! gb I'm 16 almost 17 and i can hear the entire range, muahahahaha Denise I'm 26 and if I turned up my volume I could hear the 25,000 sample clearly - although it was FAR less of an irritant at that level than the lower ones kyle they seem to get quieter the higher up the pitch goes Matt At 16, I could hear all of them VERY clearly. Gary I'm a 65 Y/O male. I can't even hear the 10,000 hz, the tinitus is so loud I'm lucky to hear my wife scream at me. I was a radioman in the Navy, taking Morse Code to 38 wpm. But that was in the 60's. Th I could hear up to 16000 with my speakers but my headphones would allow me to hear all the way up. Don't the speakers matter? Some don't have the ability to go too high or too low. ronka do you think your standard media-player/speakers/sound-card can handle frequencies more than 20KHz ? so maybe a lot of you couldn't hear it because of hardware or software limitations ...? i am 25 and I could hear till 20K clearly and 21k only after raising the volume way high on Windows media player and a pair of regular headphones. Greg 18, and can hear up to 25,000. Dennis I am a 14 year old boy. I can barely hear 25,000. 23,000 is the best for me. Art 42. I hear up to 14, then nothing 'till 20. THen I can hear it again. John Bokma You can not test this by just downloading mp3 files. It depends a lot on your audio set up. I can hear 25 kHz here, which sounds lower compared to 20 kHz, so go figure. If you really want to test this, use the right equipment. Tim Just turned 30, can hear till 17k (painful) and then 22k and higher sound like lower frequencies... I was confused but I think it's because my headphones support 12-24k, while the frequency response on the transmitter (they're wireless headphones) says 20-20k. Still, not sure why I'm hearing a lower frequency at those levels (after cringing on 17k I'm glad I don't hear 18k+). will (14 yrs) I'm 14 years old...and at normal volume I can hear 18-19k. Damnit. Adrian Uhh, 44.1khz sampled digital stereo sound can only go up to around 22Khz and yet the 23-25k files here are sampled at 44Khz... And actually, maxing out 44.1Khz sampled files (at 22Khz) just results in a square wave or a near square wave which generates lots of harmonics and other noise... which then amplifier circuits and speakers round off and change in strange ways. You can often hear the noise and harmonics and mistake that for actually hearing the frequency. Most computers with built in sound can't generate anything that high anyway... Get a 192khz/24bit sound card with good speakers and amps and try it again. Kel I am 48 (had to do the math real quick). I completely lose it after 17,000 hz. I can still hear the 15,000 hz tone still now. It's great though, because I have now identified that my old TV is at 15,000 hz and my wife can only hear to 14,000 hz! Great site, helped me prove my point that the TV whistles all the time! Can you say "New flat screen"!! synack 21 here and I can easily hear all of them. the 10,000 hurts my ears really bad. I didn't even think my hearing is that good... Weirdbro Will, you're getting old fast. I'm 14, and I can hear all of them. aerotive I'm 31, male and hear 10,000 and 11,000, but nothing about that. Jake Wilson I'm 16 and i could only hear up to about 16,000. Iguess my ears really suck. Anna I'm 21 and can hear only up to 17,000Hz... Could it be the ipod??? Ryan what people dont understand is that you cant do this purely with speakers, you need a totally silent environment and some nice headphones that block ambient noise to successfully test your limits Holli I'm 22 and the highest I got was 23,000. Connor Frig! The 19 one killed my ears! I can only hear up to that. I am 14 Wayne Unintentionally tortured our cat. Found her in another room, sitting in the corner, facing the wall, as if she was trying to get as far away from the sounds as possible. craig 56 and heard all ranges clearly although they may be mislabled?? Even sample one. Huh? who said that? oh it's you god. what? oh yeah i think humans are worth saving. Brandon Im a singer, and I can hear them all the way to 25k, but its ear piercing on the sample 2 BTW im 25.... dont repel me. i have money to spend in your businesses Don't feel too bad if you can't hear all of them. Your computer speakers may be the problem. Mike "Herman Uh those of you emo freaks who think you are special and such cuz you can hear all of them: turn down your volume you retards, and try again. I'm 17 and can clearly hear everything at Max volume too, as I'm sure someone in their 80s could do... at 'normal' volume though... I'm certain most wouldn't be able to hear anything past the 23k, seeing as how 22k is the normal human threshold... I can hear the 18k very clearly, and 19k I can hear very little. This is obviously because of the harmonics as someone mentioned way up there (I was too lazy to read all the other comments)" I heard all of them, at the same tone of what i have my music at usually. Kev Well I guess my ears survived my teens, I'm 29 and can still hear 25,000Hz, can't say I'd want to again. insertyp0 Since I first read about Mosquito, this is exactly what I was looking for. Thanks Corey I could all of them easily. Even 25000 was easy for me to hear. I'm 14 years old. RaistlinMajere 29, can hear 17,000 and below. Cannot hear anything over 17,000. rob im 26 years old. i can hear every frequency very clear. am i doing something wrong? whats the point? James This is deceptive, because most computer speakers cannot accurately reproduce sounds above 19000. My speakers clearly state their range is from about 43 to 21,000.... yet I could still hear the 25000 tone and I'm 24. Drew Chapin This was very strange, the highest frequency i could hear depended on which program i was using to play the file... here's what i found... WavePad - 17 kHz RealPlater - 18 kHz Windows Media Player - 25+ kHz Nero Showtime - 25+ kHz QuickTime - less than 10 kHz JSR9816 I can hear all but 16000, 21000 and higher i can hear 20000 barely Brett I want to amend my earlier results. I think it depends on the speakers. When I was listening in my headphones, I think they were either giving harmonics, or my headphones weren't responsive enough. As I inched up, it would occasionally drop in pitch and I misinterpreted the results. 27 Male: 19k just fine, 20k with the volume maxed. Felipe cool im 30 and i can hear all the freqs. Joshua Scrivner I'm a 15 year old male and I can hear all the way to 25000. Geoff 17 years old and can hear every sound very clearly. Adrian 28 Male I heard up-to 17kHz with a sharp distinct ring (gave me a mild headache listening to it), anything above that gave me a slight throbing buzz at the back of my head. Not sure if it's my current setup (crummy HP laptop listening on Apple iPod earbuds) but I'm gonna try again when I get home where everything is hooked up to a High Fidelity System. rob f. I am 33 and I could hear all up to 22,000. which is a bummer because I do remember hearing that tone before on a hearing test and now I can't hear it. djeb I am 38 and have been making music since I was 14 or so. 15,000 is my limit. But i have always had bad ears and loud music don't help none. BUT my ears are the same as when I was 15 or so when i had my hearing checked. I have always had a drop off in the higher levels. Not that i miss those sounds :P kyderdog Well I guess I am old (45) I can only hear up to 13,000 Hutch 14 and I can only hear 19,000 :-( Christopher ZOMFG! I can actually hear 25,000 Hz. Pwn! Dwight Hanson I'm 59 and only hear12K Those are Mp3s Mp3s are compressed files, what you are hearing is not the sound but the artifacts from compression (white noise) Try using .wav's instead i'm 22 and i can hear them all Elliot Wow this is very interesting. I can hear up to 17khz. When its at 17khz it sounds like my ears are rining. 18khz is nothing for me. My brother cant hear 14khz @_@ Pretty interesting stuff. br0d This test is not entirely accurate. Firstly,these are mp3 files. mp3 aliases above 15kHz or so as a part of its compression scheme. So these are not accurate representations for that reason, anyway. Additionally, since these files are all sampled at a rate of 44.1kHz the Nyquist frequency for this rate is 22050, which means the rate is only capable of 22050 samples per second, and all the examples over 22000Hz are bogus. In fact, if you download the waves and look at them, 23kHz, 24kHz, and 25kHz are identical. 22050 is the ceiling, this only tests up to that point, and that is if you discount the mp3 aliasing. For them to be accurate they would have to be sampled at 48kHz or preferably 96kHz, and be would also have to be represented in uncompressed .wav or .au format. I am br0d and I pee in your ice cream. Angela I played the 15,000 in a room with my huband and three sons. The older boys said "AAAAHhhhhhh!" the baby whimpered, and my husband didn't hear anything at all. Bwahahaha! Gman It's not often someone tricks me into listening to 16 sequentially more infuriating noises. Well done, asshat. :P In the event that any pretty girls were wondering, I'm 20, devilishly handsome, prone to taking long walks on the beach... D 15 male, 25000Hizzles Lauren I am a 23 female and I can hear up to 17,000, but not 18,000, but then I can hear them all after that. That makes no sense! I do have a harder time when I reach about 20,000 though. I can definitely "feel" the sounds, too. I know when my tv is muted and I leave the room, I can still "hear" it. I also blast my ears out a lot, so maybe I am just lucky! Oh and this is strange since everyone tells me I never hear them... Elliot Dude im 15 and I cant even hear 17KHZ Gman It's not often someone tricks me into listening to 16 sequentially more infuriating noises. Well done, asshat. :P In the event that any pretty girls were wondering, I'm 20, devilishly handsome, prone to taking long walks on the beach... Dan I'm 24, i can hear the 18k very clearly, but not the 19k when i use a pair of USB headphones, using my computer speakers i can hear them all (but i don't think it's the actual frequencies... just the speakers being confused) Speakers aren't designed to handle frequencies higher than 20k, and MOST can't even get up to 20k. Wespog many of you said you couldn't hear 16KHz. That's the frequency at which women complain at. Congratulations, you have adapted to filter out the unnecessary. Enjoy it. Gman It's not often someone tricks me into listening to 16 sequentially more infuriating noises. Well done, asshat. :P In the event that any pretty girls were wondering, I'm 20, devilishly handsome, prone to taking long walks on the beach... Dustin I would have to agree that this is inaccurate. In a physics class i took last semester, the professor did an experiment in class, and i could still hear it at 22000 Hz where his machine supposedly maxes out. i could only hear 18000 in these files. Psyonic It might just be my speakers... but I lose hearing at about 20000, but then after that I can hear some sound on each file, but its not the right pitch. Any idea what is up with that? Stuart Moore Just tried it on my 4.5 year old son and he heard up to 21k. 3pe these samples suck. Most modern soundcards won't play it correctly above 11000Hz because of sample rate usually is 44100Hz, and the mp3 lossy reduces these higher freq's to their lower harmonics. What you hear, after 11khz are the faulty compressor's noise. :PPPP Try regenerating this waveform, like 22050Hz using 44100hz sample rate, and 99.99% of you won't hear it at all. Maybe a cat or a dog, little animals. Howard I am 50 and can only hear up to 13 khz slickeddie I'm 23 and I can hear all the sounds. could you go up to 30k or even higher? i want to know how high i can hear Gman It's not often someone tricks me into listening to 16 sequentially more infuriating noises. Well done, asshat. :P In the event that any pretty girls were wondering, I'm 20, devilishly handsome, prone to taking long walks on the beach... BWilde Not a meaningful test, who says your speakers/earphones reproduce those frequencies at all? And if they do, is it flat response? Or are there peaks/valleys in the response? Dj ANTi Depends on the computer you are using. On the computer I first tried at school, I could only hear up to 16k. On my Mac, I could hear up to 19k. Now I'm on my HP, I can hear all of them. =[ Still cool though. Chris im 22, almost 23, i could hear up to 16000 cleary 17000 i could hear not as much as 16000 tho Mike 20 and I can hear all nice and clear. Also I can hear TVs that are on mute. Its somewhere above 20k cause no one else hears it. I've always heard our TVs and many others while on mute or on a static station. But CRT computer monitors are fine. Gman It's not often someone tricks me into listening to 16 sequentially more infuriating noises. Well done, asshat. :P In the event that any pretty girls were wondering, I'm 20, devilishly handsome, prone to taking long walks on the beach... Amit 21000, 35 years I'm 29 and I heard 19 but not 20 dodo 33 male and can hear the 25kHz no problem.... Asiaerotica.com I am 51, I used the Sony MDR 7506 Pro Headphones, and set the vol on my sound blaster platinum pro card to 1 bar below mid level and I could hear/feel a distinct kind of annoying sound up to the max 25,000 I noticed that the pitch/tone was different frequency to frequency. Robert I'm 20 and I can hear all the frequencies just fine, as well as something odd about sample 1 slowed down. I don't know if anybody else heard it, but I heard someone laughing in the background and then a tapping, like a stick tapping on a table in the background. Please someone listen to it that can hear very ewll and tell me that I'm not insane Geoff I'm 43 and I could hear 14K. One thing to remember, tho, your soundcard/speakers/headphones may not reproduce these high frequencies well, so there may be some rolloff in the amplitude of these sounds as the freq increases. Or, I'm just old. ztepf Eh, well people are right about the format used for this experiment. However, I still feel justified at the years of bitching at my ma for her shitty TV which always pierced my ears and made me want to wield barstools (that would be the 18k Hz sample). 21 here hear Nelson I'm 41 and could hear 'em all. Could it be the speakers I was using? Hmm. Maybe that nurse who checked my hearing upon signing up for the military all those years ago was right. He said my hearing was below and above normal range... from another galaxy I was able to hear frequecies that were even not listed ... let alone these! Jokes apart ... this is a good one ... surely you deserve so many diggs John 2100, 55 years old. The higher ones still have some audible harmonics, but not the tone. I have always said I am noise sensitive. Who ever invented amps and huge speakers for cars should be subjected to a frequency that drives them mad! Topher im 14, and i could hear up to 25,000, but once i got to 22,000, they all sounded like the same pitch, only 22,000 was a little fuzzy sounding. and on the first sample, i could hear it just fine. Dirk I heard them all, but I think that has to do with a nasty harmonic between the sampling rate of the mp3 and the actual waveform. i.e. they did not sound like they were ascending in pitch. Additionally IIRC mp3 is a poor way to encode high pitch sounds, so maybe you should clean these samples up a bit and post them as something lossless like Ogg or WAV? Chris 23 year old male, can't hear anything above 15,000 :( I find it hard to hear people in noisy pubs and other loud places too.. DW I am 2 years old and I can hear to around 5MHz Daron I'm 43, and I max out at 19K, and I have to turn it up a long way to hear it from 16k onwards. Above 19K, I can't actually hear it but I still seem to want to screw up my face and wince while its playing. I guess all those years in the Metal band didn't wreck my ears after all ;-) Deaf Bastard I'm 36, and must be fucking deaf. I can't hear a bloody thing past 13,000 Mike I can hear all of them. But then again, I am 13. Oh, the joys of being young. James w00t! I beat you ;D 20, 000 :D matt pretty sure i can hear the 20K, not 21K, i'm 23 too. you have to factor in the possibilty that your speakers/ headphones can't play these higher frequencies, at least not the same level of those lower frequencies eevee could hear up to 19000, I'm 22. never thought about hearing frequencies before though as a child I remember hearing very low frequencies and my dad thought I was nuts when I'd ask him if he heard anything. Belenus Ok well im 15 and i can hear every one perfectly. Although, I do doubt your last three samples because they all sound like they are the exact same frequency to me. Maybe they just sound similar, but you may want to check that out. Ivujivik call me fucko, but i can hear them all, sowhat does tha that make me? jerkoffs?!? chase i'll be 31 (turn 32 in july), and i can hear up to 17000. catfriedrice 10-21 fine. 22,000 was mentally irratating, and I could tell a difference in the room by the time the sound clip ended. Both samples, I could hear, though #2 pulsed in and out. catfriedrice and I'm 22 Skylab As several people have posted, this test is deeply flawed. Sorry. The "samples" at 22-25 kHz cannot possibly be those tones, since a 44.1 kHz samples digital file cannot possibly reproduce them. Dave i heard them all up to 22000, i played them on 2.1 speakers lunarnall I am 15 and I can hear them all... I can hear them just fine. It's kinda weird that I won't be able to hear them in 10-15 years :[ Arlen 15, can hear every one! I shouldn't be surprised, I guess. DJ Rais I can hear 15,000 clear, but not 16,000. Neither me nor my son can hear 17,000 while he can hear 16,000, but he is only 12 Mike Some of the higher frequencies (above 22) gave me a tremendous headache. Must lay down now. TJ Male, 41, can hear OK to 25K, but 13K is oddly weak. Yet I have real issues hearing on the phone. ...but I can hear the neighbor's phone ringing two doors down when all of our doors are closed. Weird. brad 33 and can here them all... basak I am 29, and unfortunately, was able to hear all of the samples; in fact I am able to hear very high frequencies, which makes me crazy!Sometimes, I wonder how it feels like to be deaf.. Erin I'm a 20 year old female and I could hear up to the 20,000 Dave I'm 17 and can only hear to 18, barely. That's what I get for listening to the loud music :/ I wish there was a way you could excercise this, but sadly once it's gone, it's gone. mobtek 34, can barely hear 16000 or 17000 but I can hear the ones above that :) Wesley I can hear all of them. But im just sweet like that. Im 18 by the way. oliver i can hear them all and im 15.. Guinevere 31 year old female and I could hear all of them, which is encouraging 'cause I thought my hearing was getting poorer. Well... maybe it is, maybe I could hear even more before. Tim I don't know what the big deal is. I'm 21 and I can hear 25,000 fine. Do you have any higher frequencies. I'll bet I can hear 30,000 HZ. Please give me a CHALLENGE. CR UVa Currently 22 years of age, Not only can I hear at 25khz, but at such a high pitch actually hurts my ears more than at lower pitches such as 19khz don I'm 39 and heard them all just fine. joe k I could hear all of them except 19,000... wierd. I'm 24 op age:24 i can hear all of them clearly C Female and 21, and I could hear them all just fine. 12000 was particularly annoying for me, but 17000 was absolutely *painful*. The rest didn't bother me at all. In fact, they were almost quite soothing after the one at 17000. Dean I'm 38 and could hear all of them clearly including both Samples - though Sample #1 was a little faint. Makes me feel good as I used to listen to music at very high levels. Bet if you had some test sounds in the freq. of computer fans I would be deaf to them as I work with computers all day. joe k funny thing though... now that i've listened for all of those... i can really hear the neon-light in my fishtank.... and it hurts my ears... Mike Any link to a free spectral analyzer? 27 and hear up to 25 fine but can't distinguish between 20-25 Stephen There's normally a M/F split with hearing as well, with F hearing higher frequencies. I've never understood how people can watch PAL TVs for any length of time, they have a pretty low frequency whine to them, to me. 34M, 18000 over laptop speakers, 22000 with headphones. I've always preferred detailed music over loud music, which has probably helped. Paul W If your running at 44.1 it's impossible to play back a frequency above 22.05Khz. Trying to record a frequency above 22.05kHz will just cause aliasing at 44.1 What sample rate did you use for this test? Jimmy Way cool. I might make a flash test about it and submit to newgrounds(with proper credit). I am 20, have very good hearing, and can get up to 17,000 Paul W I suspect this test is flawed Jerry Seinfeld I'm a 130 and I can hear both sounds perfectly fine. The first one is horrible, the second one is terrifying. Felicia Female, 49, and I can hear all of them though I had to really crank up the speakers to hear the 16K bstrom Most speaker systems are too cheap to reproduce sound up as high as 20,000. This test is faulty. T-T-T-Toni Im 13 and i cna hear all :D I Accually put one on my cellphone and sat beside the teacher and let the ringtone go off... he dident hear a damn thing ^^ Joe I think my hearing sucks since I listen to music really loud over my headphones. However, I can hear all of the mp3s just fine. anything above 20 makes me jerk my head a little (as if the sound is very strange). Mark After I listened to the first one, I had a ringing in my years that would prevent me from clearly saying where my sound threshhold ended. Beyond that, I'm not sure if my cheap headphones could actually produce anything higher than about 16,000. I'm 27. noguerol I could hear up to a very, very subtle 18k. 19k make me suffer a kind of horrible head preasure and above that I can't hear or feel anything. I'm 21 years old. studman I'm 22 and can hear everything put up there. nein 24 years old. can hear up to 19, not 20. Rob We did this in high school 27 years ago. I could hear >21000, best in my class. Now I can hear them all! I think this is might be a test of how computer sound cards and related equipment process digital information. Stormer 42 and can hear them all. Great speakers and great amp hooked to the computer though. Normal listening level for volume. Say similar to keeping radio low for our parents when we were younger :) Tried headphones, same thing. So guess I still have good hearing. Now at least I can explain to my friends why I hear something and they don't :) Afrotronics Theo you see the problem with MP3 files is that frequencies a human usually can't hear are nixed out of the file (this is one of the steps to compress it) another problem for everybody is the frequency response of your headphones, speakers or whatever you're using to hear this may not be able to vibrate effectively at such high frequencies. Now remember to eat your JELL-O pudding daowwwww! Aaron Remember that some hardware (sound cards, speakers, headphones) may not be able to correctly reproduce the frequencies above. Britt 18 years old and I can hear up to 23000. noguerol I could hear up to a very, very subtle 18k. 19k make me suffer a kind of horrible head preasure and above that I can't hear or feel anything. I'm 21 years old. Kara I'm 18, and I could hear every single one of them. eryksun As others have pointed out, this setup is invalid. The files aren't sampled fast enough for frequencies over 22k. Even if they were, a lot of PCs use DACs that roll off in the 18k-20k range. Also, many speakers roll off rapidly above 18k. If you need to check your hearing, consult a professional audiologist. I wouldn't be too concerned if your hearing sensitivity drops off above 15k. You're not missing much -- except maybe that annoying 15.7k hum of a TV's horizontal refresh. Brandon im 16, and i can hear all of them, plus a 26k that i made - my parents could hear around 17k, they are 40 & 43 eryksun Oops, the >20k samples are sampled at 96k in wav format, so my first comment doesn't apply. But my comments about the DACs and speakers used with typical computers still stand. Claude I'm 33 years old. I can hear all frequencies quite easily. However, 23 kHz, 24 kHz and 25 kHz sample sound all the same to me. I guess my soundcard is limiting frequencies or something. andy I'm 16 and 17k is the highest I can hear. Ryoko I am 18, and can hear all of them. But after 19 or 20, I would miss it, if I didn't know what to be listening for. anthony Hi, I listened to samples on cheapo pc speakers and now my ears keep ringing aftewards. They normally do this but it's only noticeable in a very quiet environment but now it's over the top of everything. Hope I haven't done any damage. Incidentally, I am 36 and could hear up to 19000. Jesse I'm 20 and i can hear up to 21,000 Hz. thought the sample for 25,000 Hz was a scam but i turned up the volume and my cat bugged out so it's legit. John Portman Adams I am 126 years old and I can hear up to 3kHz fine. tessie I am a 45 yo female. I have had a stapedectomy (replacement of bones in my middle ear) in one ear due to hearing loss. I cannot hear anything above 12K even with the volume up all the way. It's kinda fun because it really drives my 40 yo husband crazy when I crank up the volume on these. But the 13K sound at full volume made me feel like my head would explode, even when I couldn't hear it. Charlie Any chance we could get some lower tones on hear? I've always suspected my right ear can hear low tones better than my left. 20 - can hear all well, through 18000Hz are decently audible in my good ear - the other cuts out at 16000Hz digimom I found this most interesting ;-) I am 72 years young, which in itself is quite interesting ;-) I could not hear 10k, 11k, or 12k, I could hear the 15k, 17k, 22k and the 25k The remainder I could not hear. digimom Addendum: I was using earphones only. Peter I get an internal stream error whenever I try to play anything above 20k but I can hear all of them up till then. I'm 27. Kurt I just turned 33 and can hear up to and including 14000 but nothing after that. Can someone start a graph chart and link to it with the results from everyone here. It would be really cool to see the averages. Paul W You also have to remember that the listener has to play the files back with a 96kHz sample rate. Forget Mp3. Post shorter clips of 96kHz wav files. And make them mono. There's no point in wasting bandwidth on stereo. At least this way peeps who can run at 96kHz can play them properly. Anyone with a lesser sample rate forget it. Paul W ""A guy in England figured that meant kids can hear things adults can't - specifically, very high frequencies. He created a device that pulses an annoying tone at about 15,000 Hz with the idea that when the device is used, it will repel kids while being unnoticed by adult"" I'm from England. I saw the news report on it. It's flawed too. Loads of adults can hear 15kHz. I'm 46 and can hear upto 17kHz. I would be well pissed off at 15kHz blasting away. :) :) Greg I can't hear any of them. My computer is too loud!!! Paul W ""Felicia Female, 49, and I can hear all of them though I had to really crank up the speakers to hear the 16K" never crank your speakers to try and hear high frequencies. You can damage them - seriously. Dave With speakers I couldn't hear past 14000. With headphones, I could hear up to 20000. Oh by the way, That 18000 sounded more like 18037 to me. Jon I am 17 years old. I can hear up to 22000. :) Daik I'm 20 and can hear up to 21k but after that I have trouble. I don't hear the ringing, although there is quite a bit of ambient noise, like air. Daik Actually, if I crank up my volume high, I can make out all the sounds...although that's probably cheating. Dave 20k male 23yrs holland ^^ John I am 56 and can clearly hear up to 22,000 but I had to turn up the volume on my headphones to do so. I am assuming this is a test of what frequencies you can hear so upping the volume is ok. Strange part for me was that lower freq's sounded much higher in pitch. Thought it would be the opposite to this. A Finn Thanks to the Finnish army I can not hear anything above 13 000khz.. 32 male Thanks a bunch sa int. Mike I'm 20 and the highest frequency i could hear was 19,000 Hz... Too many concerts. matt arizona, u.s.a. 27 years old. up to 16,000 Johnny I'm 15 and I hear all of them.. Bothersome to say the least. Dan I'm 25, I hear all the sounds fine though some are far more difficult to detect than others. gerald 24 years old. i can barely hear 15k i have some hearing loss i think from loud music/playing guitar as a kid. i'm also only listening to them with one earbud headphone. maybe that affects the results i'm not sure Kualla This testing really doesn't matter much unless you know your speakers and sound card are capable of reproducing the sound waves. I wonder if THX certified speakers can fully reproduce all of the above frequencies, anyone know? xoc This doesns't count for much. People's sound cards and speakers will make more of a difference than their hearing. The only way to be sure is to have a mic record what sound is being produced to ensure it is of the right wavelength and intensity. I can clearly hear 17k with one set of speakers, but bearly hear 16k with a set of headphones. rasika im 21, and i could perfectly hear everything - from 10k to 25k, is that abnormal? Dan No it's not normal. It means either you're lying or you did the test improperly. hmmm im 23 and i cant hear anything AFTER 17000... am i tone deaf? Z i could hear up to bout 21000 Martin Male, age 33 and can hear all except 24000. The mosquito buzz can be heard for about five seconds then I cannot distinguish it from background. I used closed ear headphones and another test round with my external speakers. the 4400 I'm 25 and I can hear 10-19000, with no problem. 20000 and 21000 I cannot, and 22000 makes me want to cry like a sad panda. RiSE Whatever ones i couldnt hear my dog could! he was giving me funny looks! Cool Site Patrick I am twenty-two years old male. I can hear up to the 22,000 Hz range. No discomfort what so ever. rick age 30 ~ all but the last one. Osc I am 56 and could hear 17000. I feel pretty good about that! Can't see worth a flip though! tony 38, can hear 16k but not 17k. Steven St.Clair Im 24, I could hear them all I used to be in the military and I would always get PERFECT scores on the hearing tests as well. tony 38, can hear 16k but not 17k. Julia Almost 20 years old and the sound was gone entirely by 16K. Ian I'm 23 I can hear every one of those perfectly. I felt like I was doing something wrong so I even put my volume at 9% and could hear them all. And I'm not using headphones. Am I a freak? Feel free to e-mail if science needs to run tests on me: sample @ magick . net hahah =O Ed I'm 56 years old. I could not hear 16 or 24 but the rest up to 25 were clear as a doorbell using external computer speakers. Can you hear me NOW ? Ray 37, and can hear all of them up to 25,000. but 25,000 is hard to distingish with the household A/C running but with out it I can hear it clearly. Pretty interesting stuff, the brain and the ears in concert. So I guess now I am officially part dog! I would be very interested to see if someone that is blind is actually more hearing sensitive than a sighted person. ;-) max I'm 14, and can hear up to 1600 with exreme discomfort, headaches. I'm a little dissappointed. Jason I'm 31 quite shortsited but at least my ears can detect 23khz.......conolation prize :-) Marion Almost 18 and could only hear to 18k. Although all my senses are quite bad. =S Oh well. Julia (again) Funny, now I can hear 17K actually. And clicks at the very begining of the next few after that. Julia Almost 20 years old and the sound was gone entirely by 16K. Stephen 26 and can hear the 20,000 as well as the sound in both clips clear as day. Stephen 26 and can hear all the way to 25,000 as well as the sound in both clips clear as day. Daddio I was able to still hear at 20K, but after that I couldn't get he files to load so I don't know where my threshhold ends. I am a month short of 53. I and my parents have all had hypersensitive hearing. We could hear the ultrasonic burglar alarms when we went into certain stores including our own. There was never a day when the alarm was accidentally left on as we would all writhe in pain from the piercing sounds it emitted. I was even made to stay overnite in Chicago when I went for my draft physical in 1972. I was continuing to hear at over 35K and they though I was lying and pushing the button to piss them off. After the second day of intensive testing, they were convinced I could hear like a bat.

Zipz Is i more or are the mp3 broken or somthing because my mom,brother,and i can all hear every single frequincy. JF I can hear the 20k frequency, but my soundcard won't go any higher. I will be 29 in less than a week, so I guess that it's not too bad. Just wish I could test the others without that annoying "Internal error" message my soundcard poops out. (Laptop....) 22 can hear up to 23, but 24 is nothing, hear the sound in both files Tam can hear 18000. and im 16 years old blinc hmm.. try turning up the volume.. is that cheating ? Tam hmm that comment up there turned out wrong O_O ..i can hear 17000 but not 18000.. and yeah im 16 yrs old. gurl 19yrs i hear 10 to 20 but not 21 to 24 and i can hear 25.. isnt that weird? claire i can hear 17000 really well but cant hear anything of 18000 which weirds me out because of the abrubt change. claire and i'm 17 noblogger 17yrs and 19000hz fine Amanda I can hear the little click thing at the beginning of all of them. But for the pitch thingy, I can hear up to 19,000, and I'm 2 months shy of 16. I need to put away the iPod. Hunter Am I supposed to listen at a certain volume? Hunter I can hear up to 23,000, but I can't hear 19,000... ? I'm 14 years old. Antoine I can heat up to 22k hertz. It helps if you have headphones. btw - 19k hertz makes me feel woozy Antoine ps btw, I'm 31 rock 58yr male.Can hear at 14k but at 15k need full volume and head in right position. rock ..at 19yrs threshold was about 16-17k.-well below 20k anyway Jo Giraerts I'm sorry to say so, but those sounds are FULL of harmonics. these aren't clean xx000Hz tones. The fact is that with these files, you hear a lot more than when you hear the actual frequency. For instance: i (28 yr old male) can hear every file until 24000 here. But if a take a tone generator (for the GNU people: gnusound has one in the Tools-menu). I can barely hear the 18000 sine wave. Adrian Wow.. good site. I can hear up to 19000 DJ D I just turned 31, and I have been a professional Club DJ for over 14 years. After testing a few of the places I work in at 130DB+ I expected to be deaf, but I am glad to report that I can hear everything up to 21,000 very clearly. Raymond Can you generate frequencies down to 20Hz? Seven I agree, lots of harmonics... A bit misleading at 20k+ as they can be wrongly 'heard'. ...but 24 male and just shy of 20k. Great Site! Jay Im 16 and can only hear upto 16,000 Hz that is really worrying. Will I go deaf early. or something. Thanks Jonathan Ross I'm 17 and can only hear up to 16,000Hz. Must have been to too many loud gigs... or just deaf. Who knows. Nutty 43, musician, everything but 16k Hz! Good to know this for next time I'm in the studio. Actually I can't easily play the .wav files so I didn't test the 21k Hz and up. (yes, on a mac) Thanks! Cory I can hear everything up to 23 easily, but nothing after that. Ramizan This is cool. Doubt my speaker can take it cause it doesn't sound properly above 22k. Man, I need a cat to test how much it can bear with this high pitch sound... :) Ankur Patwa I could hear upto 23k in increasing order. but once i had gone to 23k, i went deaf for 18k to 22k. i think that was weird. The test was fun though. Sagittarius I can hear the 25 Roy One of my 5.1 speakers started spewing up smoke. Is this normal?! Eyal Don't despair if you can't hear high freqs. I could hear up to 16K with my PC speakers, but then I checked with headphones and got up to 21K. Sebastiaan I'm 18 and i got to the 24000 , I also heard a sound in the 1st sample, it wasn't annoying, I could bearly hear it. Funny test. joey that first clip was extremely irritating. it made me want to break stuff, or claw at my ears. anything to make the noise stop. i could hear clearly from 10k to 20k and not much above that. 25 years old. garth got as far as 15,000 before it went blank. sweet, good job tom I'm 21 and I could hear it loud and clear at 16k, but couldn't hear a thing @ 17k. I also have the TV on, which I know puts out a tone somewhere around these frequencies too. Hihi Update: 25,000 Hz - no problem at all. loud and clear. male, 20 :D Aficionado 29 and heard 18,000. Are we dogs? Why would this drive anyone out of a store? DeeB This seems insane. They are increasingly annoying up to 18k, then 19k-21k are totally inaudible, BUT!... 22k-25k come in perfectly clear and are NOT annoying in the least. For the record I'm 23. sudi am 33m, could hear clearly upto 17, and just clicks uptil 20 i work and live in relatively in quiet environments ash As bboy has already pointed out - the test is flawed. Dustin I'm 21 and could hear up to 19k Matt what quality are these recordings.. can hear them all quite well, got a feeling that aliasing is happening though where higher frequencies are captured or resampled as lower ones because the sample rate isn't high enough.. for the 25Khz one you need atleast 50khz, this is why audio cds only capture 22khz. Plus using headphones would be a better test, most cheap headphones can do well above 25,000 some as high as 40,000.. might explain why some people are hearing the apparently higher pitched ones and not the lower because they aren't actually lower!! Matt Bboy was pretty much right.. didn't see that post before commenting, although they aren't lower harmonics because theres no such thing, a harmonic can only be higher in pitch than the fundamental tones, its caused by alisaing as I mentioned before... flawed test... Jayden I'm 18 (19 in two and a half months), and I could hear up to 24,000 with no problem. Brian EB I'm 31 yrs old and at first couldn't hear above 15KHz, but then when I turned up the volume to see if I could annoy my dog, I could hear up to 17KHz. It was cool to read that I wasn't the only one feeling physical discomfort at the higher frequencies that I couldn't rightly claim to be hearing. I thought it might have been a psychosomatic reaction. I felt like I was "feeling" 18 and 19KHz in my head, rather than hearing them. And it was not a pleasant feeling. Antonio I'm 26 and can hear a weak buzz in the 24KHz sample but not as loud as the 15KHz one. 25KHz appears totally silent to me. E I'm 26 and can only hear through 12000 clearly -- I can just make out 13000 on the very edge of my hearing. I'm already undergoing investigation into my hearing, but this convinces me even more that there's something very wrong. Joel I'm a 32 year-old male. Can JUST hear the 19KHz and MAN is that annoying. Gets right inside you. Amigajoe http://www.softpile.com/Education/Mathematics/Review_21743_index.html -This is a link to a software frequency generator that produces pure tones for a given freq. Much more accurate than the samples. Turns out my hearing isn't as good as I thought! ;-) Marcos I'm 40 and I can hear them all. From 20k up, it turns from a loud whistle to a buzz. I can always tell when the TV or the computer is on, even when in mute. Up to 20k, the sound would make me leave a store. Shadoan I'm almost 32 and have played in bands and loud music for years... so, no surprise, can't hear over 12 without turning up volume... so 13 is there, but not clear. Mac I can hear up to 23khz. 17 is quite noticeable and I'd love to see one of my kids try to sneak a ringtone like that around me. The lower rages hurt my brain some kind of awful though.

Turns out my hearing isn't as good as I thought! ;-) Yaa101 I am 39 years old and I am able to hear 20KHz with a dip round 18KHz, this is with a normal sound volume and louder. PM I'm 36 and can hear 20,000 clearly but not 21,000. TDub There appears to be a gap in my hearing. I can here 10k-21k, 23k and 24k. For some reason 22k is inaudible. Not hearing 25k is understandable. Claudius Jensen I can hear up to 60,000 hz, I know it's pretty amazing. My doctor said that he's never seen anything like it before. Claudius Jensen I meant 60,000 KHz Evil At first I couldn't hear clearly up to 16k and at 17k I could tell there was a sound, but it wasn't quite like hearing it. Above 17k I couldn't percieve anything. Then I had a thought; maybe my speakers suck... I unplugged the external speakers I had plugged into my laptop and listened to them on the laptop's speakers (both have the Harmon/Kardon name but the ones in the laptop are ~8yrs newer). On the laptop's speakers I could hear 17k clearly and percieve sound all the way up to 20k. 21k wasn't like sound, but it made my head hurt. 22k + had no effect on me. FYI, I'm a 34yr old male. Claudius Jensen D'oh, sorry. 60,000 Hz dave 34 y/o male and can't hear 16,000 or higher Jaka i am 16 years old and i can hear up to 16 000- i dont hear 17 000 Gem I can hear all of them EXCEPT 19 and 20,000Hz What on earth does that mean? Ed I am 33. I have be an audiophile for 15 years. Many years of loud high quality music. Now I know why I enjoy the quality. I can hear 23k but not 24k. That's fine with me. Manwolf 51 and I can hear up to 20k before my speakers drop out. Marc I can hear everything! and im 14 Carla I'm 38 female and I heard up to 20Hz. The 15Hz sounds just like the tinitis I have had since birth. Adrian Posted earlier, turns out indeed my HP laptop sound card is crap. Back home with my Hi-Fi setup all's good up till 23kHz. At 28 years of age, I think that's decent enough. Also noted that at higher frequencies background harmonics are drowning out the main signal, this is very likely due to the lossy nature of MP3 and unless it's double (96kHz) or quadruple (128kHz) sampled, signal degradation is definately there. However sampling at those rates is useless for the average computer/hi-fi user as you will require specialised equipment to decode the data (typical home systems decode atmost 44/48kHz). BTW I'm reffering to sampling rate not frequency response. Monkee13 35 year old male, too much load music playing live in front of amps for many years but I could still hear 20k clear, although I hear a noise like that once in awhile just in everyday life and my wife thinks I crazy because she can't hear it. -m13 Jo Female, 20, can hear up to and including 18Hz. yl im 17 and i can hear everything Leonie I am 40 and can only hear 13,000Hz and only slence after that. I knew I had some hearing loss in my left ear but perhaps it's got worse over the year. I'll test it out again with proper speakers/headphones later. Rebecca I am 26, female, and I heard them all. belg4mit You need to be careful what you use to listen to these with. Since QT usurped my browser file associations, it was plagin back the MP3s (and tried but failed for the WAVs). Under QT I could only hear up to 15k. Saving locally and loading them in Winamp I was able to hear the 16k as well. Finally, either Winamp or the crappy SoundMax on-board card caused significant rounding errors and wrapped the 20ks back into mid-range sounds. pam I'm 25 and heard all of them except 24 and 25. I've noticed that when I am in places that they sometimes play those frequencies, and it does bother me. OTher people have no idea what I'm talking about. Tom I'm 14 and the highest i can hear is 20Khz. alex im 15, and i heard all of them... all the way to 25, though the last one made me go kinda cross eyed Dwayne Walker 41 Heard them all. Anton I'm a couple months shy of 40 and I can hear all of them. The 25 is very faint. Alka I'm pretty sure most of these people are bluffing. Almost all people can't hear past 22,000, and it is normally children that can. George How did you make these mp3, can you make it higher so I can see how high I can hear? ... omfg im 15 and i only heared till 13000;\ Rob I'm a 25 year old male I can hear all of them except for 24,000. I can hear 25,000 just fine though. Your Dad 47. I couldn't hear any of them then I realised the speakers were turned off. Turned them on and the dog ran out of the room... (OH, 12k btw) Dave Humans cannot hear above 20.5 kHz. I'm just sayin. From Wiki: Perhaps the most commonly known aspect of the psychoacoustic model is that humans cannot hear frequencies above and below certain thresholds; in fact, most humans can only hear frequencies between 20 Hz and 20.5 kHz. So-called "silent" dog whistles exploit this phenomenon by producing sounds at frequencies higher than those audible to humans but well within the range of a dog's hearing. Likewise, when compressing a digital signal, an acoustic engineer can safely assume that any frequency beyond approximately 20.5 kHz will not have any effect on the perceived sound of the finished product, and thus use a band-pass filter to cut everything outside this range. The sound can then be sampled at the standard CD sample rate of 44.1 kHz, set somewhat higher than the calculated Nyquist-Shannon rate of 41 kHz to allow for the cut-off slope of a reasonable band-pass filter. 455 30 - I can hear 24,000 (and even the 25,000 but extremely quietly) SuperAgus We are three fellow workers!! Me (32 years old) can hear every sound without problem like my boss (37 years old), but a third, can't hear anything 21KHz or 22KHz... he is 36 years old... What a surprise, don't you? I_KANT_HEAR I THINK MY SPEAKERS CAN PLAY THESE FILES NICELY.... HiVolt Don't turn up your speakers too much. I fried one of my tweeters by cranking it too much trying to hear the higher frequencies. I did, but the tweeter went up in smoke. Marty Power Whoa. I'm 48, and have been a musician my entire life - full time pro for the '70s, 80s, a bit of the 90s. I play jazz now, but I played rock/fusion when I was younger. LOUD. REALLY LOUD. I can hear 20K. Either loud doesn't damage your ears (I doubt that) or I had AMAZING hearing when I was young. (I'd bet on that.) COOL stuff, man! Rage I'm 24. I couldn't hear certain frequencies like 20K or 23K but I could hear higher ones like 24K and 25K fine. I think it must be that my speaker's ability to play certain frequencies isn't as great as with others. Darrell 18 - Heard everyone John I have documented hearing loss and was able to hear up to 24K. Btw, thanks for posting this stuff... Toby I'm pushing 30, i can hear @ 21k hz, but at 22k hz i hear the pitch for about a millisecond then it just goes away. Trifecta Age: 48. Limit: 12k. I can just barely hear 13K but only because I know it's playing; I wouldn't notice it if I wasn't listening for it. Bring on the teen-busting noise! Hey you kids, get off my lawn! Lawsy Peaked at 19,000, couldn't hear a thing after that. I'm 15 by the way. Todd 52 year old male, 13,000 is my limit. kuchimeh 16 this year, I can hear sound up to 18k, above that, I only feel something when the sound plays. I can't hear anything but I felt different when the thing is played Sean I'm 29 and I could hear all of them clear as a bell. fernando I can hear clearly up 23000 Hz, but I dón´t hear very well only the 21000Hz fernando sorry I´m 30 years old Mike Nice site. I am 45, and could hear clearly up to 17K, and just barely at 18K. I've been playing bass in bars since 1981, so I guess I'm doing OK. I would suggest fading in and fading out the samples, so there is no click. Tofer i am 23 and was a Mortormen in the USMC for 4yrs and i couldnt here anything past 20k. Zygote I can hear up to 22,000Hz and I'm 51. Shat myself though... Homertron3 Pues pa los guiris de antes decirles q si sus altavoces no pueden procesar el sonido no van a escuchar 3 leches, yo es cucho hasta el 23000, pero no se si es pq mis altavoces no llegan a mas... 23000!! Sauced 34 Year old male - 13,000Hz No wonder I never hear what my wife is saying... I swear a Dinosaur Jr show blew out at least 10% of my range Rube I'm 30 and can hear 17K clearly, 18K barely. Have always been sensitive to high frequency (monitors mostly), though, have spent significant time in front of large speakers at clubs/parties numbed enought to not feel pain ;) Carrie I can hear them all. Some even hurt my ears. I'm 29, and female. Babbalou I must be old, I can't hear a thing past 13,000 Cam 28 years old, I can hear 18k. I feel like I am hearing something at 19k, but not good enough to claim it. Anything over 19k is non existent to my ears. I am a musician, been playing guitar loud as hell for over 15 years, figured I'd be deaf by now. Juan male, 25. I hear to 20k, but i don´t hear 16k... is this bad? am I a mutant? xD my ears hate me now David Age 43 and can hear up to 21,000 Hz jill Interesting. I tried this on my Dell laptop with and without headphones. Couldn't hear above 16 without headphones. With headphones I could hear 18 and barely 19 but not 17. Then I tried it with my students today and they all heard 17 loud and clear. I couldn't. Player was Quicktime. I changed the player to Media Player and I could hear ALL of them with the volume at 50% with the exception of 21 and higher. mongooz i used headphones, not my computer speakers, and i can very clearly hear 25,000 hz....it would be cool to have the test go up to 30K or so....just to see if i can hear that. mongooz oh, yeah, by the way, i'm 50. Amit Arora I am 27. I can hear @ 18,000 faintly. But not 19,000 onwards. Greg 27 year old male, and I could hear them all. 25k was faint, but it was there. 24k gave me a headache. jill Interesting.

Eh... not so much Here's a NY TIMES story about the ringtone: http://www.nytimes.com/2006/06/12/technology/12ring.html?ex=1307 764800&en=2a80d150770df0df&ei=5090&partner=rssuserland&emc=rss Best part is the graphic that shows the normal frequency ranges audible to various age groups. Looks like, at 17,000, I'm still better than most of my fellow 30-somethings! Deus I'm 18 years old and I can hear the 25000HZ one. Then again most people probably can't hear right because their speakers/earphones doesn't allow them to. I'm using ATH-M30 - audio-technica. David I'd hazard to say that a lot of people that cut out over 15 have cheap headphones/speakers, as this is where a lot of the lower priced items cut off (even my harman/kardon speakers cut out at 15kHz). I know I can hear over that, as I can hear 16kHz in my headphones, though they are only rated to 15. Have to find some rated better to see what I can really hear. I'm 35 40 year old male, highest ones hurt, but can hear up to 25k with quicktime myself I'm 29, and I can hear ALL except 24KHz :? 23KHz and 25KHz are audible to me... Bobak 26 years old, could clearly hear 18kHz, barely, barely differentiate 19kHz, nothing past that. Bryce B. I am 25 years old, and am deaf in my left ear. I do not know if my right ear is heightened after 10 year of having only one ear, but I am able to hear all of these frequencies with my headphones at a volume level of 3 of 100 on the Windows Media player except 24,000. I can hear 25,000 just fine but the 24,000 tone is silent. All the others are almost unbearable. Very cool site thanks for creating it! Alex Hi all, I'm 17 and I can clearly hear 25000Hz. I've always had great hearing. heather I played these with my kids in the room. I was quite sure that it was just my computer or speakers because I could not hear any of them above 14kHz - but when I played the others with the kids around they screamed.. TURN OF THAT NOISE. All the way up to 22 :-) Guess my hearing isn't so great.. I"m only 31 Marina Brown Heard sound from all of them except that the higher frequencies seemed lower than the ones at 17-18K. I turned up the volume for the top one and both me and my companion SCREAMED. The sound was horrible. We are 40 and 50. We will check the sounds out with better equipment. 40 year old male, highest ones hurt, but can hear up to 25k with quicktime Marina Brown Heard sound from all of them except that the higher frequencies seemed lower than the ones at 17-18K.

Lordka Tengo 24 y logre escuchar hasta el 25 excepto el 24 que no se por que no se escucho. Mikko Either there's something wrong with the 19000 and 20000Hz sample or then it's just my sound equipment. I can barely hear 16000Hz, nothing higher than that, except that both 19k and 20k play a really loud buzz. Doesn't matter if I use speakers or my headphones. Craig Sheppard Hi -for those of you who are unable to hear the tones in the middle, the problem is probably your soundcard. This is extremely important. In order to accurately follow this test, you MUST have a soundcard capable of 96k DA conversion. Also - speakers that are flat to at least 25k are absolutely required (most are not). There is a phenomenon in digital audio called Aliasing which mirror-image maps tones back down once they cross a certain threshold (the Nyquist frequency). The Nyquist frequency is exactly half the sample-rate, so if your soundcard is down-sampling the 96k files, then it is either a) creating the 'reflected' (Aliased) sound (if the down-sampling algorithm is poor) or b) filtering out sounds above the Nyquist frequency before the down-sample (if your downsampling algorithm is good). If your soundcard only outputs 44.1kHz, then the HIGHEST sound you will be able to hear under PERFECT conditions is the 22000Hz file (assuming your soundcard has excellent convertors, and that your amplifier/monitor combination is very high quality). Many soundcards are MUCH poorer, which really negates the value of this test. This is why it is so important to have professional quality testing equipment - there are many people now coming away from this website either thinking that they have chronic hearing loss, or that they have superhuman hearing abilities. One final note - in order to test hearing, the intensity of the sounds must also be controlled. I may not be able to hear 20,000Hz at all at 30dB, but it's painfully loud at 100dB. In order for this test to work, the users' monitoring system should be calibrated, and the tones played back at a reference level. An Audiologist would not test any intensity for these tones, but would instead test the THRESHOLD for each tone - ie the lowest volume level at which you can hear each frequency. Unfortunately when testing threshold, you need a very quiet monitoring environment, ie an anechoic chamber or isolation booth. Anyway - not intending to trash the article, because I think it's good to interest/educate people on hearing loss, and I wish these tools were available to everyone without having to pay money to see an audiologist, but at the same time, sometimes bad data is worse than no data :) If you have any questions, feel free to drop me a line: craigsheppard@mac.com Jimmy Not a bad way to test your hearing without going to the doctors i hit the 18,000 Hz crush just turned 20 and i can hear up to 19hz 20 hurts. i dont think its about age just about how well you can hear Craig Sheppard One other note about the original article. I think it is extremely irresponsible for the business owners to be employing a system like the mosquito - this is basically noise pollution (albeit, pollution that only a certain targeted portion of the population can hear), and if it's loud enough, it could cause permanent hearing loss for anyone exposed to it for a length of time (which could be as little as 1 minute, depending on how loud the sound is). -Craig alek hi, my head is boom! with the waves of 20.000 hahha, someone have wave shorts?? i would like to ear down extreme waves.. greetings famine i could hear everything up to and including 22000. im 26. me i am 15 and i can hear up to 25000k it kills my head Scott Simmons Age 37: I was able to hear clearly up to 13K, could just make out 14K, nothing higher. My 11-year-old son was able to hear up to 18K, so it definitely wasn't my speakers. Amigajoe http://www.softpile.com/Education/Mathematics/Review_21743_index.html -This is a link to a software frequency generator that produces pure tones for a given freq. Much more accurate than the samples. Turns out my hearing isn't as good as I thought! ;-) paradox i found this very interesting. my limit is between 18 and 19,000Hz. does this mean im a 28 yr old kid? p.s. i cannot stand loud music close to my ear, ie headphones. one love Nicola 25, heard all but 24 and 25. Phew, some of those were VERY irritating. cbass 21 and can hear all the way up to 25000 kiwnix I hear the 23000 Hz at most, i can't heare 24000, so i do a test, the most i can heare is this: (ecasound is a program for linux), with this you generate a tone of 23999 Hz. ecasound -f:32,1,48000 -i null -o alsa -b:1024 -el:sine_fcac,23999,1 mark currently 18 and can only hear up to 16,000 but none of them annoy me. I never listen to music loud though and everyone in my family is fairly sensitive to loud noises. My ten year old got got up to 19,000. Results are find of scary. Dave Several of my colleagues, around 18 of them, tried the tones. some people could hear upto 20k and some couldn't hear anything above 13k. One thing is clear that there was absolutely no correlation with age. Some of our younger colleagues in 20s and early 30s who dont listen to loud music all the time couldn't hear higher picthes wheras some of the older people (mid 40s and above) could hear all the way upto 20k. It is true that as you get older the hearing goes down. But the reverse logic does not hold true. Hearing ability does not indicate age of a person. purify hum, When i first tried it on my comp and quicktime, i only got to 17khz. But on my girlfriends computer at around the same volume, and much worse speakers, and musicmatch i could hear 20khz. ScArNia I can hear all the samples with no problem. Is it a record? I always think that i can hear rare sounds because usually i can detect where is a electronic hardware because i hear a sound from this when other people cannot hear it ron im 21 and i can hear 24 000 just fine but 25 000 is really difficult to hear, but i can barely hear it if i really try to listen. Larry i'm 19 and i can clearly hear it all the way up. Juanse I'm 18 and I can JUST BARELY hear the sound @19000 Juanma i'm 26 and i can hear 25k like one whisper, 40 year old male, highest ones hurt, but can hear up to 25k with quicktime Moon 18-19, can distinguish 25.000 over the undertone rising from my somewhat poor headphones. jr I'm 33 and my head just exploded. Thanks a lot. Laura deGrey We, Marina Brown and I, tried them again on better equipment. OWWWWW!!!! We could both hear clearly up to 22000, although 19000 seemed to be harmonics rather than the pure tone. Our cats went berserk! The higher tones made us feel ill. Definately keeping a link to this site. ;) Lepu I'm 28 and can barely hear the sound @16000. Roberto Tengo 28 años y consigo escuchar hasta 20000 airship I'm 54 and 14,000 is my limit with this test. I always used earplugs back when I worked in a factory, and never listen to music too loudly. Once upon a time, I could easily hear 20,000. I suspect part of the problem is my cheap speakers, but I also have noticed the highs going out and some tintinitus the past couple of years. DutchRub I'm not old, I'm 37! From Monty Python's ~The Search for the Holy Grail~ 17,000 is clear but 18,000 or higher is gone. Eddie I'm 22. I hear low between 16khz and 20khz. At 18khz I hear an oscillation. From 21khz to 25khz, it let me explode my head! Why don't you put higher frequency, so we can try them too! Julie I'm 44 and can hear them clearly up to and including 1800. Lzygenius I would love to do this for the higher tones but all of the speakers and headphones I have top out around 19000hz. My main desktop speakers only go to 15000 and my laptop will go to 18000 but my best headphones headphones go to 19000 and both me and my 12-year-old sister heard it perfectly. Hope that helps some people out wjo are topping out early. Kajikit Interesting. I'm 35 and I can clearly hear(feel?) the computer monitor whining and tvs... when I listened to the samples I could hear up to 16000 clear as a bell, and then nothing. I can't hear the first sample either, until it's slowed down. Kajikit PS. We have three cats and they totally ignored ALL the sounds... so either they're all deaf or it just doesn't bother them! Katie I'm 16 and I could hear 20,000 Cat I can hear until 20000HZ quite clearly and I'm a 17 years old girl. Big John I'm 60. Couldn't hear anything in any of the samples. I couldn't even hear the slowed down sample... Guns of Vet Nam, and Rock and Roll! John Milly I can hear all of them, and I'm 27. Not a surprise though since I could hear dog whistles as a child. Rick 25 year old male - can hear 20k quite clearly. Anything above is outside the range of my headphones. My father - deaf as a post couldn't hear the 10 even. Chiro Boy I am 43 and I could hear up to 20,000 (barely) - definitely 17,000 was clear and so was 18,000 (somewhat). Like the others said, it has alot to do with your system and it's capabilities. grunghd I can hear all of them still, even with the last few as WAVs. Chris N. Just turned 37, M, I could hear all of them except the 24,000 but I can hear 25000. Although, I can not hear the tone in sample 1.. The one with the chatter in the background. Andrew I'm a 27 year old male and I can hear all but 23,000Hz 24,000Hz 25,000Hz Sarah and Dylan we are 23 and 24 and we could both hear up to 21,000 just fine. Brett I'm 27 and am wondering why the kids just don't put their phones on vibrate. Dani Is it normal than I can hear from 10000 to 17000 and from 21000 to 25000, but not from 18000 to 20000? Dani that*, sorry ;) Christopher Coleman For what it's worth, most of you don't have speakers or headphones that can produce more than 20 KHz. You may get something, but it's really unlikely that you're getting the correct sound. You might be getting a slightly distorted version due to your speakers attempting to do their best. A lot of speakers will tell you the frequency response on the back. I have a set of M-Audio Studio Pro 4 speakers, and they do up to 20 KHz. I can make that out just barely. I kind of wish I had dog around to test out the higher frequencies. Toni I heard all the samples except 24000 I'm 28 years old. Alfredo Mine reached 19,000 I'm 33 but having being an unprotected-ear drummer for more than 5 years... jorge PLEASE let me know... do all of these examples should sound the same? I mean, above 19,000HZ all I hear is kind of a static noise. Is this correct or should I hear a crt monitor-like sound? (that is the one I heard at 19,000HZ and below) jorge PLEASE let me know... do all of these examples should sound the same? I mean, above 19,000HZ all I hear is kind of a static noise.

Very interesting. I'll have to have my husband try it. He is 28 and is suffering from significant hearing loss (the ENT says he has the ear of a 70 year old). Jonathan Hey I'm 18 I can hear up to 23,000 but it is really faint, just emough to irritate my ears a bit. After that is pure silence. aaron I am a 14 year old male and can clearly hear all of them. Riley I'm 13 years old, male, and I can hear 20 clearly. When I turn my speakers all the way up I can hear every one. Trevor I'm 21 and I couldn't hear anything out of any of the files.. i think you're all full of crap. Trevor oh nevermind. my volume was off. Andrew 42 year old rock musician. L: 15K R: 12K I've been wearing earplugs continuously since the age of 30 to keep what I've got left. A stage accident at 16 in my right ear (over-volume for 10 seconds) is what caused my losses there. brendan i'm 60 and can't really hear anything above 14k, although I'm aware enough at both 14 and 15 to be uncomfortable. but if i didn't know why, i would not be able to say. Mike I'm almost 21 and I can hear up to around 20k-21k or so. I have listened to loud stereos for a few years now and have yet to notice the effects of this on the range of sound I can hear. zoe im almost 16 and the 25,000 is clear as a bell. i also listen to headphones and loud stereos and i am starting to not believe that they alter hearing. Jacques I'm 51, and 11000 was the limit. I did play in loud rock bands, weekly from age 15 to 32. That was back in the days when the amps were the sound projection, not the PA. DOH... Allan 39 and male. I can hear the headache-inducing 19K clearly, but silence at 20K. ******************************** If I encountered that 16K anti-loitering device in public I'd hear it perfectly for exactly as long as it took for me to find it and smash it with a brick. Thurgood My six yr old son can hear up to 21000 but I can only hear up to 18,000 at 35 yrs old. JCx Age 68, heard nathing at any frequence with $5,000 ITE Phonak Hearing aides and Boze Quiet Comfort Headphones!!! Emily 19 female. I heard it up to 25 000 woot. I'm 20 and can hear up 19 clearly, but everything after that left this horrible ringing in my ears that pulsated and just kind of lingered. Whoever decides installs this device is going to loose a lot of business... Annabelle I can hear them all loud n clear....most likely because im in my 20's rob i'm 31 and i could hear 20K. also, my dog hates you. she can hear 25k. Alex 13, and I could hear up to 21. My ears are still ringing Taylor I am 16, and i can BARELY hear the 17,ooo frequency. thats shitty!!! Alan interesante, escucho casi todo menos las frecuencias de 24000hzy 25000hz Amber I'm 29 and can hear all of them loud and clear. In fact, I have a bit of a headache now and wish I hadn't tested myself :( David I'm 38 and could hear tones up to 22000 Hz. Guess all that loud music as a teen didn't affect me as badly as I thought James I could hear up to 24kHz and I am a 29 y/o male. This is sort of odd as I alway had issues understanding speach, so I always though I had hearing issues. Erin I'm 18 and could hear up to 20K. Anything above that made me pretty uncomfortable Telepuz I'm 39 years old male. I can hear up to 13K. Michael I'm 38 and can hear up to 24k. Weird, since I have trouble following conversations in loud rooms. James Awww my cat meows at 25k and I cant hear a thing Seth I'm 21 and I can hear all of them - all the way up to 25000 Hz..give me 26000 lol :) Eric Im 15, hmm... I heard all the way up to 25K without a problem. Brian I'm 21. I could hear up to 22k. For others, if you score was on the low side, there's hope, it may not be your ears, but your speakers. I could hear 21k and 22k through good headphones but through a mediocore set of desktop speakers, I could only hear up to 19k. Not hearing the tones may be a result of listening through speakers that can't replicate them. Eric Hz I Mean, I have no Idea were K came from. Daemon Behr I'm 27 and I can hear them all. You shold put some higher ranges aswell. ----- im 16, and i toped out at 19k. thought this was intresting so i thought i would try my own tests, so i got my dog and put him in front of the computer, first i started low and the lowest seemed to bother him the most, but not to the point of any real stress. as i moved my way up i noticed that his reaction lessened as it got higher until i reach the 18k-20k where he again showed signs of discomfort. finally i took it all the way to the top in which his ears fell back, but he didnt seemed as bothered as the 10k. what this means, i dont know, but i bet you someone could use this tech, wether is be for a greater good, or a new form of sobliminal advertisement! Sarah I'm a 21 year old female and I could clearly hear ringing up to 23,000 Hz (I'm not sure if I should be glad about that *ouch*). I hear somthing on the 24,000 & 25,000 Hz tones, but it's more like white noise than ringing. This was interesting. Thanks for posting them. ^_^ Tom I could hear up to 21,000 Hz but for de last two i had to pick the volume up. Matthew. Cs I'm 21, and i could hear between 19000 and 20000, anybody thinks that the speakers had some influence. Rosalind Yeah, I'm 23 and I could hear them all too. It'll be interesting to see where my hearing drops out. A friend of mine can hear high pitch cat cries that I couldn't even hear. It'll also be interesting to see where HIS hearing drops out. sam I'm 24 and I can hear it at 13,000 but not at 14,000. Rog Is this for real? I'm 58 and I can easily hear every tone on that list. I'm also a musician and expected my ears to be shot. 25kHz is very annoying. Eric I heard them all the way up to 23kHz. My head still hurts > Shadowy 25 and I heard all until 15kHz. Gah, now I feel old. David 38 year old male and can hear up to 15khz. Not surprised tho, years of rock gigs and hard house events have most likely done some damage. Iain I am 49 and can hear 14K clearly, 15K to around 17K less clearly and 18k not at all. I am a musician. I spent 3 years as a professional transcriber and probably listened to a lot of music too loud in headphones. David I'm 19 and I couldn't hear anything past 17,000. I work on an airbase and there are constantly jets taking off.. unfortunately, I do not always have the opportunity to wear ear plugs or some other form of ear protection. I try to plug my ears at least with my hands when I can, but sometimes I am also not afforded that opportunity. The jets were cool at first but... I am starting to not like them so much. charon btw. do your soundcards and headphones reproduce the hi-freq sound correctly? bob i am 31 years old, been djing a lot these last 5 years and i can only hear until 17000 hz. I did a test last year and they say i'm slowly becoming deaf on my right ear. So now I use earprotections when I go out. Daniel I can hear every soundfiles. Am I a superstar now? :-) Jan I figured that some software produces false sounds. First time, using Quicktime Browser-Plugin, i (23 years old) could hear easily up to 24 kHz... although some files did sound very loud and "weird", not just a high tone like it's supposed to be. Anyway, now it works... no strange loud tones but just high pitch beeps that turn lower as frequency rises. --> don't trust this if you clearly hear loud noise up to 24 kHz and try other software! Cram Snave I can hear all sound but 17000 don't, this is wear, but true, I test the sound with Normal speakers, 7.1 speakers and IBM HEADSETS, and 17000 are nothing for my, but the rest I can hear it all. 25 years old. Jan forgot to say: now that it works, i can only hear up to 16 kHz. Daniel My threshold is at 14000 and I'm a 30 yr old male. I probably killed part of my hearing playing loud music, and riding around on motorcycles with loud exhausts (terrible for your hearing). JC äh Naja I dont know if its normal but i could hear even the 25 000. Realy silent but i could clearly hear a tone. I am 30. Is it possibel? Dears JC Rocco 31 years old - 23,000 Hz Hans Holbrink You guys realize that anything over 20kHz also tests your audio equipment? It's quite possible that 21kHz introduces artifacts that you perceive because your monitors are at their limit, not 21kHz per se. ME 26 years old, 20.000 Lorenz I'm 15 an I hear 25Hz clearly, do you have something higher for me? xD I know, it's a bit strange, bit somethimes I even hear bats. :P Matthew I'm 19, and I can't hear anything above 11,000 Hz. I think that means my ears are in definite trouble. Uh-oh... undefined are you guys shure that your acoustics can play above 20000Hz? my speakers for example have such a range 20-20000Hz. good luck .) Raimund Hi I'm Raimund, a 15 year old. I can hear the sound till 23000 but I think over 18000 the sound gets lower not higher Jan C Hello, I would like to know what volume control factors into this test. Should the speaker volume be set very low to get an accurate score? Regards, Jan C Jan C Hello, I would like to know what volume control factors into this test. Should the speaker volume be set very low to get an accurate score? Regards, Jan C Jules What the hell? I am 23, could hear anything from 10 to 16, but NOT 17 to 25!? Why can't I hear the low noise?? Does that mean anything? Klaus I am 58, male and can hear up to 15.000 Hz. Lorenz Jules. It's diferent from people to people, I can hear them all. It's normal for your age. But's abnormal for my age to hear them all (15). tom I'm 23 I regularely visit techno parties, but at normal volume I can hear up to 21 000 Hz and if i turn volume up I can hear it up to 25 000 Hz. tom Thorsten Male, 30J I could hear up to 16 kHz. When I reale concentrated on hearing, i seemed to hear the 17 kHz. Bernd Shit ! I´m 36, male and i hear up only to 16.000 Hz !!! Andrew Hi, I´m 34 and can hear clearly until 21,000 Hz. Luckily I never tortured my ears with loud music, but I will visit this site from time to time to see (or hear) how things change :-) Dani 28, Spanish and smoker (it affects), and i can hear all except the range between 18000, and 22000... strange no? ishwar Up to 13.000 loud and strong, 14.000 much weaker, with 15.000 the high pitches are gone. I'm 42, heard never loud music, but worked for some years hitting with an hydraulic hammer on stealpipes (not every day). But I was always wearing ear protection. Danny I'm 27 and I cold hear the 15,000. I like to listen music in my car loud. ;-) unicatum i am 29, just could here until 15.000. heard a lot of loud music, thats maybe the reason Sergio I'm 23 and I can hear the 20000 one. No more than that though. Joe I+m 52 an can hear each ear separatly till 25.000. Ivsn i can hit 25000khz.. at highest it sounded like air.. high pitch air. Can standard pair of speakers reach high freq? I have a THX set so i guess it could , how about a normal speaker setup?? Penandwise I was able to hear up to 18000 clearly with normal db. Once I turned up the db I could hear all of them. herbstwerk i'm 26 and can hear clearly up to 23k, at 24k i might just hear it because i know it's there and at 25k... nothing. and i am ruining my ears with loud music all the time - at least i tought so ;) Jay 17 - Heard them all Steve Most MP3s are sampled at 44.1 kHz. At this rate, the maximum frequency you could record is 22 kHz. Most humans cannot hear frequencies above 20 kHz. Most adults can't here frequencies above 14 kHz. Holly 43, and I could hear all of them at full volume on my speakers - some were fainter than others, and it seems that at tones between 15 and 20 I need more volume than below and above that range, so I think maybe the flaw is in the samples. Not sure - this isn't exactly as sophisticated as a standard hearing test would be. ;) But it's entertaining! (I had more difficulty with 13 and 15 than with 14 at the same volume, if that's indicative of anything.) Holly P.S. Someone mentioned they can hear bats. That's not so odd. I can hear mosquitos whining. I assumed everyone could, but apparently not... Steve Most MP3s are sampled at 44.1 kHz. At this rate, the maximum frequency you could record is 22 kHz. Most humans cannot hear frequencies above 20 kHz. Most adults can't here frequencies above 14 kHz. AnthonyG 26 years old, could hear 18,000 but not the 19,000. PhilW Age 61, male. I can hear up to and including 20,000 Hz clearly. Nothing at 21KHz and above. Oli 35 hear 16 .. played bass hole life long searching for a new band mail: bassist-oli@web.de. write loud, that i can understand it :-D Henry-Ch I'm 32. Can hear up to 16kHz. Interesting! Nice site! Tom Hah... Did the guy ever think the kids might have blown their ear drums with all the load music they listen to? I'm a teenager and I can hear up to about 15,000Hz, and I can't hear the noise. harris the 18,19 and 20k sound bits dont sound right, they arent high pitched like the other sound files but rather.....a buzz, i think it might be an error in the actual files, not my hearing. ps, im a 17 yr old Cox1e Surely it will depend on the quality of speakers/headphones. by the way ' it made me feel wierd'! aers hear everything... just a feeling Gabriel I could hear from 10000 Hz to 250000 Hz! all the tones.. but my mon (she is 49) couldnt hear the 11000 Hz! =S.. only that one Phred I'm 41 and can hear up through 21kHz. That's through computer speakers with an aquarium running in the background. Miss Sara 25 year old female. 18,000. Paul 24, Male, England I'm not sure exactly what is going on here... I can hear the 18 19 and 20k samples absolutely perfectly. However the 18k one is the highest pitched noise by far. Followed by the 19, then 20. Either my hearing is seriously messed up or you've messed the samples up. Cant get anything around 21k, not sure winamp is actually making a noise but that might be where mine is giving out :) John I can hear the first one, but it isn't unpleasant. I've always had trouble sleeping with electronics noises in the background (like a muted TV with no signal, or a monitor that's on but not connected), and this reminds me a lot of them. I know it's much fainter now than it was when I was younger. I lose the sound more or less completely at 17k and above Interesting experiment steffen I´m a 25 year old male and even if I was in discos very often, I can hear the 24k (very quietly)! Nice testing! thx 49'er Can't hear above 13000, but anyway, i hear whistles in my head all the time, so I don't know if I don't hear or just can't discern the sound wozzer i can hear em all and im 24, and i rock my ears to death.. ow Justin Any way you can post the other files in true wave format aswell i want thoes anoing things on my phone but i can only have WAV,AMR, and MIDI files on my phone. im 29 i hear the 18 nothing after that but may be my speakers output according to my last audiogram i should hear up into 19 range. EsMaster i`m 19 and heard both of them, but sample 2 was much more clear to hear Alex I am 18 years old and play in a punkrock band, so maybe my ears are a bit wasted but I can hear it up to 17K. Anything above is silence to me. MP I have tinitis and high frequncy hearing loss (genetic) and I'm 49. I only heard up to 14000. Only heard background noise on Sample one and nothing on sample two. Djarne I can hear all the frequencies except the 24,000 Khz. Yet I can not hear the pulse on sample1 file. On on the one slowed down a tad...I can. Explain that... I am 41 Years old.... tom i can hear up to the 23 one, and im 14, i also torture my ears with loud music =-) Justin Any way you can post the other files in true wave format aswell i want thoes anoing things on my phone but i can only have WAV,AMR, and MIDI files on my phone. im 29 i hear the 18 nothing after that but may be my speakers output according to my last audiogram i should hear up into 19 range. Leon D I could hear upto 15000, but 16000 and 17000 can hear small clicks thats it...whereas I could hear both the samples quite clearly....what does all this prove? Dani I can listen 20k very clear, but nothing up of this. Joshua C I'm 24, and I'm listening to these samples on a pair of $20, so I don't know what their frequency range is, but I'd guess they can do 20khz because I think that's pretty normal. I could hear everything up to 17khz, but the 18khz and above sounded completely silent. CHeater Joshua, I am 24 too and 17k is the end my range. Let a 6-year old test your $20s. He will hear the 20k tone. Joshua C When I said "$20" above, I meant "$20 headphones" William William 53, I can hear up to 14K and then nothing. Better so :-) Lily I can hear up to 22khZ, but not above that. (I'm 25) Chris I am 39 and could hear everything up to and including the 20KHz sample in WinAmp until I turned off the equalizer. With the equilizer off, the highest I could hear was 14KHz. Jane In a parking garage in Australia, they are piping in Barry Manilow to get rid of the loitering kids. But that's cruel to adults too! Friedo I think I have the honour of being the oldest participant. At 59 I think I can make something out at 12k but obviously nothing beyond that. The disability is however offset by cheap car insurance. Jess I'm 27, and I can hear everything up to 20 kHz very clearly. Everything over gives me that fingers on the chalkboard feeling, but I'm not sure if I hear it or not. A2B I'm 23, male and hearing @ 21000 hz. RUB i can hear 24000, barely.... im 17 Brian I can hear 19 with the volume all the way, nothing for 20. I'm 23. WIDSM! John I can only hear up to 15,000...but I work in a nightclub as a DJ....so my hearing in noticably shot. Desirae I can hear all of them and im 16. Good thing I know sign-language! Cuz there aint much to hear after this Brian i could hear up to 22000, skipping 21000. im 16 and have worked a long time in housing contracting with my dad, might explain it. now, TVs are repellent in my school, almost everyone hears those things! some worse than others... old TVs are the worst! Keith 35 yrs old. I can hear 19K, but cannot hear 20K. My computer's sound card seems to go wacky with 21K and above. I can hear something but it is obviously not 21K. Andrew I'm just shy of 49. I could only hear up to 10K when played on Windows Media Player, but I could clearly hear up to 20K when played on WinAmp. After that the .wav files for 21K to 25K made WinAmp freak out. Geoff Mid-30s; I've played in loud bands since age 15 or so, and have some damage to my right ear from a physical injury as a young adult. I can "hear" everything up to 22K, and "feel" the samples up to 25K, although I had to put on good headphones to make sure I was getting the 24 and 25K samples. (Although my project studio monitors should handle the high frequencies, I didn't want to crank the amps, and the room may be killing them anyway). I was a kid with asthma, though; I think I once read there's some statistical correlation between asthmatic kids and high hearing ceilings. Certainly I've been more annoyed by televisions, flourescent lights, dog whistles, and the like than most people I know. eddie I am 19 and was able to hear all of them. Jason this might be nit-picking, but the study seems flawed, as not everyone's computer speakers will be able to reproduce sounds as high as 25kHz. Loren 40 here, I can only hear the 10,000, nothing beyond that. Some people on here are reporting that they lose it at some point and then hear sounds above that point--I suspect it's not being handled correctly by their systems. Lilly I can hear all of them Wurst09 As posted before by undefined: "are you guys shure that your acoustics can play above 20000Hz? my speakers for example have such a range 20-20000Hz. good luck" I can hear 20000 quite well but when it comes to 21000 i dont hear a thing... At least a comment about the nomal speakers in the text would be nice... uknown I am 17 and 19,000Hz was the best I could do, and thats with blasted music and concerts more often than not. looks like I'll be deaf when im older. Uknown "I can hear 19K, but cannot hear 20K. My computer's sound card seems to go wacky with 21K and above. I can hear something but it is obviously not 21K." Same here, or at least I think... I hear clicking noises.. Im hoping its not my headphones cause they weren't cheap and are supposed to be excellent quality. Domen I'm 20 and I can hear all of them. Brian Im 14 and i can hear up to 19000hz Chris I'm 22 and I can hear all of them, too. Gizmo Doc I am a physcian and also a gadget geek. Just want to warn everyone that this is likely not a valid test of your hearing so don't fret about premature degeneation of your senses. Most of you are using audio cards and more importantly speakers, that can not posisbly generate the higher frequencies. I am in my mid 50s and car easily hear the 22 Hz tones as I have an audiophile system with Creative XFi Sound Card, and supertweeters that can generate sounds to 100 Hz. Slackenoff I'll be turnin' 50 in November. Just barely at 21KHz and nothing from 22KHz on. Arturo & my daugther Michelle Age: 32 & 3 years old Limit : 25 Khz both and I ( Arturo) can hear the monitor sound ( TV with no signal is worse than monitor ) commentor just needed to let u no BANDIWIDTH FOR THIS PAGE HAS BEEN EXCEEDED as of 7:26PM EST USA NJ merry BANDWIDTH FOR THIS PAGE HAS BEEN EXCEEDED Flash Hearing Test I've made a flash version inspired by this article (not using your sound files) here: http://www.jimmyr.com/blog/Hearing_Loss_test_Human_Frequency_Range_164_2006.php Jimmy Thanks for posting it on top! I've added a zip file with the .wavs I made too. The pitches were generated with goldwave f(x) expression evaluator using a simple sine function. Wally OH the club years..tried the flash test, only to 10K :( Dont know about this site, bandwith issues. Stuart Buck I could hear everything, including the 25,000 tone. I'm 32. Any chance of extending the sound files? Maybe up to 30,000? I'm curious to know where my hearing drops off. Butch I could hear up to 16k with normal speaker settings after that I had to set it to Key +2 to hear up to 24k but 25k I had to have it all the way up to Key +4 Butch I am 19 I forget to put my age earlier Batas Im 28, i can hear 19k with normal speaker settings. More louder more k. ashmeed 24 yrs i did not hear the 23khz and 24khz,, but they were painfull Josh Im 14 and i could hear up to 25,000 sam lofley eyah i can only hear up to around 19 past that its just nothing to me oh and im 16 takshaka Wop !!! I Just can hear 10.000 & 11.000 Hz, Too Bad !! Scott Robert - I heard the background laughter in sample 1, too. If anyone's concerned about actual hearing loss, have your hearing checked professionally by an audiologist. Good idea to have a check every ten years or so, sooner if you notice you're missing words/sounds. And no, I'm not an audiologist, lol. Gail I am 48 and I can hear every one except the 24000. BUT, in order to hear the later ones, I have to have the volume on max. Sambiena Apparently the teen buzz is also been dubbed as the MOSQUITONE in the US and some parts of europe. I found this website, but you can´t download anything, simply listen to 4 versions. http://www.mosquitone.net Has anyone successfully used it in class? Jeremiah I can hear all of them excpet for 22 and 25... 23 and 24 are clear tho... wierd...! Desmond I am 25 and I could only hear 11,000 :( Matthew I am 24 and could only hear up to 16,000. There is a slight ringing in my head whenever it goes higher. Oh well I guess thats what Iraq and the Marine Corps will do to hearing. :-) Rosey I am 7 and I can only hear 17 and lower. My dad can hear 12 and lower. He is 40. Katie I'm 16 and I could hear 17 and lower. My mum watched me as I kept increasing the frequency. She was wondering why I suddenly balked at 15000 Hz. I can't take it, it's like putting a sewing needle into my brain. Larry Actually heard clearly up to 20,000, then absolutely nothing. I'm 55 and have played music in rock bands since the age of 14 (and still do now, except a bit lower, rockin' out—really—in church), usually playing pretty loud thru the years, but never quite heavy metal. (BTW, I do have a *very* slight high ringing all the time, but I never notice it unless I listen for it. Perhaps *everyone* has this to some extent. Comments?) Whatever, I was somewhat worried, but now I'm very happy because I match what two 17-yr. olds sitting here with me are hearing. Beatup I heard the sound at 22000 I'm 32 male. odd thing is it dropped out in the 15 - 21 range.Earsplitting at 22 though. Sterling Camden I'm male, 46, and I can just barely hear 15,000. Not 16,000 though. Osvaldo Lopez I'm 38, and I've been diagnosed with loss in the left ear. Shure enough I can hear 20,000 on the righ, 15,000 on the left. My daughter, 11, hears up to 22,000. ahh i am 20 and cant hear anything above 17! Brenda My son had me try this and I could only hear up to 12k. I am a 48 yr old female. he could hear to 16k but barely. romain i'me 16 and i can hardly hear the 21 Shelle i am 15 and i can hear 19 Rachel I am 16 and i can hear all the way up to 23. josh my school had devices to get rid of bugs that emitted a high frequency noise. the students could hear it but the teachers couldnt. i took a while of kids complaining of headaches for them to descover the problem. MANTIS 32, could hear to 17K but feel higher, I've stopped as I now feel quite sick from the higher freqs. I can often hear the TV(Standby Mode), monitors, transformers etc that are really irritating when you're trying to sleep. But I think in the day time I just block them out. This seems to have re-awoken my awareness and I can't stop hearing all the buzzes around me, I work surrounded by electronic kit. :o( It would be interesting to see the same thing done but opposite spectrum, LOW freqs, apparently if you get low enough and loud enough you can make people vomit and trigger the paralysis fear response. They've investigated it for riot crowd control, bit messy I think, need to follow up with the water cannon afterwards. felix heard it all the way to 22- I'm 18 years old. Peaches Damn.....I'm 52 and all I can hear is to 12,000....I'm deaf!! chuck norris i could hear them all. im 18 Megan 18- Heard all but last 2 were real faint Charles This is really awesome! I couldn't believe it at first but me and my cousins tested it out, i'm about 3-5 years older than all of them so my threshold was at 15, but my cousins who are 13-18 years old can hear up to 18.... I guess my parents are right, I AM going Deaf! haha alyssa im 13 and oh god that hurt my ears what kind of torchure is that?!?! well if they use that to get rid of kids it would definately work on me! Aaron i can hear up to 1800hz clearly and 1900hz very softly Richard I'm 55 and i can hear the 15,000 hz – and that's it! But maybe it's nice NOT to hear EVERYTHING anymore in my age – isn't it? Greeting from Germany: Richard Dr Hilary Rhodes I am 58 and I can hear the 15,000 hz with headphones under noisy ambient conditions. I used to have very sensitive hearing, but driving to work 4 days a week, 50 km each way for 8 years in a VW Beetle somehow must have knocked the top off my hearing. I tried the teen ringtone on my poor students today, and they really did hear it, as it was a blind experiment, and I put it on the computer through cheap speakers, and did not let them know I was going to do this. I played it a couple of times and watched their reactions. One fellow with his back to me started rubbing his ear. I did it again and got the same reaction and another chap on my left then said to me 'What is that irritating noise?' and I owned up to my little experiment. I can hear the original teen ringtone with my iPod speakers, but in no other way. It is awful. io I could hear the 17.000Hz File. I heard it almost clear. But at 18.000 I cannot hear it. AyamiWired I can hear them all, but some has make me feel sick. raul fenero I'm 64 years old and i can hear all of them perfectly. Nathaniel Wapcaplet (Snr) I'm 82, you know. Everybody mumbles. I can't hear a thing unless you mutter about me when my backs turned. Damn kids... cp im 26 and i can hear all of them up to 24k hz some of them really hurt Martin Hi, I am an 44 old male an can hear up to 15.000, my girlfriend can hear 17.000 and she is 46.... Futurama 17 and I can hear the 22,000HZ fine but I can't hear the 23,000 at all... Achim Hi, im 25 and can hear up to 21.000 Hz... Maldavius 26 years old and I can hear the 22.000 fine but anything more and it just makes me feel nauseus but I dont really hear anything. art I'm 58... I could hear 12k but not 13k. 11 was painful. Interesting sampling. [art] lost I'm 30 , I could hear upto 16000 and also 20000. I use a cell phone boom mic as my headset. Derek Amplifier and speakers/headphones a big factor! A lot of PC audio gear is second rate with a freq response of 50Hz-18kHz max. So people, don't be too worried! :-) HenryR With OK speakers I could hear 14kHz but only faintly hear 15kHz. with a good headset I could hear the 15kHz but not 16 kHz. I'm 50. Sure glad I wore earplugs while firing weapons in the army, and brought them home and wore them in clubs too. Rick S First off, thanks for hosting these. They are a lot of fun to play with. Second, there seems to be something different about the WAV files at 21,000 and above. Maybe something in the encoding? I'm 41 and I can hear everything up to 17,000 and then eveythign over 21,000. That shouldn't be possible. One other note, I downloaded all the files to my local hardrive and played them through my headphones, and then I could hear them all. naXoz Im 15 and i hear 25000 but not 23- and 24000???:/ Rick S First off, thanks for hosting these.

I wonder if this is due to my speakers not being able to play above this level because I hear 20,000 clearly. Be well, Jason:) Jason Izen Also I forget to mention I can hear the 2 sound samples just fine. Be well, Jason Izen JP 31, and at 22k I start second-guessing if I'm hearing it, or imagining I'm hearing due to the static clues at the beginning and end. Sarah I'm 16 and I can only hear up to the 20K, but my sisters ages 6 and three also can't hear higher than that, so I think it might be the speakers. We can all hear 20K perfectly. Trevor I'm 16, and can hear 19,000 quite clearly, but for some reason nothing 20K or above. That leads me to conclude it's probably my speakers. I'll try it on something newer soon. Alvarrr I could hear all of them and I´m 31!!!I downloaded the mosquitone from http://www.mosquitone.net and it´s definitely working on the mobile. im gay :) i am so gay i can hear every high pitch noise.. i like pantyhose too Webdaze I'm 31 and could hear up to 19 after that I don't really hear anything, I just get a weird feeling in my left inner ear. you realize that all that you can hear depends on the range of your speakers or head phones can handle. Most speakers only go to 18KHz. Head phones usally go to 22KHz. Mine only go to 21Khz so thats the highest i can hear. Andrew Wiggin you realize that all that you can hear depends on the range of your speakers or head phones can handle. Most speakers only go to 18KHz. Head phones usally go to 22KHz. Mine only go to 21Khz so thats the highest i can hear. Frodo 21 years old here, and on my ipod earbuds i cut off at 18.000 Brandon Im 17 And I Can Hear The 20,000 just Hardly babun i hear till 23 hz nella im 13 & can only hear up to the 20,000 mark or whatever :| ptk im 19 and i hear at 19.000 Ty I'm 15 and and can hear the 19,000 and my dad who is 43 can only here the 13 000 nothing more. I them brought my dog in and got him to sit in the middle of the room. turned on the 25 after connecting the laptop to the aux unit and cranked it. I turned on the 25 played once his ears moved and he started to look around showing that he hears somthing. I then after a couple seconds of him just sitting there looking at me i did it again his ears moved and he walked out of the room at a good pace. Tito age:56 male Heard all of the clearly Richard I could hear them all, maybe put some more sounds up so i can see how high i can hear :/ , im 18. also: stop advertising e.g WWW.crappy-ringtones.com bad kids. LJ Is this place for real. I first tried 10,000 and didn't have a real problem hearing it. Then I kept going up the scale. The sounds became easier to hear as I got higher in tone. The 25,000 was loud. I am 66 year old male so either I have a high ability to hear high sounds or this test is bad. Tara I'm 31 and can hear all of them. My kids can hear it from another room and its driving my dog crazy. RastaKins I am 47. 13,000 sounded loud and I could not hear 14,000Hz with the air condioner on. As expected, my left ear is better than my right. I ran the 13, 14, 19, and 20KHz sounds through a spectrum anaylzer to see if they are legit and they are. He changed the format of the sounds above 20K... he had to. The Nyquist (read cutoff) frequency of a typical MP3 is 22KHz. There were no harmonics in any of the samples I checked. I ran a spectrum on "sample 1" and saw a strong tone at 15.8KHz. Sample 2 is just a plain tone by itself... it is not a recording. It has a strong tone at 15KHz. Some of you say you can't hear 19KHz but can hear some higher. This is probably not true but instead is a limitation of your sound card. Most sound cards probably sample at 44.1KHz so you are probably hearing ALIASING which is caused when you undersample a frequency. Perplex You have to check your earphones wheater they can play more than 21khz ;) Ahmed I'm 21 years old. I can hear up to 23000KHz clearly, After that, they gradually get harder to hear. At 25000KHz, I couldn't hear anything per se, but I felt a strong pressure of some sort in my ear; a weird, ear-splitting feeling but with no "sound"! considering that I'd say my threshold was 25000khz :), any more than that and my head would've split in half! zachary I can hear up to 19,000 clearly but none of the above Cheri I turned 42 in May. I can hear up to 17,000. Starting at 18,000 I really couldn't hear, but my head hurts and I have some really pissed off cats staring at me...the younger ones are more pissed off than my almost 17 year old cat. ;-) I was also a piccolo player through college marching band and still play on occasion, so that probably killed my upper range hearing by my 20s. Jan Mowrey OK. I'm a 58 year old female. What I can hear depends on how high I crank the volume. With the volume way up, I can hear 22000 Hz. That seems to be cheating. I have tinnitus in the high-tone range and my husband is playing Stevie Ray Vaughn in the background which doesn't help. Question: at what volume should we be able to hear these tones? Seems to me it makes a big difference? My tinnitus seems to be matched at the 13k to 14k levels. This is kind of handy for a tinnitus comparison. With my volume set at a rather uncomfortable 60%, I can hear tones to 20k. Have to set the volume at a very uncomfortable level to hear up to 22k. I wonder if any of this presents any enlightenment on tinnitus, which is an incredibly annoying affliction. J dani 22... and i can hear up to 18000, but then my ears arnt the same..ggg Danial hmm. i have a problem. at 20kHz and over I have to download it and hear it over Winamp, which qualitiy is not as clear as my browsers sound. On winamp I could hear 25kHz, but not 21kHz. I'm 22. Danial again I must correct myself. I can hear both 21 and 25, now I tried every frequency. But 24 must be defect, because I can hear 25 clearly but nothing from 24. Except there is a possibility to be deaf on a lower frequency. Kelli I am a 43 yr. old female and I could hear it at 15 pretty clearly, but after that I could just kinda feel it in my head. I do remember being able to hear sounds like in malls (in the days of annoying lighting) and the adults never could. Explains alot for me~~thank! Graystar I'm 52yo male & I could hear them all. but I don't think my Creative Labs speakers are up the the task of reproducing hi-freq sounds accurately, in spite of their claims. Bob & Tom played one of the mosquito tones on the radio and I could hear that easily. Also,I can hear leaking gas jets in homes that have that problem and it sets my teeth on edge while driving me up the wall. Thanks for the reminder. I understand the military & BATFE have ultrasonic "denial of theatre" weapons now that are used abroad and domestically. Mr. Man I was able to hear 17KHz clearly and bearly bearly hear 18KHz. One thing that suprises me is that so many people have HiFi stereo systems hooked up to their PC's... Logitech, Koss, Creative and other "PC" speaker systems can't accuratly recreate these frequencies, and in most cases they can't recreated the top end of these samples at all. Millie Schafer I'm a 54 yr old woman. With the factory-issued Dell speakers turned up pretty high I got to 20. Have had tinnitus at 13-15 all of my life. I've read that this is the the residue of all the sound waves out there. Did anybody's pets get jumpy at the really high frequencies? Not scientific, but fun anyway to see how many people did this. this kid named shaun I can only hear past around 18k Bruce I can hear (sample 1) and (sample 1 slowed down). I can just hear a faint click on all the other choices but absolutely no sound on any of the other choices. I think there is a defect or my speakers are not working, speakers are stock from a 1998 IBM 12 Mg 400 windows 98SE. (A 60ish year old man.) Chantelle I can hear up to 20k pretty clearly. Past that is a faint buzz. 15 year old female. Dan Can hear up to 15 no problem and can just (barely) pick out 16 if I listen carefully with headphones (17 is so faint it might be my imagination). Can't hear Sample 1, but can hear Sample 2. I'm 45. ear master I can't hear 24000, but I can hear 25000. Is that possible? I played 20,000 - 25,000 in foobar2000, and it has a visual thing which I guess is somewhat accurate because music files show activity at the low end. However, 20,000 shows activity at the high end, but then 22k, 23k, 25k show activity towards the middle, and each one does move to the right slightly. 21k and 24k show a straight line (the other are like curves with peaks). Either my player is playing them wrong or they're being displayed wrong, or the files themselves are wrong, or some combination of all. Rob I'm 18 and I could hear them all with relative ease. For above 20 though I had to take my headphones off of my neck and put them on. Mahmut I´m 24 year old! I can hear anything,except 20,000 and 24,000 kHZ Roy despite the inherent deficiances in the samplings-the biggest factor being my laptop has enough fans to achieve liftoff-i could hear up to 20K, and i'm a few heartbeats away from 60. have fun guys. fuska a copy of the samples with delicious playtagger, for quick test your friends: http://rooober.googlepages.com/testyourear%21 George I could hear all then I realized I was hearing an overtone and not the true sound. I rudeced the volume to a min and played with my ear close to the speaker and I could still hear all freq but after about 15000 its hard to hear and problely would not notice in a room full of people The old man I'm 46 can hear 12,000 fine, nothing at 13,000 or past. I'm sure my wife asks me to do chores at 13,000kHZ +. would explain a lot. ThereIsNoSpoon Ok, it has been said already but it seems to need repeating. A newborn can hear up to 20'000 HZ for the first few months and then that goes down. Everyone who heard 19'000 and higher haven't done so because it is physicaly impossible. However, there is a audio norm called HiFi and that means, that devices labeled as such must be able to reproduce 20HZ up to 20'000 HZ. Now, your average little computer speakers and chat headphones are usually only able to go as high as 15'000 HZ and after that you hear phantom sounds, or downmodulated sounds. I can hear up to a very faint 16000 HZ at 25 and that's the upper limit for someone my age who lives in the city. Jose I could heard sample 1 then all of them except 21.000 - 25.000 hz, 13.000 and 16.000 made me get angry, i'll never do that again! i'm 21.... John Im 34 years old and I could hear everyone except 24k. Not sure why. steve i am 51 and i could just hear 14000 htz but to use as ring tone i would have to drop down to 13000htz but its to be expected years in the army in both artillery and aviation and now a police officer - lots of noise Billie I'm 68. Could hear up to 22,000 with a low constant hum, and 21,000 with a high-pitched squeal. I have regular cheapy Altec-Lansing speakers. There was a store in town that used to have squealing automatic doors that drove me nuts! Anyway, my ex-husband used to say I had ears like a dog.....glad I've got some talent!! Arizona I'm 64 and after almost 6 years in the Navy Air Farce around A3D bombers ( long gone now ) 2 engine jets and then 33 years in construction with lots of noise --- I can still hear the 20,000 but NOTHING above. Some frequencies I can hear better than others. Although I did cheat a bit .. turned my little el cheapo speakers up almost full blast. I'm surprised I can hear that well without my hearing aids. Although I did get them in order to hear women better because of their higher pitched voices. chicago I'm 16 an I can hear up to 20,000 even though I regularly drown my ears in ipod music. David "Eh... not so much" mentioned the NY Times article. I could hear up to 19K on this site but I couldn't even hear 17K on that site. I like this site better :) Azumi Kataka Could hear every sound till 20,000 Hrz It's a pity that my browser said "broken file", couldn't test 21,000 - 25,000 Hrz. Dunno if I would be able to hear them. I'm 19. Kristin I am a 40 year old woman and I can hear all of them. Granted the ones above 17K are harder to hear. Joe I'm 28 going on 29, I can hear everything up until 25khz. Oddly enough, the 17k and 18k give me a wierd floating sensation, then it's like I'm only hearing the harmonics because the tones at 20k seem lower then 16k. Odd that nobody else can hear those too. When you try this, try both speakers and headphones just in case your speakers can't output above 15k (some speakers can't, oddly enough) i hear nothing its maybe the fact that i cant hear high pitched sund but i hear nothing Kelvin I can hear upto 20000Khz very clearly but 21000Khz seems to be really faint. The difference between 20000-21000 in terms of volume is day and night to me. Surprisingly I can't seem to hear 17000Khz that well. But 16000 and 18000Khz are both really clear. I'm 28. I wonder if its to do with my crappy tele-marketing style headphone though. Keith I'm 49 going on 50 and I can hear all the way to 24,000 HZ. Andy I can hear subaudible noise. I turned my volume up all the way and could barely hear Sample 1. SAMPLE 2 was obnoxious! Starting at 21000Hh and up I could hear tones that sounded like a hearing test (the subaudible ones I am not supposed to hear). If someone had one of those ringtones, I sure would wonder that that noise was? As it is, I hear obnoxious ringtones and wonder that that noise is? josh this is funny, the louder it gets the more you can hear it, that is if you have a pair of sennheisers. david which sennheisers do you have, the 650s can go up to 39000hz, yea i wanna test that, can you get more frequencies up Laura I got up to 19,000Hz on the samples I couldn't hear the 20,000Hz but the last one I could hear was the 19,000Hz one basilbub I'm 34/male and I can hear them all. The higher ones are quite annoying, too. I can also hear those plug-in "pest repellers" that only mice are supposed to be able to hear... Jovenn I am 26, and I can hear all the way to 24,000 Hz. Paul Something weird is going on for me between 16k and 19k. 16 sounds higher than 17 which sounds higher than 18 which sounds higher than 19. I'm not an acoustic engineer but someone previously mentioned something about filtering out the harmonics. I'm wondering if that's what I'm hearing rather than the target tone. Incidentally I can hear a tone up to 23k but I couldn't swear that I'm not hearing a harmonic jeff Yeah i'm 22 i could hear the 20khz 21 and up i could hear them start and end. I think that I could probably hear them if they were more than 2 seconds long. Not sure tho. I've also worked alot of jobs that cause hearing loss. And yes that noise the monitors make are annoying. I broke one of my monitors because of it. ??? I am telve years old. I could only hear up to 18,000 Hz. Is that weird I can only hear that much? Timothy Castelli I am almost 22 and with the volume up, i can hear 25000 clearly. this is with basic speakers. Nothing fancy. Rantolotl I'm 24 and could only hear up to 16,000. But I'm kindof deaf. chuckie 35 yr old male. i'd say my cutoff is 19k. Can hear 18k quite well. sa rose My ears or speakers or both peaked out at 16000. I'm too afraid to plug in my Etymotics! Oh wait...hubby wants a go at it. Well? He only got up to 14000 with the Etys. We're in our mid-30s. We have a friend that can hear all fluorescent lights, background noise or no. Also in his mid-30s. I think it's a matter of individual difference, although the majority of folks may fall into these categories. sin i could hear all of them as well. im 17 :D Sue I'm 62 and can only hear up to 13,000. No wonder I keep saying "what did you say?" naver i can hear up to 25000 but is onli 24000 cant hear??? stargirl I'm 46 and I can't even hear the 10000 :( Frank Chiavino I picked up 20,000 at 31 years old. I didn't hear nothing at 21,000 Being I'm a Beat Smith it's good to know my drums are tight. alex I am 20 and i can hear 25,000. Cheryl Fontaine I am 61 and have had tinnitis for many years. The only high-pitched sound I hear is constant and unremitting; but tell me, so what if the teacher can't hear, surely s/he knows if a student has a phone plugged into their ear. The education they're missing is their own. Nancy I am 63 (ancient, I know,) and I can hear clearly through 21,000, I am sorry that so many young folks cannot hear as well as I do. Geno 55 this year. Could hear them all but above 20,000 they were faint. Gwen I could not hear 12, 13, 17, anything over 20. I am 71 years old and I guess I had better get my hearing tested. sam mid 60s can hear 10 & 11- barely 12. then nothing til 21-25. these are very loud- but also lower in tone than the 10-12. so it's just qbout the opposite if gwen who is 71. so, what exactly does this mean as far as our hearing?? i don't get it. JumpinJackFlash Don't feel 2 old and deaf - I'm 51 & had to go down to 14 b-4 I could hear it. Thanks 4 deciphering this ringtone Jami I'm a 17 year old girl and I could hear them all clearly except 20,000 and 24,000. I turned the volume all the way up and I still couldn't hear them! That's a little weird I think. Also some of them got fainter the the last one that I heard and then they would get louder, higher pitched again?! And now after I've listened to all the frequencies, my ears won't quite ringing. lol! Joe I'm 35 and could hear up 23,000!? Do I have super hearing or something? All this time I'd thought my hearing had been severely damaged by The Walkman. Alex I am 13 and I could hear 20,000 hz Matt 19yo, could hear 20,000Hz Ala Hm, heard up to 24000... except the 19000.I just heard nothing O.o Bit strange... I am 20 by the way Brent 33, and I can hear up to 18000. Lou I could clearly hear 13000, but could not hear 14000. I am a 54 year old male whose wife is always telling me I'm deaf. I also play electric bass guitar in a classic rock/blues band. Edward I'm 36 and I can't hear crap. I could hear 12,000 but not 13,000. Sucks. I'm going blind too. Brad I'm only 20 and I could only hear up to 14,000 smyph i am 25 and could hear up to 20, 000 Jim Caputo I must have very strange ears. I'm a 45 year old guy and I could hear everything up to and including 23,000. I couldn't hear a thing at 24,000. But then I went to 25,000 and there it was clear as a bell. I'm not sure if that gap is good or bad. I'm going to assume that it's good because that makes me feel better (and isn't that what it's all about?). I'm going to chalk up the good ears to being a musician/singer/songwriter. www.jimcaputo.com phaet 31 and can only hear 12...:( nijkerk 56, 17000 is plainly audible, with very bad computer speakers. Lex I'm 46, misspent several years of my youth in front of a stack of guitar amps, and the highest I can hear is 13,000 Hz on a (cheap) pair of earbuds. I've got excellent speakers on my home computer, so I'll see what difference that makes. AudioGuy I am 35, an audio engineer, and can hear the tones right up to 25,000 Hz. I am also listening through JBL studio monitors (LSR 25P). I am used to critical listening to discern between sounds. Jim Lendall At 15 and 16 I heard nothing, but at 17 I could. All of the frequencies above that were not able to be run by quicktime. Dan I'm 64 and I can hear the 10 k whistle but not the 11. When I was young, I could hear the 16k horizontal oscillator signal in a TV, but others could not. Jerry Right with you, Dan! My 62-yr-old ears can hear 11 but nothing above--are you *sure* those higher ones work?! Ba'al I'm 49. I could hear 13 kHz, nothing above that. Ba'al Actually when I cranked the volume I could make out 14 k. Interesting and depressing. Clarence 43 year old male. I could start hearing something at 20,000 Hz. Larry I'm just shy of 49. I can hear up to 1400. Can't hear 1500, but when I turned up the volume I felt it. Disorienting, Uncomfortable, could be very painful at high volumes. Tom 58 and hear clearly 12k, 13 less, and pretty much nada above. That is a little higher than average, but still typical. The roll off frequency for me starts at about 10k, and the curve of descent is gradual to 12k and steep starting about 13-14k (this is audiometer). Actually, though, I can "hear" up to 16k and higher, by means of very good pitch memory and other physical sensations. Under certain conditions that don't seem logical, I can "hear" distinctly a pitch I recognize from memory, and for psychoacoustic reasons I have a thought reaction. So I have adapted as I've got older. But no way will I hear the cell phone pings, but I may be able to register them, and become annoyed. Arthur 50 male age 50 16000Hz. sa I can hear 15,000 in my left ear, but not my right, in which I have tinnitus. (Funny thing is, the ringing that is usually in my right ear is all but gone -- Of course, I didn't notice if it was there right before doing the test.) ambrosia I'm 24, and I can't hear any of those. I've never noticed a problem with my hearing before. Brod This is a put-on, right? I mean there isn't really any sound, um, is there? Otherwis..... Well I am 64. Jonathan I just turned 28, and I can mostly hear up through 20,000 clearly. Although, curiously, I can barely hear 16,000. And with the two initial sound samples, I can hear Sample 2 clearly, but when Sample 1 plays I can only hear background noise and a periodic (~1-2x/second) high-pitched beat. Roz I'm female and almost 44. I could hear up to 21000hz, after that it was dead air... Bat Guano I played 25,000Hz, and it made my cat's ear twitch. He looked at me as if to say, "knock it off, please." Me: 39, 16,000Hz, none higher. Jeff Im 40 and I could here at 22,000Hz ScottSTL 22 yr old male with excellent hearing -- range and acuity (do some work in A/V production/editing) -- and I can hear them all at fairly low volume, though 23-25 kHz aren't as loud/noticeable as they used to be.

I don't know where my hearing tops out -- my computer speakers stop reproducing sounds somewhere around 15000 Hz. judyo I'm 64 and I can hear 12,000 without adjusting my speakers and 18,000 if I turn the sound a little past halfway. Whatever Download links from 20 khz up are broken, till then i could hear them all. Alan No human can hear 25 KHz. People who are hearing the sound in this file are actually hearing noise or artifacts at a lower frequency generated by their soundcard and/or their speakers. If you are actually hearing the high frequency sound, it will audible hear it, it will sounds like a very high pitched whine, and it will make your ears feel like they are about to burst. If you go up in frequency, but it sounds like the pitch is actually lower, then its not working. Will Poom said: 'I'm older than dirt but I can still clearly hear the 10,000 Hz sound.' So can I, but nothing higher. Could that be interpreted to mean dirt was created in 1943? Don't anybody tell the Intelligent Design idiots... Dick Brass I'm 55 and I can hear the 17k, but just barely. My wife who has damaged hearing, can't hear above the 12k. Our yellow lab Willy seems to hear them all, except 25k, but then he's just 2 and he is a dog. I used to be able to hear 23k+ until my late 40s, and even better when I was young. Fifty years ago, at our kindergraten hearing tests, they kept me for almost 20 minutes: wearing the earphones, listening for tones, and raising my finger when I heard one. When they finally let me go, the audiologist whispered to our teacher, but I could easily hear him. He said: "That's not a boy -- that's a bat." Not anymore, alas. Marnie at 57 I can hear 10,000 and 11,000 then nothing. I am aware of a discomfort inside of my headat higher pitches. My cat clearly heard all of them,,,high pitched noises make cats anxious and needy Dick Brass I'm 55 and I can hear the 17k, but just barely. My wife who has damaged hearing, can't hear above the 12k. Our yellow lab Willy seems to hear them all, except 25k, but then he's just 2 and he is a dog.

Dumbo I hear 13,000 fine. 14,000 and above, I can't hear. I'm 49. There is a possibility the speaker quality may have some bearing on things. I have cheapo Labtec speakers. ScottSTL 22 yr old male with excellent hearing -- range and acuity (do some work in A/V production/editing) -- and I can hear them all at fairly low volume, though 23-25 kHz aren't as loud/noticeable as they used to be. All are annoying! Bruce 52 here and can hear up to and including 21,000. KK 27 here, was able to hear 20K, but not beyond. mendyourfuelishways.com 34 yrs, can hear up to 17K. Same with the wife at 32 yrs old. Kirk 38 here - heard all up to 23000! The other two see, to be out of range for me though.. :( Gurble I'm 38 and heard each and every tone. Plus, I've spent 25 years attending every concert I can make i to and working almost daily with headphones. I guess I'm just a freak, or part dog. DrBB I'm 50, a life-long rock & roll musician, and I can hear 17K just fine. 18K was a maybe, nothing beyond that. Enja I could hear the tone up to 1800 and I'm 57 Enja I could hear the tone up to 1800 and I'm 57 John My cat is 7 and she says whe can hear all of them. However, I am retired and couldn't hear anything except maybe the 10er, and one of my ears hurt a little during the test. Redleg I am 42 and I can hear up to 20,000. That's odd given that I was in field artillery for 5 years. donn 59 can hear up to 13000 Thebes I am 34 and have very good hearing for my age. 15k is painful. 16k is very obvious, but fainter. 17k and 18k I can tell something is there but not what it is, I would probably not notice it if I were not listening for it. Adam 31, Male 20K hurts like h*ll - 21K is audible. 15K sounds about like a tv set with the sound off, 19K sounds like the display on a HP-48gx calculator. I don't listen to rock and roll or watch much tv Adam Again There's something wrong with 22K - I can't hear it, but I can hear the higher tones. Dan I'm 16 and i can hear up to 24,000. Matt It might possibly be my computer, but when I open any file after 20,000 it tells me that the file has moved. Nay I'll be 50 in two months and I can hear up to 20,000. Can't tell about the higher ranges as all the ranges above 20,000 don't work for me. Broken links. James Age 63, permanent tinnitis in both ears, but I can hear the files up to 15K inclusive; the trick is to crank up the volume! Also, beware of possible subharmonics from audio reproduction distortions. Left me with a headache... Debi Age 55. I was able to hear 20k. Nothing after that. The only one I couldn't hear lower than 20k was 18K. Go figure. I wasn't listening through ear phones, just using the speakers on my PC. andreas I'm 38 and i can hear up to 23,000. Larry Massey I am 64 years old, listen to a lot of music, but I don't hear squat at any frequency. Terr 22 years old. On normal listening volume, (headphones chained through speakers through onboard sound) I can hear the 20k and nothing higher. If I crank up the volume 21k: Nothing 22k: Yes 23k: Yes 24k: Nothing 25k: Yes 21k and 24k appear to have a different sound spectrum shape in my media player than any of their contemporaries. The peak has almost no "slope" to it. It's just a single line among nothing, rather than a pointy mound. Maybe 21k and 24k are malformed compared to the other samples? Fofo I am 45 and can only hear 15k. By the way how could it be used as a repellint for mosquitos? Anastasia I'm a 45 year old woman and I could hear up to 19,000. However, the links were broken for anything higher. But 19K was loud and clear. WHEN I'M BLUE I'm 39 and I can hear it all, even 25,000 is piercing. Could my computer be messing this up? Brendan could hear all upto 25000Hz Ara I was born during the Eisenhower administration and I can only hear up to the 11k tone. Damn that Eisenhower! Hope I die before I get old. Alison I'm 27 and dyslexic (sounds strange but it makes a difference to what I can and can't hear!) I can only hear up to 14000Hz and then it's all over but now I feel sick, I'm having trouble seeing and my ears hurt like hell. Bit of extra info for you to think about....... when I go to a pub/club/event with lots of sounds going on I hear lots of noise but can't single out any individual sounds so a conversation, for example, is impossible. When I have been in that environment for a little while it's as if I go numb. the sounds merge further into a mumble and i physically feel like I'm surrounded by a bubble blocking me off from everything else. SARA I am 65 and I can hear a low buzzing sound @12000Hz and a high pitched sound very clear and strong @ 15000Hz. My hearing is still very acute and I can hear tv sound at a very low range.Anything very loud for me is very annoying. I was amazed at the test as I was expecting different results after learning about this ring tone. SARA Sorry. did test wrong 1st time. I am 65 and I could hear the ring tone from 10,000-25,000Hz.My hearing is still very acute and high volumns as tv and radio are very annoying and give me headaches.I guess my grandchildren will not be able to fool me with their secret cell phone rings. Tom R Hmmm....there seem to be certain ranges that I cannot hear. 10,000 to 15,000 - I can hear fine 16,000 to 19,000 - Can't hear a thing 20,000 to 23,000 - I can hear fine 24,000 and 25,000 - Can't hear a thing. Am I just weird? Bisqwit The audio hardware of a typical PC just doesn't do well with high frequencies. Also, the digitizing process destroys high frequencies. Due to 48 kHz sampling (or 44 kHz), over 18k the waveform starts being so low resolution that the harmonics can be heard easily. BiJae Great sight. I heard about this 'phenomenon' the other day on a morning radio program. They played a tone on air. I didn't hear it. An imstant skeptic I thought this might be a practical joke I did a little more research and I found the tone they played. Now having your site in my arsenal, I'm glad to report that this 33 yo male can hear up to 17,000. Phwew... Will have to check back over time and see if theres loss. "Buford" After 20 years in the military with all the explosions and aircraft, and working NHRA events, my threshold is at 22kHz; I did screw up my hearing in a motorcycle accident, which damages the auditory bones in the inner ear. I have a constant ringing of approximately 24kHz. I also was an audiology technician for the Air Force for 3 years and saw the damage caused to individuals with the "boom-boxes" and "walk-mans." Protect your ears cause they can't be replaced. chris I can here them up 17 k but I think my speakers can't handle the level . I am 35 I had my right ear operated on twice and now I can hear extremely high freq with that ear but the 400 to 800 range is very weak . ben 21,000 at 16 LL_ I am 50 years old. I have worked with loud noises most my life, the first 25 years without hearing protection. My ears started ringing in the summer of '2003' and only stopped one time in Sept. of '2003', but for only minutes, they continue to ring all the time . Doctors say it is not a ringing in my ears but rather inside my head, they say it is not normal but yet not uncommon. I could hear your test at 11,000Hz. Spiderman I can hear all of them easy, but then again I do have superhuman powers. carl 28, 19K and to a lesser extent 20K I couldn't quite hear but when I crank the volume and put my ear close to the speaker I get this feeling that I should move away from it. Thomas I can hear the 19k and 20k, but just barely make out the lower frequencies. I'm 48. Pad I'm 21, and I can't hear anything over the 15. I also found that if I play two I can't hear at the same time I can hear one tone. Dave I'm 27 and an Audio Engineer. I was relieved to hear that I could still hear 22khz, and surprised to hear an extremely faint buzzing at 23khz. However, someone else did point out that throughout all the samples there are both upper and lower order harmonics that have not been filtered out. Kini I'm about to turn 52 and I could hear up to 19,000 but nothing beyond that range. Doug I am a proffesional guitar player and audio engineer for 22 years. Played in very loud bands throughout those 22 years. My ear is very trained as I learn all songs by ear. I can hear all of the sound clips, even the 25k. Is there a sense that gets developed better then the average person when learning songs by ear, as well as doing studio recordings? OldFart SAY...I COULD NOT HEAR ANY OF THEM...WTF? Melissa OMG.. that was to funny.. I thought for sure my speakers were bad when I could hear 14 just fine up 15 I heard NOTHING.. so I asked my friend to come over and tell me if she hears anything.. I didnt tell her what was gonna happen HAHAHA!!! I played 15 and she damn near screamed!!! She could hear all the way up to 20. That was hilarious though!!! I know I have bad hearing.. I always have. Tom G I'm 38 and heard up to 23K. 16K was faint, but audible. Mimi Age 65, and could only hear thru 11. Yep, that confirms it---I am getting old! lol Mimi Just went through all of them, and found I could hear a little bit at 22 and 23, too. Weird. LeeboZeebo I'm 24 and I can hear up to 17, so I suppose that makes me more or less average. I can barely make out 18 if I turn the volume on my speakers all the way up. This exercise highly annoyed my cat, which alone was kind of worth it. Cole 14,000 was clear. 15,000 just barely audible with the speakers turned up. After that, only a slight sensation of pressure. I'm 41. kathy I'm 49 yrs. old I can't hear anything above 13,000. What? Did you say something? Richard I'm 63 and can hear the 13,000 however my lab soon left the room with anything above that. vertyeux I can hear all the tones except 16,000 - 20,000, for whatever reason I can hear them again starting at 21,000. However, I do have tinnitus and that's probably the frequencies my ears ring at. vertyeux I can hear all the tones except 16,000 - 20,000, for whatever reason I can hear them again starting at 21,000. However, I do have tinnitus and that's probably the frequencies my ears ring at. Oh, and I just turned 36. Gerry just turned 37 and i'm glad to say i can hear all the tones.... James Cates I'm 43 and can hear 22,000 nicely. 23 is just barely audible to me. Mike Fun. At 63, I can hear up to and including 21kHz. Time for an earwax cleaning. [turn those damn speakers down!] Sandy Female 28 - can hear all upto 20,000 Hz but can barely the 17000 Hz. Selective? Shannon I'm 14. I hear all of them clearly. I think my ears are bleeding. Is this what a dog whistle is like? Poor puppies! frizzi i could hear 20.000 and im 24 ! Tom I can only hear up to 15,000 Hz... :( Tom Oh--and I'm a 30yo M Sirakath I could hear 20,000 VERY clearly, 18. I went up to 24,000 and everything above 20,000 made my head and ears hurt. 25,000 didn't phase me. Josh they are all annoying and after showing all my coworkers and listening to the frequencies for over 30 minutes it gave me a headache and i was disoriented. im 19 years old and most my cowrkers could hear anywhers from 17k to 21k most younger ones could atleast hear up to 19k and 20k was harder for most only 1 could hear 21k and i sit at 19k and i can barely hear 20k with the volume maxed out! Lordi I can hear 25,000 and I've been listening to death metal for 20 years. Xavi I can hear all, 25.000, and i'm 16!!! ephraim i heard all yeah me!!! Lordi I can hear 25,000 and I've been listening to death metal for 20 years. Drew I'm 49...couldn't even hear 10,000. Sighhhhhhh. Chris 37/M I can hear 24,000 but not 25,000 Dick Brass I'm 55 and I can hear the 17k, but just barely. My wife who has damaged hearing, can't hear above the 12k. Our yellow lab Willy seems to hear them all, except 25k, but then he's just 2 and he is a dog. I used to be able to hear 23k+ until my late 40s, and even better when I was young.

When they finally let me go, the audiologist whispered to our teacher, but I could easily hear him. He said: "That's not a boy -- that's a bat." Not anymore, alas. Greg I can just hear the primary tone at 20K; the first and (especially) second order harmonics start to dominate at the 16K to 18K frequencies for me, but the primary is still there. The primary tone is actually clearer at 18K and 19K than at 17K - perhaps a reflection of the recording technique? Who knows. At 21K I can only hear the harmonics. Pair of 51 year old ears here - long time rock, blues and jazz fan, bass and guitar player, former trumpeter. Surprised I have so much high-frequency left! cory Where do i download the ringtone at????? hardy fantastic! I get to drive my kids crazy!!! and my dog scampers out of the room!!! I can't hear above 15K and I'm 43 - I don't think that I am missing a thing. korynthyan Could hear up to 18,000... not bad for a 30 y/o :) joe i'm 45 and could hear to 18,000, above that nothing. I have excellent health for my age. I wonder if health accounts for results, or how much? Jimmy2006aus I am 63 and couldn't hear anything above 13,000 hz. I Found this site from the Kim Komando website, fredly2006 Heard them all but 24,000. I just heard a couple of clicks in my head phones. I didn't here Sample one till I listened to it again after listening to your slowed down sample. Sample 2 no problem. fredly2006 Forgot to list age = 41. Stoney I cut off at 19k myself (age 35) I decided to edit a "medley" with an editor and make it a ringtone. To my amazement only ONE of 17 co-workers could hear it (but didn't identify the source) As a result I've been playing up the idea that I am a little "Psychic" when it comes to my phone. Nobody has figured it out yet and I've had a ball. Its even funnier when the dog wakes up barking from a dead sleep and I grab the phone (profusely thanking her for letting me know the phone was ringing) This just freaks EVERYONE out!! steve I'm 61. I the highest I can hear is 13 kHz. Beyond that, I can tell something is there but it's not like hearing a tone. One note: I don't know how these were encoded, but "CD quality" can't go beyond 22 kHz. What I'm seeing on my XMMS (Winamp) scope is beyond 20 kHz the decoding starts to break down and you're hearing a lower harmonic. steve Re: Stoney's comment. Good luck trying to find the source. People locate sounds by two methods. Left-right is detected by phase shift, the waves hitting the ears at slightly different times. At high frequencies this breaks down because the wavelength is shorter than the distance between the ears. Front-back is detected because the shape of the outer ear attenuates various frequencies differently from front and back. This works with complex sounds, but a simple tone has only one frequency. My dog barks at the phone anyway, no encouragement required. Lloyd Wabbitt I could hear a definate pronounced warble in there. That's where things get nebulized and cross-polinate things to place. Perhaps coaxial flutter is to blame. Either way, a pleated approach might work best in this instance. Milknut I think that my laptop speakers are sh*t. Well, I KNOW they are, because I'm a ripe young youth, but only heard up to 19000. The speakers just made little fuzzy noises at intervals, so I really think it's them. gaaack2003 Im 47 and I heard every single one of the samples,try going higher. barbara I'm 53 and I can hear up to 21,000. le ceck nouveaux wow, this is great, Im 23, inactive musician, and Im losing my hearing :P - what great news! Btw, i can hear up to 18k, but maybe I'm "believing" i can hear 19k. Jill I heard it at 15K. I'm 37. Dixie Im 24 and could hear all the way to 24. My 4 & 7 year old daughters couldnt hear 24 though. The highest they got was 22. Bob Using headphones, I can hear everything perfectly up until 20k. In 21k-25k I can hear the same 'clicks' I can hear in the other files, but not the ringing tone. I'm currently 32. Sami I'm 15, and I can hear all of them, and actually I hear the 25K sound louder than the ones between 20 and 24. But I think that I can hear them only because of my speakers, which are pretty high quality, or at least expensive :P Maybe it's a "feature" that they lower the tone... Jack im 42 and 12k is it for me... Dave I am 42 and normally wear hearing aids and without the aids I am able to hear all of the tones. Desmond Im 31 and hear 10 to 17 then it goes out - then all of a sudden 22 to 25 i can hear again even louder than 10 MarkJ I am 53 and was able to hear 14k clear, but nothing past that. ctp I'm 40. On my work computer, I couldn't hear anything higher than 13,000. At home I heard them all. Must have something to do with soundcard, speakers, etc. P I couldn't hear any of them. Do I need speakers for this? Jeremy and Jen i'm 30 and i can hear up to 19000 hz my wife is 30 and she couldn't get past 16000 hz and she bitches at me for being deaf Penni I am 45 and thought my hearing was gone but I heard all. But the strange thing is at 25ooo I only heard it half the time. Very weird..... Shawn I am 38, and can hear only up to 12,000 HZ, an unpleasant surprise! My girlfriend was in the other room, yelling that it was "killing" her ears, so I know I should be hearing something. And I have avoided loud music, must be hereditary. rusty i am 36, i could hear 14,000, my 10 yr old daughter heard the 20,000. i am an auto mechanic and work with air tools and loud exhaust for the last 12 yrs, that is what most likely did me in. lol, thanks for the test. korynthyan Could hear up to 18,000... not bad for a 30 y/o :) Stoney I cut off at 19k myself (age 35) I decided to edit a "medley" with an editor and make it a ringtone. To my amazement only ONE of 17 co-workers could hear it (but didn't identify the source) As a result I've been playing up the idea that I am a little "Psychic" when it comes to my phone.

Its even funnier when the dog wakes up barking from a dead sleep and I grab the phone (profusely thanking her for letting me know the phone was ringing) This just freaks EVERYONE out!! Patrick 39 and Glad I can't hear 17KHz JL I'm 50 and I can hear them all, that makes me feel good but I know I have some hearing loss in the 8 to 10,000 range. I have to struggle to hear 11 and 12,000.it becomes clearer above that. Anon I could hear all the way up to 25khz, does that make me weird? kris im 28, i could hear very little in the 16KHz frequency, and my head is like spinning now. I try to increase/decrease volumes on the 17KHz freq, but I could only hear the sound resulting from changing the volume in the desktop...although I could feel that when I turn the volum up at this range, i feel like my heads being squeezed or something...hmmm...this is interesting, i may want to use the 20 kHz to make our neighbors dogs crazy... Sue Booth That's really interesting! I'm 37.5 years of age, and I can hear all of them except 24 and 25. Adi man i'am 16 and i hear all of them and my dad hears all of them part from the last one Formage 16 here and i can't hear past 17,000 oooooooooooooohhh Im thirteen and i could hear up to about 19000, 20000 almost makes my ears bleed juliet i can hear all of them and i'm seventeen... but they are very unconfortable! Kelly I'm an old 42 year old and can hear the 16K and then that's it. Tim I'm 15 and can hear up to 18K. Ipod's rock! Marzipan My husband puts on punk rock shows as a hobby. I've been to more punk shows than I can possibly count, and more often than not I end up jammed close to the amp. Consequently, I'm 22 and can't hear past 15K. Probably ought to start wearing ear plugs more often. But wearing ear plugs to a punk show is like wearing sunglasses to an art museum. Brian i'm 26 and I can hear everything except the 20,000Hz... As for using high frequencies to keep people out of stores it does work! I used to work in a mall. A couple stores down was a Sears who had about 6 TV sets hanging from the sealing by the entrance to the door for some display. Everytime I within 20 feet from the store entrance I would get extremely dizzy and nauceous. I eventually started to just avoid that side of the mall all together. Also my wife will turn the cable box off and leave the TV on. I'll walk into the living room and say "turn off the tv" and she will look at me like i'm crazy because she can't hear the ring she just sees a black screen. Lauren im 16.. and i can only hear up to 15,000... thats prob not good Mike I'm 46 and could hear everything up to and including 15,000. I could hear Sample 1 but not Sample 2. Mark I could hear all of the Frequencies except 24,000. And I am 51. Don I'm 73 and I couldn't hear a damned one of them! Exception: I could hear the background noise behind what was supposed to be a mosquito. Rene The first 2 examples i could hear both and then up to 23k then i couldnt hear a thing but i could 'feel' it... it makes me unconfable... Mikey Well, I played them both... I hear sounds like those at random a lot, when I'm trying to sleep or otherwise - and they are incredibly annoying, and extremely LOUD. Very loud, piercing, and annoying and it doesn't shut off :(. When I played the sound files, I jumped in my seat cause of how loud it was. Neil I am 73 with a touch of Tinnitis. I can clearly hear everything from 13 thru 20. I wonder why I can't hear the lower freqs........ Marina I'm Italian! I'm 12 years old. i hear all, but the 21Hz isn't noisy as the others. sorry but i learning english and i don't speak it very well. sam I can hear all of them except the 24,000, but after listening to them it makes me dizzy. noah this is cool... i can hear everyone exept 25 and 20 noah Oh yea im 14 Steve I could hear a damn thing. But maybe that is because I'm deaf! Mandy I'm 16 and I can hear all of them, and they all give me a headache. 25k sounds like my computer at work...... Amy I was just trying to listen to these, and my dog freaked out and started barking. I guess he can hear all of them. bert Cats and dogs, like other animals, hear different frequencies than us. So if your pet goes crazy, it's nomral. It's weird, but sometimes I can't hear the sound but it still makes my ears hurt.. Andre I'm Male/23 from Australia. I can hear tonnes of frequency in both files.. Sounds TERRIBLE.. The slowed down one was unbearable for even 2 seconds..... High quality sound setup from pc btw. Gary I am 47 and can hear up to and including the 20k recording however the volume seems lower on the 20k than the others. I can't get any of the higher one to play. I must note that I have had very good hearing all of my life and can hear lots of stuff that other people cannot. Good subject. Charles I could hear the 18,000 no higher. I'm 17 Jessica I could only get up to 18,000 Hz. Is that bad for a 17 year-old? Sasha im 13 and i could only hear to 19 but the others i could tell when they ended but couldnt hear the whole thing is something wrong? Richard Im 16 and can hear 20,000 Dave The only problem I have with this test is that it depends on the speakers or headphones that you listen to the sounds on. Some speakers or headphones can't even recreate 20khz... Also, some frequencies are not accurately reproduced at 44.1 khz digital sampling rate... In digital there are half steps removed and what you might actually hear are overtones compensating for the actual frequency... 44.1 khz sampling rate can only reproduce frequencies in a range from 20hz to 20khz... At least that's what they taught me back in recording school. Dave. Don I'm 63 but can hear up to 23 mamour ahmad yeah right.. R I am 51 and could hear up to 11kHz I Agree with BBoy He's correct about limited frequency response of many headphones and computer speakers. The only way to determine what frequencies you can hear correctly is through the proper equipment. But just for the record, however scewed, I wasn't able to hear past 15,000Hz. I'm 38. John I can hear all except 16000 John For the record, I'm 37 nal.... heard 23K clear and 25K with headphones Alex 17/m and can hear up to 24,000 JR I'm 27, female, and could hear all the way up to 15k. 16k just evoked a sense of fear / panic. 17k-19k was just uncomfortable, however I couldn't actually "hear" the tones. 20k-25k evoked an instant, splitting headache until I quickly stopped the samples. Maybe everyone can sense the samples, but they have different ways of interpreting them -- for instance, 16k causes me to feel a sense of fear, but may induce a pleasant feeling in someone else (like a serial killer). jlee 52 and still hearing 21. No loud/vibrating car music or sitting at concerts with brain numbing speakers blasting in my ears. Most kids, today in 20 years, will be lucky to hear the 10. Karl I am 38 and have spent half my life playing loud music in bands. The 16,000 hz tone is the exact same frequency as my tinnitus... Chelsea & Katie woww... we're 14 and ours is 19,000 is that normal? or should we be able to hear more? Mark I can hear up to 20k with speakers turned up all the way. With headsets I can only hear 14k. 38m Josie I am 11 and I can only hear up to 19HZ ido Just out of curiosity -- what frequency analysis program did you use? How did you generate the sound files? If you generated them programmatically (i.e.: with C/Python/Perl/etc.), can you show some code? Thommy Very cool Site! I can hear up to 19kHz. I am 23 years old. Elise at the ripe old age of 18, i can hear up to 21. older than I want to admit Guess I am the oldest person to reply so far, I am 62yr. old female. Couldn't hear sample #2 until the very end then a short beep. As far as the others, with my volume turned up much louder than normal, 10 was very long and extremely piercing, 11 very long piercing but not as much,12 long and piercing, 13 piercing, 14 no sound, but gets my tinnitus going strong, ouch! Sean I can hear up to 19k, but I'm not sure my laptop/headphones are faithfully reproducing the 20k and higher. I'll have to give it a shot when I get home next week. I'm 32 in a couple of weeks. cait I can hear all of them. I am 13. carra I am 21 I heard the sound up to 19 from then on I felt only discomfort in my ears. In fact I have a headache now. I guess listening to Queen all the time doesn't do me any good! Ted 27 Year Old Male - I could hear the 18,000 as clear as anything. A.C. I am 68 and can hear all of the ranges you have. Of course my mother use to tell me to turn down the radio as it would hurt my hearing. Duane Nearing 61 yrs here. What in the world are you guys talking about, Huh? There's nuthin' on ANY of those freqs! Maybe those 5"x38s we fired in Nam from our carrier has something to do with it...dunno. audrey I am a 16 year old girl. im in band...so im used to loud music. and i could hear up to 24000. Duane Nearing 61 yrs here. What in the world are you guys talking about, Huh? There's nuthin' on ANY of those freqs! Maybe those 5"x38s we fired in Nam from our carrier has something to do with it...dunno. elise i tried again later in the day, and could hear up to 23 david I am 58 and I can hear up to 12 with the volume at normal level but up to 21 if I crank the volume all the way up. katelyn I was listening to the sounds and could hear up to 20,000 and I am 19. However, when I showed the site to my technologically savvy boyfriend, he informed me that most computer speakers have sound ratings. His speakers were only rated for 20,000Hz, thus he couldn't hear anything higher. Just so you know, it might not be your ears, but actually your speakers if you can't hear some of the frequencies. Bruce This test, taken on random computer systems is intriguing and fun but, alas, meaningless. From the supplier, we don't know the quality nor accuracy of the sound recordings. For the users, we don't know if the limiting factor is our ears, or our computer sound cards, speakers, headphones, sound file players, or some combination thereof. Sorry, but this is a helpful service with an uncontrolled implementation. Thanks for trying, Ochen, and nice site. Jodie I'm 27 and could only hear up through 13K :( I'm a music teacher, and hearing is important for my profession! My boyfriend pointed out the same thing that Katelyn did, about the speakers being able to output different amounts, depending on the speaker. He could hear up through 16K though, so in my case, it's my ears. sukhbir hi bro, iam a sound enginner in india. heard ur tones. i am 27 and can hear upto 20khz. i am doing a research on subliminal music. could u please discuss ur updates about this topic.it would be helpful if u mail it to my email id write2sukhbir@rediffmail.com Thanks a ton sukhbir Will I'm can hear them all but when i came to try to listen to 21000 hz it wouldn't let me and i don't mean i couldn't hear it my computer just couldn't listen to the files Andrew B I hear both and am also disoriented by both. The first one made me nauseous, the second one was like a siren. I am twenty years old. Sounds always seem to cut through me like knives. Christine Help! I'm really confused. What is the maximum number of decibels that these recordings can make, factoring in that the average speakers can go to about 120 decibels? Does the high frequency influence decibel ratings? Can hearing frequencies so high cause hearing loss if they are still in the appropriate decibel category? Mike I'm doing a PhD in physics, and if there's one thing I've learnt, it's that the more I think I know, I realise I know a lot less. I suggest this test is crap, and I didn't even check what I'm generating through my computer speakers for lower harmonics. As someone mentioned we have to make sure that the mp3 sampling frequency is at least double that of the highest frequency as a BARE minimum. This rules out burning these samples to CD and playing them on any home hifi. CD would be crap for this test. Sorry, but it's true. Secondly, can I be sure my speakers aren't somehow generating lower harmonics, stuck in some sort of resonance? Even if I was able to accurately tell my speakers to play 22kHz, how do I know that's what they're playing? Good time to add, most home speakers are crap for these tests. I reckon I know why lots of ppl can hear higher frequencies and low ones but not middle ones, and that's because as the frequency goes up, the speakers are for whatever reason no longer able to generate them, and instead they generate a lower harmonic, or perhaps they always were making a lower harmonic.... SO many possibilities..... Don't get me started.... BTW his FFT above looks Tiny. Mike Patrick I heard about this site from a friend and have vision problems because of a disease called Multiple Sclerosis.On the other hand my hearing is exceptional so am able to hear the 19 k with no problem.I think my hearing makes up for the other senses. Alfred I heard 10,000 with no problem and did you know 60 Hz was tested by the U.S.Navy at 100 db which subdues animals and you'll experience a loss of bowel control yyyy i feel kind of sick now and i also think after about 20hz your speakers mess it up a bit Arielle My BFF sent this to me and i dont have speakers, so 'yall have to tell me what's going on ... lol Beth I'm 50 and could only "hear" up to 14,000. But from 15,000 to 24,000 made me very uncomfortable in general, and threatened to give me an earache/headache. Now I know why my dog hates those whistles! Thromy I used the MP3 at www.RingRong.com. I couldn't hear a thing. But my wife could hear it in the other room, and told me to stop,when I played it on my phone. Don't know that I needed a new way to annoy my wife. Thromy By the way it matters at what volume level you play it at. My wife could hear the RingRong tone at a middle volume but not if it was really low. My kids could hear it even at a very low volume. I was using a T43 laptop and Windows Media Palyer with the MP3 at www.ringRong.com. It also worked with My E815 Phone. Boko I listened to 25000 for a while oh my god my head hurts, I started hearing 25000 after a while, I could normally hear up to 21000 I'm 14, I can hear all of them. My mom tested it with me and she could hear up to 15000. Nick Scott I found the link here: http://bbs.retrogade.com/topic.php?id=5129&p=3 And I can hear about 20,000 and I'm 12. A.M. I'm 10 and could only hear up to 15. I liked it. A bit. Becky Both my husband and I could hear up to 16K (we're 30 and 31), but both of us felt pressure in our ears for each file above 16K. After playing the 25K file, I had a headache and nausea that lasted a couple minutes. My dog could hear the 25K and was annoyed by it. Todd I found this very iteresting. I was opening the files, and somehow I got two open at once; one on windows media player, one on winamp. NOW when you play 18000 and 22000 at the same time, I hear a complete new sound. If I play 22000 by itself I can't hear anything, almost the same with 18000. Can anyone please explain this to me? girl me and my sister [me-15 my sister-20] both heard up to 20 22 yr old I could hear all clearly, except for the 24K one. I'm really impressed how one can hear one frequency and not others. But I'm still quite intrigued and puzzled how I was not able to hear the 24K one. As well, I couldn't hear the Sample 1 "mosquito". And, for some reason, if I open the 21K using Windows Sound Recorder instead of Windows Media, I cannot hear anything (though I could hear the 21K with WM)!!!. I tried as well playing two different frequencies at the same time, and I agree, the sound is a new one. Todd I found this very iteresting. I was opening the files, and somehow I got two open at once; one on windows media player, one on winamp. NOW when you play 18000 and 22000 at the same time, I hear a complete new sound. If I play 22000 by itself I can't hear anything, almost the same with 18000. Can anyone please explain this to me? Steve 23 years old, can clearly hear 18khz, 19 is inaudible but i can make out pieces of the 20khz one. I can clearly hear most television sets from several rooms away or down the hall, and can tell when something's been left on even if there's no incoming signal or noise. I wonder what frequencies most TVs emit white noise at? Gaven I wouldn't trust the results of trying to listen to these sounds on a standard PC. There is little chance that crappy PC speakers plugged into a standard cheap PC sound card and maybe connected to even cheaper earphones can reproduce pure tones at the higher frequencies - most all consumer audio equipment contain filters to remove higher frequencies which is generally interference from close by electromagnetic equipment - i'm not surprised most people can't hear the higher tones - the high pass filters would usually kick in at those frequencies. And this doesn't even take into account the fact that these samples have been compressed with mp3!!! Don't you know how this compression format works (DCT removing frequencies it assumes the listener will not hear)? What most people are hearing here at the higher frequencies are actually lower frequency overtones of the original higher frequency which are getting through the filters/crap speakers - do you notice as you go up the higher frequencies the next higher one suddenly sounds lower in pitch? - this is not the real frequncy you are hearing! The only way to do these frequency tests for real is using a proper tone-generator producing uncompressed realtime sound output which is rated from 10-25,000Hz. Siddles I have to agree with those who have mentioned the inaccuracy of this test due to the limitations of our PCs and speakers. The "23khz" and "25khz" tones both sounded a much lower pitch than the "24khz" on my system. "23" and "25" were quite comfortable to listen to (sounding a bit like the constant beepy noise which used to accompany the test card pic on telly - anyone else remember that?), whereas the "24" was a very high pitch which made my head hurt. "12" and "13" were indistinguishable from each other on my system, and "17" was the only one I couldn't hear. Since the threshhold of human hearing is normally taken to be about 20khz, an accurate test should find very few people able to hear anything higher. I know my left ear can hear very high-pitched noises, much to my annoyance, since some computer equipment emits constant very high whistling noises inaudible to most adults, but intensely irritating to me, and prolonged exposure hurts my head. Some people don't believe me when I tell them that bank cash card machines are actually quite loud! Btw I'm 32 years old. theo Could hear up to 16,000 at 51 years of age Name well that was annoying. I tried 14,000 thru 18,000 and heard all of them, but I couldn't hear 25,000. to be honest, I don't entirely get this. *dummy* ~a54~:) ow. 17 and can hear up to 23k hz. 15k makes me want to scream. THomas B. Deutschland im a 37 yr old male, i can hear up to 23,000 Someone Hey, in sample 1 do you notice somethhing in the tone? its in the background, i listened with headphones. it sounds like a person laughing then 3 strikes at a metal pole. I don't know what it is. anyone else hear? Guest I'm 17 and I could hear all of them. 16k hurt my ears horribly...it would definitely made me leave a store I heard it in...it gave me ringing in my ears and a headache. Person I'm 13, but I could hardly hear 17k, so I guess mine would be around 16k... :/ Jordan Hughes you might think you can hear 25 thousand but the thing is theirs distortion when you turn it up loud or you use a crappy stereo Ross Avery I can hear them all but 24,000-25,000 and I am 19. Scott i'm 16 n half and can hear all of them =] I'm 15. I can hear all of them but 18, 19, and 20. I can barely hear a very slight noise on number 17, but I do hear it sure enough. 25 is by far the strongest. [Teh Drama Llama] I got up to 19,000. ._. I'm 14, about to turn 15 in a month. john 42 Year Old Male...Clearly Hearing 23000...and can not hear 24000...And I always thought I had a problem hearing the spoken word. Don I am a robust 69 and can't hear a think on the test. Are you guys sure there is something there??? Knicksfan5588 I'm 18 and can hear 22,000HZ but not 23,000HZ and up. killired i'm 36 and could hear 21,000 but my dog was going NUTS when i played them!!!!! Nicholas Woodman Wow...that is a bit of a bummer! I just turned 31 and can only hear 12k. But at least my eyesight is good so I can still design cool wrist cameras for sports http://www.goprocamera.com :-) -- this sound site is more of what the internet should be...very interesting...THANKS OCHEN! Jim I'm a 52 year old male and have listened to a lot of loud music over the years and can hear up to and including the 21k. tictactoe I'm 27 and 20k was the last one i could hear. To make the test, use good headphones that can play these frequencies. Otherwise, you'll be hearing low frequency tones produced by distortion instead of the real tones. 17 year old dude i think the 25k one is stuffed. i mean i can hear all up until 24k,which i cant hear, but then i can hear the 25k recording. what the???!!! tom u sad fools i can hear the 25000hrz and im 69 Kristjan I'm 18 and on normal volume rate i hear all of em. andrea i can hear very well @18,000Hz; less well until 20,000Hz, nothing beyond that. i'm italian and i'm 23 :) Ashley Me & my mom did this & I could hear up to 20000, she could only hear up to 13000! ruby im 14, and i could only hear up to 18000. although i couldnt hear anything on the files above that, listening to them made my eyes water and hurt... Andrea I'm 24 and I can hear clearly till 20Khz! Chris I'm 48 & Up to 22000, I heard clearly. Guess that explains a lot. Right now my ears really hurt. Xanio I'am 25 years and up to 21000Hz. I'am Italian. nj Thanks! Now I know that the constant tone I hear when it's not too noisy is 12,000 hertz. pam carr I am a 48 year old, raised in the head-banging 70's and I heard them all. Talk about annoying. Worse than Boy George! rick 1m 13 and i herd them all 17 and18k reminded me of someone flat lining and sample a all i herad was background noise and kids laughin rick plus there all annoyin as hell i wouls=dnt go in that store TinaMarie I'm 42 and I could only hear up to 14,000. I didn't really think there was a sound when I first read about that and tried to listen to it. Thanks for clarifying! Tony I'm 17 and i can hear well @22,000Hz nothing above that. i'm italian Jenny I'm almost 31 and I can hear up to 25,000 Suzanne Denys Can anyone find a site for low tones? Now I'm interested to see how low I can hear. Barking Dog, Angry Baby I can hear up to 22,000 and am in my mid thirties. The 2nd sample noise woke my infant up instantly out of a sound sleep and she was two rooms away. This noise also got my neighbor's dog barking. What a great way to annoy dogs in your neighborhood. I think I'll blast this on my stereo the next time at midnight -J/K or not. David I'm 36 went to 15. my son is 11 and he went to 17. My 10 year old could hear 20 Elisa Io ho 22 anni e ho sentito fino a 24.000 Hz, quello successivo non l'ho assolutamente sentito. Sono comunque rumori assordanti... Pagly I can hear sound up to 24.000 Hz and I'm 18een years old! Judith Tinc 15 anys, escolto fins 20.000 hz. És un so horrible, peró la cosa és divertida. (I have 15 years old, 20.000 hz is my limit. is is a horrible sound, but is funny thing). Sergi I'm from Reus, Catalonia, Europe. My freqüence is 20.000 hz. Emma I just turned 17. I can't even hear the 16,000Hz And it's not like a frequent rock concerts, either. Lucky me, eh? dethstryke i'm 24 and i could hear 17000hz 18 and 19 and 20 were making my ears feel weird from pressure though! Emily I'm 16 and I can hear up to 22000hz, although I think my ears might still be bleeding from 16000hz. chaoticset 27, can hear only up to 20,000. However, I'm going to try it on my kick-ass headphones next (low volume, natch!) to see if my laptop's speakers just can't handle the sound. Annibale I'm 59 and I got some hearing trouble with my left ear. Nevertheless I can hear fine up to 24 and very weak 25. How strange! Am I anomalous? Maicol I'26 - and hear 18.000 Hz Mint I'm 26 and I can hear up to 17,000 very clearly.. can't hear 18,000 and up, but I did end up with an earache after trying over and over. Though I am on a laptop so my speakers are sketchy at best. Brian 26 - 19,000 SErgio I'm 32 and I hear until 17. 18 not very good steven I could only hear to 13000. i'm (31) Kal I think some of the sounds are broken. I couldn't hear 15000 but I could hear 25,000 clear as day. Mark I'm a 34 year old male and can hear all the audio files. Hmm, I guess I'm listening to the right music :) Mel Hi, I'm 37 yrs old and I could still hear 16KHz and the 2 initial samples you have from Steve. When I was 25 yrs old I could still hear 18KHz. GC I am 44 and can hear everything up to 21000. joey im 33 and could hear all the way to 22,000 but it was difficult....thanks for the test!! fredrik I hear cleary to 22.000 im 20 yers old..TO me it soun like a prank fredrik I hear all samples to fredrik I hear cleary to 22.000 im 20 yers old..TO me it soun like a prank...testing more..and now I hear a samll small sound att 24:ooo to Kal My mistake.I am retarded. I was a bit sleepy last night and did it with the air conditioner on and at a different computer.I tried it on a different computer and heard everyone. I don't think it matters how loud the sound is,you either hear it or you don't. David I think my computer must have messed them up or something, I could hear all of them but they seemed to get lower... :S Hans it takes headphones to hear 25 kHz an i had to crank up the volume from 21 kHz onward, which i usally have quite low. i'm 35 and i remember always having a whistle in my ears nobody else recognized when i was younger - can't say i miss it^^ Michael I'm 53 and believe I hear to 16k thru Bluesky studio monitors. Anything above may be imagination. Then again, crickets chirp away outside my window as I listen. Tom I'm 18 and I can't hear above 13 MHz. However, 17 MHz and above makes my head hurt. I guess it affect me even though I can't actually hear it. sean good site the sounds are good just like the mosquito ringtone Henk I got the same as Tom, I'm 15, I can hear it till 17.. But later my head hurts.. andy I'am and i can hear up to 17K.. Not very good i think.. Harry If i turn the speakers to max i can hear them all up to 22MHz but not 23 24 25 Harry and im 14 harry again ok tryed again and turned the PC volume up as well i can hear every one of them apart from 25 Omar Incredibile sto invecchiando, ho 30 anni e sento solo fino a 16000... Dustin I'm 35 and heard 20 just fine, but 21 was very faint and was more of a pulse, not the tone... Age has something to do with sound sensitivity, but so do genetics. Cool test, though - thanks for putting it together! Big Danny T I'm 34 and I heard up to 21000. After that, nothing. Heza How is it that I can hear up to 19, not 20-24, but hear 25? I'm 18 nadia i can hear up to 20,000 i'm 16. i think that's average^^ Leanne I can hear them all.. I think my ears are bleeding :P Andrew 1. I'm 53 and I can hear 17000 Herz perfectly well but I am unsure about 18000 Herz. 2. As I see it, there may be a strong correlation between age and the frequencies one can hear but the variability seems too wide to make a "reliable" device (i.e. one that just targets kids). 3. There is an ethical issue. Should kids and young children be given short shrift just because they can't help hearing this infernal whine? What about babies? They are hardly in a position to get away from the noise and their parents, if they are deaf to higher frequencies, would not be aware of the torture being inflicted on their young charges. 4. What does it do to dogs? 5. Does the device permanently damage hearing? 6. As I see it, the modern world is far too noisy anyway - we can all do without this silly device. 7. In any case, shopkeepers would do a lot better to befriend youngsters - after all, they are the consumers of the future. deeke I could hear both samples just fine. I am 26. I also could hear up to 23,000Hz, then i lost it. Very interesting. Andrea I'm 26 and a half, I could hear til 20 000 clearly, 21 000...nothing. Is that good? Mike http://www.aubraux.com/mosquito-ring-tones.php has some unique high frequency ringtones. Ms. Maladroit I'm 17 and I can only hear up to 16000 - 17000. Guess that's what those damn earplug/phones will do to you. Lindsay I'm 21 and I can hear them all if I turn my speakers way up. Well, all the ones I tried anyway...10,000 just about broke my eardrums! So I skipped the ones between 10,000 and 15,000. I could hear all the way up to 25,000 though. simone im 15 and i could hear most of them but my ears are ringing and they wont stop !!!!!!!!!!!!! H.E.L.P tai I heard all of it, up to 25,000. Well, 25,000 was a wee bit faint, but I heard it. I think using the sound to repel kids is sort of mean, but at the same time, I'm prolly gonna use a tone for my cell phone's ring tone, as it will be silent to my teachers, and the adults around me. I'm 13. It'd be great if you could put up even more frequencies... I'd love to hear what exactly my limit is. I'm still amazed I got 25,000, as I listen to my music quite loudly. On other frequencies... I got a docking station for my ipod for Winter Holidays, and there's a buzz on it.. It sounds just like 25,000 sound you have up. No one else in my house could hear it, and for a while, I really thought I was going crazy... Diane I am 40 years old and I can hear ALL of the tones loud and clear! :) xha1e im 20 and a competitive gamer so i am well tuned to sounds, i could pretty much sense the highest freq somewhat, i tried some of the lower ones that the elder people could not hear and holy shit my ears. i could see why it repels kids this shit HURTS Mark i heard kids were using this noise as a ringtone so that teachers can't hear it Spider I'm a drummer - and have been for more than 20 years. Can't hear past 14,000. Durrrr I wonder if there's a connection?? Dave I could hear all of them and I'm 17. That's cuz gods can hear frequencies in excess of 2Ghz. Dave I could hear all of them and I'm 17. That's cuz gods can hear frequencies in excess of 2Ghz. david richards hi i heard the ringtone in school so i decided i wanted it so i went online and found ur site i downloaded all the tones and i can hear them all in 12 by the way Adrian pinto I have 16 years old and listen all sounds. Michael I am 28, grew up on a farm, and have run a lot of equipment, but use hearing protection regularly. I could hear 20K clearly, and 21k faintly. Michael m i am 18.....and my ears are ringing....ouch.....adults can be evil, No? Lloyd Wabbitt Naw, thats just yer kneebone, buddy. Paulo Cabral I'm 53 and I can hear clearly 23000hz - Why ??? Boney Jenkins I'm 41 and I can hear that annoying 15,000 Hz tone just fine. I cannot hear the 16,000 Hz tone. Corey I'm 16 and I can hear up to 19,000 clearly and I can barely hear 20,000 and it makes my heaed hurt but when i tried the others they din'nt work. It sorta disappoints me because I'm curious. I think i may have a headace now. wj Ik vind t knap als je dit kan lezen!! Joe 31 years old. I can hear no problems up to 19000. I'm surprised because I play in a very loud rock 'n roll band daily with decibels up to 130. I thought for sure my hearing was damaged by now. chris i'm 17 years old and i can hear something faint at 24,000 but 25,000. i hear nothing Joe Im 14 and i can hear up to 18000 pheno i can hear everysingle sound very clearly, apart from 24,000 at which point i can hear someone thing encreibly quietly, i can hear 25000 like the pips radio 2 makes when it hits 8:00 lol Violinista i´m 38 old year,i can hear up to 20,wao is gret,rely. tengo 38 años,quiza porque sea musico logre oir algo en veinte,pero bien caida la noche y en conpleto silencio. Danny McKenzie hi all, i'm 52 and i can hear the 23 000 hz frequency. i know that there are young people out there who can barely hear the 17. i'm really happy my ears didn't get so old as i got. joe Miller Oh that's amazing if you look at danny, who's 52 and can hear the 23. I'm only 14, and always have headphones in my ears, and go to punk/metal concerts and can't hear the 16. I'm so upset..... :-( PS: i think i will not use this ringtone for my mobile...... uhh Rob I'm a 13 year old guitarist, and I can hear the whole range, 10KHz to 25KHz, along with both samples. Rob Sorry for the double post. Note: The second sample hurt. Rob (again) Correction: Mhz*** Stephanie I'm 18 & I could barely hear 20000. Nimoshi I could hear all of them at a medium volume. I could probably go higher. I can hear my Nintendo DS humming while its charging. I must have some kind of problem. brandon i can hear the 24000 very clearly... normaly human being can only hear about 20 till 20000 hertz but i can hear 24000 hertz isnt that crazy Cody I could hear up to 18000 very clearly, then on 19000 I had to turn it up, I couldn't hear above that. I'm using Sennheiser HD212Pro Headphones on a built in soundcard, so maybe the soundcard has to do with it. Eitherway - my ears hurt now. = Þ Nikolas Coukouma I posted a few entries (1, 2, 3) about the related ring tone story. The New York Times claimed that the ring tone was 17KHz, but it's the same 15KHz you mention. It's worth noting that most speakers and headphones don't reproduce frequencies higher thank 20KHz, and that's according to the packaging (I suspect they actually suck or fail completely there). Nikolas Coukouma Let's try the links again: http://nikolasco.livejournal.com/342858.html http://nikolasco.livejournal.com/343040.html http://nikolasco.livejournal.com/344545.html Bozy if we needed to create a song that with 18hz, how can i do it??? Stetson i can hear 24 but i can also hear 25 but its not as loud as 24 im 14 Sherilyn Hi, I'm 42, and I can hear up to and including 22 with the exception of 15. I'm not sure why, it happened on another site with tones as well. Just can't hear the 15 range. shannY wo0o 17000Hz Ferry every body hears the 14 until the 18000Khz(my phone cant handle it) i think it dont wordks *.* I'm 13 and I could just barely hear the 25,000. crazy. -------------------------------------------------------------------------------- Boy It is true, I beleive you only filtered the harmonics on the 24 because it is the only one I can't hear clearly (however, can barely hear it). Boy Edit: I can't hear the 24, that must be the computer. Boy Well, it may be just the speekers, but even my old family can hear the 25 clearly, even my grandfather. Nick I heard all of them except 24k. I heard 25k but not 24k...weird. 28 years old. chonwaen I believe that the people who hear the 25k are actually mostly hearing a 12.5k harmonic. My threshold of reliable hearing was 15k (im 33) and the gal in the cubie next to me had a threshold of 17k (she's 20) Chi Im 35 and could hear 22k Alicia I am almost 47 and had easily heard 20K. I tried to go higher but the bites wouldn't load. I guess all the loud music in the 70s did'nt ruin my hearing totally. Frank 53 years old and I could hear up to 21,000Mhz giles im 90 and i can hear them all kitznegari i could hear them all until itunes refused to play them after 20k! Sophie I'm 13 and hurd 17 very well, but I could hear nothing after that Boy Use the flash one, no offence, but this version is not 100% accurate. Lautreamont Funny test. Is it reliable? Michael I could hear upto 21'000 very clearly but I don't think my speakers could handle past that because I went from clear to nothing at all. Oh well, guess I need better speakers :P Nick I'm 16, and I could hear up to 25000, although it was rather weakly. Um, yay? Agnes Whoa.. I can hear the entire range =) mike uhm im 14 going to 15 i barely listen to loud music i can only hear up to 19 and 18 when speakers r at max and at max ther fn loud James Kelli Dudes/Dudets :P we are all testing at diffrent loudness the higheer the speaker is the more u hear the less the less u hear thats y some hear all and none hear any xD wtf, i hate these commercial shits, casino and online poke is just bullshit anyway anyhow, lot of fun, am 17 and could rely make out 19 and not 20, but then my ears were never that exceptional ^_^ Sam I'm Twelve and can faintly hear 22,000 and 23,000 and I can hear 21,000 easily. Bunggo What? Ana hahaha it is great just surfing the net and i found the different frequences, and well i turned my speakers almost to their lower level ( the volume control in windows in the last line ) and i could still hear them all. and well i'm 19-20 Antonio I am 29 years old and I can hear all. I think this is a lie Nemesis Where can i get more sounds?? Codehaven 18000 is the highest tone i can hear. Still pretty good for an 18year old. pharmtard 28 yo male. I hear all and had a co-worker (55) listen. She also heard them all, so I am wondering if this is a hox or something? Greg > Las Vegas I can hear every single one of them... 10,000 - 21,000 are loud as hell 22,000 i can bearly hear but i can definatly feel pressure in my head... 23,000 and 24,000 i can hear clearly + head pressure... 25,000 i can hear faintly but my speakers start sound like shattering glass... alot... I thought humans can only hear below 20,000??? Greg > Las Vegas Oh yeah and im 20... and a half booya ;) Patrick I'm 22, and am using a set of Audio Technica ATHm40FS headphones that are rated at 5/28,000 hz, through a headphone preamp rated at 10/150,000 (Behringer Microamp, I think). I can't hear anything above 13 KHZ, but I do actually have an excuse. It's called Norie's syndrome, and it's rather annoying, but not quite as annoying as hearing yourself through a microphone out of phase with yourself on both chanels. It tends to make you want to compress your head. I tested myself using sign waves at 96 KHZ, through my Delta audiophile 24/96 soundcard. When I was little, I used to hear all those oscilating CRT's in TV's and monitors, and people thuoght I was crazy. One day, my parent's 25-inch Magnavox TV decided to start becoming really loud and scary. I told them that the tube would die, and they didn't listen. A week later, they suddenly have no more picture. What do ya know? There was another instance where one of the TV's was hit by a bit of a power serge, and the relay that kills power to the CRT went and shot itself. Thus, when they turned off the TV, although there was no sound or picture, the stupid tube was still oscilating. They thought that since everything was still working that there was no problem with the TV, but of course that wasn't the case at all. Now, was it? Thanks to Mr. and Mrs. Norie, whoever they are, I'm on the road to a progressive hearing loss. There are certain things that are quite annoying about this, especially since I'm big into audio production (though I don't do it as a profession or anything), but one thing I don't miss is hearing those stupid CRT's. Nope, don't miss that one bit. And for those of you who can still hear those, just be glad that flat panel LCD and TFT screens don't do that sort of thing. shorto just turned 18 and i can hear 25,000 Hz just fine :D chelsea and sarah i'm 16 and i can hear the 15,000 one but my 16year old friend can here the 18,000 but i wouldn't that as a ringtone though i am going to get a joke out of setting it off it class haha IT WAS FUN Joan Pons From my point of view, these are not valid sounds. You have published MP3 files, that mixes different frequencies from 15k to 22k. Open yor freq analyzer, and you will see. Rergars,s J. Jyu Well, i could not hear beyond 15000. And then i used the graphic equalizer in Windows Media Player and turned up the 16KHz range to max. After that I could hear all the way upto 25000 except 24000! So, its weird. Hard to test with standard laptop hardware and media players i think. edgar 32, drummer, only thing I hear are the voices in my head...and 17,000 James I could hear all of them also, but like what sean said I think after a certain point I'm only hearing the harmonic of it. The 20,000hz was the hardest for me to hear, but I could hear something fine all the way up to 25,000. Maybe that's where I could no longer hear the actual note, but just the harmonic Giga i'm 15 and i could hear them all steven i'm 18 and i can clearly hear 21000hz Marco I'm 29 and i can hear at 17000 hz John I can hear all of them except the 24,000Hz,but i can hear all before and 25,000Hz after.They are kind of annoying type sound though,aren't they? John again Woops,sorry,i forget to give my age,i am 35. Hobbes 42 years old and I can hear up to 15,000 Hz. If I turn the volume up all the way, I can bearly hear 16 kHz for a brief moment. Hmmm. Rugace more than 17kHz is silence for me....I'm 26 years old man. Felix more than 15kHz is silence for me an i am 17 years old maybe its why i am a musician Fientje Ooops.. I'm 15 and can't hear 19000 anymore, that's not good is it? Mat It's interesting. I'm 18 I can hear 20,000 well. Everything above that sounds like a hum, except for 25,000, which I can hear. I've always thought that I've been damaging my ears from headphones and concerts, but apparently not yet. Diarmaid I'm 22, I can hear 14kHz, and from 15 to about 19 I can sort of feel a pressure in my sinuses, and a slight ringing in my ears. Above that, I get almost nothing. Maybe a mild discomfort. Eugen I can hear anything . What"s about this game?? Even now I D"ont hear my mom screming Stupid game Ps I fogot to tell I"m death bigpissup Im 26 and can hear up to 21kHz My Mum can here up to 18kHz My Dad up to 12kHz Jennifer It's sad, but I can only hear up to 14,000 Hz and I'm 23 (24 in November). ;_; Im 18 and can hear up to 25kHz My Mum (58) can hear up to 24kHz My Dad (59) can hear up to 25Khz Thorlius 19yo male, with average hearing - I can hear 19KHz fine, but at 20KHz, I can just barely pick it up with my right ear (if I turn my head sideways), but nothing in the left. John I get a "Forbidden" error when I try to listen to most of these. tutash Hearing loss in my right ear limits hight frequencies to ~4KHz when volume starts to drop off. In my left ear, I get to about 14KHz before volume drops out the tone. I'm 36. Brian I'm a 32-year-old male and I can hear the 18k sound with no problems. Greg I'm 33, and can hear both sounds. The first one is a bit more faint, but it's there. As for the samples, I can get up to about 18000 and then it totally goes away. And that's wearing a headset and cranking the volume al the way up. And 11,000 was really painful on the ears. Ouch. nick im 15 and i max at about 23000 and 21000 with a headset and 17000 on my phone Jenna I can hear them all... I'm 19... and they all sound perfect to me... I dont get it... Dan I can hear them all really loudly, I am 25. The ones in the 20,000-25,000 seem to sound deeper. Julia im 18 and almost 2 months.. i got to 19000 but that was it..is that bad for my age? achk! Ritesh Khadgaray 24, and able to hear all the sample from 10khz to 25khz. using philips shp805 headphone, with frequency range of 10 - 28 000 Hz. Stefi Ondikova This test is very interesting. I can hear clearly 17 000 and I'm 24 year old. I guess I'm getting deaf at early age :) Matthew Smith I'm 33 - 17K was my limit. Alex 39 years old and can hear 24,000 hz I can't believe that people younger than me can't hear more than 15/17,000Hz!!!! Kathryn Owww! I'm 51 and wear earplugs to sleep. Sinusitis interferes sometimes but today I heard up to and including 23,000khz. Which reminds me... must change (Dell) computer fan to a quieter one... hard to hear tones over the fan's noise. Thanks for the hearing challenge! Agent.Why Huh. I've been wondering if I have somesort of hearing problem on and off since I was 9 or 10. I'm now 26 and I have trouble grasping all the words of some people. I found that I can hear all the way up to 24000MHz, but there are definitely a few gaps on my way up there. Wonder if that can explain it? It could also be that I'm very absentminded as well, I suppose. Ryan I'm a few weeks shy of 27... Through the speakers, I can just barely hear 18K, but nothing above it. With headphones, I can hear 18K clearly, and just barely hear 19 and 20K Al 38, could hear the 16,000 Hz sample. ns 58 years old..... could hear 12 but not 13 ashli as a 22 yr. old female, i was able to hear up to 19,000 Hz. not too shabby. Dave I'm 31. Can hear up to 22000, but just barely in one ear. Antonio Miguel I can hear up to 21000 and I'm 18,is it ok??Normal, bad, good???:s ronnie I'm 25, and I can hear up to 21,000 quite clearly but not 22,000 or higher at all. Luke The little static pop when the file starts and ends makes me think I'm hearing the higher sounds, but I think it's wishful hearing. But at least now I know that the persistent ringing in my ears is somewhere around 19K. Christelle 23 years old, can hear until 25. My friend, 24, can hear until 25 too! James I can hear clearly up to 20,000 Hz at 21,000 I can barely hear maybe something but it would be easily ignored. I'm 31 yrs old and have always been able to hear alot of things. I was able to hear when someone turned on a muted TV in another room; just by the buzz. Not so much any more. Norellicus Keep in mind that it may not be your ears failing, so much as your audio hardware being physically incapable of playing anything over a certain range. My headphones are rated to 20k, but I can only hear up to the 19k tone on them; but I can hear all the way up to the 24k tone when playing through my 5.1 stereo. Brandt I'm 41 with 26+ years in and out of rock bands. I could hear 15K, but not 16K through the PC speakers. I could only get up to 14K with headphones on. It might be interesting to try with better sound equipment than my computer... Jon I couldn't hear 16 and 17, but I could hear 18, and 19. Then from 20 onwards I couldn't hear anything. Strange. asher Holy crap this page is long. Airick I'm 24 and I can hear only up to 17. Granted, I listen to music at varying volumes and genres (classical to drum 'n' bass), but this concerns me actually. However, I figure once you destroy your hearing, whatever strength was damaged, it's gone permanently (it's like a GPA, it can only get lower). scott wow, i feel like such a 'youngin', I'm 17 years old and can hear all the way to 23khz, may have something to do with my highend studio headphones though... conny I am almost 52 and i can hear 15,000 Hz but not much more. I have tinnitus that is almost like the sound of 15,000 HZ. When i played the other sounds up until 20,000 i felt ill (in my chest and in my stomach) and i now have a slight headache. Am convinced that noise pollution , also that which we cannot hear, does make us ill. bill i'm 45 and i'm an boring saddo. What the heck guys, stop being such ole' bitties on the ear range thing and discuss if this is even an actual test. This fellow is having us for a laugh and just taking the piss. Although i am excited that lifehacker.com and internationalcomposting.com sent me here dan i can hear 17k but i think the actual limitation is my speaker system rather than my ears. i will try on some studio headphones. Snit I just happened to have had my hearing tested - it was free and I figured why not. I *know* my hearing is very, very good - especially in the high pitch ranges. With that said, I could not hear the pitches past 17,000 or so. I am guessing it is from my lousy speakers. Tim i can hear 10k fine, im 29 year old adpd 25 years young, male. I can hear 21,000 Hz perfectly. Don't hear a thing at 22,000 Hz. Using headphones to listen to the samples, btw. Katie I'm 13 years old, and I can hear 21 easily, but 22 with difficulty. That's really cool =] Katie Again ! I just tryed to hear 25 again, because I was surprised I couldn't hear it. So I stopped fidgeting and really concentrated, and I heard it quite easily. Maybe, I have good hearing after-all. dunno I am 28 years, pushing 29. I can hear 20khz loud and clear but after that nada. I don't understand how it can go from totally audible to nothing just by lowering it by 1khz. Gabe WOw! & Ouch! I just turned 28 with the speakers/headphones at my usual level I could hear up to 21, 22 something was there.. but I couldn't pick it out as noise... well then I cranked my volume up all the way with headphones on... I could here everything except 24, 25 is loud and clear! Then I stupidly tried 10k again.. I'm not unsure if I could here any of them... my left ear is now throbbing.. And I feel like an idiot... and now I'm happy I've been learning sign language... Xswords I can hear up to 25000 hz without a problem. Cat I'm 22 & I could hear up to 20,000, but up to 22,000 made me uncomfortable, though I couldn't discernibly hear them. Dave J This is interesting. I can hear 18k and 20k but not 19k. Maybe speaker harmonic? Anyway, everything above 20k is silent, but I'm at work with the air conditioning on, so who knows. Sean Dudley 33, hear up to 15,000 Hz Sean Dudley 33, hear up to 15,000 Hz Sean Dudley I just tried again, this time with headphones, and I can hear all the way to 25,000 hz with headphones. :) 33 years old Sean Dudley Oops.. I meant up to 20,000 above. I can hear up to 20,000 Hz through speakers, up to 25,000 Hz through headphones. Up to 23,000 Hz through headphone easily. David damn.....speakers or headphones.. I can only hear 12.000. To much noise at work I guess and im only 31. John Boy-14 Great stuff, but you can make your own modulated tones like the Mosquito to give people instant-headaches. Albert i can hear all of them except the ast on eits really faint you have to pay attention to hear it im 17 chris im 15, male and i can hear 20k Thom male, 19, can hear up to 22000 clearly, but just clicks above that. coincidently, i've failed every hearing test i've ever taken. jami 31, female; i could hear screeching up to 13,000 and then from 21,000 on. from 14,000 to 20,000 i could hear the files begin and end, but no screeching. it was the same for my 27-year-old boyfriend. i like-a the rock music, but since the boy and i don't have the exact same genes and haven't been to the exact same concerts, i suspect the doctors and audiophiles are right -- this is a test of one's laptop speakers more than one's ears. Q I'm 23 and the last I could hear was 16,000. 17,000 made me feel uncomfortable but that was it. R 27 male can hear up to 17k I go to clubs a lot... suprised it's not worse. Randy 36 male and can hear up to the 25k through headphones. Some better than others. The mosquito samples did give me a bit of a sinus headache while they were playing. Sany 17, female, and can hear up to 24k. OUCH for the sample 2! My A Age:32.5 Female, Left ear can hear up through 19k, right up through 20k. L Age: 44, Female. I can hear up to 20k, but links to 21k-25k are broken today, so maybe I could hear even higher? viipul 17K, 26, male Jesse 14 kHz for me (27, Male) Diabolical! ...Though I can perfectly understand why store owners would want to install these in their parking lots. Jason I can hear all the way to 24,000 myself. And I'm 30! Jason I can hear all the way to 24,000 myself. And I'm 30! Andy i can hear all using the computer but when i put them in to my mobile phone i can oni hear until 16000.i am 23 yrs old Ross I'm 24 and could hear the sound perfectly (in both mp3s). There's a monitor in our office which makes the most annoying, pulsing, high-pitched sound when it's on standby, and it seems I'm the only person in the office who can hear it. Ross Oh, and I can hear up to 22,000 Hz of the others. Lenny I'm 15, but I couldn't even hear the 16,000Hz one. Gin I could hear up to twenty thousand (I'm 17)quite easily. Then your links broke. *tear*. Interesting concept though, you've made my nose hurt. sara I'm 38 and oould here it at 10. They all sound the same to me. Ville Thank God I don't have to hear above 15kHz :) Kebin I am 31 male. I can hear both samples although the second sample REALLY gives me a headache. I can hear upto 25K Hz through my crappy speakers. :-) quixote 55 and I could hear all of them. Is there something wrong with the files? I ask, because they didn't sound like pure tones but more like weird radio noises from the good old days. Maybe what I was hearing was background noise of some kind and not the actual tones. Kate I can hear up through 17000. 18000 made my ears hurt but I couldn't really hear anything until I turned the volume up to about 30dB. I had to turn 19000 up to about 45 in order to hear it. I couldn't hear 20000...I experienced it as pain at about 70dB. I'm 20. Ryan 14 - 21k :D anoninerd I'm 55, and 17 Khz comes through loud and clear. 18 KHz and up, nothing. bartjeuh! 18-23k, beyond that, nothing :( bartjeuh! 18-23k, beyond that, nothing :( anoninerd I'm 55, and 17 Khz comes through loud and clear. 18 KHz and up, nothing. kevin music student everything about the 20000 the sound file is now broken i can year the 20 esily and clearly i could probably ident ify the pich but that would i take a while cuz i would have to go down octaves in my head Virus I'm 18 and i can hear at a limit of 22000 Khz Sandman I don't like posting a comment if it is longer than the article, but I feel there are some good points further down. I know it is all for fun, but as I read through the comments I got the impression people were disappointed by their results. The accuracy of these tests is massively influenced by the volume and quality of your speakers and the compression format. A 90 year old gentleman would be able to hear the tones... If you played them on high enough quality speakers that could handle the amount of power that would be required. He would hear them and everyone else would be permanently deaf. As to the compression format... The core concept of mp3 compression is to heuristically determine which parts of the source data (song, etc) is not audible to most humans... and the filter it out. Personally I have shoddy hearing. I'm qualified and currently working as a programmer, but when I couldn't find work I worked as a bouncer in the concert industry. When you're standing between a bank of speakers and the 90 000 screaming people they are designed to satisfy, you gain a whole new respect for those little yellow earplugs. When you are exposed to music at such high volume you quickly become aware of the impact it has on your body. It is not well defined what positive and negative effects can be caused by exposing parts of the body to various sonic frequencies. In numerous comments people mentioned feeling discomfort from these generated tones. Many of them despite not being able to hear them. I shudder to think what side effects the noise pollution from those shopkeepers could have on people that don't know they are being exposed to it. What effect could it have on a foetus carried by a mother who is incapable of hearing the incessant screeching. Her body wouldn't offer much protection. An unborn exposed to such a tone for nine months, with absolutely no way of altering its volume or location, the entire time incapable of understanding what's causing the pain. It really doesn't strike me as a solid foundation for a balanced individual. This is merely speculation as I unfortunately don't have the time to do the research at the moment. I'd be interested in any thoughts on this. Until the Tinned Meat Industry finds it the address I've given will work. ;) Sandman Dino I am 28 and I cannot hear anything above 13000 Hz. Richard I am 24 and I can hear up to 24 KHz. CaptainObvious This is an extremely flawed test, specifically in the lack of a controlled environment to perform the test. Ignoring background noise (air conditioning, computer fan noise, flyback-transformer noise from your computer monitor), the frequency-range of the speakers/headphones you're using, and calibrating the actual sound-pressure levels generated by the speakers/headphones means that this test is not accurate in any meaningful way. Sorry to be such a negative, but if you're that interested in your hearing, get a referral from your HMO and see an actual audiologist. It only takes about fifteen minutes. Cheers. Joseva Hello, my wife and me are 29 years old and we can hear until 17000 cps. What a dangerous way to measure your youth. It can be so satisfactory as devastating for your morale. Maciek It is simply not true that people under 20/ 25 can't hear the higher frequences. As we can see a lot of people can hear them (I'm 27 and can hear everything). WHy do some people give this magical 20 / 25 age limit? It is misterious and unscientific.... ??? im 16 and i can hear 25,000 hertz VaginaTron I can hear them all suckaz (I'm 25) 25000 isn't easy though; that's probably about my limit. Bianca I'm 13 and stopped hearing it at 17,000, my Mum and Dad stopped hearing it by 14,000 Daniel Rhodes 26 heard everything up to 23,000 Wayne Yap 20 Heard everyone of them except the 25,000 one.... not as loud as the others.... reeli faint ...i can barely hear it.... does that count? Jessica Im 14 and i can't hear 16 i can hear up to 15 and the nothing freaky Gonzalo I'm 18 but I can hear all the frequencys, why??? Scott I'm 13 years old and I can only go up to 16000... Matt Im 16 and i cant hear any of them Lowell At age 66, even avoiding loud music most of the time during my life, I can only hear up to the 13khz. josh 14, almost 15, and I can here up to about 18,000. Beyond that its virtually nothing unless I turn my speakers way up. (Harmonics, maybe?) Josh Julie I couldn't hear any of them! I teach and school nurses have tested my hearing and say mine is fine. I guess I know what the problem is! feebs I'm only 23 and I could barely hear 12,000 :( Anything below it though was horribly deafening...I felt sick from it! Yvonne I'm 52 years old - I can hear the 17,000 one. My kids always hated my hearing, - my son said I could hear a molucle fall in Japan (live is California) Ed 43yrs old and could hear it upto 21,000... Jim This test is highly volume and hardware dependant (sound board, headphones or speaker ... etc.) More so than you're ability to hear. I tried it on one of my machines with speakers and couldn't hear above 11,000. On another machine at max. gain and using headphones rated at 20,000 Hz max. my limit was 20,000. ken I can hear 13K and below. 45years Frank I just turned 34 and I can hear up too 21,000 fine. Although I can still "feel" the vibrations at 22,000 in my ears I couldn't report that I could describe the sound like the others if I were tested in a blind test. It is hard to explain but I know there is something different in the air (call it pressure) but it is not that I heard anything. At aroung 24,000 this "feeling" goes away and I can say that I hear and feel nothing. richard alderson my willy started to tingle w Joe Becher At age 28 my hearing stops at 17K. I heard 18K click on in my speakers, but didn't actually hear anything, just the start and end. I can hear both samples, but I'm pretty sure they are messing with my head. When I first checked the page I heard sample one as a chattering. Now, after playing with the range I can only hear sample one after I play sample two and that's a very short burst. Clair 50, can't hear anything above 14000. Live with Mother who is very hard of hearing. I've been noticing my hearing going since she moved in. Wow, very discouraging... cms is it ok if i put my speakers on max to hear the higher frequencies..? oh and i can hear up to 18000 hz ok sometimes 19000hz im 15 Steevo 24K I can hear some, and from there down it is a pierceing annoying scream. 26 and been bumping 12's for years. kyle i want to download 18,000 hz sound wave plz Matty 16 and can only hear up to 18! cray my mom(41) hear all of these sounds me(16) too 작은인장 I'm 33... I'm hear 22000Hz.... so funny..^^ Alison hey yeah this is awesome. im 14 and i can hear up to 18000. My mum can only hear up to 12000 lol. xx foxy im only 18 and cant hear past 14000 i need to get my ears checked Roy... Hi, I'm 60 and can hear 20000Hz very clearly. Sol I am a 39 years old woman I heard clearly up to 14,000Hz Olly I am a 36 year old man who has obviously done some bad things. I can't hear above 14K. I will use this on my students in class. Thanks Luke Hey i'm 17 I can cleaqrly here all of them. Had to swap speakers to do this though because 2 sets of my speakers wouldnt go above 20000hz. My thrid set struggled at 23000hz even though i could still here the 25000hz. Now im gonna test my dad cause he is always calling me an idiot when i complain about hissing sounds from monitors and the surround. cms hey again uhmmm can u tell ma wat software u used for the frequency analysis and if its free? i have one but urs looks kooler lolz its uhm nch wave pad it has frequencyanlysis ting that came withit and also have a frequency tone generator from the same nch ppl it can go from 1hz to up until what humans can hear (20hz-22khz) ppl who can hear that 25 khz (25000hz) sound hmm ur speakers must be messed up or something or u must have some real fn loudspeakers to hear dat lolz Mel I am 29 and I couldn't hear the noise above 14000, but when i played the 15 and above I just felt nauseous until I turned it off. I do have a cold though and my head is pretty stuffed up right now so maybe that is why I couldn't hear it? Aero I am a 22-year-old man, I could hear 24000 Hz that is obvious for me. But 25000 Hz is becoming very little to notice. Does my speaker influence the sound I hear? cms hearing those high frequency sounds depends on how good quality ur speakers are too . most speakers are limited to (20 hz to 20,000hz)escpecially normal computer speakers etc.. cms sry double post lolz Vince I think the most important factor is the speakers you are playing the sound through, i have been an audio engineer for many years now and learnt quite a bit about sound. most people probably have the capability to hear most of the frequencies but not through the speakers they are playing them on. Simple example, my teac home stereo has trouble playing anything above the 17-18 k mark clearly, whereas my senheiser mixing head phones can play upto the 20 k mark clear as day , all depends on your system, full stop. Zach Wow, I must have terrible hearing. I'm 18 and the highest I could hear was 15,000. leticoz im 14 can hear everything....well up to 20000 clearly but the rest not so clear... andy b i can hear upto 20000 just, but these sounds r amazing for annoying my classmates cos the teacher cant hear them but everybody else can... XD Szift well I'm 21 and I can hear from 10k to 16k and then from 19k to 25k - strange hole inside ;] though it may be caused by my speakers zach i'm 14 and i can hear all of them, but now i have a headache and i feel sorta sick dante I'm 15 and I could hear up to 20.000 Poss I dont think the mp3 format is very good for these sounds im 22 and can hear 20.000 but using a tone generator i could just hear 17.000 maybe mp3 being a compressed format has to much noise plus i would think the quality and type of speakers you use at home would make some differnts. Mister Mustard I am 39 and have tinnitus right at the limit of my hearing, which I now know to be somewhere between 14 to 15kHz. I seem to recall these noises coming and going all my life. A serious health issue, it turns out. Looks like I will be going to see the ENT with my results ... slowdown I am a youngin' at 18. I can hear up to 23,000, but 24 and 25 kHz is silent to me. Lutarez I can hear both samples & 25KHz A-OK, but for some reason, Winamp registers the first sample at 256kbps & 44KHz, second sample at 192kbps & 48KHz, & the 25KHz at 1536kbps & 96KHz. Mind you, I am 18, running a 3.0GHz Dual-core P4 with a ASUS P4P800SE with Windows 2000, a 7.1 channel sound card and 7.1 channel Zalman headphones (which double as external sound-killers when playing audio/video.). Raptor Dont now about you guys but i can hear clearly to 20000 and i have my speakers on the lowest possible point but i cant play the 21000 to 25000 dont now i think because its wav and i cant play it in power dvd media player bsp player dont now but the sound are clear very i can tell that i could hear all to the 20000 but for others cant say because i cant play it any idea post me :D Tyler Im 15I can hear them all pretty clearly Rick 17 years old I hear up to 25.000 hz Or there must be something wrong with the files :S salvatore He escuchado todos los sonidos desde 10000 a 25000 Hz ...lo unico casi imperceptible es el sonido del mosquito , pero si se nota una molestia al oido. Quiero decir tambien que soy DJ y Sonidista desde los 11 años...ahora tengo 34. trees rox! cool site i am 13 and i can up to 23,000 Hz trees rox! me again....^_^ i wrote it wrong... I am 13 and i can hear* up 2 23,000 Hz...I hope dats a gud thing... My ears r not da best...i play a classical instrument and music is always next 2 my ears!..lol Linuxrox I'm 26 and I have absolute pitch. With headphones I can hear from 10khz to 23khz. 18khz-20khz is really low, but I can hear. 23khz-25khz sounds good. With the computer speaker I can hear all of 'em. I could hear the other two sounds presented too. Alana The first two times I listened, I could hear up to 21,000 Hertz. Then I couldn't even hear 10,000 Hertz. Now I can barely hear 11,000. I'm 12 years old. What is going on? prence You're going deaf little girl. prence Oh yeah, I'm 22 and I can only hear 16k. I tried 17 and it gave me a headache and made my teeth feel weird :\ Skuf_2 20000Hz can I hear Ezet I could easily hear all of them upto 25khz. 'am 17. Bek i'm 18 and i could hear clearly as far as 20,000Hz, nothing but vagueness from then on until 25,000Hz, which i could hear easily.....whats up with that? this will be fun to test on my dad (60), he applied to become a bus driver but failed the hearing test because he didnt pick up on the high pitched noises. will be interesting to see what his threshold is, i'm guessing 11,000Hz at most =) Tom I am 31 and can hear only up to 16kHz but I believe the reason is crapy 1$ headphones I use. benn im 46 and i can hear 23,000 clearly with or without headphones Æon Lightbringer I could hear all the way up to 22, but then I didn't turn up the speakers very loud... I might have been able to hear them all, but I'm happy that I could get so high... another girl here in the office couldn't hear anything above 11, so that was kinda neat. I have to say, though, I'd probably have to murder someone if they tried to torture me with 19kHz, because that specific frequency was making my teeth hurt like I was chewing on aluminum foil! I con't think I could stand that frequency for more than a couple of seconds! veco i could barely hear the 25000 but then turned off the equilizer on my comp and ii could hear it loud and clear and annoying.... all the span... 27 yrs Greg I am 31 and could hear 14 no problem at low volume with roll off through 17 (had to increase volume to hear 17). 18 and up were inaudible to me. They just felt like they pierced my skull if the volume was up. Now I am a depressed audiophile. :-) dori O MI GOSH Sample 1 slowed downn was ear precing i have to let other ppl heare it Greg I am 31 and could hear 14 no problem at low volume with roll off through 17 (had to increase volume to hear 17). 18 and up were inaudible to me. They just felt like they pierced my skull if the volume was up. Now I am a depressed audiophile. :-) Patrick I'm 15 and I can hear the 25khz very faintly but am unable to hear the 22khz at all. 5 minutes ago my bro (age 13) could hear the 25khz but when he tried again just now, he couldn't. hotblooded I'm 55 and been in bands for 40+ years and have a slight Tinnitus in my left ear. I am using a medium priced Labtec stereo headset. I can hear all tones (most very loudly) except the 23kz and the 25kz..a bit oddly i can hear the one in between the 24kz..maybe being a bass player for so many years I should be listening to the sub frequency tests where i bet i would fail. very interesting. thankyou. yq wth im oni 15 but can oni hear up to 15 000hz Henry I am 9 and I can hear up to 24. Interested I'm a female age 31. I couldn't hear 23 KHz. Goth Master Sweet im 16 n i can hear 23kHz. Ive been blasting 70 dB heavy metal in my ears for the last 2 years. ~SWEET~ Ouch I'm 17 and could hear all of them. My vision started to blur for 24,000 and 25,000. What's the deal with that? Hawk Some of the tones after 1800 kHz have a low buzzing which interferes with the tone Cathy I'm 46 and heard them all loud & clear Lauren Im Lauren and im 14 and i can hear all of them until i get to 22. I dont think anyone can hear further than that, maybe you can hear the vibrating of your speakers... the highest one no one should be able to hear anyway. eason oh my god! i'm 30y ,15,000 Hz Han-Lin I'm 17 and the maximum frequency I can hear from this site is 20,000 Hz when I turned the volume to about 1 third on my Dell speakers(Model No. A215) and up to 25,000 Hz on maximum volume. ollie im 14, nd can hear all of them.... 25,000 better than 20,000 acually... weird Bob some things i've figured out is that with the these sounds, some times adults think they can hear them when they aren't hearing the actually high pitched tone. if you turn the speakers up too loud, then you can hear other little background tones that they believe is the tone. but that was with my parents and they're in their 50s. i can hear the 25,000 Hz at half volume on dell speakers Arjen Yes! 23000! Koen I Am 22 years old, and I can hear all of them... No problem, even the 25.000 Hz. I wonder if it's due to my stereo system... sme 36F with tinnitus that rings at about 12kHz loudly in both ears which is hereditary. I can hear all of the samples with $10 headphones and my sound card turned lower than what I would play music, a DVD or a PC game. 18k and 19k are softer sounding, but cause physical dis-ease starting about that point up. As a reference I had my ears checked due to my tinnitus about 5 weeks ago and the doctor actually used the term "wonder woman hearing" when reviewing the audio test which included hearing range in Hz as part of the test. Dorus I am almost 23 years old, and I can hear up to 14K, I don't hear 15K.. I guess that's not very normal, and that could be right. I am guitarist in a rockband, and now I am definitely convinced that playing guitar really causes hearing damage... I just hate these protection plugs.. Michel from the Netherlands Just went 38 years old, having tinnitus for about 10 years now. I could hear the sound up to 15.000Hz with €399,00 Sennheiser HD650 headphones in standard PC soundcard, could hear 16.000 Hz but on higher volume (not too high!) but sound is very far away. My tinnitus frequency is probably around 16- 17.000Hz, so I found out thanks to this site. Can you produce anti-sound to reverse my tinnitus? ;-)) Karen Didnt hear 2nd one at all but was able to hear all the way to 20,000 and I'm one week shy of 50 gbst 60 years young and I hear them all. set my false teth on edge, but as clear as a bell. Drs.Brakovich I am 37 years and i did hear the 15K noise.16K did nothing to me. But i am from the Netherlands,does that make a difference? :) harley i'm 12 years old and i could here them all Tom I hear them all rob 35y/o male- I can hear clearly to 19k, 20k is lower but discernable, and can feel a "pressure" to 22k. rob rob again- added note: the frequency response of my headphines is down 3db @ 21k, so it may be limitation to the test. Jason Why not ZIP all files into a single download, would make it more worthwhile to try. Kharaa 16 year old male.. could hear each sound just fine. None of them hurt my ears, either. Perhaps too many years of sitting in front of a pair of resonating monitors... Dan I can hear up to 22,000 but cannot hear 23...mmm I am 46 years old. my ears are still bleeding after I pressed 10,000..man that is annoying. max i am 16 but i can't hear any noise!!! including 10,000Hz MAX so strange when finished to hear 18000, after that my mum & i also can hear all of it up 2 25000Hz ,,,maybe it is da problem of sound device nathan riehl I'm 16 and a musician and singer, and I heard the 25,000hz Uchawi I am 45 with one ear at about 50%. My range was up to 17,000hz on the good ear and 13,000 on the weak one. Two co-workers with no loss; one 55 and the other 22 were 14,000 and 18,000 respectively. Heather I'm 27 and I can hear up until 23K!! Makes me feel young! Chris 14, almost 15 I can hear the 24000 easily and have to turn the volume up a bit to hear the 25000, personally I find the 23000 was the most annoying. Amanda I'm 16, and I heard all of them... though 22 and 23k were slightly hard to hear, the rest were loud and clear (unfortunately). Wolf I'm 42 and could hear 20k without trouble. 21k was almost audible. JoeGee I am 40 and can hear everything up to 23,000 khz, if there aren't harmonics in the samples. Mike I am 13, me and all my friends at school can hear them all Richard I'm 29, and can hear the 25,000 sample and downwards. Whats wrong with me ROFLMAO! Mr Mike Well, at 58, that sure explains lots of things... can not hear above 13,000 Hz! Oops, I think my wife is/was calling me. .. dovis 10,000hz variable I hear 25000 hz =) razorlight i hear the 21.000 and downwards. :) that's good to me ;)) Terri I could hear all levels quite well and I'm 57. John I'm 34/m. I can just slightly but clearly hear the 17k, and very clearly hear the annoying sound at 16k. But when I play the 18 and 19K, I can't actually hear the tinny noise, but my ears feel an interesting sensation of being congested when I listen to those two. John Crap, the ringing continues for a while... Zemaits I am 24 and I hear 23 K :) Joe I had only heard about this recently when i saw on the news a shop owner who had a problem with teenagers hanging around outside of his shop. Lots of my friends have the sound on there phone but I seem to be the only person that cannot hear it. I dont know if I should be worried but I am only 18 and I dont think I can hear any of the samples above. Can any body help me out? Rafael I can hear up to 20,000 hz, no problem. After that its just plain nothing. XM I'm 36. I can hear them all with the exception of 24,000Hz. Seems strange that I can hear 25,000Hz but not 24,000Hz. alvin i'm 23.. i can only hear until 15khz Quicktime player. but i can hear until 20khz by using Windows media player. strange.. Audrius 31, all range! Larry I'm over 40, but have always been musically inclined, and many times bothered by loud and distorted music that others don't seem to hear. I got up to 19,000. That explains a lot of times where I will ask people,"don't you hear that?", and they look at me like I'm nuts. Agne hi di ho :) I'm 16 and I can hear 23,000 :O it's not a joke. Skippy Don't forget to factor in the frequency response of your electronic equipment. For example, I can hear the 13khz tone with a good set of headphones, but I can't hear it with a crappy set of computer speakers. Ashley I am 19, so I guess that makes me still a teenager, but I could hear all of them nice and clear. matt i can hear the 25,000hz nd all the others u need porn on here just jokes lol great site man do i hear about 20-21. I'm 18 Judith 54 yo female: I can hear your files (all annoying high pitched whistles, except for the mosquito sound which sounded like traffic, a highpitch laugh/giggle and a metallic clinking) up to 22k Hz with our computer speaker volume turned down fairly low - my husband would have trouble hearing normal audio. I also hear a high pitched whistle on our church speakers (like the beginnings of feedback) and no-one adjusts microphone levels to eliminate it (except me). Not only that, our computer emits a constant whine. Still, perhaps there could be something wrong with your files. Dave I'm 28 and can hear the 20k. Beyond that there's a noise, but it sounds lower pitched than the 20k. Not sure why. Dave I'm 28 and can hear the 20k. Beyond that there's a noise, but it sounds lower pitched than the 20k. Not sure why. i'm 17 and i can only hear up to 18,000 Joe The thing I'd like to know is, how much are we actually missing? I know we were all able to hear higher frequencies when we were younger, but perceptually how different is our hearing these days? If our ears were suddenly replaced by ones 10 or 20 years younger, how much more crisp would things sound to us? I am 32. The proper "hearing" result for me is 16kHz. I am "aware" of the 17kHz tone almost like you know when there's a traditional 50Hz TV set on in the room (although I guess the older I get, the less I will be aware of such things). Would be really interesting to plot a graph and see what the average is. Jasmine Hey Im 14 and i can only hear up to 21kHz. Do i have problems????? P.S. This is a really long comment list. AJ I'm 18 and I can barely catch 18,000. Its the same kHZ as the sound of silence (you know that ringing in your ears?) Garrett 20 i always listen to loud music but i had something strange with it. i could hear all of them except 21khz. 22khz was loud. 23k-25khz was very very soft. Tomas Hi, i am 23. I dont know why, but i could hear all the samples :) all, including 25khz :) my speakers were set not too loud. James hey i can hear up to 25k fine i would be intrested to try higher khz oh well ty KLickX Im 17 and can easily hear them all up to about 23000. After 23, I have to close my eyes and concentrate hard but can just hear the squeal at 25. Funny how it sounds lower pitched at 25000 though... Ruwan I am 36 male from Country Sri Lanka.I can hear two sample sounds and 19000Hz.Can't hear 20000Hz and over. Kaze Lol, im 18 and i couldnt hear sh*t on any of them hz (only one i heard was sample 1) maybe because of my speakers and noisy PC.. ill try it with headphones in a min Soul Music I'm 23, using an above average quality headphone by Sony and was able to hear up to 21,000 Hz with the volume on max. I think I could had easily heard another 1,000 Hz or so if I used my high quality studio monitors or headphones. Dan I can hear up to 20 perfectly and then nothing. my question is, why do both ears get damaged equally? Is it not possible to hear out of one ear at a higher frequency? Wesley G May i just point out that if your speakers cant handle these high frequencies, they will appear lower than they really are . . . I have a pair of Studio monitor headphones by song that go from the 20 Hz - 22,000 Hz and when i listen to 20,000 i can hear there is something there high pitched but its not terribly loud but alightly anoying. I am 22 (UK) i hear 19,000 very very well. These i did with Adobe audition my own frequency tests BullGates Well, on the same computer on Windows I could not hear 17.000 Hz, on Linux I could hear them all. I guess Windows is a real old operating system! lol Myka I'm 19 and 19,000 was the highest I could hear clearly. This is craziness...but I've heard about the cell phones w/ ringers that only kids can hear...and I believe it with this... Virgil I found this a while back, my hearing cut out at 22,000 (I was 15) since then I've been to many concerts, including an AC/DC and Styx Tribute. My hearing has gone up to 25,000. Weird huh? Jamie I am 26 and i can hear them all, and i have a big A$$ stereo system in my car that i have turned up loud all of the time. SWEET. Tim I am 15½ and I can hear all (up to 25 kiloHertz), but at 25 i must turn up the volume a little bit. Morris Listen, and be surprised. I have gone to my doctor, and there's nothing wrong with my hearing. I can hear sounds up to 65 000+ Hz. I was born with this. I have nearly as good hearing as a cat and a dog combined! ;-> Morris² Sorry, my age is 56 YES 56. Chris I'm a 19 year old male and I could hear 19k but not 20. Chris i am 15 and i can hear up to 18 and then 20 but not 19 for some0 reason Tiara IM a 17YRS old and its ODD that I can only hear up 19000. umm.. im gone have to check on that!! Diana The 21hz and up arent working :( Carl Im a little confused here, why does the 22 000 sound lower than 15 000? Ichecked if it really were 22000 hz by nero wawe edior, and it was 22 only and no background noise. What is this phenomenon? Speakers? Ears? Or it is the way it should be? Please answer. john j im 46 can only hear 10,000 wow Hayden i can hear all the way up to 25000...i bet i could get 26000 Tamara 32, Can hear out to 18000 Hz. I think that stores may lose business using a mosquito device. I, for example don't shop for clothing in stores where the computer monitors emit painful high frequency whines. Berto i m 20 and can hear them all,but with problem for 24k! great site ^^ Peter I'm 34. Weird results... I can hear up to 15kHz with normal volume level. If I turn the volume up quite a bit I can hear 16kHz , and 17kHz is actually quite pleasant pulsating one? But when I turn the volume down to the normal level I can still hear 20khZ a lot better than all those in between. Weird... Peter again Hmm I've used my Technics RP-F-400 headphones with normal volume level. According to the spec they can output frequencies up to 27Khz. I can hear 19 and 20 kHZ MUCH better than 18kHz. BTW excelent Idea with that test Ochen :) Nicram Strange. I can hear al from 10KHz up to 17KHz very well. Then i don't hear 18KHz at all & 19KHz very little. From the 20KHz to 25KHz i hear them very well. Using normal volume set (both with speakers on the wall than are good & with ear one)... Kees Ye i can hear all the tones, up to 25k, but the 25k is louder and more annyoing than the 21k.. Hmm, my old speakers cudnt even get above 20k -_- Emiel i'm 17 and i can hear them all. Kristin I work in a high school, and I have to say...kids would not get away with this ring tone. At age 25 I heard it clearly at 15,000 and then after that, I felt pressure on my ears though could not really hear the sound. My brother is thirty and could here as high as 14,000 and our coworker (who turns 40 next week) only heard as high as 13,000...and she strained to do that. I read that 14500 is what a lot of the ring tones were... since lots of teachers are between 20-30...i'd say there are a lot of kids getting in trouble for cell phones. T-Dog Close to 39 years old and can hear up to 20,000. However, I had a hearing test at 23 and was told I tested higher than anyone the tech had ever tested. Since then I have played in a rock band. Wear your ear protection people! john i am 17 going on 18 and i can hear to 22k i dunno can i hear more cause my computer wont play then Professor The wav recordings from that site cannot be used as a testing point, i can hear 25KHz and that is BS. Okay, wanna hear explanation, Nyquist data rate, for restoration of modulated analogue signal is stated to be at least twice the original signal frequency, thus by playing 25KHz tone at a supposedly 44.1KHz (check the WAV file, its 44.1KHz sampled) aliasing will happen and at aliasing, its all yada yada yada.. But still, testing the 20Khz tone, i can still hear thosde dem sound (I haf affixed tat my listening limitation is at 17Khz) so wat gives? Well, i listened to all samples above 15Khz..they fcuking sounds the same! Well well well. placebo placebo without science, thus i conclude, humans do not haf the hearing of a dog. If anyone can listen to more than 22KHz of sound, they wouldnt be sleeping well with all those noise at that white noise range. Btw, if u guys really wanna test ur listening range, do as the others said, listen to 1KHz at a normal level then shift the frequency but not the volume. AND do no freaking use the recorded sound from that sire, get urself a tone generator, dohhh! (P/S: Tone generators efficiency is highly dependant on ur computer's sound cards ability, u might get a different result). Michelle I'm 20, and could hear up to 16,000 however i also have a hearing problem especially with high pitches..if that helps at all Pilot I'm 33 and the highest I can hear is 13,000 Hz. Lesson learned (too late) - don't fly noisy airplanes without hearing protection! French I'm 22 and can hear 1900 Hz with no problems. Shane Fowler I could hear the 14k clearly. nyiddle I'm 15 years old and can hear all of them easily. 19k is the most annoying for me. My cat freaks out at 23k. It's kinda funny. Hard Rocker HI I'm 21 male and I can hear up to 17khz loud and clear! At 18Khz it gets tricky , I can only perceive a faint tone.... but the odd thing is that , I can start hearing again at 23Khz , because of the low sampling-rate signal distortion! Teh_0wner Um... I guess I should be able to hear all of them since I am only 18. Very nifty site, thanks. :) Shan I am 31 yr old male and can hear up to 17khz.. Colin I can haer all of them, and I'm 16. The last one is harder to hear though, Mt ears wont be the same after this. Booker My cat, dog, and two kids do NOT thank you for this site! LOL! I'm 36 and can only hear up to 13. My cat's hair all stood on end, my dog that never barks, did, and my kids took to hiding in their room chanting, "I'm not listening! I'm not listening!" Hmm, this may come in handy. . . David I'm 17 I could hear all of them 10k-25k but for some reason I could barely hear 10 and 25 was the clearest i dunno if thats how its supposed to work or not Chad im 16 and i can hear all of them clearly, even 25,000 toad feeding mosquitos peanut butter & jelly will only make them very mad Percy 51 years old. I can hear 13kHz clearly and 14kHz if I turn my head to the side???? on my laptop and 21kHz just on my desktop. Does this make sense? colin How could you barely hear 10, its the loudest and 'sorest' of them all, really goes through me. D.J Nate I'm 20 and could hear all of them. DibS Any of you who said you can hear over 19,000Khz are full of crap. Unless you are using laboratory quality equipment, your speakers can't even reproduce those frequencies so shut up. This also applies to the author's frequency analysis of the sound file. Just because data exists at those frequencies, doesn't mean that your speakers can actually PLAY THEM BACK. So your graph proves nothing. That being said, fun post. I'm listening on a pair of ADAM S2-A's and I could hear 19,000 fine. Above that, who knows. These speakers supposedly reproduce up to 35Khz, but who knows how well. DibS Also, age is not the only factor in your hearing's frequency range. Every time you get an ear infection, that top number is shaved down. Also any time you go to a loud concert and you get that muffly feeling in your ears the next day, you are sliding farther and farther from 20Khz. Just something to think about... me STFU speakers can play them, im using headphones idiot, and i can hear them no bother, 25000Hz sounds very low to me but it still plays fooool. Kristan I'm 19 and I can hear up to 20,000 just fine. But seriously, I can't hear 21,000, and it's ticking me off! Mike I can hear up to 25khz.. no modifications, maby its the fact that i have hales in my eardrums. Mike Holes** kost shit im 14 i can hear 21 a little but 19 the best al thought its ****ing anoyying Paige I'm 15 and I can hear 21,000 just faintly. But it might be my old speakers. Funny, my parents could only hear it up to 15,000 and my teacher(who originally introduced it to my class) could only hear to 16,000. Hmmm...I wonder if I did this before I got my iPod if I could go higher. That would be interesting. ben i am 14 and can hear up to 21 Jen I'm 15 years old, and I can hear up to 21000Hz. I've always known I have a good range, I can hear a TV on even when it's muted. TVs emit very faint buzzing/ringing noises very close to what I hear at 21000Hz. Kristin I'm 18 and I could only hear up to 19 reliably, but then I play piccolo and have since I was 12. An interesting fact is that one of my flute professor's teachers had played piccolo professionally for many many years, and could no longer hear the entire upper range of piccolo... Stephen I'm 15 and I hear all of them perfectly, except 22. Why is that? :/ order phentermine Cool site. Thanks:-) Stephen I'm 15 and I hear all of them perfectly, except 22. Why is that? :/ Roger okay here is the problem, this test is somehwat innacurate, my headphones a gmaing headphones made by Senheiser is the model Hd555 with a range of 28,000HZ maximum. and after maxing out the volume i cud hear the 25,000Hz no problem. so its innacurate. roger altho on a MIDDLE volume settings we could test perfectly, i heard 21,000 and my sisters boyfriend heard 18,000 quite interasting Mike I'm 37 and can hear 16,000hz but can't hear my kids mobiles ringing (god it sucks getting old) Jeff I'm 44 and can only hear up to 15000Hz, but 16000-19000 make my sinuses hurt. bethany this is awesome!!! I heard to about 17000hz, my sis-18000hz,mother and dad about 15000hz! bethany oh yea 20-13-37-40yrs Mel I am 24 and i could JUST FAINTLY hear 20,000HZ, but my partner whos 23 could hear upto 22,000hz! This is soo weird!!! Nelson Alright - whose the wise guy that sent me blank files! Not really - I am 60 and KNOW I can't hear above about 8,000 PS - would be a kindness to add files at the low end (5-10K) Aj I am 22 almost 23, I could hear to about 20,000, I could kinda make out a couple above, but not to the point where I would notice it if i weren't listening for it. Paul I'm 27 and surprisingly I could hear all the way up to 24,000Hz, despite listening to music all the time. I thought I wouldn't be able to detect anything past 16 or 17KHz. The samples from 20,000-24,000 made me feel somewhat light-headed though. Also a note for anyone else listening to these samples - if you're listening through PC speakers that has bass/treble controls, make sure you have the dials set to +0db otherwise it amplifies the frequencies' harmonics somewhat. Angel Im 17 and i heard all of them... up to 25... can you put more??... about up to 30?... i think? Keiji22 I'm 19, I heard every single one of them perfectly. Perhaps you could post more? Some even lower than 20Hz? How about turning it all the way up to 60KHz? ScottyDoo im 20 and i like drinking rum! 17,000Hz of rum!! kayla im 23 and i heard up to 20hz but not 21 odd i'll have to try it on my mom Daniel I'm 17 and I can hear up to 23hz. Classical music David I'm david and i'm 19 I could hear all of those except 22hz but if i up the volume, i can hear something... it's normal? i always listen and play heavy metal with high volume rate lol! William The last one that I could hear through my speakers was 17,000Hz. Age: 34 Worked for years in noisy factory environments. I was helping one of my professors with some mist netting of bats a couple of years ago (started University later in life), and he was telling me how sometimes when he does demonstrations of this procedure for children, that they find it painful on their hearing to be in the area where the bats are caught in the net. That was the first time that I had heard about this subject of which this web page pertains to. Pat Age: 17 I can hear it distinctly until about 23,000, then it gives me that headache feeling everyone else describes until 25,000. It is weird though, because I can't hear anything above 19,000 when I generated my own by Audacity. Terry 37 and can hear 20,000hz Jahn and Kat We are a couple 37 and 39. we both hear every single one of them except clearly except for 24. Maybe our logitech speakers? Not that we can't hear it: I mix music and it kinda sounds like a tv is on: I have always been able to hear that high pitched sound from far away: like it sounds liquidy and shiny, slightly brassy and piercing. Not loud, but if electronics are on, it is like I feel it with my ears. yarr 25kHz+ :/ in other words, I'm a dog(atleast others now have another argument towards that end). Darcy These sounds are not considered a valid test of hearing by a sound professional at hyperacusis.net David and Andrew Kindred I am 39 and can hear up 18K, my 11 year old son can hear up to 19K. We don't know how much of this is a factor of having cheapie speakers attached to the PC. jose loya i am ten years old and i could hear up to 9,000hz garmon i could only just hear 17000 and im 14 i always blast rock music and metel etc so i guess that explains why i cant hear more that 17000 billy after a reely loaud rock concert i always hear around 15000 i cant hear 1600+ kay & mo you hurt my ears. my friend and i heard it, and we are 12! Doc Tomorrow Something's not quite right with those samples: I can hear all of them clearly, save the 24kHz one, but when I tested it out with a signal generator, I found I can't hear anything above 16.9kHz. Try downloading Frequency Generator 2.6 or some similar software and see it for yourself. Jonathan im 16, i hear all except 21,000 22,000 23,000 24,000 and 25,000 hurts Gareth I couldn't hear 17 18 or 19 KHz, but could hear 16 and 20 just fine. What's that all about??? Graham Hi all, Im 34 and a Sound Engineer. I can bearly hear 18kHz which is very good concidering my job and all the concerts I've been to. To all those who claim to hear above 22kHz. Im sorry but the human ear can not hear above that. You might be hearing harmonics from the sound affecting the lower frequencies. To anyone above 22 yoa claiming to hear above 20kHz, again Im very sorry, I dont believe you since hearing naturally starts to degrade around 2o yoa. Again you could be hearing harmonics from the sound affecting the lower frequencies. And this is interesting. A device called a mosquito was developed to chase away teenagers hanging around shopping malls using high frequencies. The sound made their ears unconfortable but it didnt effect adults (i.e. the ones who are there to buy stuff) couldnt hear it. i hear all of them no problem at all naynay hey I could hear them all!!! Im 14, im ALWAYS congested, I can hear as well as my mom in volume and I can hear to 19, but I feel sosmething in my ears, just this faintest of whispers in my ears, on 20. I may be able to hear higer freqencies if I had taken a decongestant, I may have a chronic ear problem which causes me not to be able to hear as well, but on a perfect day (which happens once in a blue moon, also when im on 20 diffrent kinds of decongestant) I can hear everything, or so I remember. But heck it seems to work as a pretty good earplug, hey, everything bad has a good side, eh? Name Anyone can hear all of them in huzzles. Try to listen out for high pitch spuekes that hurt your ear. Weird thing is, I can hear 25,000 this way but not 20,000 to 24,000 Name Nope, sorry I can hear 21,000 to 25,000 (just had to turn it up.) But I still cant hear that 20,000 hz. tovli 54 years old, learning to play flute. Left ear heard 10k, (just measured yesterday 10k weak, 9k strong). Right cannot hear 10k, (9k weak and 7k strong). Low end seems to be 23 hz. Vivien I am a 63 year old female and can hear to 13,000. My husband is the same age and can hear up to 12,000. dad io li sento tutti ho 26 anni... ;) Tamir I'm 14 years old and i can hear up to 24,000. my brother (18 years old) can haer up to 25,000 EAH_XxHeReTiKxX 16 years old - I can hear all the way through. This to me is like the ambient noise of televisions - my parents never notice it but it is very clear to me. MCRacing 32yr male. I have worked in factories, listened to loud music, raced motorcycles and I could hear them all. 22,000 was harder to hear for some reason. Ben G. I just turned 13 and i can hear up to the 19000 mark.... my 43 year-old mom can only hear up to the 13000 Brendan I'm 23, i'm a full time construction worker subjected to copious amounts of noise i also have a large car audio system capable of 118db i regularly undergo hearing test for my work, i knew i still had excellent hearing but was surprised that i could still hear in the 21000Hz range! Cool site Thanks!! Aaron Uhm, I could hear them all, and I'm 17 y.o. male. :p Rhiannon I am 19 and could hear up to 16000 - tried my kids and they are 6 & 4 and they could only hear up to 19000. Rhiannon Sorry, I am 29 (not 19!)and can hear 16000 Martin 16, i can hear 25000 Max i am a 15 year old girl and i can hear them all very well, up to 25000 max just to point out... the higher sounds sound a lot like the noise the television makes whenever it's open... me and my 20 year old sister get annoyed by it, but my parents can't hear it. Beth I'm a 63 years young female. I could just barely hear 12,000, and heard nothing at 13,000. Very cool site! :) cheap phentermine Nice site. Thank you. Matt Campasano this is a pretty cool site. my intro to audio teacher introduced my class to it in a rather unusaul way. he can not hear anything above 12khz so this test didn't bother him one bit. the test i speak of is this. one day with out us noticing he left this website open and would click on one of the links above 12khz at random untill someone stopped class to make a comment about the very annoying high pitched sounds coming from the room. I'm 25. I'm getting fat, I'm getting bald and I can only hear up to 15 000. Holy shit I'm getting old. T_T Scott Johnson I have always thought that I had good hearing, but it seems that I can't hear anything about 14kHz. Gosh! Wayne 25 years ago I developed a constant super high pitch that has increased every year, to a point that is equal to scratching a chalk board, or standing next to a jet engine when it's after burners kick in. I am 52 now and have had many different doctors give me the same answer,not a clue. can any one help me. AJ I'm 35 and can hear 21,000 and 24, 000. Mind you I get annoyed when I am sitting in rooms and can hear people's watches ticking. hannah i'm 16 and i can hear up to the 22,000. i can hear the start and stop of the rest of them and it makes my head feel funny. i can walk in a room and know if electronics are running (tv is on, radio, etc.) robert Age:53, could hear 16,000 clearly, after that I think it was imaginary hearing, but had a "feeling"- I expected a lower limit as I've spent ages using loud headphones, and playing in a band, so I am quite pleased. Thanks. Random I'm 14 and I could hear all of them, and they were freaken LOUD!!! My ears are still ringing from them now. Bruce A 37 y.o., 30 y.o. and 11 y.o. here. We heard them all. Some I (37) could only hear out of left ear and not right. Mark and Katy we can hear 20000 hz easily. Eric 26/m and could hear all ranges. The 25 though I barely heard. Used high quality headphones. Eric I'm a 63 years young female. I could just barely hear 12,000, and heard nothing at 13,000. Very cool site! :) Frank Sorry, I am 29 (not 19!)and can hear 16000 Lola Im 20 and i can barely hear the 17000 But I kill ears with loud music all the time so maybe thats why... thanks ochenk that was cool Nancy I'm older than dirt but I can still clearly hear the 10,000 Hz sound. Mark I just turned 35 and can hear all of them except for 22,000 hz. Poom I can't "hear" anything above 16000, but the files make me physically uncomfortable until about 21000. I'm 27. David I'm 15 and I can hear up to 19,000. Maybe because I've been drumming for about five years now and listening to loud music. So yeah... I guess 19k isn't so bad. You know, some kids have used the higher pitched for ring tones to use during school because teachers can't hear it so they can use cellphones without getting caught. lol. Lucas I can hear everyone of them wicked well, except for the 20,000 which gives me some difficulty, im 15 :D Chris im 12 and i heard up to 20000 but after that it didnt have any affect Lars Well, I could easily hear both sample files, the first sounded like CRT TV noise (higher in frequency & low volume though). The second I suppose one need to be totally death NOT to hear?! By the way, I'm 40 years old. Lubo I am 31 and could hear up to 19 kHz. Information for those, who are depressed by their limited hearing range: people, first find out what is the range of your hardware!!! If the speakers or headphones do not play it, you will never hear it. Balkan-boy Age 13 i can hear all of them but the last 2 not cleary. and my father age 49 can't hear the 17000hz sound. thx for this site. it's niiiice. CrystalRange2950 Without turning up the volume more than 1/8, I could hear 16,000 Hz, and I'm 17. When I blasted my speakers and volume, I could hear all the way to 25,000 Hz. Although it was very minor, I could definately hear it. Kungfukitten Hi, I'm late to the game but I thought I'd put in my 2 cents. Female, 38, been to a lot of punk shows in my day. I could hear 14 perfectly. Above that I couldn't hear the noise but I got a stabbing pain right between my eyes on my forehead - in my middle eye. Isn't that strange? I need to try it at work where I have headphones and have someone push the play button while my eyes are closed to rule out any psychological effect. This was fun thanks for taking the time to put up the tones. Laura I'm 20 years old and I could hear ok up to 1600 until unfortunately my speakers gave up at that point!! I'd like to hear these tones again on a better computer to test how far my hearing goes. Johno Hi! I'm 27 and not problem with 21 000Hz. Thx for good web site. edgar omg this is crazy! Z I can hear 25000 clearly Darron I'm 41 and can hear all of them. Do I win a prize? Jacob i am 18, i can barely hear the 15K one, and now i have a ringing in my ear that wont go away joe 20 and can hear all no problem at all James I'm 21 and can hear them all, 23K is very easily audible, 24K is significantly less but can still hear it. 25K is only just noticeable Tony I'm 17 and I can hear up to 17000 :( carl i'm 20 and i could hear up 18k but it caused a swirling in my ears, my head hurts. bradl3y OMFG im 17 and i could only hear up to 15 WTF MAN probably because i go to sleep listening to full blast music hehe Mike 19K really hurt, but I couldn't hear 20K I'm 23 and frequently have my ears ringing for days after certain clubs and events. Bill 21 years old and i can hear up to 17... and it makes me want to eat myself. Tom No problem, all the way to 25k. 40 years old, I've always avoided loud sound as much as possible. When I was a kid taking a tour of a wholesale company, I asked, "what is that high pitched sound? It's very annoying." No one else in my class heard it. It was to eliminate mice. I can no longer hear most of those ultrasonic pest control things, but still have exceptional hearing. Roxy 19 and I heard them all! nico 21 and i can hear all of em...friend whos next next to me is 18 and can too I'm 31 and I can hear all of them no problem.

Andrew and Mallory reposting, We're both 18 and can both hear up to 23,000 with the speakers at a normal volume, but can hear up too 25,000 with the speakers sound increased. i can hear all but 25000 im 20 scott Never mind i can hear all of them i just had to put my ear to the speaker and when i did i could hear it clearly you should add more above 25000 i would like to see how high i could go...20 Pete im 17 i can hear all of them ^_^ Borjan Hehe i am 14 and i can hear to 22,000Hz and after i listen nothing :D! Mental 23.... heard till 16.000. Lot's of party. Lot's of disc-man music. Errr.... My ears are older than me? Psy-trance rulz! Borko Hi, I'm 26 and i can hear 18.000, but i'd like to underline that a good equipment that can reproduce the sound with so high frequency is also very important because not all speaker or headphones combined with amplifiers can reproduce the sound on frequency above 20000. Thanks Borko Hi, I'm 26 and i can hear 18.000, but i'd like to underline that a good equipment that can reproduce the sound with so high frequency is also very important because not all speaker or headphones combined with amplifiers can reproduce the sound on frequency above 20000. Thanks Eio Hoi 32 and heard the 17 000 - but dosen't the speaker type (cloth, paper etc.) effect this? as well as volume? ferinstance' - 16,000 sounds much fainter than 10,000 - is that the hearing loss or volume played? BTW, What Hz does a regular moniter / TV come in at? I can always tell when a TV is on, even w/ the sound turned off. hi I can hear 18000 i dont get it. what are you saying? Kevin I am 17 and can hear 18000 perfectly. i start to lose it at19000 but its still audible. i cant hear 20000 Colin It's important to note that there is harmonic distortion in a lot of these; if you think you can hear them alright at 25KHz, then I'd love to see a medical report that confirms it. There are a lot of things that make this not valid past a certain point (encoding bitrate, harmonic distortions, the fact that most people have computer speakers worth about $6, etc). If you truly want to get a feel for your hearing, get a good sine wave generating program, a pair of good speakers or headphones, and you'll notice a huge difference. zew im 22 i can only hear the 10khz file. I guess the years of clubbing have done their thing ErniE Im 17 years old i can hear all of them :D Zeng I'm 31 and can hear up to 24 Victor I'm 21 years old and I can hear this good only at 17000, up to this no Brandon Im brandon and im 22. my wife kathy is 20. she could hear to 15 and i could hear to 19. after 19 i couldent hear it, but it kinda hurt when it played. funny thing is that i listen to death metal and grindcore and shes into country.guess that disproves some peoples ideas about loud destructive music. Dennis I'm 29 and can hear all 10~25k and this is at around 25% volume or half of where I normally keep it for music and movies. 24k was probably the most irritating. Chance I'm 17 and managed to hear up to 21,000, couldn't hear 22-23,000, and then 24 and 25 were loud. jordne i can hear upto 20000 and i am 18 pretty freaking annoying Darko im 28 i can hear all of them micke im soon to be 25 and I can hear up tp 21 Kurt I've just turned 46 and can hear all of them at normal volumes.

My wife can here 19khm and she is 22. Dessa Lol, I can hear them, Like up to 21,000 and then I can't hear 22,000 but I get a headache, and then I can hear 25,000, so it's kinda weird. I got my mom to listen to them, and she can't hear 15,000. She can hear 10,000, and I was going to ask her to listen to the rest, but she got a headache. Heehee. BTW, I'm 14!!!! Although I haven't listened to 23,000 and 24,000... I'm going to. drew 17 and I can hear 24,000 Gorilla Im a 20 year old male ive abused my hearing with car audio for at least 4 years now i can hear all the way up until 24KHz im sure my low end of hearing 200KHz and below is shot, though. Cherie I'm 32 and have worked in a nightclub for eleven years. I could hear sample file 2, and everything but 14K. Dmitri I got 23k.. perfect hearing.. (im 19) mike why are people still commenting. nobody will read your comment. this page is miles long. if you were going to post DONT. Derrick I'm 31 and i could hear all of them but 25000 michael I could hear the 18kHz but nothing beyond that... I used to listen to music real loudly and I've been to many concerts and car races which probably didn't help... aaron i'm 26 and can hear it at 19000 although my dog can hear everyone of them it was interesting wathing her look at the speakers at 25000 Will woohoo, i'm 22 heard everything up to and including 25 khz, though it gets a bit quiet. no wonder my friends think im wierd for telling them to turn their damn car's system down... Tobias 42 jahre, männlich, höre 19k :-) 42yrs, male, hear up to 19k. When I was in the army, they performed a test on us on how good our hearing was. I couldn't hear shit from those headphones. Doctor yelled ar me: "DO YOU SPEND A LOT OF TIME IN DISCOTHEQUES??" Me: "Nope" Turned out the dumbfuck didn't plug in the headphone correctly... igor I'm from Macedonia,end I hear up to 20.000Hz, end I'm 20 yeas. Alex I'm 20. 17,000Hz. Wes i could hear every single one of them at the same volume, and i've had tinnitus for a few years now, but i am only 18 and studying sound engineering... but i think i hear too much, ive never seen a TV that didnt make a ringing sound, no its not my tinnitus... Carl the only 2 that are difficult for me to hear are 24 and 25. They are like a very subtle ringing in my ears.. BUT i can definitely hear them a little bit. Carl By the way, I forgot to mention, I'm 20. Josh I'm 23, and can hear up to 21. Seems like I can "detect" a sound above that, but can't actually hear it like the others. Marjan I can hear to 16.000 and i am 19. I play clarinet for 10 years. Could that made me listen only this much? I am not worried at all, i am only qurious. charlie just turned 20 and i can hear up to 22 just fine. after that i can only tell when the file starts and ends. i think my speakers emit a very high frequency and maybe i keep thinking that those sounds are my speakers. Chris Well im 14 i can hear to 19 very well, but 20 nothing. who knows if thats normal Soopa i can hear it to 22 is this ok i have 20 years Stefan what about us-DJs. im 18 and i can hear to 20k. shouldn't we have lower range? damn my ears will blow :D Borce 27 years old, I can hear 24k.

The 25k was more noticable then the 23k. I am 20 I HERD ALL OF THEM EXCEPT FOR THE 24k johnd I am 46yrs old. I can hear only 10k and 11K. Matt I had head phones up but i herd them all. IM SUPER HUMAN!!! (20) mykal i can hear to 19k then i can hear 21 and 23. thats it Jeremy It should be noted that most soundcards run at a sample rate of 44.1khz, this means that your soundcard will only be able to reproduce frequencies up to 22khz. Im 23 and can hear up too 23khz. I have very sensitive ears and try to take care of them, as I am a musician matt i can hear them all.. i am wearing headphones with the volume maxed.... would this affect the results? Night Anything under 20000 is pure death to me. They managed to make this shit useful? soleft I can hear all of them clearly. I'm wearing headphones. Tishea 31 years old here. I could hear all the way up to 19,000 through plain laptop speakers. Might be able to hear more if I was wearing headphones. Had no problems hearing both Sample 1 and Sample 2, though. Davor I'm 20, I'm from Macedonia and i think i could hear up to 25.0000 even though my speakers are not so good... Greetings scaffy i am 31 yrs old and i can hear ALL the samples. i work in construction aswell so i thought my ears would be bad with all the noise i work around. :) Nick I'm 22, could just about hear 18.

Faca Propusnica I have 18yr and i heard up to 17000 Sparrow Hey, Just for your records I'm 22 (just) and could hear up to 21,000Hz. We did a similar test at school ages 15 and I could hear higher than now- although I think 21,000Hz is still abover average for 22. Excellent site!!! dzuljo I'm 32. 16,000Hz. Bryan I'm 18 and i could barely hear 20,0000 Brandon I'm 18 years old and I could hear up to 21 tomi Hi there, just wanted to say that you should probably run another check on those highest frequency sounds (above 22000) because I can hear them all and my friend too. We are 23. The reason is that my father (48) can't hear 15000 but CAN hear 20000. Thanks Mike 21 and could only hear up to 20K, although that's about the range that my Marantz speakers top out at so I don't know if I can go higher or not. Maxim I can hear 22.000 but its so low !!! Lichi I'm 21, and after a decade of going to metal shows, I thought my ears were shot. I could hear up to 24K Hz. ^_^ Crank Hmm...im 18 and can her up to 25.000....but its not a good noise;) Chris I'm 22 and I can hear the 24k fairly clearly, but i can't tell if i'm imagining the 25 or not Darko Well, this is very interesting , I'm 22 and I hear up to 19000, and now I'm feeling bad and maybe I'll throw :) But for higer frequency than 20000 I beleive that we need special sound card and special speakers! I think that comercial speakers goes up to 20 KHz , but I'm not sour! :D Bobi I clear all of them till 22000 im a 21 years old male Seljak NA MAJKA VI PICKATA , MI SE POVRAKJA SEA!!! :)) 19 yr old male. could hear 22,000 Cody 15yr. old male, could hear up to 23khz with no problem but 24&25khz were just buzzing in my speakers. Avid in loud music and the bass portion of car audio. 1100w setup at home and adding more every day. Vince 18 year old male. could hear 25000... post higher samples Tomy Nas I am 27 years old and i could hear 23000 with headphones. 24&25 could hear only a pitch in the beggining...maybe my ears or my headphones or my soundcard... Bazza ! I'm deaf and i could'nt hear a bloody thing ! But...i'm sure i could FEEL the noise coming from my speakers...! HOW WIERED....! I must be a freak ! Lol, Lol, Lol, SHHH ! Sam Well, pretty weird indeed, I am 14 (almost 15) years old, and sadly i can hear only up to 17,000 Hz, Later on I can hear 18,000 Hz but very weak and thats if i put my mobile phone next to my ear. My friends (which are at my age) can't hear anything above 17 (there are some who told me they hear 20,000). Amazing thing. Is it possible that later on (at life) i will be able to hear the others ? Kevin I'm 22 years old, and can clearly hear all of the ranges. Is this strange? tim im 15 and can hear the 24,000HZ Lu Teck Wei Is there really sound in the highest HZ? antx All this sounds seems to work for me but 18.000HZ and 24.000HZ. I'm 20 and I used to kill my ears with high music every day. THIS IS SERIOUS: DON'T HEAR LOUDLY MUSIC EVERY MONENT, SPECIALLY IN WALKMANS/IPODS & OTHERS. Very good site. Thank you:-) Very good site.

Arie I'm 21 1/2 and I can hear just up to 20,000 -- to the point where it's this uncomfortable sound.. where it seems that not only can I hear that frequency, but feel it too. Excellent study, though -- this is so interesting :) Nico I´m 20 and i can hear just up to 21.000 Hz. kiddo I can't use the 21hz and above because my comp won't let me... could hear 20 just fine(with speakers cranked) but I can't know about the 21 and above Migue I'm 19 and I can hear all the sounds jestre 26yo~ i can't hear anything above 18k. :( but i get some irritation from 19k ~ 22k. yup, too much music is bad for us. side note: technically, natural human being response frequency is from 22 hz ~ 22khz. there are some people that has a wider range though, but it's really rare. if you can hear those 23k and above, protect ya ears. LSD recently i heard a new ringtone called "dont play this"...it was 18000 mhz sound.I found it on the net.U can imagine the fun i'm having watching the peoples faces when my cell starts to ring.The best part is that they can't determine the source of the noise. :) mastermind Il molling regna sovrano anche qui. I Rock You Suck. End of story. dbettcolo I'm a 55yr old musician and can hear 20MHz easily. 21MHz and above are totally gone - not even mild irritation. Wild! AlejandroAR Im 14 and mine is 22 ^^ Very good site. Thank you!!! Kyo My mother hears 20khz, and she's 52. Mrs Sam I'm a senior year physics teacher at Rushmore High. Hz is the number of waves that pass a point per second and it is widely known that humans are only capable of hearing 20-20000 hertz maximum. I do believe that computer speaker systems may be altering the frequency of the sound and ego may also be a uncontrolled variable in this experiment, which would result in unnaturally high results some people may be claiming. I would advise you all not to add the results of this test on your college application. griff age 12 i can hear all of them and i now wish i hadnt tried all of them coz it hurts like hell, i see why they use it to stop teenagers from loitering or watever it is. how can i get it onto my mp3? ur mom! only nerds come and take this test cmc 26y/o felmale-- can hear 16 but not anything above that. that's right in my supposed range. but, it does sound like the test really isn't trustworthy in a broad sense. would be interesting to read about a controlled study on the topic. Jill I could not hear any of them at all, even with computer on full volume and hearing aids on full vol, using a T-Loop!I've only got a moderate hearing loss which I've had since a child, but all this is way beyond my threshold. Could hear the crackle of the tcoil in the aids click in where the sound must be, but heard no sound. I'm only 40! Daron uhm, maybe I have great headphones... but I can distinctly hear 25kHZ Daron Actually, I can hear 10hZ-25kHZ ... but have yet to try to hear anything lower or higher at the moment... need more sounds bits :D Max What gives? I'm almost 50, always on a farm with lots of noise and wind and I can hear all the sounds at a normal volume on a Windows 98 old farm computer. One thing I didn't do was sit in clubs with music or wear headphones. Mike hey im 22 and i could hear up to 21,000 Hz Johnboy I can hear op to 25.000 no problem. Are you sure the sounds are at the correct hz? 19 year old Chris I can hear 25,000 if you put the volume high. I'd say thats the main factor. MIMI IM 13 I CAN HEAR THEM ALL Geoffrey I can hear 20,000 clearly but 21000 is silently.... Also, these frequencies from each tone (the ones i am capable of listening) makes me a bit dizy and gives me a ear ache.... =S Big Gay Al I'm gay and can hear all of them. 22000 sounds like a lisp. Bankje I'm 21 and i can hear them all. :P anon Anyone know a way i can produce sound samples at any frequency I want like the samples in this page? anon Anyone know a way i can produce sound samples at frequencies up to 150,000Hz? giggleyna i can hear the 19,000 but i can't quite hear the 20,000 ... i'm 19 years old mrdt i can hear all but im only 15 so it dont mean much. i played it during class and all the kids were covering their ears and the teacher didnt have a bloody clue what was going on yipee Im 15 and i could hear all of them. so could my 13 year old brother, 49 year old dad and 42 year old mam. dus this mean we'r weird? :S yipee Im 15 and i could hear all of them. so could my 13 year old brother, 49 year old dad and 42 year old mam. dus this mean we'r weird? :S TheChaddling Im 20 and could hear all but 25k. I mean i couldn't hear it at all. But i showed this to my parents (50 and 60 respectivly), and they could hear the same ones... wierd. Erick Great site i actual can hear all the way up to the 20,000hz its faint but i can hear it SE 40 years of loud music and shooting sports = cant hear above 13K FWK oh my god!!!!! i can't hear 15k above... how can i do now!!!!! Krysta Shastid hi! my name is krysta shastid and i'm doing a science fair project and i was wondering if i could possibly buy or download your frequncies 10,00 to 25,00Hz... if its not a problem... i would really enjoy doing this project.. so if you can let me know as soon as possible if there any possible way of buying them please email me back.. thank you for your patience Mags I am 28 and cant hear half of what people say to me when they are talking but I can hear all of the frequencies except for 24,000 yet I can hear the 25,000 one..what does that mean?lol i can hear all of them but between 18-21. i can hear all the ones after that. i must have dammaged that range of hair cells in my cochlea(how ever you spell that part of the ear) Schimmi I agree with someone up there, these things make my legs weak, wats up with that, isn't that called the brown note? i am at 18 kilo hertz Kameron 40 Male. I can hear up to 17 just fine. 22 makes me want to puke. dennis sir...i think we forgot an important factor... our speaker's or headphones frequency range which varies a lot... some of them doesn't respond to 40khz..so im not so sure if this is a right "test' coz... it also depends on the equipment.. pls correct me if i'm wrong..great site though.. interesting.. gareth heres an odd one. I can hear up to 23 then 24 cant hear but then 25 i can hear? strange. by the way im 34! Iván I can't hear up to 21000 and i'm 17 years old Ruben I'm 21 Can hear up to 24, then nothing at 25. Just fine with me ^_^ I'm 16 and can hear everything except for 18,000 Hz, 19,000 Htz, and 20,000 Hz. Vito I'm 14 and i can hear them all but 19000 is hardest to hear what's up with that? mike one might wonder if our acoustic devices are even capable of producing such waves when they were DESIGNED to creat waves we could hear. What would the practical use of speakers that went past 22hz? pure sillyness. like a DVD that holds 25% extra of information only theres no computer on earth to retrive the data.. Bob I really don't think this test is that accurate. I could clearly hear up to 20,000 using it. I've tried some others, including a Stereophile test disc, and couldn't hear much above 14,000. 5mok I can hear 20,000 Hz, but not 21,000. I'm 18. jose im ten and i can not hear 15,000hz Tommy I can't hear anything because I'm deaf. This is a good discussion. If you can hear. But I can't. Freia I'm a week shy of 28 and with the speakers set at a comfortable level. I can hear 19,000 just slightly, but I also have this annoying high pitch coming from my computer that my husband says he doesn't hear. So that might be throwing me off a bit I should check it out on my laptop which is more quiet. btw I checked out the cell phone ring tone that adults shouldn't be able to hear and that hurts my ears.

Aaron Speakers are designed to turn voltage into sound waves... reguardless of whether we can hear them or not. If your speakers are good (try using a good pair of noise reduction headphones) then this should be an accurate test... given that the sound files are accurate. Debby Work for a school. Kids showed me a ringtone so I came here to see if they were pulling my leg. 13 is my limit. So... they weren't pulling my leg on this stuff! ROFL may copy this and use on my bus route to quiet the kiddies down instead of yelling QUIET... while I trying to drive.... hmmmm ya think? Pay back! btw 50yr old female here bez I'm 15 and i heard 17000 but not 18000.(I'm italian(I'm world champion)) Ruslan I can hear all of them up to 23000 which is an anoying sound. Im 18 years old. Try the lowest. I now have a headack. Im russian. martin iam 15 jears old and i can hear upto 20000 hz but i was wondering can it be that my boxes aren't good enough. because my dog cannot hear abouth 20000 hz thankz. paolo diocane le sento ma mi e' venuto il mal di testa, che dio ti schiacci come una noce... Someone you don't know This is weird, but I listened to sample 2, and I heard the middle of it after it lowered pitch a little bit, but then I listened to the test (I think I have some pretty bad speakers, no ring or anything after 16). After the test, I tried the sample 2 again and I could hear the higher pitched beginning and ending, but not the middle, what is up with that. guy this doesn't have anything to do with this test, but I just wanted to say that reading this entire page at this point would probably be akin to reading "Don Quixote" as far as how long it is in words. Maybe not the same grammar technique,though.:) person what is the approx. frequency of an average dog whistle? Someone You'll do best on this test if you just leave it for awhile, come back and try for a # a bit higher than what you could before. Don't wear your ears out (seriously). ear bugs me i could hear everything up to 21,000 and it cut off; but when i reached 25,000 i could hear it somewhat and it bugged the hell out of me... explains my inability to sleep if a television, ceiling fan, or computer is on nearby... Me... Och that hurt i got up to everything.. but then I'm only 12 years old.. ouch that's still echoing in my ear... How can dogs enjoy that sound? Daniel What you can hear depens absoluteley on how loud you turn your speakers. At full volume I'm up at 23,000 Hz, at a moderate I only hear up to 19,000 Arnas I heard all of them and now my head hurts. I'm 14. Anthony I'm almost 16 and I can hear the 21000hz with the volume turned up no problem. But my ears hurt after. Matt I'm 17, could hear all of them plain as day. Ears feel fine too, got anything higher? matt Hi I am 13 and i could hear up to 19000 hz and my mum who is 29 could hear up to 20000 is there anything wrong with me? randy Hey Im 21 and I guess I got Sonar for ears cause I could hear the 25,000 crystal clear randy Hey Im 21 and I guess I got Sonar for ears cause I could hear the 25,000 crystal clear randy hey btw is it just me but i found this a little weird I was able to hear the 24k better than the 25? im using crappy wireless headphones (radioshack) and the batteries are almost dieng so they get alotta interfierence o and also sorry about the double posts Im not doing it on purpose it does it itself joe age: 22 17,000Hz is ok Ed i can hear up to 23. 23 makes a sound similar to a dial up modem :D española esto es flipante tengo 14 años llego asta 17000 mi madre14000 y mi ermana mayor asta 18000 gavin im 36 and i con hear 22000 hz but hardley jason I'm 24 years old and I could hear up to 19k clearly, I could barely hear 20k but only barely so I'm not going to count it pope master im 15 and i could hear all of them execpt for 24 Francesco I'm 19 years old and i could hear up 20k but i can't hear the 21k, nothing.... w l'italia! me i'll be 23 in feb and i could hear up until 20...i couldnt hear 20 but everything after 20 i could hear just fine however i did get a slight headach afterward i would love to hear what they sound love to hear what they sound like without the harmonies tom i can hear the 18, im 19 year old male. my father 52 cant hear the 10, blames it on too many shotguns and hotrods mmm 20 years old, I got the 18 and thats as high as it goes Ciudadana Herzeleid Damm!! I heard until 17000, and its really anoying. Interesting =D harrison i heard until 25 and my ass is still bleedin fuck CommonRussian I know little of sound, but from my personal sweep tests and spectral frequency analysis, I see what MP3 does to the sound to compress it. When you get down to tests, you would hear a range of ARTIFACTS with altered frequencies, when dealing with MP3, which will undoubtedly give you false results. I find this collaboration highly ridiculous, being a perfectionist that I am. Xenagirl83 I'm 23 years old female and I could hear until 17000. I use headphones.. R-G I'm 17 years old, and I can hear all of them (10,000Hz - 25,000Hz). Blake 24 male, Can hear them all....must be lucky.... beau i can hear all but 17. it is very distant. i am 34/m mason i feel bad for all u suckers i can hear all of the perfectley! im 13 years of age and they dont bother me. i use them for my ringtones at school shawnliau13 i.m 30 m, i can reach to 23000.but a bit low, then hear nothing at 24000 and after Bashir i'm a weirdo, i can hear them all =( i'm 25 years old, i felt like i was gonna lose my mind with those first 2 samples. Taj It was weird that i couldn't hear 24000hz, but I could 25000hz. I'm 14 so ... Perrin I am an English Teacher in a secondary school (mexico)for the past 14 years, I think my job had damage my hearing. I can only hear 19000 Shawn I'm 14 and almost died at 25k. Perfectly clear. Sylvia I'm a week shy of 18 and I can only hear up to 17 000 Hz at max volume. 17 000 Hz is very clear but at 18 000 I don't think i heard anything. Maybe I was imagining it because I'm trying to hear it. I noticed that it sounds like going up the musical scale as you're increasing the frequency. Very cool that going up by 1000 Hz is like going up one whole tone. =) Daniel I can hear until 23000... i have 17 years old Stmeha I am 16 years old and i can hear 25000hz pretty clear Fab from Italy What a headache! Thanks! Btw I can hear all of them except 18000. Weird innit? jonathan I can hear them all i am 17 fred my balls tingled when i heard it Jake Uh I'm 12 and I can hear them all completely exept I can barely hear 19000 and 20000 but still can. It seems to me that my ears feel stimulated and relaxed when I listen to some of them. Oh ya some weird things I can hear in sample 1, are you hear laughing and banging like with a lead pipe on the ground (very low though) z were did u get the spectral analyzer program chris i'm 17 and i can only hear up to 16. holy shit.. playing in a band made me deaf Keith Im 25, I can hear up to 20K but for some reason 19K was more quiet than 20K. Im 20 the cats 19 and 20 made my cat purrup in irritation and leave... Mike I can hear them all... DAMNYOUALL i am 17 and can hear no more then 15kHz Fetusiastic I'm a female and i'm 20 years old. I can hear no more than 22Hz Me I am very very old and can hear just about every pitch. Oh Oh Oh... me im 18 and i can hear all of them... little pickle i cant hear any of them. im 15 and i cant hear ANY OF EM!!! am i retarded?? oh i think its cuz i didnt even download a single file.. maybe thats the cause Lee Henman I'm 36 and could just about make out 17000 with the volume up. 15000 really set my teeth on edge. For the idiots who said they could hear 22000...get a life Bile I can hear 19000, and I'm 17...Do I have a problem with my ears?:) Sasha I can hear up to 20,000. I'm 19. Oh, and I can hear both of those. Masaxgpmat I'm 16 and i can hear up to 23,000 hz Cat Ears I hear the 24kz, wow this amazes me. I guess i'm like a cat help you can download this buy right clicking on the like and press save link as Ahmad Not all speakers ar accurate up to 20K. alot will stop at 15k, and the crappier the speakers the smaller the frequency range. so all a yalls hearing might not suck as much as you think. zack im 14 and i can only hear upto 18000mz Yamila che loco xD Escuché hasta el 22000. I'am 16 Bye! Jake err. my PC speaker Freq response is probably not gonna get past 15khz Gloria I'm 13 and can hear up to 19khz XD Katie I'm 20 and could hear to could feel the detection of 20,000, but couldn't hear it. Otherwise, I can't hear anything above that. noah im 18 and cant hear 21000-23000 but icould hear 10-20000 and 24 and 25 M3TT3 hmm... im 17, turing 18 in less than a month, and i can hear everything... whell, if i turn my speakers up all the way that is :p a wierd note though: i found the 23KHz sound to be lower than the 22Khz sound... now thats strange... i dont know wether its my ears, or just the speakers that just cant make the 23KHz higher than the 22. 24 and 25 KHz still sound higher though... :confused: miky All you guys who say that you can hear the sounds but are adults probably are just hearing the shhh sound, but there is a very high-pitched squeak playing along with that if you can hear it (I can, I'm 11). negus im 15 and i can hear all up to 21000 cant tellyou Im 6 and i cant hear 1600 steven I could hear up to 20000 and i am 21 my father is 60 and can hear up to 20000 Jason Big time harmonic artifacts. I suspect many of you are actually hearing a harmonic artifact below the actual pitch. I can "hear" tone up to 23kHZ, but what I am hearing is not nearly that high. Plus I know for a fact my hearing topped out around 21kHz when I was 20 because I had to work with sine wave generators a lot. There is no way I have developed and additional 2kHz of range. lucas I can hear up to 19000Hz but up to 21000hz i hear a very soft buzz. Josh My speakers' frequency response can't handle anything higher than 20k, so that was detrimental, but after 18,000 I couldn't hear anything. ...and I'm 18. Anonymous I'm 13 and I can't hear anything past 18,000, exept like a really really small buzz. Kenji yea i could here all but 24000 but see how high are teh speakers suppose to go? i put them really loud and i could here all but 24000, it was just silent im 17 BTW louis im 14 and i can here the 25000 but they always said that my ears where perfect (im blind) RubenSP first have a look at the frequency response of your speakers (most of them play until 20khz), and make sure that de player has not some "enhancements" (like winamp enhancer), because they make harmonics at a lower range of frequency... Studies say that most of human ear responsive is up to 16-18 khz. feg:CD player is technologicaly limited up to 20khz ( sample frequency is 44100khz....so 22050 would be the highest frequency--> see Nyquist). Mamid I could hear both of the samples. The first one was more annoying than the second. I'm 34. Autumn I can hear all the way up to 21, then nothing, then 25. Is there something wrong with me? > Madison I can hear all of them except the last one Ben I'm 13 (doing a science project on high frequencies...like this) found this very helpful, and i could just barely hear the 19000 (If somebody knows of a good frequency analyzer, and frequency Generator, please let me know... email ben_gronfors@hotmail.com thxs!) mythik 27trs old and can hear all of them alot of em sound like tv static Vitaly I'm 31, and can hear well all up to 17000 even in a noisy office environment, but starting from 18000 and downwards it cuts off completely. Suz I'm under 20 and I can hear up to 2300 Andi Im 20 years old and I can hear 25,000 Doug I'm 16 and i could only hear up to 20,000 i must be retarded!!! Snow if i can only hear up to 10khz at the age of 15, does it mean i'm dying away faster than everyone else? §ILVERCRØW im 16 and i could hear them all very well except the 25K meow I can meow and i can hear myself.... which is at about 20 hz so... according to my calculations I can hear up to the 18000 jack and jill WE can here up to the 20,000. since our speakers can only go that high, so we found out. Rob I could hear up too only the 14000, and my wife couldn't hear any of them... wiso i could hear up to 19000 i'm 23 and have tinnitus.... big papi 26... i can hear all of em. Mallory I can hear up to 19000 and im 18... now, my head hurts. Lauren I 'heard' all of them except for at 19000 Hz and 20000Hz though I don't understand why those were left out. Below 19000 I could 'hear' and above 20000 I could 'hear'... Oh man, now my head hurts. No pun intended on the 'Hz' and 'hurts'. Though I must say, 20000 hurt the most out of all of them. Anonymous I could clearly hear everything up until about 22 000, after that, I could still hear that there was something, but it was quite soft and not as annoying. andy i cant hear any my computer is to slow i wanna find out i cant try all of the different ones i only can get up to 22000 DP 17 years old and I can hear 17,000 faintly 18,000 nothing else above that Patrick Now i'm a 12 year old child . And since this idea is directed at kids I think I should have a say in it . I consider myself to have a exellent sence of sound (I can hear stuff that nobody can) and the highest I can hear is 19,000 Hz .This just proves that either ... a) The theory doesn't work . or ... b) The people who can here way past me and are like 10 years older than me are lieing to show off let's see what you say to that ;D ! P.S when it get very high I can hear it loud and in a lower tone ..... probably my speaker can't go that high owww well ... Katie I'm 18 and I could every one with perfect clarity, except for 23 and 24. All of them made my ears hurt, especially 25. Maybe that explains why I hearing ringing sometimes and no one else does. Or I've gone crazy. ELW 41 year old female here, and I can only hear up to 15,000. 16,000 can barely make out. Depressing! Lisa I am a 19 year old female. I can hear up to 20,000 Hz comfortably, but knowing that they are there, I can strain to hear the 21,000 and 22,000 Hz. I didn't go even bother to listen to the sounds higher than 22,000 Hz because even though I had the sound on my speakers turned way down my ears felt like they were going to bleed. Kat I could hear all of the pitches...I'm 16 years old though. I started looking at this when a friend of mine decided he was going to put a high-frequency tone on his iPod and play it durring class to annoy the students but not get introuble by the older teachers who couldn't hear it. Of course, I have good hearing and I sit right next to him, so I'm surpised I'm not going deaf...or getting my brain erased on a daily basis. These tones are quite irriating. bojan i`m 16 and i can hear about 19000 but i feel uncomfortable when i`m hearing over 19000 Amber I can hear high frequencies its so annoying my ears hurt and ring all the time after its played sarah i have 12 years old but I can't hear them al Ryan Well, Im a teen, age 16. I can hear all of them including 25K, but not 21-24K. weird. Layla 29 years, female, I could hear all of them clearly, but, I was always told during hearing tests that I had perfect hearing. I do feel very sensetive to loud, or certain noises. i heard it the first time... Dingle Dang I started out hearing up to 16 but then I uped the volume and heard 17 no 18 though...and I'm 27...hmmm Allison Hi.My teacher in my science class used this in class and I was amazed! Its very intereting how it all works. I am 13 and I can go up to 20Hz but i can barley here that it at 20Hz. My brother was also in the room and he could go up to 17Hz when the volume was blasted, so it might also have something to do with volume instead of just the Hz. - Allison Joris 49, i am a drummer 12.000 a can hardly hear and it's more a pain in the head above that no sound, only pain Darla Boles Hey im doing a project over high pitched frequences. I was wondering if you could send me more information on this subject. Thanks gabbi dudez, that's soooo wierd!!! love this site... it showed me what i kept hearing in the middle of class! thanx! nick im 20 male and i can ear all of them perfectly. i grew up in the ghettos basically, lots of gun shots, and i boost up my car stereo and sub-woofers, real loud and i listen to music all the time but i can still here all of them fine. Helder Im 17 years old and I hear 25000Hz v oly I am thinking of using the tones for a school study. Is it Ok ? thank you mystery man First, the reason I checked out this web site is because for many years I have been bothered by an unusual high pitch ringing in my ears, mostly the right one. The ringing is literally non-stop. It bothers me so that often I can't sleep. I'm trying to find out the reason for this and the cure. anyway for the sake of the test on this web site I could hear them all except 16 and 25. 17 was a very low pulsading hum/buzz. 24 a very low buzz. Incidentally, I could still hear the ringing in my right ear simultaneously with those on this test.If anyone can help post it on the world wide web under high pitch ringing in your ears, I'll be checking. Ochen K. Hey Mystery Man, check out http://en.wikipedia.org/wiki/Tinnitus Good luck. Ochen K. Stijn 20 years old, abused my ears a lot. 23 000 Hz is the limit. Luke ive just tested myself i can hear 25000 fine and am 16 i was wondering if you could put any higher frequency sounds up? im interested to see how high i can hear. Missy I am 12, but cannot even hear 17,000. This shows that we are listening to music a LITTLE too loud... Michael I can hear over 25000 and beyond, In fact I can tell if a television is on with the sound off, as well as most every other type of electronic gear. Somebody in my building must have a new piece of gear Because my ears have been ringing/whistling all day, ear splitting annoying with headache. Please Help, I can prove all I've said. Hannes I'm 17, and i can hear the 20 000hz. I can't really hear the 21 000hz, but it does irritate me. Blaine i can hear up to 20000 and thats only if im right there infront of the speaker and 20000-25000 make my ears feel wierd Densets Hey i can hear up to 23 000hz =p btw im 17. katie I have been having trouble watching tv due to the sounds its been giving off, its become so bad i either leave the room or turn off the tv, i try to explain to my friends and collegues ands sometimes i think they think i am mad. I just took the test and i can hear right up to 18 000 kh. Laina One time I was at my friend's cabin and in her cabin was a device that gave off very high frequency sounds (18,000hz?) to repel cockroaches. It was very annoying and they had to turn it off. I can hear 25,000hz but I can't hear 24,000hz. I can hear 20,000hz and 22,000 hz but I can't hear 21,000. Is something wrong with me or the Windows Media Player? chad age 13 can hear all u to 20,000 hz but thats probably because my parents haven't let me have an i-pod or go to concerts ever. I can hear all of them... and my right ear can only hear 80% of the volume (a little desaster caused it), but my left ear can hear 100%. I'm 15 years old and I'm male. On the 25.000 hz I heard paused or pulsed songs and a car engine or something... the song "rings in the back of my head". Horrible... I could hear the annoying sound and I'm 53yrs old! But then elctoronics device emit sounds I can't tolerate. If a TV is up too loud I can't stand it....I got up to 20,000 and could still hear it (my dog could too) the higher ranges made me feel like I was going to get a migraine headache and throw up.....wonder how many of my headaches may be related to sound now. Zaria forgot to ad my info ...i'm the 53yr old... ben dover im 21 and i could just barely hear 18,000. damn my love of loud music. Boy I am very old, but I can hear up to the 25000 Hz :-) Boy2, I am very old still but I canhear 50000Hz Emily i'm 14 years old and i can only hear up to 19,000Hz. i don't get it???? anoniem 22.000Hz 19 year Lennord Lennord, I'm 58 years old, proud father of twelve, and I can hear all of these, but none of my children can. Stefano I arrive at 19 Hz. I'm 22 years old. Bye. Meissal OUCH WHAT EVER YOU DO, IF YOU"RE A KID, DON'T have the volume on full blast when you play it. IT HURTS!!!! Will I'm 36 and could only hear up to the 13,000 hz. Anything over that and I can't hear it, no matter how high the volume. Yes, I have awful tinnitus in both my right and left ears. Lesson for you pups out there.....wear ear plugs whenever you can; cutting grass, using machinery, etc. You don't know how irritating it is to have a high pitch 13000-19000 hz ringing in your ears......24 hrs a day/7 days a week. Ear plugs, pups....ear plugs! Stefano Sorry, 19,000!! I'm italian, we use the point, eh eh. Greetings! pneumoultramicroscopicsiliconvolcanoconiosis I personally can hear all of these. I also found that I can torture everyone in my classroom, including Paige, Sinclair, etc. I am 20. Bobby i can hear up til 20,000, but i cant hear 19 as well as i can hear 20, i am 18 Fran i would like to know if your idea would work for dogs and cats...a high pitch emitting constantly that would drive dogs and cats crazy and keep them away from my lawn and flower beds...my yard seems to be their favorite dumping ground...if you know of any other things that work i would like to know...thanks Elliot 17k is most annoying HM 14 but only can hear till 19,000. OMG! is my hearing havign a problem? hamster im 11 and can hear up 23 three,its really annoying trying really hard to find noise in the other two :) FirexAndxFury I'm 15, and I can hear 25 slightly, just slightly. My mom can barely here 12,000. pretty kool eh? ughur I am 48. I heard up to 21000. I heard hardly at 17000 by bringing laptop speaker near to my ear. Loves from Türkiye. bhk7594 yo i am 12 and i could hear up to 21,000 but at 19,000 it stoped being clear and then the next two were class shattering GenevaStyle I personally can hear all of these. I also found that I can torture everyone in my classroom, Taavi hey i'm 18 years old, and could hear sample 2 and all but 24000 Hz. Don't know why, but i can hear 25000 Hz :( you're lucky if you can't hear the sample 2! it's horrible Kristo Hi I am 16 years old and I could hear everything in this page :D i heard 10000Hz up to 25000 ;) john im 15 years old and heard both the samples but could only hear up to 20000Hz, Taavi's right though, sample 2 is horrible Axis Nice test! I didn't hear the 20000 and up and i'm just 15 :o But ahh well i guess that's quit normal =9 john and i also agree with pea-brain, 1 is incredibly annoying but it wouldnt drive me from a store. 2, however, would have me out of that store faster than i could say ow Tyler Hi I am 14 years old and I could hear all the samples, i put volume on max once it got to the 20's but i could hear them all Frizzly I hear up to 17 and I'm only 16 T.T Jimmy I tested may hole fammly and my yungest fammly member had a headach and did not tell me and at 19,000Hz he can hear it and was in pain so dont do this with a headach it will be veary painfull. sophie I'm 24 and i could only hear 10000Hz, 11000Hz and 12000Hz!! Do i have a hearing problem Centrix 23000 is the highest I can hear, at 25 I can feel something but not realy hear it. im 18 years old Shannon I heard up to maybe 17000 yeah i can tell witht hte tv thing too hmm im posting this on myspace lol Danny I'm 13 and I can hear all of them up to 23,000 clearly, and when I turn the volume up I can hear the last two. Whenever my parents leave the tv on and turn the cable off, I hear a sound like this and am able to tell a tv is on from a different room. My parents can't hear it though Yet Another 13-year-old anonymity I'm 12 going to be 13 in a month and I can hear all the way up to 25000hz. If my speaker's doing what it should, that is. 25000hz is very very very faintly detectable from my speaker.. Chris My wife is a speech language pathologist and frequently (bah-dum *crash*) administers hearing tests. When she runs the tests (the one where you headphones), she and her colleagues *start* testing at 20 decibels. Perhaps a more accurate way to determine hearing threshold, the samples could be increased to something around that range, as opposed to the -6dBs at which they were created. Just a thought from a 35-year old guy who could hear everything except 23k and up, though I had the volume cranked all the way up. :) Charlie Man do i feel good,im 22 and i could hear all the way to 25khz, over 23khz required little more volume though. After abusing my ears this much im pretty suprised. Hannah I'm 14 and couldhear up to 22. My computer skills teacher gets a kick out of playing the ones he can't hear, but we can. It's torture! Keri 40 year old female. I heard up to 21,000 Hz clearly, and felt a sort of pressure but no sound up to 23,000 Hz, but nothing above that. I've always had sort of a slightly odd hearing range though, as a teen I could hear high range dog whistles (which are 22,000 Hz) but I've had difficulty with the low human range all my life, lower bass tones in instruments (especially in electric ones) sound muddled and give me an unpleasant pressure in my ears. I've always listened to music with the bass turned 3/4 down and the treble turned 3/4 up. Good to know I've only lost 1,000 Hz in my upper range. :) Sounds like I'm doing quite good for my age, if most people my age have lost 8,000 Hz in the upper range. anna 25k realy easy and im 71 gustavo im 15 and i can heart up to 23.000! yo mismo its imposible i heard the 25.000 ................ Damm cheap headpones Deafdude Freaky: Left Ear: 11k Right Ear: 13k elbergo weird al dudes, TOM i can go to 19,000 but it bothers my ear till 23,000 Zezima hey anyboy know where i can get the prog. that generates these high sounds? plz post a link. ty Zezima hey anyboy know where i can get the prog. that generates these high sounds? plz post a link. ty jim im 17yo and i can only hear up to the 1600 :( Me I'm around 10-12 and i can hear up to 19 but i cant hear 1500KMz-17KMz (even though i felt juzt as weird as i would if i did hear the otheres) whats with that? im trying everywhere to find out! PS i have pretty sensitive ears. Me sry bout that i meant i cant hear 1700KMz-1800KMz loudly Me ohh and i can hear all of them (20000MKz-250000MKz juzt hardly) Pier I can hear 18000, not over: and I'm 25! Maybe I'm becoming too old! ;-) Meg I can hear up to 19000 and I'm 14 years old. My ears hurt now! Carlos I could hear all of them except 20k.. why? Matt I'm 35. I heard increasingly high pitched noises up until 14000 but nothing at 15, 16, 17 or 18000; then I heard a faint noise at 19 and 20 but nothing at 21 or above. I was listening through windows media player and thought i'd mess around with the graphic equaliser and found that it only goes to 16khz so maybe the player isn’t designed to play anything higher? I'm also colour blind and can't dance - are they linked? Helcio - Brazil I´m 26. i cant hear 24,000 Hz francisco i am 15 and i hear them all but in the homepage of mosquitono i can hear only 3 of them e55 im 17 and can hear up to 22000. Cool website Airz im 17, i can hear up to 19000. i came ere looking 4 info on my science corsework. cool websight Jacson Lamer I'm 19 years old and I can only hear 8000, 9000 and 10000. I tried it on 3 different computers and 5 sets of speakers and got the same result every time. My mother and father always say I am deaf as a joke but perhaps they were serious. I guess the non stop ipod blaring in my ears and guitar cranked full blast without earplugs has done some permanant damage to my earlobes. Kat im 14 and personly I think this wesite is BLOODY COOL!! :D Gabriel I'm 22 and this is driving me nuts. I can hear 22000 pefectly. All televisions produce a high pitched buzzing to me. Can anyone tell me whats going on with my ear? Gabriel clarification: since the files no longer work I could only use the app and that only goes up to 22ooo Hz. I strongly suspect I can hear 25k. mike the links dont work! can u get them up and running again? SpecialEd 37. Have always been annoyed by the high-pitched droning/whining of TV sets. I can usually "hear" a tv screen (if powered on) well before I'm in the room where the TV is. I guess if I really wanted to go crazy I could pay attention to the many different ultra high freq tones that I always, always hear. I read somewhere that these are caused by fluids (lymph and blood I guess) traveling through their respective transport systems under pressure near the ear drum. I used to sometimes hear video cameras (always knew when we were passing a vid cam when riding rides at disneyland, etc.) although now that I think of it; I never hear these anymore, and very new TVs (though not necessarily lcd) are hard for me to hear nowadays. It could be age, technological advances or maybe I just tune it out better now. I like to assume one of the latter two.. (uhhhmm...yeah..) BTW I've never tried a dog-whistle that was actually silent. Are there really "SILENT (to us people) dog whistles"? david is there a reason why every time i scroll i hear a noise? breakpoint Yes indeedy. When your browser is sitting idle, its interference is a nice, high-frequency busy loop. When you scroll, there is a sudden burst of processing to render the now-exposed part of the document. Odds are good you are using the sound output built into your motherboard. Consider using an extern USB device-- and, of course, good, shielded speakers-- for reduced noise from interference. EARTHLING I CAN HEAR EVERYTHING!!! WOOT! Rondo Thanks to the Finnish army I can not hear anything above 15 000khz.. 32 male Thanks a bunch sa int. Lorraine OMG is my hearing decreasing as well as my sight? I know I used to have great hearing. I'm 46 and I can only clearly hear up to the 12,000. I have had tinnitius for a long time... I think it was that Joe Perry concert. Lorraine AAAH! I take it back. I just tried different speakers and I could hear the 13,000. It's painful. Tim I would like to test how high I can hear, but my computer will not allow these links to work. I am only 15 and I am very curious as to my hearing ability. Anyways, how does this determine your ability to hear anyway? I have a keen ear for sound since I play bass and have been in a fair share of bands and dealt with music since I was 10. I could hear both the samples very vividly and they were a little disturbing but I could stand them. I just can't get the actually so-and-so Hz samples to work. cindy I can't get them to work either, have you taken them down by chance? JeffE You need to generate 48k wav files, then try it up to 23,000. They are all quite easy to hear as 44k, as someone mentioned before. You don't get a true representation with digital at 44k. I listened to frequency tones that were not digital. I only went up to 23,000 and I could hear that. I broke up the experiences into two types of sound. I heard solid tones up to about 17,000. Above 17,000 I heard pitched hisses. I'm past 40 years, but my hearing has always been exceptional. I remember a teacher doing this sort of test in class many years ago. I went quite a way past everyone else. The teacher didn't believe me, until I told him when he accidentally changed the pitch. I think he must still think that I tricked him somehow. I think we can all hear higher than we believe we can. It's just recognising those sounds. Sorry to dampen previous posts, but I tried all of these with a 44k wav file and they are not representative of the real sounds. Xenagirl83 The sounds links doesn't works!! Luke im interested in this... A friend of mine has the sound on his phone and he plays it every french and german lesson to annoy our teacher. yes i know...stupid... But the sound files don't work and im just interested to see what frequenceis i can here. could you fix the files? JStormy I downloaded the second sample, i believe its at 15,000 abd all the kids could hear it but not the teacher Jon M/21...I can do about 13,800 in my L ear (slight tinnitus) and 17000 in my right ear...too much drumming, ear-splitting heavy metal, and probably worst of all turning headphones up way too high (creating a ridiculous dB increase). Now I sport earplugs at shows and while in NYC, so hopefully I can somewhat maintain what I got for at least another decade before it begins to slip. dude the only problem is that I can't listen to the samples on my palm max yah that's mine above I think you have a very good content. But your guest doesn't work good... I think you have a very good content. But your guest doesn't work good... james my ears dont hurt and i can still hear good and clear i heard the sound but i couldnt hear my mosquito reppler that makes a really loud nois who knew! Fibonacci I'm 21 and I could hear all the tones clearly. However, I think my sound card might be distorting the frequencies, since the 22kHz appeared to be a *lower* pitch than 16kHz. X I'm 25 but I have some hearing problems that is my hearing is seriously impaired in my right ear, while with my left ear I can only hear up to about 5500 Hz at low db and up to about 8000 Hz on higher db. still I dont have that much of a social disadvantage as I can hear most of the sound that matters. however I can use this for me. if anybody annoyes me such as kids playing outside and disturbing my peace I can just turn on the tone generator and buzz them off :D I don't know, I dont hear them saying "hey what's that sound?", but they just get lost :) A&V hi - my mom and I could both hear sample one and sample two but I (im 12) could hear them at a lower volume than my mom who is 39. We couldn't get to any of the 12000 etc. ones - it just said page not found. Maybe you could let us know what frequencies samples 1 & 2 are? WE'RE CURIOUS! see you a&V andrew i cant even get on there BOBONEEPZ JUST ADDED IT TO MY PHONE. ITS GREAT. I CAN GET TXTS AND CALLS WITHOUT ANYONE HEARING. IM 13 AND I CANT HEAR ALL OF THEM. THANKS! Fred, from England. I don't know how old these comments are, but as one contributor claimes, the methodology is flawed. Here is why... To test hearing, you must generate SINEWAVES without distortion, and apply the drive to reproducers (speakers/headphones) of incredibly high and reliable quality. These devices are horrendously expensive, and are only likely to be found in professional audio labs. The outer limits of young human hearing are 16Hz, the note produced by a 32ft. organ pipe and 20KHz. Much greater sound power is required at the lower and upper ends for it to be heard. The human ear is most SENSITIVE at 3150Hz., right in the so-called midrange. Human hearing "falls off" with both age, and aural damage from continuous exposure to excessively loud noise over 85db. The "fall off" is only at the upper end in frequency terms, and a reduction in sensitivity in the important mid-range. As a rule, the lower end is not affected. Surprizingly, loss of upper frequencies is not noticed until the loss gets near the 3150Hz of the midrange. Remember, the old carbon-granule telephones cut-off at 2,500Hz., and few people had trouble understanding conversations. The bandwidth of modern telephones isn't so good either, 400Hz. to 3,200Hz. is the best you're likely to get. The human hearing system (to include the brain) also compresses dynamically the range of sound intensities, to approximately a log. scale. This is why db., a log. scale, is used to compare intensity. This dynamic range is usually compressed also by broadcasters for their own purposes. The standard dynamic range of human hearing is said to be 120db., that is from only just audible after being very quiet for ten mins., to the threshold of pain as being behind a jet engine at full take-off power. This POWER range is abt 100,000:1. DO NOT WORRY if you can't hear above 15KHz. There is virtually nothing of interest up there; we are human beings, not bats. Even if you can't hear above 10KHz., its not likely to be an inconvenience. However, if you're losing it at 5KHz., then its probable that you've lost some sensitivity at the 3150 point too. Under these circumstances, you will have noticed some impairment. Time to see the audio engineer, and have it tested. Word of warning: Never, ever subject your hearing to noise loud enough to cause "ringing" after you've removed yourself from the racket. Each time you do this, you will IRREVERSIBLY and INEVITABLY lose a few more Hz. of your upper hearing, PERMANENTLY. If you absolutely have to be in a noisy place, wear earplugs or eardefenders. The wax earplugs are by far the best. Cheers, Fred. Audio engineer and loudspeaker designer. Raymond I have a lot to say here. I'll say the important stuff first. I'm 14, and my cutoff is between 20.7 and 20.9KHZ. I can't quite figure it out because my sound card started adding some weird harmonics that made me think I hear 21, and my speakers can even reproduce it, I know it! I used headphones. Above 20, it felt like some force was squeezing my head, but it didn't hurt, had the volume down, down, down! My 14-year-old stepsister can hear up to, but not limited to, 20.4KHZ, didn't go any higher, didn't know what my speakers would do with it. My laptop speakers are crappy, can't reproduce accurate frequencies above 10KHZ, and my 76-year-old grandfather says he can hear it... Now the rest. Most people can't hear freqs above 20KHZ, well I can, but remember, I said most. But that's not what I'm really talking about, I mean 90% of the people on here say they hear the 25KHZ sample, or something within about 1KHZ, and someone said the files had a 44KHZ sampling rate! That's like trying to get 5KHZ out of a telephone! And I don't know the bitrate the mp3s were at, but I tried some things and with 48KHZ sampling, mp3, at 320KBPS can reproduce a 23KHZ tone. And some people want to go higher? Who's posting another comment now that the links are broken anyway? Anybody else who wants to try is going to have to use other software, unless they can find another web site for this (there are many out there). Enough of my rambling! I just like to do it... cabadom Looks great! Easy to find helpful information. Very useful. I will bookmark! tommy The samples doesn't work. Why not? yake I want to know where my frequency threshold was, so I need your sample tones,can you send them to me? I couldn't download any of them. Thank you! My Email is zhouchuang121@163.com Eki yea..none of em working...wht the fuss..im eager to try it... Greg Sample 1 sounded like people in the back ground. Sample 2 high pitched ringing in my ears. The other samples would not down load for me to hear so I don't know what my rang is. I'm 46 apollonia I could hear Sample 1 and sounded quite clearly, with people talking; but I couldn't hear Sample 2, nor could I download the other different frequency samples to find out where my threshold was.. joe The samples of the specified frequencies seem to be disrupted. And actually, keep in mind that every standard sound card in your computer is running with a sampling frequency of 44100 Hz. This means that it will on maximum play sounds with a frequency of 22050 Hz (i.e. half the sampling rate - in case you're interested: Nyquist-theorem in it's simple version). So, anybody who is hearing the 25 kHz tone and is not using a specialized sound card (if you're unsure about that, than believe me, that you don't have one) should maybe see a medicine to get her/his ears checked... ;-) yo i am 44 and i could hear the 25KHz SkH The links are broken!! FIX THEM!! Neighbor in need of your help.......... I need someones help. I have a neighbor that is 80 years old and he has a heart condition. The neighbor on the other side of him has 3 small dogs barking from 6:30am to 7-8Pm. I feel for my neighbor, he always comes over asking for me to help him talk to the other neighbor about these dogs. Which has led it into a neighboring war. Does anyone have a sample sound that buzzes at 55000 to 65000 hz to make these dogs stop barking or to make the neighbor bring the dogs in because their dogs are in discomfort.... I feel bad but these neighbors leave this poor old couple no choice.... Please help...... I'll burn it to a CD and set them up with it looping over and over to help with the dog barking..... dave It actually made my tinitis louder. I'm 41 yr old hypochondriac. Retarted Asshole i dont hear shit im def peter Dead links..... Sorry, comments are closed for this entry.
