Wow... I just loaded the first file into goldwave (an audio editor), slowed the playback rate ever-so-slightly, and suddenly you can hear an intensly irritating oscillating whine all the way through it. Clever stuff!

Fantastic. The last one's the best. Really made my heart flutter.

Well, it's not exactly at 20 years old. I'm 26 and I hear it quite clearly. And I play in a band, and should be deaf (not really- unlike some bandmates (read: all of them) I use earplugs).

lol! I heard the first and the last file. In the first file I didn't hear anything. But in the last one I think i heard something! :P

I'm 25 and can hear it ... but that's really a nasty sound ... bless you who can't hear it ;)

I'm 25 and I hear it. Interesting, it sounds like the tv when my dad think it's turned off but it really isn't. He does it all the time and drives me mad. He is actually just turning off the decoder, so the tv is getting no signal, which it makes it looks like it's off, except for that damn crickety sound!! I should be more forgiving, it's not his fault that my dad is old and deaf...

Hey whats up with the last clip from ebaums world its some guy saying he likes porn... how wierd.. but i just turned 20 and i can hear some of the stuff.

is this some kond of joke ??on the first 2 i can hear a high ton, is that it ?? the rest are just people talking and background noises or r u supost to hear a high tone there to ?? the 5 one is totally wierd talken some shit about gay porn wtf (joke to freak people out or what??) ??

I am 25 and I can hear the noise no problem...

I'm 25 and can hear first one very slightly. Can the people who can hear it also hear that high-pitch CRT TVs put out? I always know when one is on, even if it's in a different room.

Well altough it is a good Illusion to say, but i guess are not correct about the age limit u mentioned. I m 23 yr old still i can clearly hear all the samples. But i'll have to say that it was a good move, out from "opticals". Keep it up. These samples are good collectables. thnx.

I'm 44.

Clip 1: I don't hear the mosquitto.
Clip 2: I don't hear anything but an occassional click.
Clip 3: just leads me to the rapidshare site. I didn't download anything.
Clip 4: is a Torrent file. I don't have anything that plays it.
Clip 5: Loud and clear
Clip 6: I don't hear anything but occassional clicks.

Nice one. My little sister and I could both hear it, but my mom couldn't.

And you guys are all right, it's the exact noise a regular TV puts off when it's not playing something.... actually, it always makes the noise...

I only did the first and second as I listen to high pitched sounds to my reciever (no I'm not a pro at it) and I can detect in to a really high range.


That being siad.

#1 I can hear the sound but it doesnt' sound like what I'd consider high pitched, although winamp shows that. However the peoeple in the back laughing and the two clicks, are they supposed to be there do you know?

#2. I though I could hear #1 so I turned it up then I read duh use earphones and... OUCH! that hurts. Didn't do the rest.


I've read some comments and what not and I don't think I want to play that at work.

there was alot of talk abou this on digg.com, link: http://digg.com/technology/Teenager_repellent_Mosquito_turned_into_ringtone

if you like playing around with this stuff, download audacity at http://audacity.sourceforge.net and try it... open Audacity...

Generate > Tone

Waveform: Sine
Frequency: 18000.00
Amplitude: 1.00

Wow they should make little kids shows in that frequency somehow so people dont have to listen to them.

Why is the fifth one for people under 20 years old? It's just talking about porn! I'm omly 11, and I really thought it was inapropriate! And at the end when the guy said he loved gay porn, my volume wouldn't turn down. And my family could have heard it! But the rest was cool.

I apologise greatly. I didn't know the content of the last one. Gonna remove it imedately. Thank you for your info, and please don't be offended, and I also appologise for your embaressment. It won't happen again.

Interesting. I am 32 and nada.... but I can hear monitor squeal very clearly.

I'm 31 and I can hear all of them. When I played the first one with people talking in the background, I could hear the high pitch sound pierce my head right through, it made me cringe... Ouch

damn this is the dank sh*t

that sound gives me an instant boner

I am 26, I can hear all three of these tones, It was a painfull even to them on just for a few seconds.

I am 33 and I could hear them all - especially the first 2. I could hear the last one but it made me feel wierd.

1st one didnt run on my phone...
but 2nd and 3rd i did hear it. :D

Im 35 and can hear it fine

AMAZING! how do i get this as a ringtone?

I'm 20, and I had a hard time hearing it due to my tinnitus. I had to turn the volume up before I could hear it, but I could feel it before then. The tone emitted matches the tone I hear in my head all the time, so if you want to know what I put up with every day... I'm not saying that I suffer from it.

I'm 24, I do SQ (Sound Quality) competitions with my vehicle, I tend to hear stuff others dont, I also can hear the TVs, some of my computers give off the exact same whine (not the monitors) but when the monitors do I go nuts trying to fix them and everyones like "what are you talking about? I dont hear anything" I couldn't hear anything but the people in the first one but the speakers on this computer aren't that great, so I thew it in my truck, holy crap! it actually called some dogs!

wait a minute.. does this test work on deaf people?? cuz i seriously don't hear a thing.

I'm 23 and deaf in one ear, but I can still hear it just fine.

omg i am 14 nd the third one drove me craZY I WENT INSANE ND MY DOG STARTED barking.. lol

I'm 17 and heard all of them clearly. My brother is 25 and hears them all clearly. My parents walked in and didn't hear a thing... i'm gonna try playing the third one (most annoying sound) in class so everyone will complain about the sound but the teacher won't understand what's going on =P

Wow. I could hear the second and third ones very clearly after putting my volume up, ( I could hear them slightly before that), but the first one wouldn't play (the play buttton wouldn't show up). I'm 12, for those of you wondering.

I am 32 and I hear all 3. When I was in high school we did a test of sound wave systems using a sine wave generator and a couple super speakers capable of pruducing ultra low and ultra high speakers to show the effects of what adults and kids could hear. When we did the tests 3 of us got singled out for being able to hear quite well, in fact more than the others. I was able to hear to a very extreme range and got almost to a point where a dog could still hear but not quite all the way. I have heard these sounds for years and have complained about monitors and certain electronics. I could even pick up hums off of transformers and dog reppelent toys even those little mosquito repellers can annoy me if it's put up right to my head. So I thought this was pretty neat, and it's nice to seethat even though my hearing has gone a little I still have pretty good hearing.

I am 21 but I can hear two of the sounds (2 and 3) but nothing on mosquito...

Wait, if I increase the master volume I can hear mosquito sound too !

This is awsome! Just how do you put it on your cell phone- (Need Directions) - like how do you get it as a ringtone using it as a download... If someone can give me a link or something Please. I have a SLVR. Thanks!

I am 14 and I can hear them all and so can my 12 year old brother and my 7 year old sister. But my dad and grandma can't hear it. I think my cat heard it.

I did some research and it is audible to people 25 and under, normally.

If you do some research... For the average person, you will be able to hear the sound until around 40 years of age. Anyone under 40 should be able to hear it. I'm 33 and i heard it fine, although who the hell wants that for a ringtone?

im 15 and i could hear all of them, what i need to know is how you get these on my cell, i could put these to use

Wow! I'm 12 and I can hear it, though neither of my parents can. My cat was flipping out to!

i am 14 and i don't think i can hear it

u people are reeeeeeeeeally stupid to just give away your age. dunno y but thats what my dad sys

That's very cool! My 45 year old uncle could not hear it no matter how many times I played it.

Hey Seba 719 how could anyone use your age to stalk you on a website where you can post using a name you just made up? It would be stupid if you also put your real name, address, phone number, social security number, and bank account pin; just one would suffice to be classified as acting stupid though.

In regard to the files: I am 15 and in file...
1) heard a quiet whining (plus the background people)
2) a very loud screech that made me cringe anf immedietly stop the plyer
3) was kinda afraid after what happened in 2 but i couldnt hear anything when i played it; releif and dissapointment at the same time.

YO! IT DIDNT WORK AND IM only 11 !

yo i heard it but all i heard was sum retard gigiling

This just proves that teenagers of today have bad hearing ... or mainly just me.. I'm 17... I couldn't hear anything in Frequency two. In Mosquito one.. I can kinda hear laughter and backgroun noise.. as if I were in a cafe or something.. and the third one wouldn't download... So yeah I dunno.

COOL IT WORKED and when I turned it up really loud the dog across the street started barking! Maybe it was just a coincidence, but still REALLY NEAT

wtf thats reallllllly weird i could hear it my sis could hear it and it hurt our ears but my mum and dad and all the teachers at school couldnt cooool

I really liked this one a lot. I thought it was really interesting.


My dog was leaving the room when I played the third one and he turned around and sat next to me, growling. I stopped it and he layed down, now calm. I played it again. His ears began twitching quickly. I moved the computer closer to him, as soon as I did he hopped off the couch growling.

I'm 13, and heard all of them. Very shrill, made me cringe. I'm interested in seeing what my mom says. But wow, seeing my dog act like that was insane. Good work.

im 12 and i can hear all of the sounds and my dog died when he heard it

Do you people realize that this is IMMPOSIBLE? The freqency of a sound that old people cannot hear and young people can would have to be approx. 20KHz. The MP3 encoding does NOT play freqencies above approx. 15 KHz. That is one of its features that make the file size so small. To actually play a 20KHz sound it would need to come right out of a speaker with NO encoding. I sugguest you download the Open Source Program "Audacity" (I believe it is available at sourceforge) and generate a 20,000Hz Tone.

there was just a story on ABC NEWS about this. the cutoff age is, on average, 25 years old. thats why you 25 year olds could hear it. as for those older than that, you are lucky. it is quite an annoying sound. they are using it now to keep teenagers from loidering, and teenagers are using the tones as cell phone rings in class so that their teachers cannot hear it. haha.

The mosquito one make my head hurt so much!!!!

OMG they all make my head hurt SO Much!!!

I played one of them and my neighbor's dog got in trouble!!! I feel so bad!!!

I played the first one and it made me nausious and dizzy. Then I played the third one and I immediately jumped to the mute button. felt like my brain was melting and i thought my ears were bleeding lol. I'm 26.

I'm 38 years old and I hear all of them with no difficulty. They are incredibly annoying. I guess this means that I have better than average hearing.

My 60 year old father heard all of these without a problem

that was easy to hear, the first one sounds like there might be cars in the background and there are definatleyy two women laughing. the third one really hurt my ears!

i can hear it. my mom can hear it too. she's 40

i'm 33 years old and i can hear it too!!
Still young!

Oooohh...... Those are horrible! I can hear all of them. (I'm eleven.)

I can only hear the first one, and I'm 14.

Yeah, I'm almost 40 and I can hear #1 and #2 clearly, but #3 I can't hear, but it gives me one heck of a headache. Might explain why I hate being around some electronics, it just makes me feel "oppressed", but I could never explain it. Also I've always hated that stupid high-pitched tv whine.

I'm 23 and i hear them all perfectly.
My mom and dad (both a little over 40) can hear 2 and 3, but they can't hear 1.
It looks like the sound some TVs and video players make X_X but not so bad. A lot of those sounds annoy me sooo much x-x;

I am 29yrs old.and I heard some voices on the 1st one,#2nothing,#3 nothing...my 4yr.old daughter said she heard all of them,the last 2 she heard a flute sound,she was down the hall way too..I dont hear nothing!!dam it!!very weird!

I tried the first one and I'm really confused... I couldn't hear it when I played it in iTunes, but then I tried opening it in Audacity and I could hear it. Maybe my settings alter the file in iTunes???

dncxo mckjt svmtuj dzvexmryw upmztdiw uzbnefcko ymzw

that made my head hurt!
the first one i heard the stupid noise and girls laughing
the second noise i hear stupid buzzing
the third i hear the noise...really loud

o by the way i'm 13 years old

This is really cool. Does anyone know where I can get this for my phone? I use verizon.

i told my mom and step dad to listen to it and they said they didn't hear it.Me and the rest of my siblings heard it though.

Well, I can hear it, I'm 16. But my father can also hear it. He's 46 and is almost completly deaf on one ear. But maybe it was just because the volume was turned up quite high.

The hell, my mom's 42 and she heard it. o_O

Dedra
I'm 46 & only heard the first 2...Guess I'm a goner!

yes well im 16 and i can hear the 1st one easily second one faigley and the 3 one not at all. hmm :?

COOLEST THING EVER!!! I've always had good hearing, and each one of those horrible whining noises made me wish I didn't. The dog, however, didn't care.
My fiance thinks I'm crazy, incidentally.
I agree that it sounds like the noise a TV makes when the sound is turned down.

that is really weard on your ears its like a dentist drill its horrible im under 20 fyi

i can hear the first one clear as anything and i'm 24, but i can't hear any of the others :(

Ouch! The first one REALLY hurt my ears. I could hear it really loudly. (I'm 14) Really cool though, I don't think I ever heard a noise that high-pitched. If youre under 20, I warn you, this may cause serious damage to your ears (or atleast I think so...)
Hahahaha

I'm 11.7, and so I don't know about when I'm older yet, but my dad does the same thing! I can hear all three clips. I too, hear when the tv is on. Or old monitors. I wake up in the middle of the night just because of it, when I wouldn't wake up if you dropped a book. It must have to do with that frequency... Also, my bro is 20, and he hears this. (Then again, he's only been 20 for about a week...oh well.)

I am about to turn 10, and the first one doesn't hurt at all. I have very good ears and eyes. Even nose! I havn't done the others yet.

um. . . the REAL cutoff is 30. so i dont really get why some ppl over it can hear it. oh well. lucky you. i'm 14 and the noise was always being played in my class at school! REALLY ANNOYING! but it was a passing fad and no-one plays it anymore (here in the UK.) x X x

That thing kills my ears i can hear it but i think i am going deaf becuase of it

OMG this is so cool I'm 13 and I can hear it really really loud. the 1st one isn't quite as loud as thee rest but man the third one is so awsome. My ears are still ringing.

Ohmigod my hearing is terrible.
I'm 15. I only heard the first one.
But on the others, my body responded to the sound (my ears hurt and my throat went weird) rather than my brain, so I think it's only JUST out of my hearing range.

I am 23 years old and when I turned this on it hurt my ears sooooooo bad

im 13 and i hear all as a really loud. ive actually got the last 1 on my phone and i play wiht repeat on in class drives every1 nuts. they all like aaaaaaah my ears but the teachers hear nothing.

Rediculous, computer speakers dont go that high in KHz, my parants can hear every sound that i can cuz theres a cutoff , we hear high pitch noises to a certain extent, no wonder so many ppl hear it. unless you have extravagant speakers that go well beyond the human hearing range (a rediculous extravagance) no one should hear what they 'intend' you t hear.

im 11 and i heard it
my 4 yr. old sister also heard it
realy anoying by the way

My mother wich is 34 ear it Maybe some adult people can

I couldn't hear #3 but it sure drove the dog crazy! And FYI, I'm 46. Guess it works. I'm gonna send it to both my daughters (21 & 25) and just ask them what they heard.

Kissyfurr

I'm 14 and can hear all three. does that mean i have very good hearing?

I was able to here all dependingon where I was sitting in relation to my speakers for my pc. The first one had to be really loud for me to hear it but it is a really high pitched noise. It actually hurts my ears-- all three sounds. And just so you know-- I'm 27 years old and a female-- I dont know if that makes a difference but I thought I would let you know.

High Freq 2 mp3 file sounds like the sound inside my head when it's really quiet around.

Well, I turn 44 a week from Saturday and I heard all three, but then again, I am paid to hear in the higher frequencies anyhow. I will say this however, it is not just dogs that go crazy over the sound. I have 2 grey tabby cats and both of them came running as soon as I started playing it.

This doesn't work...my dad could hear it perfectly and he's over 50!

it does work, my mom couldn't hear it, but I could! same as we have an waterelement in our kitchen, when its turned on, its only me and my sisters who can hear it, and my mom refuses to turn that damn thing off...

I am 29 and I can hear all three...the last one I can actually feel in my head and face, very uncomfortable. Anyhow, interesting, thanks.

I thought that this was sooo cool... at first I did not hear it, but then I turned up the sound, and my heart jolted. It was sooo cool.

that is so weird i could hear this high squealing sound but its really quiet im 14 and my 3 year old sister kept covering her ears and telling me to turn it down

OUCH!

So I went to this site:

http://www.jimmyr.com/blog/hearingloss.html

He's got multiple frequency sound samples with which to test your hearing.

I'm a 35 year old female, and have always been able to hear the high frequency CRT monitors put out -- can be maddening.

So I tried the samples out on headphones and on separate speakers to see if it was because of the headphones or speakers, but someone explain this one to me:

I can hear -all- of the frequencies up to 22,000hz; _however_, it's harder for me to hear the 15,000hz to 19,000hz range.

BUT, above that -- 20,000hz, 21,000hz, and 22,000hz -- I can hear far MORE easily than the 15,000hz to 19,000hz range.

So I guess my hearing is diminished in the 15,000hz to 19,000hz range, but is MUCH better in the 20,000hz to 22,000hz range? Very odd.

Also, on the sound files on this site, the mosquito one is harder to hear -- I mainly just hear the people in the background but hear an occasional flutter of what might be the high-frequency sound, the rest are extremely easy to hear with no issues.

What gives there? I would like to try above 22,000hz -- that was easy shmeasy.

I'm 15 years old and i cant hear anything

I'm 28 and I could hear all of them. My mother, 50s, could not, but my brother who is 26 could not either. I never realized until now that everyone else doesn't hear the noise from the TV.

Im fourteen and i could hear them all perfectly

my grandfather who is 52 couldn't hear anything

im glad im not the only one who knows when the t.v is on...i'd alwaus be able to do that and my friends thought it was freaky lol

I'm 27 and I heard them. the mosquito ringtone was easy to hear, the other two were at the edge of my hearing range and I had to get in really close to hear them. Before i actually identified the sounds i felt the change in pressure in my ears. I don't know if it's just me but I am extremely bothered by those high frequency pest repellents you can buy. someone up the street has one and every time i walk by it drives me up the wall.
