Woow!!! This has to be the coolest audio illusion of all times! Apparently, using the Mosquito device, UK pupils have recorded the ultra-high sound that is audible only to under-20-year-olds. Your hearing gets progressively worse around the age of 20, so if you play a sound on the edge of your hearing spectrum, unless you have perfect hearing, you won’t be able to hear it at all. As I understood, the audio file is somewhere between 18KHz – 20KHz. When I played it, I haven’t heard anything, and thought it was just another internet hoax, but then my 14 year old brother started yelling at me, to lower that sound cause it’s driving him crazy – and he was in lower apartment!! Another thing.. my dog also flipped out! Here is the audio file. Check it out and report your findings!
This effect works best if you put on your head-phones. If the player below doesn’t work for you, download the Mosquito High Freq mp3.
1. Use your headphones if you don’t hear it the first time.
2. Test this mp3 file on your little brother, sister or a dog.
3. Be carefull not to drive someone crazy with this.
4. Test Your hearing here.

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.
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???
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 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…
lol
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.
