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.

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.
I’m 13 and heard the first and second one very easily, but the I had to turn the sound up a bit on on the third.
COOL AMAZİNG! CREEPY! BUT GOOOOOOD!
Hey when I saw this I thought wow thats cool, but I tried in on my parents who like way over…I’ll say 40 ;p and they heard it I’m 19 and heard it so yer…but it its like on the news lately bout some councils putting those alarm things up that only under 20’s can here must use a different wave thingy
I’m 12 and I heard them all and they played them on the radio and Dad thought I was tricking him cause he couldn’t hear it and now my ears hurt.
So, I’m 49 and I can here it, with or without headphones. Yes, I DO want a medal…
i cant hear it..
i can hear the first one, the voices of the people at the bg..
i guess its bcoz im listening 2 my ipod everyday on my way to school..
i’ll tell this to my friends..
(mahina ata pandinig ng pinoy)
hehe..
i just turned 20 last sept..
geez..
Well, at 54, could sorta hear something if I put my head close to the speakers, but after playing it three times, I’ve got a weird ache in my ears (which ring constantly anyway). Entertaining to try though.
it definitely sounds like a television buzz…or that sound you hear while near some serious electronics…I’m 30 and hear both clearly i guess everyone hearing degenerates differently electronic buzz used to keep me up as a kid
i thought u must be crazy to no be able to here the noise(of what might be coming from the wings that sounds like clashes) so i downloaded it and it no longer played clashes but a high feqence noice that on top of harming my ears i had my younger brother freaking out down stairs…my mom thought he was nuts!lol
i am 37.. i can perfectly hear it and it drives me crazy.. i used to hear the same annoying sound in my childhood all the time when TV was on (old tube televisions) and the first computers had the same sound effect.. your could torture me with this over time
Woah! The mosquito gave me a pounding headache! Thanks :)
*Shudders* I HATE that noise. I’m under 20 and I can hear it but my Dad can’t. also when I played it my dog was walking and she just stopped dead when she heard it and started looking at the computer.
i’m 27, play in a band, attend too many loud concerts but i can hear it at low volume without earphones. i started using earplugs only recently (which i would recommend to anybody!)
i FEEL -20, maybe that’s the trick ;)
I only see the mosquito one, where can I find all the other ones people are talking about?
I heard the mosquito noise, but so could my dad, who’s 52.
I’m 21 and I heard it. Yikes! Sounds like whenever a television goes on.
No one else in my family can hear this… I let my 6 year old sister listen and she couldn’t!
I also can’t stand the sound TVs make. Sometimes I notice it and it drives me insane. Other times it doesn’t really bother me. People who can’t hear it are lucky! lol
its like, not a sound but more of a ringing kind of feeling in your ears.
Annoying. Very annoying. When should I be not capable hearing that? I’m now 20.
OUCH! Me and my dog flip out! its hurts
OWWWW!!!
I’m a 40 year old mail but crikey that hurt. Was stabbing to find the >stop< button.
Phew
My brother and I can hear, and we are 20 and 28, but our parents don’t XD
My dad is 40 and he can hear it
how do i download dis??
man..how can i hear it or download it.when i try save target option only a 300+ KB file is downloaded and that too is corrupt.
when i click on ‘hear it’ i m directed to some other site.does somebody have an answer?
OMG thats soo cool I tested it on my moms bf and he couldnt hear it I am gonna test it on my mom when she gets home too
I can hear the 30Hz at roughly 36dB. I can’t hear the 16kHz at all… I heard the 12kHz at 45dB. I can hear the mosquito MP3 thou really soft, it still hurts my ears… I’m 21, by the way…
