‘Mosquito’ Ring Tone can't be Heard by Adults


High schoolers have figured out how to receive text message alerts on their cell phones without the teacher being the wiser. A new ring tone is too high-pitched for adults to hear it.

Called the ‘Mosquito’, a Welsh security company had developed the tone for store owners to disperse young people loitering in front of their shops while leaving adults unaffected.

Many adults develop what's referred to as 'aging ear' and can't hear higher-frequency sounds. As a test, the ring tone was played for a classroom of first-graders — and all of them could hear it, while the adults didn't hear a thing.

Use the vibrate mode. That's what I did when I was in high school.
  by: stonesour025   06/13/2006 05:54 AM     
Can't hear it either
  by: JBish   06/13/2006 10:07 AM     
  any reason why some are and some are not affected?  
i am 21 and i can hear these things. I never minded until i went somewhere with bats last year and i nearly had a heart attack from the horrible sound! while my friends and younger members couldn't hear it except for a 10 year old?
what affects it/ causes you to stop hearing it?

Not telling :)
Can't hear a thing here either.

  Can anyone hear it from the msnbc video?  
I know I can hear the original (security) tone but I can't hear anything from the vid.

For the statistics I'm 25. :)
  by: alt236   06/13/2006 01:14 PM     
  Are you serious?  
Are you guys kidding? You can't hear that "hummmmmm" I wouldn't call it high pitched.. I'd call it a moderate hummmmmmm... Anyway, i'm 24 and work on Jet engines.. If i can hear it, sure as hell the rest of you can! And for the record, no, I don't hear that "hummmmmm" all of the time :)
  by: jljuneau   06/13/2006 01:52 PM     
  im 20 and can't hear it  
all i can here is some bloke counting the reporter in, 5,4,3,2..

  by: fort   06/13/2006 02:00 PM     
  Im 21  
I can hear it perfectly, so perfectly in fact that LOL I GOT A MIGRAINE FROM HEARING IT ONCE! It is the most annoying thing and you can hear it all over the house (its a 5 bed/3 bath)
  by: swordfizh   06/13/2006 02:39 PM     
  I didn't think..  
The audio system of the average cell phone ring speaker would be able to play anything above 3-5 kHz in frequency, well below the 18-20 kHz of a mosquito or a childs hearing limit.

31, I can hear it

  @ alt  
@ swordfish:
thank god i am not alone, dont go to london's zoo bat section, u will loose ur mind.
oh, don't go anywhere with bats.. even if it is just one, it sounds disturbing (i suppose it wouldn't be so bad if you don't mind mice/ rats/ bats!)!!
  by: darkangelJG     06/13/2006 03:35 PM     
  They played that on the radio this morning...  
...on the Bob & Tom Show. Are you serious? You guys can't hear that? I'm 28 and heard it painfully.
It kind of reminds me of a "Pain-Field Generator" except the Hz range doesn't oscillate.
Nice little devices on this site...all perfectly legal, for now.
  by: nonera   06/13/2006 03:35 PM     
  I'm 22, and I could hear it...  
...does that mean I have immature or underdeveloped hearing? Or overdeveloped?

Curious, now.
  by: vanillaskye   06/13/2006 03:41 PM     
You mean its the hummming?
I thought that it was noise in the channel's audio feed from the player they used :)

I was expecting something more high pitched.
  by: alt236   06/13/2006 04:38 PM     
  Whats wrong with you young people?  
You have gone deaf from loud rap music.
I'm 52 and had a slight case of industrial deafness when I was 30(only temporary)since then I had quieter jobs
and my hearing has repaired.
Yes I can hear it quite well and it's
  by: cavador   06/13/2006 04:39 PM     
  Uh the article is wrong guys.  
Its not over 20s.

This is a welsh invention and they have these near shops where I live (I live in Wales).

The inventor made it so only OVER 30s cant hear it (he said 98% of over 30s).
  by: Vistrix   06/13/2006 04:51 PM     
The article never mentions age 20 or 30 or any other age. It just says "adults."
  by: lurker     06/13/2006 04:57 PM     
  @ lurker,  
hey, i am an adult and 21.
this is horrific... so i wouldn't be able to window shop there?!! Agists! =P
  by: darkangelJG     06/13/2006 05:07 PM     
  im 24 and i could hear it  
i beleive it was that static buzz sound
  by: JocKstEelUk   06/13/2006 05:25 PM     
"Whats wrong with you young people?
You have gone deaf from loud rap music."

Are you serious?? Are you really going to jump on the rap music-hate bandwagon. You can play any music loud and have the same effect that you think is causing the hard of hearing "young kids"

I know people in their 30's and 40's that like rap music so, so much for the "young people not liking tasteful music theory" And I listen to ALL music loud and I have great hearing. Selective hearing i will admit to :) but great hearing none the less!
  by: johnnymca   06/13/2006 05:39 PM     
I'm 27 and I can hear it. It's a very high-pitched beep. Everyone in my office ranging from 22 to 37 can hear it. It doesn't seem very selective at all.
  by: Rough Ian     06/13/2006 05:58 PM     
  i am 24  
and its loud and clear, very annoying.

For the record i listen to some rap music and i can hear it. What a ignorant statement to make, you would think people would be "wiser" by the time they hit 52.
  by: sp00ky187   06/13/2006 06:21 PM     
  I'm 62  
I can hear it plainly. Does this mean I'm in my second chilhood???????
  by: PBoxter   06/13/2006 07:00 PM     
  Kids hate it too!  
yeah, at my school some kids were using it to text and almost everybody hated the sound. needless to say, we broke one guy's phone because he wouldn't stop using it.
  by: I_R_Special   06/13/2006 07:10 PM     
  listened to a a couple different versions  
Could hear some of them, not all. They sounded like a TV turned to a blank station to me (blank, not static), the oppresive "whine" of electronic gear. None of the sounds hurt my ears though they did make them start to ring. Maybe my hearing is starting to go =(

I also physically felt some of the versions of the sound rather then heard them. Felt like the was pressure building in my ears, but I didn't hear a dang thing.

I know that not everyone can hear such sounds though. I'm able to hear TVs and monitors that are on but with blank screens from two rooms away. Sometimes I wish I couldn't though, my fiance has a song she really like to listen to but I think the record label accidentally recorded a high frequency noise because there's a background noise to some of the tracks that really sets my teeth on edge but my fiance can't hear it at all.
  by: Dedolito     06/13/2006 08:46 PM     
would teens what a high pitched ringtone on there phones anyway. I like normal ringtones. im almost 21 i might of heard it when it was on the news this morning at 5:00 hour i was watching it before i went into work. I might of heard it but i really wasn't paying that much attention. and also i high pitched noise could hurt your ears so why would people want it
  by: Rachel1085     06/13/2006 10:07 PM     
  Yeah here too  
I live in Cardiff, Wales, and they've just installed it in a nearby Spar. I Haven't heard it personally yet but when I walk past I'll let ya'll know if I here it (I'm 17)
  by: daniel2508     06/13/2006 11:48 PM     
  Heard about it  
I heard about this and I decided to listen to it. I can hear it perfectly. I think the low hummm that some people hear is a sign of deteriorating hearing. The reason it works is because most adults' hearing deteriorate as they get older and they lose the ability to hear the really high frequencies. There are two different versions, the 1st one is higher and much more painful to the ear, the 2nd is the one being used as a ringtone and is bearable.

  I don't get how anyone  
could not hear it
  by: ToofDogger     06/14/2006 08:14 AM     
Here is the MP3 for the sound. Thing is, I couldnt hear it on the news clip, but I can hear this just fine, as could everyone in every age range i tested, except my dad, who's deaf anyways.

My conclusion is, it doesnt work unless your hearing is going.
  by: robplatt   06/14/2006 05:04 PM     
  25 Cant hear it.  
I cant hear it unless I turn it up loud. but another lady in the office 45 could hear it even on low.
  by: imbyjam   06/14/2006 10:39 PM     
inability to hear the sound is caused
by a hardening of the inner ear that
_generally_ takes place around the age
of 26. It really has nothing to do
with your ability to hear things, but
the hardening of the bones in your

I guess you could miss it in a class room full of buzzing fluorescent lights, accompanied by students carrying on... etc. etc. Atleast, that's always been my typical experience in the class room.
  by: Dayron   06/14/2006 11:10 PM     
I can hear the playback in the video just fine. It sounds like the hum of high-power lines or those big green switch boxes you see around factories and what not.
  by: ronny_cordova   06/14/2006 11:38 PM     
Hey Homie ,I didn't say I hated rap music I just said I hate LOUD music.
I'm a big fan of Ice Cube &Snoop Doggie.
Try this=
or this=
Yes I love the game/the cars & the music.
  by: cavador   06/15/2006 01:46 PM     
  i can hear the ring...  
i'm 25 and i heard it, but only after i downloaded the mp3... my co-worker, who is 40, could hear the sound too...
  by: The Rambo   06/16/2006 06:53 PM     
well in that case i retract my last statement to you and still aim it others. :)
  by: johnnymca   06/16/2006 09:57 PM     
  holy crap  
this thing is hilarious. i downloaded it and tried to see if i could hear it. i cant hear jack!! i can only hear it if i place my phone right on my left ear. My right ear -nothing! sad but true. but i have had so much fun at work with it and so far only 1 26 yr old girl can hear it from 5ft away. I turn 25 in Sept by the way.
  by: johnnymca   06/16/2006 11:04 PM     
play that thing on loop in the room/office of someone you dont like. i bet that gets real interesting
  by: reverend j roach     06/17/2006 04:15 AM     
  mp3 vs wav

The mp3 won't work because it isn't a pure tone. Try the wav.

I couldn't even et the msnbc to work because it demands IE6.

For the record: age 30, result negative.
  by: jendres     06/26/2006 04:49 AM     
  I can hear it, BUT  
I noticed it gets much, much more intense if you play with the position of your speakers/headphones. Could be constructive interference, not sure.
  by: caution2     06/26/2006 10:10 AM     
I just my speakers up full volume at work and played the sound, i could hear it very clearly and a secretary across the room screeched "what the hell is that, turn it off turn it off!" :D

I think I'm going to cause some mischief with this :D
  by: koultunami     06/26/2006 01:08 PM     
  34, I can hear it  
It is really annoying... My hearing is not even that great (too many loud concerts and nasty car crashes). Reminds me of some of the old alarm systems I would hear when going into Macy's and such. My parents could never hear it and I always wondered why.
