Someone else also posted an mp3 of the actual Mosquito device from the BBC website and my husband could hear that one. Interesting.

no one will probably believe me, but i hear higher frequency than that. after a while, it becomes white noise, but i can hear my computer on right now (not the fan/disc drive). not sure if it's coming from the actual computer or the moniter. but it can get irritating.

If this tone truly cannot be heard by older people, I wonder if this tone, emitted at extreme amplitude, would be enough to force children to evacuate an area against their will? The comic applications are endless, but perhaps this could have a more serious use...What if such science could be used in combination with today's war technology to reduce the deaths of children in countries with which we are at war. Some sort of warning-drone which would cause children to flee an area minutes/seconds before it is attacked, leaving only adults (sorry civilians). I know it sounds like a dream, but think about it...IF such a tone could cause so much pain to a person under the age of 20 (near deafness type of pain) that it would cause them to run to escape the trauma (it'd have to be so loud that them covering their ears would do nothing)...then you could almost certainly develop some sort of "psychological method" to force them to run in a certiain direction, presumably away from danger. Hey, if it could save at least one child, then it'd be worth it.I know this was somewhat off-comment, but I felt I had to share that idea. :P

If you could post that it would be awesome. Or i could make it myself, but I've got finals. I am too lazy.

I've heard of mosquito repellents <a class="user" href="http://www.allrepellents.com/">http://www.allrepellents.com/</a> but this is too funny. Amazing what they'll do to be pests..

This is very stupid really. I'm 26 years old and can hear it perfectly!! Maybe it's because I don't hear loud music. And never use headphones.

it sounds like somone forgot to shut off the TV

You should be able to hear it if you're over 20, but teenagers are more sensitive to it. I remember on the news it said adults can only hear it from a few feet away but teenagers can hear it over a hundred feet away. If you're right in front of your computer and your speakers are turned up all the way, of course you're going to hear it.

Cell phone speakers can very well reproduce frequencies above 18000 Hz. It's a known fact that to reproduce high frequencies, all you need is a small transducer (ever wondered why the tweeter in your speakers is smaller than your woofer?) and very little power (because it's got to do much less movement of air, compared to a woofer).Think before you write.

Of course, encoding a 18000 Hz sine wave onto MP3 will incur in frequency lowpass with most default settings in MP3 encoders (effectively rendering your MP3 without any sound). And if your phone only plays AWB or AMR, you're pretty much screwed because those only capture voice-range frequencies.Think before you write.

If I put the wave file on my Nokia 6600 it cant seem to repriduce the sounds. I hear a loud sound like that of a dialtone. not the ultra high pitched one.. Why is that?

Number one, if anyone is still reading this, and number two, still has the crazy idea that this isn't for real, (or is worrying it won't play on such and such a speaker) then guess what? Proof.11/24/06: Ig Noble Prize ceremony is being broadcasted on NPR. They play the sound (Mosquito got an Ig Noble prize, by the way) for added drama, asking seven under-age audience members to come up on stage. When they play it, the seven (and other under-age people there) react. Older people are thinking "Neat!" or "Did they tell those people to react?" or "Weird.". I could hear it, too, over not very high-quality speakers.And my mom? "Are you pranking me?" (No.) "You could seriously hear that?" (Yes.) "You're not just trying to make me feel crazy?" (No, that's just your crazy ears.) Ah yes, and 20 year olds saying "Ooh, I can hear it."? YOU'RE SUPPOSED TO. It's 22 and under.If you can hear it and you're older, then maybe it's a crappy version, or your speakers are whacked out, or you have mutant ears. :)

I'm 12 and I heard it--it hurt!

I just found a number of different frequencies and formats at <a class="user" href="http://www.teenbuzz.org">http://www.teenbuzz.org</a> - quite interesting to see if you match the proposed age group/
