The Mosquito – kids can hear it, most adults can't
Ok, I’m a little late, almost 2 years late, but I just heard about this and think its really cool. I read this article and this one is also good, and got curious, so from there, I came across this link which will let you download a tone generator with which you can generate your own custom tones and test your hearing abilities. I tested myself and can hear up to 18Khz (18000.00Hz), but nothing over that. So I should be able to hear the teenager mosquito ringtone just fine, which is around 17Khz. I could hear all the sample sounds out there on the internet, and with the tone generator I mentioned, I found the limits of my hearing abilities. Just a warning here that listening to these tones is annoying, its not a pleasant sound, and leaves a bit of a ringing in your ears. I would advise moderation here when playing around with it.
