Cell Phone Rings Only Young Ears Can Hear
Last Updated:

A high-pitched noise originally developed to keep teens from loitering has a new use. Since most adults cannot hear the noise, teens are now using it as a ringtone that only they can hear.
It may be time to say goodbye to some of those recognizable ringtones. Teenagers have found a tune only they can relate to.
It's called the Mosquito Ringtone, and it's starting to catch on in places where cell phone use isn't allowed. For those able to hear it, the high-pitched tone can be annoying.
There are a number of mosquito ringtones available on the internet, and they'll cost you just like any other ringtone. But those tones are heard at an ear-splitting 17 khz -- more than twice the range of normal communication.
Because most adults gradually lose their ability to hear high-pitched sounds by middle age, the mosquito ringtone can mainly be heard by those younger than 40.
