In that old battle of the wills between young people and their keepers, the young have found a new weapon that could change the balance of power on the cellphone front: a ring tone that many adults cannot hear.
The cellphone ring tone that she heard was the offshoot of an invention called the Mosquito, developed last year by a Welsh security company to annoy teenagers and gratify adults, not the other way around.
It was marketed as an ultrasonic teenager repellent, an ear-splitting 17-kilohertz buzzer designed to help shopkeepers disperse young people loitering in front of their stores while leaving adults unaffected.
The principle behind it is a biological reality that hearing experts refer to as presbycusis, or aging ear....most adults over 40 or 50 seem to have some symptoms, scientists say.
So are you curious if you can hear this ring tone or not? An audio clip of it is here. Frankly, I know I can hear it and it's fucking annoying as all getout. I'm not sure how any normal person is supposed to surpress the instinct to punch a person with this ringtone in the face when it goes off. It comes close to rivaling Jim Carey's 'most annoying sound in the world' from dumb and dumber.
