A ringtone that can only be heard by teenagers
Friday, January 4th, 2008Receiving sms and calls in classes has became easier there are ringtones available which can only be heard by teenagers we call this phenomenon “presbycusis”. This phenomenon is based on our losing ability to hear higher frequency sounds. The high pitch is 18 to 20 khz. So enjoy !!! now don’t ever make your phone silent in class room the ringtone will only be heard by the young ones not your teacher or elders
