The "Mosquito ultrasonic teenage deterrent" is, normally used as the, "solution to the eternal problem of unwanted gatherings of youths and teenagers in shopping malls and around shops," say its makers, they generate a high-frequency sound that is audible only to teenagers and annoys them.". But enterprising students have discovered how to 'OWN' this unique feature and harness it for there own use.

A group of student have made the annoying tone into ringtones for there own private use, within class. They can text message each other without their teachers knowing.

The catch is presbycusis, age-related hearing loss.

"Anyone turning 20 begins to lose their hearing, starting with the highest frequencies from 18KHz to 20KHz,"

Test your hearing here with the help of the Mazine and remember not to turn your speakers up too loud as you just might pop them ;).
