Innovative Students!

The New York Times article, A Ring Tone Meant to Fall on Deaf Ears reports on the ingenuity of teenage students.

A Welsh company has developed a 'yob-buster' - a device which emits a high pitched sound only teenages can hear, designed to allow shop keepers to disperse youngsters without affecting adult ears (apparently our ability to hear sounds in the higher frequency tends to diminish as we age).

Some ingenious teenagers reversed the reasoning behind this device, and realised that it could be used as a ringtone which would be undetectable by adults and so perfect for use during class time!

There's also an mp3 of the sound linked in the article, so you can test the age of you ears!

This story has also been reported in the June edition of Becta's Technews.
