I’ve read with interest a new ringtone that’s taking teenagers by storm in the UK. It all started with a security company that noticed that they could produce the sound of a mosquito. The sound can be heard by ‘young people!’ – under 25ish. It cannot be heard by adults as hearing gets worse over a period of time! They are now installing the sound equipment in places around the UK to keep youths away from places they shouldn’t be!

The strange thing is now the sound has be created into a ringtone for phones. Children can now take their mobiles to school and when the phone rings, they can hear it, but not ‘teach!’

Amazing stuff really. See if you can hear it by clicking on the link:
