The ringtone only audible to under 25s

Link: BBC NEWS | Wales | South East Wales | Secret alarm becomes dance track.

A high-pitched alarm designed to repel youngsters from shops is being used for the melody of a dance track after the success of a mobile phone ringtone.

Merthyr Tydfil-based Compound Security released the “Mosquito” ringtone as a way of letting teenagers hear their phones ringing without adults knowing.

It was developed because adults lose the ability to hear high-pitched sound.

But now the sound is being used in a dance track, Buzzin’, with secret melodies only young ears can hear.

You can get the tone via Compound Security‘s site or by visiting Mozzyworld.com.

You just have to text MOZZY to 87070 — the ringtone will cost £3.
