BBC-WALES reports :
"A small Valleys firm hopes its high-pitched alarm originally meant to repel youngsters from shops could become the latest teen ringtone craze".
a high-pitched sound - called mosqito sound - that can be heard by young people but not by adults , seems to be the latest craze for teenagers and their cellphones .
a/t the company , most adults lhave lost the ability to hear high-pitched sounds , so the new cellphone sound can alert teenagers that their phone is ringing without tipping off parents or teachers .
now , isn't that a smart way to use modern science and make some money in the bargain !
it's seizing the enemies weapon and turning it against the enemy - smart thinking !
