Mosquito Sound Repels and Attracts Teenagers

Mobile phones

In one of those bizarre technological twists a device that was originally designed to repel teenagers, stopping them clustering together and making nuisances of themselves has morphed into something that teenagers are now clamouring for. The device is called Mosquito and it emits an irritating high-pitched noise that only teenagers can hear. Now the International Herald Tribune reports that the Mosquito sound or ‘Mozzytone’ has been transformed into a 17kHz ringtone, or Mosquitotone, audible only bats, teenagers, dogs and a very few supple-eared adults.
