"What's the Buzz? Rowdy Teenagers Don't Want to Hear It"

[C]hildren can hear sounds at higher frequencies than adults can....

The device, called the Mosquito ("It's small and annoying," Mr. Stapleton said), emits a high-frequency pulsing sound that, he says, can be heard by most people younger than 20 and almost no one older than 30. The sound is designed to so irritate young people that after several minutes, they cannot stand it and go away.

So far, the Mosquito has been road-tested in only one place, at the entrance to the Spar convenience store in this town in South Wales. Like birds perched on telephone wires, surly teenagers used to plant themselves on the railings just outside the door, smoking, drinking, shouting rude words at customers and making regular disruptive forays inside.
