wcbstv.com - Queens Building Uses 'Mosquito' To Quiet Teens: "QUEENS (CBS) ― Teenagers who hang out inside one apartment building in Jamaica, Queens are getting an earful these days. A new security device called 'The Mosquito' has been installed in the lobby of a building on 170th St. where there have been chronic problems with noisy teens. The wall-mounted device emits a high-frequency screech that can only be heard by people aged 13 to 25. Most older people cannot hear it."

You mean to tell me that there is a "high-frequency screech" that is actually worse than the music they pay for? I don't believe it. Soon that screech will be the most-downloaded mp3 file on the planet.
