the big buzz

I heard something similiar to this report on NPR a few days ago or so.

"It was named the 'Mosquito' because the sound resembles that of a buzzing insect. And it works by emitting a harmless ultra sonic tone that generally can only be heard by people aged 25 and under. In trials, it has proven that the longer someone is exposed to the sound, the more annoying it becomes." (text courtesy of BBC article)
