The 'Teen Buzz' Ringtone ...

Amusing.

Bloggers Chat About 'Teen Buzz' - CBS News: "In the age-old battle between teenagers and adults, teens may be gaining ground...at least when it comes to cell phones. In what sounds like every teacher's and parent's nightmare, a new ring tone has been created that many adults over 40 are simply unable to hear. The ring tone is a spin-off of technology that was originally meant to repel teenagers. A Welsh security company developed the tone to help shopkeepers disperse young people loitering in front of their stores while leaving adults unaffected. The company called their product the 'Mosquito.' (Think dog whistle, with a twist.) The ring, named Teen Buzz, is a high-pitched sound, based on the fact that most adults lose the ability to hear high-pitched sounds. It has spread like wildfire over the Internet."
