Any Info on Teen Buzz?

[Z Fan]

There's a new cell phone ring that's set at a high frequency that supposedly only people less then 20 can hear. I say supposedly because my father can hear it easily while my younger Algebra teacher couldn't.

The ring was based off of the Mosquito Alarm designed to keep teens from loitering around shops. It emitted a pulsating high pitched sound that is quite annoying to teens but not audible to most adults.

I was just wondering if anyone else had other info or thoughts on this...

It was discussed in the LPE a few weeks back - take a look

Yes. I introduced it. ME!

EDIT: If you cant be bothered to traw through the LPE (If you already have, oh well) you can go on:

en.wikipedia.org/wiki/Teen_Buzz

The links are also good.
