My daughter and I were talking Friday night and she clued me in on the latest cellphone secret in her high school... Teenagers have started to use a high-frequency ringtone that, apparently, adults are unable to hear:

"In settings where cellphone use is forbidden — in class, for example — it is perfect for signaling the arrival of a text message without being detected by an elder of the species.

"When I heard about it I didnt believe it at first," said Donna Lewis, a technology teacher at the Trinity School in Manhattan. "But one of the kids gave me a copy, and I sent it to a colleague. She played it for her first graders. All of them could hear it, and neither she nor I could."

The technology, which relies on the fact that most adults gradually lose the ability to hear high-pitched sounds, was developed in Britain but has only recently spread to America — by Internet, of course."

COMMENT if you can hear anything!
