Darwin's Theories Are Confirmed...American
Teenagers are evolving into new creatures, for sure.
 NEW
YORK -- (AP) Teenaged students are using a new ring tone to
receive messages in class -- and most teachers can't even hear
the ring.
Some students are downloading a ring
tone off the Internet that is too high-pitched to be heard
by most adults. With it, high schoolers can receive text message
alerts on their cell phones without the teacher knowing.
As people age, many develop what's known as aging ear -- a loss
of the ability to hear higher-frequency sounds.
The ring tone is a spin-off of technology that was originally
meant to repel teenagers -- not help them. 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."

Donna Lewis, a teacher in Manhattan, says her colleague played
the ring for a classroom of first-graders -- and all of them
could hear it, while the adults couldn't hear anything.
