Teacher-proof ring tone latest 'teen buzz'

High-frequency sound can't be heard by most adults--and kids are taking advantage

From eSchool News staff and wire service reports

A technology using ultra-high frequency sound to drive teenage loiterers away from shopping centers in the U.K. has been hijacked by tech-savvy teens to create an inaudible cell phone ring tone. Students are employing the technology to surreptitiously use mobile phones in class by creating ring tones that most adults cannot hear.
