They always find a way...

Some students are downloading a new ring tone from the Internet that's too high-pitched to be heard by most adults, allowing them to receive text message alerts without teacher knowing. 

(One teacher 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.) 

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 a Welsh security company developed to help shopkeepers disperse young people loitering in front of their stores while leaving adults unaffected.
