Inventor Creates Soundless Sound System - Yahoo! News: "PORTLAND, Ore. - Elwood 'Woody' Norris pointed a metal frequency emitter at one of perhaps 30 people who had come to see his invention. The emitter — an aluminum square — was hooked up by a wire to a CD player. Norris switched on the CD player.


'There's no speaker, but when I point this pad at you, you will hear the waterfall,' said the 63-year-old Californian.

And one by one, each person in the audience did, and smiled widely.

Norris' HyperSonic Sound system has won him an award coveted by inventors — the $500,000 annual Lemelson-MIT Prize. It works by sending a focused beam of sound above the range of human hearing. When it lands on you, it seems like sound is coming from inside your head."
