I think this is a really cool invention that will also be useful when it gets integrated into consumer electronics in coming years.

Inventor Creates Soundless Sound System

By TYPH TUCKER, Associated Press Writer

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.

Norris said the uses for the technology could come in handy — in cars, in the airport or at home.

That's amazing! Technology keeps advancing, really fast.

PEACE, Mike

Actually...with a little modification, that could also work as a weapon for the military, if you think about it. Not sure if that's good or bad.

That would be such a great way to make people think they are going insane....

that's pretty cool stuff

Wow its like the paperless office only dumber.

That sounds neat. Hopefully it doesn't cause something weird to happen in your brain.

Soundless sound system...........cool!
