Woody Norris HyperSonic Sound speaker article

["Adam Liberman" <>]

This is a very interesting article in the NY Times on an invention 
by Woody Norris "...called HyperSonic Sound (HSS). The aluminum 
plate is connected to a CD player and an odd amplifier -- actually, 
a very odd and very new amplifier -- that directs sound much as a 
laser beam directs light."

Sounds like an interesting concept. I wonder what a bird would think 
about this used for field playback? Or using it for localized sound 
playback in a museum exhibit. (I'd think that there would be some 
dispersion inside a room once it hit surfaces, even if the sound 
eminated in a beam).

Anyone know more, or if this actually works?
