I wonder if it will work on a target 100 m away. If
it only works up to 100 yards away, that is like saying that it won't work up to
100 m as 100 m is 9 m farther than 100 yards.

Woody Norris wants to tell you something�and he can put the
words inside your head from 100 yards away. Is his invention sound, or
just a pipe dream?
The Hyper-Sonic Sound System (HSS), as he calls it, can take an audio
signal from virtually any source�home stereo, TV, computer, microphone,
etc.�and convert it to an ultrasonic frequency that can be directed like a
beam of light toward a target up to 100 yards away. |
