environment variables would not allow a noise signal to be phase canceled in an open, non-controlled area.
PS: I was dropped to the floor with my eye balls shaking when a Front Of House tech decided to see how low a sub harmonics processor could be pushed on a PA for a 50k seat show. There was no audible sound. He turned the knob three times before we fingued out what was happening. I'll never forgetthe feeling of an audio asult.

Just curious:
If someone can create a weapon using sound waves like that, wouldn't it be possible to create a device using sound waves that would nullify the weapon's effect.
I don't know enough about physics of sound to answer that question. Any thoughts?
Too bad some scientists think nothing of using technology in this sort of destructive manner!
