Actually, when we first demonstrated the beam device, we used to sit
on the 2nd floor of
a building while grounds workers, below, mowed lawns or trimmed
bushes, or office workers
walked by. Whenever any of them would move in the vicinity of a
concrete sidewalk or other hard surface,
we'd beam a recording of glass shattering at their feet. Because the
acoustic beam reflected
off of most surfaces, when the sound hit the subject, especially at
odd angles, I would have given
anything to have a video camera to record the astonished looks.
