And so it came to pass, on 11-13-96 16:48,
   that Garth Robinson spake unto Sean Dunbar:
 GR> According to some expert or another on the same TV program, made a
 GR> point of the fact that internal organ damage could occur at the
 GR> close proximities. Personally I feel there may be some merit to
 GR> this. Didn't the Germans play around with low frequency horns
 GR> during WW2, apparently a frequency of around 7Hz has pretty nasty
 GR> effects on the body. Is this the bodies resonant frequency, maybe?
 GR> If this were the case then surely harmonics of this could be
 GR> injurious?
Low frequencies can have some pretty weird effects on the human physiology.  
When I saw Orion's demo van at a car-audio soundoff a few years ago, they 
cranked ~125-130dB SPL of something like 28Hz (the lowest note produced by 
the world's largest pipe organ) through that thing, and sitting inside the 
van, I found it difficult to breathe as the sound was causing my vocal cords 
to resonate.  Sufficient SPL could probably stop the human heart.
 SD>> massage when I drive  my vehicle (a pickup truck with the tubes
 SD>> behind the seat) though :-). 
 GR> Nah, I prefer my massages to come attached to a sweet topless
 GR> blonde. ;-)
I hear Fabio's available these days... ;-)
