Meanwhile, I swear I've been to performances of a large pipe organ
that produced low notes that could only be felt as vibrations. I also,
have always wondered if our senses detect very high sounds, but
process them differently than what we consider "audible".

Low frequencies in that range are sensed by conductive hearing (through
bone
mass in the head). I can get more info about the specifics from my speech
pathologist ex-wife, if she deigns to speak to me this week. :-)

So those with more bone mass in the head would hear those frequencies
better.

Hmmmm - brings new meaning to bonehead doesn't it?

Actually, the standing belief is that "we dunno". Believe me - I've asked.
There were times when my son and I were talking about a great bass line in a
song and she'd say "Where? I don't hear it". And she's got perfect hearing,
too. I think it's a question of what you focus on, and how that can train
your attention in ways that are hard to change.

Lower frequencies can be felt, but not heard. There are conceptual
weapons
that broadcast high power, low frequency sounds that can kill or
incapacitate the target. There are many cases reported of people being
ill
from low frequency noise in buildings. And if it is Memorex, you can
break
wine glass. ;)

I wonder if this can be turned into a weapon? Shoot down airplanes
with an EMP type pulse?

Hmmmm.....

I was proposing to my good neighbor that I need to design a 2-4kw 23khz
directional sound system. Then when the bad neighbors pack of sled dogs get
to barking and fighting, we hit the leader with a blast. He does a backflip
from the pressure wave. May change the pack to the better.
