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?

Later,
