I know that you get different perceptinns of pitch if headphones are
forward,
centered and behind the ears. No idea why.

For headphones, I'll bet it has a lot to do with the way heads are
constructed, with lots of hard stuff, soft stuff and hollow places.

I noticed that when I scratch my inner forearm, I can hear it in the back
of my head. Bone conduction?

Remember those radios that were designed to hang over your shoulders and
send sound through the back of your neck?

I play a windsynth. I've always wanted a piezo tranducer in the mouthpiece
so I could hear it through my teeth the way sax players do.
