Default I don't even know what to call this-

Ok, put on the headphones and play a 1kHz tone at a medium level. Now, tap your head with your finger. Try to get some bone conduction. What do you hear? Does this have any impact on audio reproduction (no pun intended) as low bass notes combine with the highs?

Christer- maybe that's correct! I hear the sine significantly modulated by the tapping. Maybe I need to apply damping material

Conrad,

One problem is that you are tapping your own head. There is mechanical movement of the body involved. I can agree that gives some type of modulation. It would be better to have somebody else tap the head.

There are also actuators for bone conduction that are used in audiology and sound therapy. That would allow you to play with these things, if using uncorrelated signals for air conduction and bone conduction, which is usually not supposed to happen in nature.

Gives a whole new meaning to the term head banger.
On the other hand, head tossing hardrockers invented digital reverb.

It could be interesting, perhaps, to try tapping the head of a musician while he/she is playing, to see if it affects the playing.
