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?

I am curious.

I hear a sine and a tapping on my head. What am I supposed to hear?

Maybe your skull has mor IM than mine?

 

[QSerraTico_Tico]

Try 130dB+ at rock concert!

 

[Conrad Hoffman]

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

 

[Christer]

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.

QonTico,
looks like beach weather overhere, i like to tap my head when i'm looking at lush bikini girls, minus the bikini.

 

[Christer]

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.

I hear knok, knok, anyone there?!

What happens if you try this without headphones?

Remember that the headphones are occluding your ear canals and not allowing the low frequecies to leak out.

Same reason your voice sounds strange when you are wearing earplugs.

I prefer a perforated salad colander for better ventilation. I do have to try this without headphones.
