fingers in ears-filter?
 
i had my fingers in my ears to isolate ,to focus on my walls wobbling to see where it was worst..



if u put ur fingers slowly in and out of ur ear,u get a filter effect.
what would the frequency reponse of this effect be?

simple low 1st order low pass with varying frequency?
if your ear is a horn,what is your finger in it,some sort of restriction?

arent ears interesting!

Not an answer to your question, but I read once that an ear manages a volume compression effect by pulling the eardrum tighter during high sound levels. This would alter it's resonant frequency and there it's frequency response with volume, as is well known.

Some of them early pioneer communities must have been just a bit too inter-related to each other. After all, didn't Daniel Boone have a wild front-ear? :clown:

I have observed this effect too. I find sometimes when I'm in a cathedral listening to music, I cup my hands around my ears, and get a neat effect.

Lately I have been irritated at this though, because I realize that it sounds like a very badly designed horn.

You are getting confused with Captain James T. Kirk. He had 3 ears - a left ear, a right ear and a final frontier :)
