Do materials alter frequencies and speed?

What is the resonant frequency of earwax?
I'm going to connect my turntable to my cochlear imlants and skip the rest of the system.

What is the resonant frequency of earwax

:>)Dunno, but there's a pole s/where around 15kHz if I remember correctly. With your "direct-line" method, maybe we can dispense with the riaa correction altogether...

When the Audioligist fitted my wife for hearing aids, the first thing she did was to measure the acoustic characteristics of the ear canal. This was factored in to the algorithm programmed into the devices.

I posted that question hoping to draw some of the snipers in the thread. In reality the acoustic characteristics of the canal vary widely and the artifacts of residual cerumen do alter the mechanical feed to the tympanic membranes. The membrane and 3 bones(incus,stapes and malleus) send the vibrations to the hair cells of the cochlea. At this point the mechanical energy is converted to electrical impulses that the cochlear nerve supplies to the brain(Broca's area).
What arrives at the brain is influenced at each of these junctures. Do clean ears optimize sound... I think yes! Should your audio system be tuned to compensate for inconsistencies in tympanic output(confirmed by audiogram)...I don't know. Would any of this standardize the listening experience? Tweaks for rooms, cables, electronics and speakers are de riguer. Should we tweak the organic end of the system as well?
Next week, sound modeling in the middle and inner ear and do the Eustachian Tubes control porting in your head.

Alright already! Let's let this one die!
