Resonance phenomena in the basilar membrane Basilar membrane
resonance phenomena
instead of traveling waves

not a traveling wave but a 'phase wave'

that consists of coherent place dependent phase shifted local reactions to a stimulus that is simultaneously present throughout the basilar membrane

Resonance phenomena in the basilar membrane

And what phenomenon is comparable to this?
The “wave” in the stadium!

And dependent on the quality factor in resonance, strongly coupled to the rate of damping, the moving area becomes smaller, while the maximum deflection becomes larger.

On theoretical grounds it is no mystery that this “wavy movement” of the BM is always running from the round window [base] towards the helicotrema [apex] of the cochlea.

It is a locally bound reaction behavior on a universally existing stimulus.
Using the material specifications this behavior can be calculated in a perfect way.
