In models of the basal region of the cochlea, the basilar-
membrane stiffness S is often assumed to depend on the
longitudinal coordinate x as follows:
S = S_0 * e^(-x/d) ,
where d is about 3 mm. Yesterday I found that absence
of significant reflections is predicted even for low
frequencies if a different function is used instead:
S = S_0 * [1 - x/(4d)]^4 .
I have written a text-file of about 1.5 pages giving details.
Please write if you want to receive that file.
With many thanks, sincerely,
