Dear colleagues,

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,

Reinhart Frosch.
