model of the cochlea

Hello list,

I am interested in obtaining a source program (or any ideas) for determining the 175 outputs of a transmission line model of the cochlea as represented in:

    	An integrable model for the basilar membrane
	M.R. Schroeder
	JASA 1973 53(2) 429-434

	A Dynamical Theory of the Cochlea
	L.C. Peterson; B.P. Bogert
	JASA 1950 22(3) 369-381

Determination of the effects of Dissipation in the cochlea Partition by Means of a Network Representing the Basilar Membrane
B.P. Bogert
JASA 1951 23(2) 151-154

The present plan is to use a differential equation routine such as RKG to obtain outputs at very small time increments along the entire 175 or more sections. Although certainly not in real time this will be the section between the front end (encoding each source position from HRTF like data) and the processing to required to simulate the 3-D positions in the CNS, and then follow this up by determining the actual signal originating ONLY from a particular 3-D position in space. This will complete the total model. At present the DE section is simulated with "representative" outputs.

Any ideas or suggestion on the above will be very much appreciated.
