Dear list,

in order to estimate the propagation time of the traveling wave on the
BM for certain frequencies I need to know the propagation speed of the
wave.

In

(at)article{HEI05,
author = {Heijden, Marcel van der},
title = {Cochlear gain control},
journal = {The Journal of the Acoustical Society of America},
volume = 117,
number = 3,
pages = {1223-1233},
month = mar,
year = 2005
}

I found that the propagation speed is frequency dependent.

Are there any more detailed articles, which (hopefully) contain kind of
a 'delay profile'? That is the time it takes for a given frequency to
evoke a stimulus at the 'proper' hair cells. Reference time for the
delay time is the moment at which a stimulus is evoked for the highest
perceptable frequency resp. at the base of the BM.


Best regards,
