Based on the values chosen by van Netten and Duifhuis (1983), Duifhuis et al. (1986), and van Hengel (1996) for the human cochlea.

The parameters describing the place-frequency distribution of the cochlea were chosen to agree with the experimental data of Greenwood (1961).

A proportionality between C_p and M_s was maintained to account for tapering in the cochlea, leading to the parameters indicated by footnote c. Zweig (1991); Shera and Zweig (1991).
