Add linear distance in the cochlea for freq and wavelength

"Greenwood proposed the following equation for frequency along the OC: F = A · (10ax – k), where F is frequency, x is the position on the basilar membrane; coefficients for human cochle- ae: A = 165.4, a = 2.1 (if x is expressed in proportion of the total basilar membrane length), k = 0.88 [Greenwood, 1990]."
