The evanescent liquid sound-pressure wave described in Section 2.2 fulfils the Laplace equation. It is however incompatible with Newton's second law applied to the friction-less passive basilar-membrane (BM) elements of a cochlear box model with x-independent BM stiffness S and BM surface mass density M and with negligible direct mechanical coupling of the BM elements. In the real cochlea, slow traveling surface waves of given frequency are impossible at the without-liquid BM resonance place for that frequency, but are possible at the corresponding with-liquid resonance place, which is more basal by typically 0.24 octave distance.
