Dear colleagues, While working on a planned monograph on cochlear origins of musical ("sensory") consonance I got interested in the reflections of "passive" waves in the basal turn of the cochlea (or, rather, in the absence of such reflections in a smooth cochlea). Reflections of "long" waves (wavelength much greater than 2 pi times channel height) are negligible if the spatial rate of change of the local wavelength lambda fulfils the following inequality: d lambda / dx << 2 pi . (1) [The local wavelength is 2 pi / k , where k is the local wave number.] A formula equivalent to (1) [see above] is Eq. (4.3.7) in E. de Boers chapter of the book "The Cochlea" [P. Dallos et al., eds., Springer, New York, 1996]. A detailed derivation of that formula is not given, however. I have just succeeded to work out such a derivation, I think; nevertheless, I would be grateful for information on helpful not-too-high-level books or papers. Reinhart Frosch.
