------=_Part_1496_15885261.1281096540468 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Dear colleagues, =20 My new book "Introduction to Cochlear Waves" is now available via the publi= sher's website, www.vdf.ethz.ch. =20 The first parts of the book are devoted to a =E2=80=9Cpassive=E2=80=9D coch= lea, i.e., to cases in which the mechanical energy generated by =E2=80=9Cac= tive=E2=80=9D outer hair cells is absent or negligibly small. Passive human= cochleae were studied, e.g., in the post-mortem experiments of von B=C3=A9= k=C3=A9sy, who found that tones generate, in the cochlear channel, travelli= ng hydrodynamic surface waves which are similar to waves propagating on the= ocean. In spite of the fact that the travelling-wave energy starts to be t= ransformed into frictional heat at the cochlear base already, the velocity = amplitude of the basilar-membrane oscillation increases with increasing dis= tance from base. At some place, namely at the =E2=80=9Cpassive peak=E2=80= =9D, that increase stops, and at greater distance from base the amplitude q= uickly drops to small values. At high [low] tone frequency, the distance fr= om base of the passive peak is short [long].=20 Additional topics treated in this book: the outer hair cells and the =E2=80= =9Cactive=E2=80=9D response peak generated by them; evanescent cochlear wav= es; high-frequency plateaux; cochlear maps; certain forms of tinnitus; oto-= acoustic emissions; frequency glides. The readers are expected to know high-school biology, physics, and mathemat= ics. Exercises and their solutions are included at the end of most chapters= . Reinhart Frosch, Dr. phil. nat., r.
