Consonance, Hearing Science, Psychoacoustics, Cochlea

This monograph is focussed onto the sensory consonance of two simultaneous complex tones. Part One describes psycho-acoustic consonance experiments undertaken by the author and by several earlier researchers. Some of these experiments were informal one-man studies, while others involved fairly large groups of subjects and subsequent statistical analysis. Part Two contains selected chapters of cochlear mechanics.

Cochlear Mechanics, Cochlea, Hearing Science

The first parts of the present text are devoted to a "passive" cochlea, i.e., to cases in which the mechanical energy generated by "active" outer hair cells is absent or negligibly small. Passive human cochleae were studied, e.g., in the post-mortem experiments of von Békésy, who found that tones generate, in the cochlear channel, travelling hydrodynamic surface waves which are similar to waves propagating on the ocean.

In this monograph, based on a course that the author taught at ETH, it is shown that a spectacular formal simplification of the equations representing the basic laws of classical physics (e.g. the Maxwell equations of the electromagnetic field) is achieved if the accustomed three-vectors are replaced by four-tensors.
