The secrets of hearing

The first part presents a brief history of hearing theory and highlights only some of the issues of the still recognized hearing theory of travelling wave by Bekesy. The second part presents a new vision of hearing, in line with current knowledge. It deals with the reception, processing and transmission of auditory information. The most important processes involved in the transformation of the energy of a sound wave take place at the molecular and electron (submolecular) level. Particular attention is paid to the signal path to the receptor and the mechanism of intracellular amplification.
