Objections against the traveling wave hypothesis Objections against the cochlear amplifier hypothesis Objections against the existing bone conduction signal transfer hypothesis Objections against the existing description of inner ear hydrodynamic behavior The new hypothesis Middle ear functioning Relation between sound stimulus and electrical output in the cochlea Bone conduction The hydrodynamic behavior in the cochlea Von Békésy's traveling wave versus the Bernoulli effect Transfer of sound signals in the cochlea and the Bernoulli effect Methods and experiments for verification Stimulating the cochlea with composed frequency complexes Pitch perception in incomplete harmonic sound complexes Residual pitch perception in enharmonic tone series Addition of harmonics and their influence on beat phenomena Modifying a beat frequency by adding a low frequency stimulus Schouten's explanation for the strike note of bells must be revisited again Is pitch shift in an enharmonic tone complex with equidistant frequencies an illusion? Infrasound can be heard according to the squaring principle The role of DC signals in the organ of Corti and the cochlear amplifier The organ of Corti as a highly selective frequency analyzer Resonance phenomena in the basilar membrane Basilar membrane resonance phenomena instead of travelling waves Verification of calculations of residual pitch and beat phenomena The successive experiments The residual pitch and beat phenomena to be heard in practice Experiments
