Pitch perception is explained by two competing physiological models of the inner ear
Evidence
The temporal theory of pitch perception relies on the timing of neural firings generated in the organ of Corti (see Figure 2.3), which occur in response to vibrations of the basilar membrane. The place theory is based on the fact that the basilar membrane is stimulated at different places along its length according to the frequency components in the input sound. The key to the temporal theory is the detailed nature of the actual waveform exciting the different places along the length of the basilar membrane. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 892
