It explains how we hear high-pitched sounds very well but doesn’t explain how we hear low pitched ones very well
|
|
It proves that the human ear has more parts than we think it does
|
|
It proves that sound can travel faster/as fast as the speed of light to reach our ear but doesn’t technically prove how fast the sound is going

None of the above

Detailed explanation-1: -The biggest problem of the place theory is that it fails to identify the pitch of a stimulus with missing fundamental. According to Helmholtz’s theory, it is impossible to perceive a pitch when there is no spectral peak at the position along the basilar membrane which corresponds to the frequency of the pitch.
Detailed explanation-2: -In all cases, neural firing patterns in time determine the perception of pitch. The combination known as the place–volley theory uses both mechanisms in combination, primarily coding low pitches by temporal pattern and high pitches by rate–place patterns.
Detailed explanation-3: -According to the frequency theory of hearing, the frequency of the auditory nerve’s impulses corresponds to the frequency of a tone, which allows us to detect its pitch. Sounds come into the ear as acoustical signals and are later transformed into nerve impulses by the cochlea.
Detailed explanation-4: -The place theory of hearing suggests that we hear different pitches because different areas of the cochlea respond to higher and lower pitches.
