Theories of Pitch Perception
Theory
Description
Place theory
Different pitches of sound activate specific regions of the basilar membrane more than
others. Pitch perception occurs when the brain notices which portions of the basilar
membrane are being most excited by incoming sound waves.
Frequency theory
Volley theory
Duplicity theory
The hair cells of the basilar membrane fire action potentials at a rate equal to the
frequency of the incoming sound wave. The brain determines pitch by noticing the rate
at which the hair cells are firing. This theory only explains perception of pitches up to
1,000 Hz, the maximum firing rate of a hair cell.
Similar to frequency theory, this theory states that groups of hair cells fire as teams to
give us the perception of pitches over 1,000 Hz. For example, three hair cells each firing
at 1,000 Hz together yield the perception of a 3,000-Hz tone.
This theory states that a combination of frequency and place information is used in pitch
perception. Exactly how these sources of information are integrated in the brain is still
being investigated.
