Definitions:

Basilar Membranes

A key structural element within the cochlea of the inner ear, it plays a crucial role in the mechanical to neural transduction of sound.

Frequency Theory

A theory in the field of psychology, explaining how the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, allowing us to sense its pitch.

Place Theory

The theory of hearing that holds that each individual pitch a person hears is determined by the particular location along the basilar membrane of the cochlea that vibrates the most.

Volley Principle

A theory in hearing that suggests groups of auditory neurons respond to a sound by firing action potentials slightly out of phase with each other, allowing for the perception of sounds up to 5000 Hz.
