Definitions:

Amplitude

The greatest distance of a swing or fluctuation, measured from the point of balance.

Place Theory of Pitch

A theory that suggests the perception of pitch relates to the location of maximum vibration on the basilar membrane inside the cochlea.

Basilar Membrane

A structural element within the cochlea of the inner ear that plays a critical role in sound perception by vibrating in response to sound waves, thus contributing to the mechanical processes that convert sound into neural signals.

Oval Window

A membrane-covered opening that leads from the middle ear to the inner ear, playing a crucial role in the process of hearing.
