Definitions:

Place Theory

A proposal about pitch perception stating that regions of the basilar membrane respond to particular sound frequencies, and the nervous system interprets the excitation from different basilar regions as different pitches.

Oval Window

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

Cochlea

A spiral-shaped, fluid-filled inner ear structure that is essential for converting sound waves into electrical signals that can be interpreted by the brain as sound.

Waves

are disturbances or variations that travel through a medium, such as air, water, or vacuum, transferring energy from one point to another without permanent displacement of the particles of the medium.
