Definitions:

Place Theory

A theory in hearing that suggests different areas of the cochlea are activated by different frequencies of sound, contributing to our perception of pitch.

Eardrum

A thin membrane that separates the outer ear from the middle ear and vibrates in response to sound waves.

Oval Window

A membrane-covered opening that leads from the middle ear to the inner ear, transmitting vibrations from the eardrum to the cochlea.

Cochlea

A spiral-shaped, fluid-filled inner ear structure that is essential for hearing; it translates sound vibrations into nerve impulses.
