Definitions:

Absolute Threshold

The minimum stimulus intensity required to be perceived by the senses, such as the softest sound a person can hear.

Basilar Membrane

A critical structure within the cochlea of the inner ear that plays a key role in sound perception by vibrating in response to sound waves.

Frequencies

The rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves) or in an electromagnetic field (as in radio waves and light).

Place Theory

A theory in hearing that suggests different areas of the basilar membrane respond to different frequencies, helping to identify the pitch of sounds.
