Range

In statistics, range refers to the difference between the highest and lowest values in a dataset.

Place Theory

A hearing theory that suggests different areas of the cochlea are activated by different frequencies of sound, enabling us to distinguish pitches.

Basilar Membrane

A membrane in the cochlea of the inner ear that plays a key role in the sense of hearing by vibrating in response to sound and facilitating auditory processing.

Lower Frequency

Refers to sounds or waves that have a lower rate of vibration, and thus a deeper pitch or longer wavelength.
