Definitions:

Electromagnetic Spectrum

The range of all types of electromagnetic radiation, which includes, among others, radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Low Frequencies

Refers to sounds or signals that have a relatively small number of cycles or oscillations per second; in audio, it typically describes bass sounds.

Basilar Membrane

The basilar membrane is a key structure in the cochlea of the inner ear, playing a crucial role in the process of auditory transduction by vibrating in response to sound and facilitating hearing.

Place Theory

A theory explaining how the inner ear registers the frequency of sounds, based on the location along the cochlea’s basilar membrane that sound waves peak.
