Definitions:

Decibels

A unit of measurement used to express the intensity of sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.

Long-term Exposure

Prolonged contact or engagement with a particular substance, environment, or stimulus, which may have lasting effects on health or behavior.

Sound Waves

Sound waves are vibrations that travel through the air or another medium, which can be heard when they reach a person's or animal's ear, characterized by their frequency, wavelength, and amplitude.

Frequency

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).
