Sound Energy

Last Updated: June 29, 2018

Definition - What does Sound Energy mean?

Sound energy is the physical vibration waves that travel through the air to reach the ears signaling the brain to interpret incoming sound(s). Sound energy derives from an external source like playing a drum, for example, triggering vibrations to carry through the ambient air to engage listeners. Sound energy waves comprise of two properties called compression and rarefaction, giving it a distinct formation. Sound energy contracts (compression) and expands (rarefaction) through conductive mediums like air, water, or steel. The rate at which sound energy travels depends on its frequency range, also called pitch, and its amplitude, the degree of loudness.

WorkplaceTesting explains Sound Energy

Sound energy enables people to hear a broad variety of sounds that prompts different biological and psychological reactions.Workplace environments can be relatively loud, especially in industrial and manufacturing settings. For this reason, there is an important distinction to note between sound energy and noise. Sound energy occurs naturally when a vibrating object disturbs the surrounding medium (i.e. air or water) by propelling the energy forward in a continuous wave. However, noise is considered an unpleasant byproduct to any sound made from an object based on sound pressure level, or loudness factors.

Many industries consist of noisy environments, making hearing a health and safety concern issue. However, there are soluble measures available to control noise levels like wearing earmuffs or earplugs. The human ear can detect sound energy from a vibrating source based on fluctuating pitch (frequency) ranges.
