Definition: Acoustics is the science and technology that study the generation, spread, and effects of sound.
Acoustics is one of the branches of physics. It is the science that studies the generation, propagation, reception and effects of mechanical waves in media. The medium includes various states (solid, liquid, gas, etc.), and may be an elastic medium or an inelastic medium. Mechanical waves are propagation phenomena of changes in particle motion (including changes in one or more of displacement, velocity, and acceleration). Mechanical waves are sound waves.
