Abstract

An acoustic signal or an acoustic disturbance consists of pressure oscillations traveling in an elastic medium. The variation of pressure can either be triggered by a vibrating surface (for example, diaphragm of a speaker) or by a turbulent fluid flow. In a broad sense, a sound wave is any disturbance that propagates in an elastic medium, which may be either a gas, a liquid, or a solid.
