Sound power or acoustic power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit time.<ref name=clinical>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref> The SI unit of sound power is the watt (W).<ref name=clinical/> It is the power of the sound force on a surface of the medium of propagation of the sound wave. For a sound source, unlike sound pressure, sound power is neither room-dependent nor distance-dependent. Sound pressure is a measurement at a point in space near the source, while the sound power of a source is the total power emitted by that source in all directions. Sound power passing through an area is sometimes called sound flux or acoustic flux through that area.
