Power, Acoustic
the energy carried by a sound wave through a particular surface per unit time; it is measured in watts. A distinction is made between the instantaneous value of acoustic power and the average over the period of an oscillation or a prolonged time interval. Of greatest interest is the average acoustic power per unit area, which is called the sound intensity. Want to thank TFD for its existence?
