A source can be characterized by the sound pressure level it produces at a given distance. This level depends on the nature of the source, as well as propagation conditions (boundary conditions imposed by the walls of a room, for example).
It seems more convenient to characterize this source by an energy quantity: the acoustic power supplied by the source.
In the general case of a complex sound source,...
