Diffusion, in architectural acoustics, is the spreading of sound energy evenly in a given environment. A perfectly diffusive sound space is one in which the reverberation time is the same at any listening position. Most interior spaces are non-diffusive; the reverberation time is considerably different around the room.
The compositional practice of acousmatic music features acousmatic sound, sound which is heard but not seen, as a central musical aspect.
