Room acoustics measures provide information about how sound behaves inside
a room; how the sound is distributed and the influence of size, shape, surface
materials, etc. Many of the measures are related to the way we perceive and
assess the sound as listeners, as performers in the room, or as recording or
SR engineers. In this chapter some basic room acoustics parameters and the
related measures are briefly described.
