Acoustics program for calculating acoustic properties of rooms. ... The time taken for sound to die away is known as the reverberation time and is dependent on the total room absorption and the room volume. There are 2 formulae used. Sabines formula for rooms up to 1000 cu.m. and the Norris-Eyring formula for larger spaces.

Calculating Reverberation Time ... Optimum reverberation time is a compromise between clarity (requiring short reverberation time), sound intensity (requiring a high reverberant level), and liveness (requiring a long reverberation time).

Hard surfaces reflect sounds back. Open windows let them escape. From a listener's perspective, with acute and spatially accurate hearing, the reverberation: the sound that comes back to you - is a key means of understanding the nature and properties of inhabited space - a three dimensional aural map.
