The reverberation time is a measure of how fast the sound dies away in a given room.

The size of the room and the choice of materials determine the reverberation time.

Once we know the sound absorption coefficient of a material and how much of it there is in a room, we can calculate the total absorption in the room. The unit of measurement is the metric sabin (m2 sabin).

Once we know the size of the room and the total absorption, using Sabine’s equation we can calculate the reverberation time, even before the room is built.
