3. Room reverberation time or duration
3.1 Room absorption according to Sabine's assumptions
The integral over the entire surface of the room is, in practice, difficult to assess for rooms with inhomogeneous walls.
However, Sabine's formula allows us to estimate the average...

Room quality assessment criteria
As early as 1900, Sabine implicitly introduced the first criterion of room quality, based on the estimated reverberation time. Today, most authors agree that the acoustic quality of a room can be determined from a minimum of four or five criteria.
Among the most frequently cited are EDT [Early Decay Time: reverberation time calculated over the 0 to – 10 dB interval of the impulse...
