Calculation formula of reverberation time

Calculation formula of reverberation time

1. Formula used for general approximate calculation and sound absorption coefficient measurement in reverberation chamber:  line array speaker

2. Formula used for measuring sound absorption coefficient in concert hall, auditorium, gymnasium, theater and other large space occasions.

3. Formula used for measuring sound absorption coefficient in small space situations such as audition room, AV audiovisual room and studio.

4, the following is summed up in the room for the acoustic processing of the calculation of the calculation of the formula to sum up, if there are inappropriate, look at the high criticism to be appreciated!!!


Remarks: V = room volume S = inner surface area A = sound absorption T = reverberation time.

A = absorption coefficient 4m = air sound absorption coefficient = average sound absorption coefficient.
