Text: [ACOUSTICS] Time required for average sound pressure level in a room to decrease 60 db after a steady state source stops generating sound. Can be estimated from: T = 0.049(V/A) or T = 0.161(Vm/Am) where: T = reverberation time in seconds V = room volume, cubic feet A = total room absorption, Sabins Vm = room volume, cubic meters Am = total room absorption, metric Sabins
