Sabine's Formula
Sabine’s Formula estimates how long it takes for a room to become acoustically "dead" or quiet after a sound stops. It relates the reverberation time (RT), which is how long sound lasts in a room, to the room's volume and how much sound-absorbing material it contains. Essentially, the more sound-absorbing surfaces and the larger the room, the quicker the sound fades. The formula is RT = 0.161 × (Volume) / (Total Absorption), where the total absorption considers all surfaces' material and area. This helps architects design spaces with appropriate acoustics for speech, music, or quiet.
