Based on the assumptions that indoor acoustic field spread fully and decayed equally, Sabin proposed that the reverberation time is proportion to room's volume, inverse proportion to the volume of sound absorption in the room.

The original method to confirm reverberation time in designs is to use computational formula W. C. Sabin put forward in early century.

最初在设计中确定混响时间的方法是利用W·C·赛宾在本世纪初提出的计算公式。
