Definition: | sound absorption defined by the Sabine reverberation-time equation
NOTE 1 – The Sabine reverberation-time equation is: $T=\frac{\left(24\text{\hspace{0.17em}}\text{ln}\text{\hspace{0.17em}}\text{10}\right)V}{cA}=\frac{\mathrm{55,3}}{cA}\text{\hspace{0.17em}}V$
where: NOTE 2 – The unit of Sabine absorption is the decibel metre-squared, sometimes known as the metric sabin. | ||

*T* is the reverberation time, in seconds

*V* is the volume of the room, in cubic metres

*c* is the speed of sound in the air contained in the room, in metres per second

*A* is the sum of all Sabine absorptions in the room, in decibel metre-squared.
