IEVref: 801-31-10 ID: Language: en Status: Standard Term: Sabine absorption Synonym1: Synonym2: Synonym3: Symbol: Definition: sound absorption defined by the Sabine reverberation-time equation NOTE 1 – The Sabine reverberation-time equation is: $T=\frac{\left(24\text{\hspace{0.17em}}\text{ln}\text{\hspace{0.17em}}\text{10}\right)V}{cA}=\frac{55,3}{cA}\text{\hspace{0.17em}}V$ where: 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. NOTE 2 – The unit of Sabine absorption is the decibel metre-squared, sometimes known as the metric sabin.
