Building Acoustics Laboratory Sound Absorption in a Reverberation Room EN ISO 354 / ASTM C423

In the reverberation room we test how much sound a test object can absorb. The sound absorption capacity describes the ratio of sound-absorbing properties to the reflecting properties of the test objects. Indoor building products can reduce noise due to their sound-absorbing properties.
