Measurement system for the determination
of sound absorption in reverberation rooms
In the reverberation room, reverberation time measurements can be used to determine the sound absorption coefficient of planar objects and the equivalent sound absorption area of single objects for diffuse sound incidence. In large reverberation rooms, measurements are made according to ISO 354 (V ≥ 150 m³) or ASTM C423 (V ≥ 150 m³) and in small rooms according to SAE J2883 (V ≥ 25 m³) or special factory standards such as PR 353.
The software m|abshall enables the measurement and evaluation of sound absorption according to all known test specifications.
