Laboratory reverberation rooms as described in ISO 3741 are particularly suitable when performing precision-grade tests on comparatively small machines where the sound emitted is predominantly steady in character.
Multy has been tested with regards to sound absorption using the random incidence method in a reverberant room as provided for by ISO 354, obtaining “sound absorption class A” in compliance with UNI EN ISO 11654.

Measurement of sound absorption in the reverberation chamber.
To construct a reverberation chamber, a chamber (1) provided with reflecting walls (27) is intended to contain an antenna (21) and a field stirrer (26) which are placed opposite an object (12) to be tested.
Measurement of sound absorption in the reverberation chamber.
This makes the room reverberant, and therefore, noisy.
