Reverberation time in Receiving Room

Place your microphone(s) in the receiving room. Place the loudspeaker in the receiving room. You may want to use an extra loudspeaker for this measurement so you don’t have to carry the loudspeaker from the sending room.

The reverberation time is to be measured according to ISO 345 where a loudspeaker is to be used as sound source. But another method that is used by some consultants and supported by WinMLS is to use a starting pistol or balloon (the measurement can be done without using any loudspeaker).

 

How to do this for the two possible methods is explained below.
