Product Usage
The indoor of the reverberation room is all covered with
reflecting materials. The sound-absorbing ratio of sound
generated indoors almost reaches 0 from all parts of the
indoor to maintain a diffuse field with uniform sound pressure
distribution and maintain a fixed reverberation time.
Product Features
To measure PWL, sound-absorbing ratio, transmission loss,
silencer insertion loss by maximally reflecting a sound source
generated indoors from all parts of the indoor.
Since the indoor sound pressure distribution is almost
uniform, the examination of a sound source is impossible.
