概要

• 論文の詳細を見る

• The details of the new reverberation chamber are given. It has a volume of 513m^3 and is surrounded by nonparallel walls. The results of model room experiments previously reported have been used to determine the shape and volume of this chamber. At 500 cps., the reverberation time of empty chamber was 22 seconds. The position of the microphone and the sound absorbing material did not affect the reverberation time of this chamber. This fact would show that the sound field of this chamber would fulfill the requisite for the diffuse sound field which is the premise of the reverberation chamber method.
