Reverberation chamber is a kind of laboratory for sound spread stimulation. The surrounding material of reverberation chambers must be thick, smooth with low sound-absorbing coefficient, so as to ensure most space of the room meet requirements of spreading sound field.

The center frequency can decide volume of a reverberation chamber. It is normally a cuboid with a hemisphere, cylindrical or other protruded inside stricter to maximize its spreading ability. Moreover, we use materials with low absorbing coefficient, such as tiles, marbles, terrazzo to control absorbing coefficient at or lower than 0.06.
