The reverberation chamber is used to measure absorption coefficients of materials used in buildings throughout the world.
When designing a room, such as a concert hall, it is important that the reverberation time of the space is correct so that speech is intelligible, and music sounds good. You are probably familiar with spaces such as railway stations which are too reverberant – they have too little absorption which makes it difficult to communicate. Knowing the absorption of architectural materials is vital when designing a room with good acoustics.
Acoustic diffusers are used to treat room acoustic defects, but there has long been concerns about the amount of sound absorption that Schroeder diffusers provide. Measurements in the reverberation chamber were used to quantify and ultimately explain the cause of the absorption, and hence enable diffusers with low absorption to be made.
