A short review is given of the acoustics of the reverberation chamber. Earlier work by Sabine, Bolt, and Cook is discussed, and the effects of moving the position of the source, the receiver, and a reflecting vane are considered. The statistical properties of reverberant sound fields without time‐varying elements are reviewed, and the space‐variances obtained by averaging at discrete points and along a continuous traverse are compared. The case of the reverberant sound field produced by a band of noise is then taken up, and finally some areas needing further study are mentioned. These include the accurate measurement of the power output of a pure‐tone source, and the theory and practice of moving reflectors.
