Review of Radio Science: 1999-2002 URSI
Due to its crucial significance in evaluating the result of a test, the relationship
between anechoic and reverberation chamber testing is discussed. Also, the
problems of defining and operating at the lowest usable frequency are treated.

Room Acoustics, Fifth Edition
One is to place seats and/or persons into a reverberation chamber and evaluate
their absorption from the change in reverberation time they cause. This has the
advantage that sound field diffusion, which is a prerequisite for the applicability of

Electromagnetic
Reverberation Chambers
For an ideal reverberation chamber (see section 3.2 of Chapter 3 for the
description of the model of ideal random field in a reverberation chamber), the
statistical behavior tends towards Rayleigh's distribution. Consequently, the fR
probability ...

Measurements using Optic and RF Waves
With regards to the electromagnetic environment, tests in a reverberation
chamber are totally different to tests in an anechoic chamber. The solicitation of
the test object is therefore different and it is particularly important to lay down a
few ...
