Abstract
A new method of measuring spatial correlation functions in
reverberation rooms is presented. It is shown that the coherence
functions determined with appropriate spectral resolution contain
the same information as the corresponding correlation functions,
and that measuring such coherence functions is a far more
efficient way of obtaining this information. The technique is then
used to verify theoretical predictions of the spatial correlation
between various components of the particle velocity in a diffuse
sound field. Other possible applications of the technique are
discussed and illustrated with experimental results obtained in an
ordinary room.
