Abstract

A new method of measuring spatial correlation functions in reverberant sound fields is presented. It is shown that 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 used to verify theoretical predictions of the spatial correlation between various components of the particle velocity in a diffuse sound field.
