Abstract

The spatial correlation has previously been investigated for tonal and narrow-band sound fields. This letter presents an experimental investigation of the spatial correlation coefficients in a reverberation chamber driven by broadband signals. The main objective is to verify recent theoretical results for broadband spatial correlation in diffuse sound fields. Experimental results show good agreement with theoretical predictions when the frequency band of the sound field is entirely above the Schroeder frequency.
