Simulated Diffuse Field Measurements

Authors: Struck, Christopher J.

AES Convention 107 · Paper 4990 · September 1999

Abstract

The asymmetric polar response of an in-situ microphone system requires calculation of the Directivity Index (DI) from the random incidence response. A technique is presented that enables diffuse field measurements to be performed, without a reverb chamber, in a moderately sized, untreated room over a reasonably wide bandwidth. Applications of this technique are given and results for different devices are shown.
