Spatial Bandwidth of Diffuse Radiation in Distributed-Mode Loudspeakers

Authors: Hawksford, Malcolm J.; Harris, Neil

AES Convention 111 · Paper 5412 · November 2001

Abstract

The degree to which radiation from a loudspeaker is diffuse may be quantified by a spatial correlation function normalised to the on-axis response. This is true for any loudspeaker type, including the distributed-mode loudspeaker (DML). However, because of the variation in material damping and design-related constraints, correlation commonly varies both with frequency and direction. A modified function, the offset spatial bandwidth of correlation function, is introduced as a means of describing diffuse performance and quntifying its variation over the radiation field.
