Optimizing the Controls of Homogeneous Loudspeaker Arrays

Authors: Sandler, Mark; Terrell, Michael

AES Convention 129 · Paper 8159 · November 2010

Abstract

An optimisation technique is demonstrated which can be used to control the frequency response at multiple receiver locations to a homogenous loudspeaker array. Each loudspeaker element in the array is identical, but can be controlled individually using vertical and horizontal angle, delay, broadband gain, a 7-band parametric equalizer and a 5th order all pass filter. The arrays examined contain eight loudspeakers, and the controls are optimised using a genetic algorithm. This is demonstrated for a 2D case study based on the requirement that the magnitude response at each location is the same.
