A theoretical study explores the way in which sound equalization of the magnitude response in enclosed spaces can be achieved by controlling source locations. The optimization aims to create the desired sound pressure corresponding to that of a plane wave. Sources are placed so that they couple to the beneficial room modes while avoiding those modes that would degrade performance. Simulation results for a rectangular room and an automobile cavity show the benefits: reduced error and increased spatial robustness.
