A MULTI-MICROPROCESSOR CONTROLLED DYNAMICALLY RECONFIGURABLE PHASED LOUDSPEAKER ARRAY FOR SOUND REINFORCEMENT APPLICATIONS
Abstract
A mathematical model is derived for simulating the directivity pattern of arbitrarily positioned loudspeakers possessing defined dispersion, amplitude, and phase delay characteristics. A practical implementation is then presented which incorporates the gain and phase delay control mechanisms suggested by the mathematical model. Programming considerations relevant to effective simulation of the mathematical model are discussed next, followed by a series of case studies. The case studies presented range from simple cases for which there are known analytic solutions to relatively complicated multi-array configurations for which no analytic solutions are known. Investigation of the various control mechanisms also includes a cursory study of dispersion tracking simulation using both spectral and phase delay vector massaging. A discussion of possibilities for future research conclude this presentation.
