Diffuse signal processing and acoustic source characterization forapplications in synthetic loudspeaker arrays

摘要

Active diffuse loudspeaker arrays can be implemented by incorporating a distribution of small radiating elementseach characterized by processes that embed a unique diffuse impulse response. The properties of synthetic diffuseimpulses are investigated both individually and collectively and algorithmic generation techniques presented. Thediffuse properties of such synthetic arrays are confirmed both by polar response descriptors and spatial correlationtechniques.
