Spatial Distribution of Distortion and Spectrally-shaped Quantization Noise in Digital Micro-array Loudspeakers
A concept for a digital loudspeaker array is studied composed of clusters of micro-radiating elements that form individual digital-to-acoustic converters. In this scheme a large-scale array is composed of subgroups of micro clusters. To accommodate the finite resolution of each cluster, noise shaping is proposed and parallels are drawn with the processes used in digital-to-analogue converters. Various elemental array geometries for each micro cluster are investigated by mapping transduction output into 3-D space to reveal the spatial distribution of both noise and distortion that result from non-coincident and quantized digital-to-acoustic elements.
