Abstract

The principles of shading, electrical tapering and beam-steering of arrayed transducers are now more accessible and economical through application of Digital Signal Processing (DSP) for tapering, delays, and equalization. The authors describe how DSP techniques were applied in a very brief development period to produce a loudspeaker of modest dimensions and reasonable cost incorporating transducers, processing, and amplification electronics within one enclosure, and a PC-based GUI for site adjustment of speaker parameters.
