Abstract

Many near-field acoustical holography (NAH) algorithms, including statistically optimized near-field acoustical holography (SONAH), have been well developed and verified via computer simulations. In this paper, design, implementation, and performance of a DSP-based real-time system for sound field visualization using SONAH algorithm is discussed. The prototype system consists of a 24-element microphone array connected to a TMS320C6678 DSP daughterboard hosted by a PC, validated by both computer simulation and experiments performed in an anechoic chamber, visualizing the sound field of a reconstruction plane in front of two speakers. The system has prospective practical applicability in industry applications.
