概要 The physically control a high-precision or wide-area sound field requires a highly complex reproduction system owing to the large number of loudspeakers required. Previously, we developed a 256-ch planar loudspeaker system with simple electrical circuits by using high-speed 1-bit signals. In this study, we proposed a 320-ch three-dimensional loudspeaker system by extending the previous developed system. Introducing ARM/FPGA SoC has made it possible to control a large number of audio signals via Linux OS. To investigate a reproducible sound field using the proposed system, a preliminary experiment was conducted by simulation of sound ?eld reproduction with Wave Field Synthesis and Near-Field Compensated Higher Order Ambisonics.
