THREE-DIMENSIONAL SOUND FIELD REPRODUCTION AND RECORDING SYSTEMS BASED ON BOUNDARY SURFACE CONTROL PRINCIPLE

Based on the boundary surface control (BSC) principle, a new recording/reproduction system is developed to realize high fidelity three-dimensional sound field reproduction. Theoretically, using this new system, perfect sound field reproduction can be achieved in any acoustic environment. Sound recording / reproduction systems based on the BSC principle require many loudspeakers and microphones. In the new system, the microphone array system that is used to record the 3D sound field consists of 70 microphones, and the loudspeaker system to reproduce the recorded 3D sound field consists of 62 full-range units and eight sub-woofer units. This paper describes the composition of the new recording/ reproduction system and evaluates its ability by means of sound localization tests with nine subjects. Results of experiments show that a clear sound image in the horizontal plane is reconstructed using the proposed system.
