Multi-Channel Sound Synthesis System in Open Area. A Case Study with the Use of~FEM

Abstract

This paper presents a new model of the multi-channel sound synthesis system. The research objective was to design and construct a sixteen-channel sound control system located in an open area with dimensions of 23.48 m × 17.48 m. The main goal of the system operation is to provide, for the controlled acoustic eld, the uniformity of the parameters distribution while minimizing the sound pressure level in the protected area. The modeling and simulation researches have been performed using the Finite Element Method (FEM). The results of the analysis include distributions of the sound pressure levels and phase angle for the selected frequencies. The paper presents results of sensitivity studies and optimization for dierent variants of the sound synthesis system.
