Abstract
In order to analyze the complex influential factors on the sound field of audio directional systems, investigate the mechanism of the associated basic acoustic theories, and study how the system performance vary with the change of parameters. Then integrate these theories and analyze their combined effects on the sound field. The accurate numerical model of the sound field including multi-parameters is built, and the sound field distribution and its mechanism are simulated by MATLAB software. The results of comparative analysis presented in this work will facilitate the design of audio directional system.
