声源指向性对ODEON音质模拟影响研究

摘要

ODEON generally uses spherical nondirectional source in acoustical simulation. But there are measurements of acoustic parameters using directional sound source. Combined with two different actual cases, this paper explored the influence of source directivity pattern and receiver position on the a-coustic parameters simulation under two different acoustic conditions, and the results were analyzed.%ODEON在音质模拟中一般使用球面无指向性声源,但有一些声学参量在实际测量时使用指向性声源.文中结合两个实际案例研究了在两个不同的室内声学条件下,声源指向性特征以及接收点位置对各声学参量模拟结果的影响,并对结果进行了分析.
