摘　　要：通过对邦达吸声板混响室吸声系数的测量，分析了材料穿孔、不同空腔深度、安装方式对吸声特性的影响及其应用。并与目前常用的强吸声材料吸声特性进行了比较。Having measured the sound absorption coefficient of BOMDER soundabsorber in reverberation room, this article analyzed the influences that the materialbeing perforated or not, different depth of space from the wall, different arrangementtype and its application. The article also compared the absorber's sound absorptioncharacteristics with some usually high sound absorption material.
