摘　　要： FC穿孔板是常用的吸声装饰材料,以高穿孔率的FC板与板后衬贴不同材料和空腔填充玻璃棉,组成6种吸声构造,分别对4种空腔深度进行混响室吸声测量,通过对吸声系数的分析,探讨板后衬贴材料及填充材料FC穿孔板的吸声效果。 FC perforated plate is a commonly used sound-absorbing decorative material. It is characterized in that 6 kinds of sound ahsorption structures are composed of a FC plate with a high perforation rate and a different material and a space filled with glass wool. The 6 kinds of sound absorption structures are respectively used for the measurement of sound absorption in a reverberation room of tire 4 kinds of cavity depth, and through the analysis of the sound absorption coefficient, the paper discusses tire sound ahsorption effect of the back lining material and the filling ,naterial on the FC perforated plate.
