| 摘 要： | 文章对穿孔板背面紧贴吸声薄层时的声学特性进行了理论分析与计算。并与实验结果作出比较。理论与实验者表明，当穿孔板背后紧贴吸声薄层后，由于穿孔末端增加的附加声阻，将会显著提高穿孔板的吸声效果。同时拓宽吸声频率带宽度。

| Abstract: | Theoretical analysis of acoustic properties of perforated panel closely pasted with an absorptive thin layer is described in this paper.The calculation and measurement indicate that the acoustic resistance produced by end correction of hole will make dominant contribution to sound absorption of perforated panel structure and expand the bandwidth of sound absorption. |

| Keywords: | perforated panel end correction absorptive thin layer |
