| 摘 要： | 分析不同共振频率的微穿孔板吸声结构并联的结构模型,并计算了其组合吸声系数。理论计算结果与采用SYSNOISE软件,根据GB/T 18696对并联的微穿孔板吸声系数进行仿真实验得到的结果及已有实验数据进行对比。结果表明,该文中并联微穿孔板吸声结构的声阻抗率及组合吸声系数的计算方法是可行的。

| Abstract: | The structure model of parallel microperforated panels(MPP) with different resonance frequencies has been studied in the paper,and the combination absorption coefficient is also calculated.The calculation results of absorption coefficient have been contrast with the experiment results,which come from the existed experiment results and simulation experiments by the SYSNOISE software according to the GB/T 18696.The experiment result indicates that the calculation method of the acoustic impedance ratio and the combination coefficient of the parallel MPP in the paper is credible. |
