多孔声学材料复波数的声管测量方法
Measuring Porous Acoustic Material\\\
推导了表征均匀的、各向同性的声学材料声传递特性的传递矩阵表达式，以及传递矩阵与材料前后表面的声压、质点振速的关系。研究了在声管中采用四传感器法测量材料前后表面声压和质点振速的方法，从而获得完整的测量声学材料中声速和声衰减系数测量方法，为多孔声学材料的复波数的测量提供了一种可行的新方法。
he paper deduced the transfer-matrix of homogeneous and isotropic acoustic material, and the relationship between the transfer-matrix and the sound pressure and particle velocity on the surfaces of the acoustic material, study the methods of measuring the sound pressure and particle velocity on the surfaces of the material in wave tube. Then, the whole approach has been completed in theory. A new method is established for porous material’s acoustic parameters measuring.
