摘要
传统的声电类比法在单层微穿孔板吸声结构中的计算,得到广泛应用,但由于在双层微穿孔板结构中存在较大误差,于是提出用传递矩阵法对微穿孔板吸声结构进行分析。本文对比分析声电类比法与传递矩阵法在微穿孔板结构模型中的应用,从而有效设计微穿孔板吸声结构参数设计的实验方案。
The traditional Electro-Acoustic method have been used for calculation of monolayer micro-perforated-panel acoustic absorber structure is popular widely, however, because of considerable error in the multilayer micro-perforated-panel acoustic absorber structure, we propose to analyze the micro-perforated-panel acoustic absorber structure in transfer matrix method.In this paper, according to the comparison and analysis of some data getting from experiments which use the Electro-Acoustic method and the transfer matrix method in the structure of monolayer layer micro-perforated-panel acoustic absorber structure.
