摘要
对微穿孔平板式空间吸声体的吸声特性进行了理论预计,其中运用了半厚度模型分析和四端网络计算方法。计算结果与混响室实测数据符合较好。文中根据预测结果,分析了影响微穿孔平板式空间吸声体吸声性能的诸项主要因素,可为设计应用提供指南。
Sound absorption characteristics of suspended micro-perforated panel are theoretically investigated in this paper. The method of half thickness model of the absorber with quadripole analysis was used for predicting its acoustic performance. Predictions show that they well agreed with the absorption measurements in the reverberation chamber. This paper further discusses the factors affected the absorption characteristics for such absorbers, and suggests some rules as design guidelines.
