摘要

分析了聚酯纤维机织物在背后有空气层时的吸声频谱规律以及测试时材料对管内驻波的影响。将传统吸声材料的Zwikker 和Costen 理论、毛细管吸声理论、微穿孔板吸声理论以及穿孔板共振吸声理论应用于材料特性分析

发现Zwikker 和Costen 理论可以定性的给出与实测情况相吻合的材料吸声系数随频率的变化规律。穿孔板共振吸声理论可以推导出与实测情况很接近的材料第一吸声峰值频率。另外

毛细管吸声理论和微穿孔板吸声理论不适合于背后有空气层时聚酯纤维织物的吸声情况。

Abstract

This paper discussed the sound absorption properties of polyester fabric backed with cavity.In our study

different theory was applied to explain the properties of polyester fabric backed with cavity.The conclusion is that the stand wave in the tube will not change their frequency and phase by the absorption of fabric

the Zwikker and Costen theory can give the absorption law at different frequency roughly

the first maximum sound absorption coefficient frequency can be got by the perforated resonance theory.The capillary sound absorption theory and microperforated resonance theory is not agree with the practice of polyester fabric.
