摘要

近年来出现了一种新的多孔材料理论，它在很大程度上不同于传统理论。本文通过参考文献对新理论进行实验和理论验证，分析了多孔材料厚度与入射声波频率之间的关系，以进一步探讨新理论。结果表明，新的吸声理论对多孔材料的吸声机理研究具有重要意义，在实际应用中具有重要的应用价值。

Further proof for the theory of elastic sound absorption about flexible porous materials

A new theory about porous materials has evolved in recent years, and it differs from traditional theories to a large extent. In this paper, by referring to documents to test the new theory experimentally and theoretically, we make analysis of the relationship between thickness of porous materials and the frequency of incident sound wave, so as to further discuss about the new theory. Results prove that the new sound absorption theory is of great significance in the sound absorption mechanism of porous material and very useful in practical application.
