Advances in micro-perforated panel absorbers

摘要: 简述了马大猷教授的微穿孔板基本理论、微穿孔板吸声体在扩散声场以及在高声强环境下的理论要点。比较详细地讨论了30年来与马大猷教授所提理论相对应的实验研究结果及应用发展情况。基于马大猷教授的基本理论,提出了一种新的相关衍生结构——管束微穿孔板。对微穿孔板吸声体的发展趋势做了展望。表明:微穿孔板吸声体将成为新世纪的绿色理想吸声材料。

Abstract: This paper summarizes the advances in micro-perforated panel absorbers in recent years. MAA Dah-You's general theory of micro-perforated panel and the characteristics of the micro-perforated panel absorbers in a reverberation and a high sound intensity field are briefly reviewed. The related experimental research works and applications of the micro-perforated panel absorbers as the consequences of MAA's theory are discussed in details. A new absorbing structure-bundle tube micro-perforated panel based on MAA's general theory has been presented at the first time. It is demonstrated that micro-perforated panel absorbers will be the best potential sound absorbing materials in future.
