中文摘要:
      板振动对微穿孔板吸声体的声学特性存在一定的影响.文章对此影响关系从理论方面进行初步分析,并通过不同材料、不同孔径、不同穿孔率样品在低频、中频驻波管中的大量实验,分析板振动对微穿孔板吸声体吸声性能影响关系的规律性,从而得到对微穿孔板的实际应用具有指导性的结论.
英文摘要:
      The panel resonance always affects the absorption characteristics of microperforated-panel(MPP)absorber.In this paper,the theoretical analysis of the effort is made.And through lots of experiments of MPP,different materials,different diameter of perforations,different percentage of perforated area,under intermediate frequency and lower frequency standing tubes,the rules of the effort are discussed.So some practical solutions are obtained.
