Prediction on coincidence effect of sound insulation of light-weight walls

LIU Jun,HUANG Xianfeng,YANG Yan(College of Civil and Architectural Engineering,Guangxi University,Nanning 530004,China)  
Coincidence effect which occurs within a frequency range will impairs the sound insulation of a wall.For the purpose to predict the phenomenon of coincidence effect that is unlikely predicted theoretically by the Mass Law,the Statistical Energy Analysis(SEA) theory are adopted in studying coincidence effect of sound insulation of a single-leaf wall.The comparison among predicted by SEA,by Mass Law and measured was performed.Therefore,the comparison results indicate that sound insulation prediction by SEA is more precise and agree with the measured date properly.Moreover,the coincidence effect and its effect on sound insulation were appropriate predicted by SEA.Eventually,it is likely to select appropriate building materials and configuration to achieve a comfort sound environment theoretically.
