摘　　要：在考虑墙体共振和房间共振的基础上 ,应用有限元法对住宅的低频隔声问题进行研究 .对比实验表明 ,计算值和实验值相符 .并且 ,声源室与受声室的体积以及两房间是否对称 ,皆对房间的隔声有影响 .The finite element method was employed to predict the low frequency insulation in dwellings, by considering the resonance of partition and of rooms. There was a good agreement between the measured and predicated data on the differences in the sound pressure level. It was also found that the sound pressure level difference was lower in equal, symmetric room than in unequal, asymmetric room configurations.
