双层墙隔声量的SEA预测

双层墙隔声是一种对隔声要求高的建筑隔声措施，但缺乏理论预测，无法在施工阶段处理好隔声问题，本文作者应用统计能量分析（SEA）来预测双层墙结构的隔声问题，并对两墙基础分离与否对隔声的影响进行了研究。在这两种情况下，理论计算值与实测值符合得很好，说明了合理的SEA模型可以应用于双层墙隔声结构的隔声量预测。

Prediction of sound insulation to double-panel structure

In order to obtain high requirement of sound insulation,double-panel structure is often desirable.Due to no theories to predicted sound insulation accurately,it is impossible to deal with sound insulation during construction stage.By using the Statistical Energy Analysis(SEA) method,the prediction of sound insulation to double walls structure will be obtaining.Moreover,the studies on the situations whether the foundation of double-panel is separated or not which affect the sound insulation,have been presented here.The research has been shown that the reasonable SEA model is available for prediction of sound insulation to double-panel structure.
