墙角节点声传递机理的探讨

Discussion on sound transmission through corner junction

对建筑中墙角节点的声传递进行了理论分析 ,计算了其声透射系数和隔声量 .计算结果和实验测试有良好的一致性 。

Based on the acoustical properties of wall corner junction, theory analysis is employed to model sound transmission through junction, and then the transmission coefficient between two walls of junction has been calculated. There is good agreement between theory prediction and measurement.
