T型建筑节点的声透射(英文)

Sound Transmission through the T-Junction of Building

T型建筑节点广泛存在于房间的墙体之间、墙体与楼板之间,其声传递的机理与墙(楼)板中的不同,因此对其声透射的计算是预测建筑结构及侧向传声的关键之一,本文研究了T型节点的声传递的机理和实验测试方法,进而探讨如何改善节点隔声的途径,即通过调整组成T型节点的板的厚度比,以获得理想的隔声效果.

T-junctions exist between walls and between wall and floor within the building structure,its sound transmission theory is different from transmission through the panels or slabs.So,the calculation of its sound transmission coefficient is one of the keys to predict the sound transmission through whole structure and flank transmission.In this paper,the study on the sound transmission through T-junction and measurement is presented,furthermore,the approaches how to improve sound insulation are also discussed here,that is,the better sound insulation should be obtain by adjusting the thick ratio between plates in the junction.
