Abstract

Due to favorable sound isolation to the impact sound transmission, People are prone to adopt floating floor as insulation structure. Of the researches on impact sound insulation through a floating floor, the theoretical study is much less than the experiment analysis. For the purpose to determine sound insulation and the dominate sound transmission path through a floating floor, the Statistical Energy Analysis(SEA) is employed to set up a theoretical model for predicting sound transmission across two floor plates connected by a resilient interlayer, and there are two main paths: the stud path and the cavity path. It reveals that the resilient interlayer plays a key role in impact sound insulation of a floating floor, and there exists a good agreement between predicted and measured sound pressure level (SPL) in the rooms below the floors.
