ABSTRACT

In order to create a healthy and comfortable indoor environment, based on the sandwich lightweight partition structure, this article systematically analyzes the impact of factors such as the type of filling material in the partition wall cavity, the thickness of the filling material, the number and quality of panel layers on its sound insulation performance. Through experimental tests, the reverberation chamber method was used to measure the sound insulation amount and the standing wave tube method was used to measure the sound absorption coefficient, and the effects of different filling materials and structural parameters on the sound insulation effect were compared. The results show that filling glass wool or rock wool materials significantly improves the sound insulation of sandwich partition walls, and increasing the thickness of the filling material and the number of panel layers further optimizes the sound insulation performance. The research results provide a theoretical basis for the design of indoor partition walls and help improve indoor acoustic comfort.
