Experimental Research and Theoretical Analysis of Acoustic Insulation for Expanded Polystyrene-Concrete Composite Board

The new structural form and material of Expanded Polystyrene-Concrete composite board not only realize precast and industrialization of green building, but also have good acoustic insulation and heat-shielding performance. This paper is focused on the acoustic insulation of Expanded Polystyrene-Concrete composite board through acoustic experiment. The experimental results were compared with the results from the acoustic transfer method, modal analysis method, and finite element method. The acoustic transfer method was improved to satisfy the design requirement of green buildings and the green reconstruction of existing buildings.
