The wall's external panel material had significant effect on the wall's sound insulation property, and the contribution of the wood-plastic panel to the sound insulation was much higher than that of the polyvinyl chloride (PVC) plastic hanging board. The results showed that for the wall that constructed by the WPC as the wall studs, compared with the one that constructed by the pine wood as the wall studs, the deviation of their sound insulation was lower than ± 3 dB. And the sound insulation performance of the walls was studied. Three kinds of structural wood walls integrated with wood plastic composite (WPC) were designed. The sound insulation performance is an important technical index for evaluating the physical property of the building wall.
