Aiming at the current carbon emission problem in the construction industry, a new type of high sound insulation assembled partition wall system is proposed. The system aims to respond to the national energy conservation and carbon reduction policy, improve construction efficiency, reduce costs, and reduce the generation of construction waste by optimizing the internal wall system. The research method the combination of experiment and simulation were adopted to verify the comprehensive performance of the system through laboratory test and field application. System design and material selection were explored, sound insulation performance test were conducted, and comparative analysis with traditional masonry and finished wall panels were carried out, which aims to promote the green and low-carbon transformation of the construction industry, and provide technical support for the sustainability of the economic structure.
