Comparison between Chinese Code and Eurocode on the impact sound insulation requirements of the residential floor

Abstract

At present, the impact sound insulation performance of the residential floor attracts increasing attention, which is a critical index to evaluate the physical performance of the residential building. Improving the sound insulation performance is an effective measure to improve the living quality and solve the contradictions between neighbors. Therefore, many sound insulation standards have been established to guide the design of building sound insulation. In this paper, comparisons between Chinese code and Eurocode on the impact sound insulation requirements of the residential floor were presented, including the evaluation parameter and the limit value of sound insulation. In addition, the applicability of limit value of sound insulation standard for each country was analyzed in detail through the existing experimental data of different floor structures, and then reasonable suggestions were put forward.
