Abstract：The new vitality of the city through the transformation of the old city, and the noise generated by the construction of the city has become one of the important factors that affect the healthy life of the surrounding residents. Based on literature review and interview examination, this study summarizes three basic risk factors and 16 risk factors, and compares and calculates risk indicators using expert scoring method and analytic hierarchy process. The study found that the noise risk caused by urban construction mainly focuses on the sensitivity of the surrounding environment and the organization of the construction process. The long duration of continuous operation and the proximity to the surrounding buildings are the main factors that cause noise pollution in urban construction. In the construction process, there are many kinds of vehicle noise, living sounds formed by personnel activities, and many kinds of mechanical construction. Finally, in view of the main sources of noise, this paper puts forward suggestions for the prevention and control of noise pollution such as reducing noise from sources and setting up noise isolation zones, which are complementary to traffic regulations and urban planning, in order to improve the urban construction process. The quality of life of the surrounding residents provides support.
