Abstract: This study focuses on residential renovation noise complaint data obtained from Shanghai's public complaint and petition hotline. By systematically examining the temporal and spatial patterns of these complaints, it aims to identify the public’s genuine concerns and demands regarding renovation noise. The results indicate that, in terms of spatial distribution, residential renovation noise complaints in Shanghai are mainly concentrated in the central urban area, exhibiting a significant feature of regional agglomeration. In terms of temporal distribution, complaints received on weekends accounted for 45.3% of the total, and those lodged during 7:00–8:00 on workdays were 6.3 times the average of other time periods. These conclusions can provide data support for accurately identifying the key areas and time windows for decoration noise control in Shanghai. They also serve as a reference for improving renovation time regulations, optimizing regionally differentiated management policies, and enhancing the refined management level of the city’s acoustic environment.
