In the supervision of noise pollution prevention and control, noise mapping technology has made remarkable progress. European countries have legislated to support the creation and application of noise maps, such as the EU's Noise Directive, which mandates member states to develop noise maps and corresponding action plans. Technologically, improvements in realtime monitoring and dynamic updating capabilities, integrated with Geographic Information Systems (GIS), have enabled noise mapping more effective in refined management. Despite being a late starter, China has made progress in research of data collection, analytical processing, and visualization. In this paper, through analysis of the deficiencies in data quality, technical standards, and regulatory systems in China, the following recommendations are made, including strengthening data collection and sharing, establishing unified technical standards, and improving the legal framework. In the future, propelled by policy guidance and technological innovation, noise mapping technology is expected to provide more effective tools for urban noise management in China.
