Urban noise pollution has become a prominent issue affecting residents' health and urban livability. According to the China Noise Pollution Prevention and Control Report (2025), noise complaints in prefecture-level and above cities accounted for 59.2% of total environmental complaints in 2024, and the nighttime compliance rate of Class 4a functional zones remained low in 2025. Traditional monitoring methods are incompetent for refined needs. This paper proposes an intelligent noise monitoring and tracking system based on drones, integrating multi-sensor modules to achieve synchronous data collection and real-time transmission. Applied in practice, the system significantly improves the efficiency of noise source localization and tracing, providing technical support for the scientific control of urban noise pollution.
