With noise mapping technology at its core, a new chapter in urban sound environment management is being opened.

2025-11-04

As a comprehensive acoustic environment service provider, Sanyuan Environment is committed to promoting the intelligent and refined management of urban noise pollution through technological innovation. Recently, the company's Noise Online Team proposed a "four-dimensional model" solution, which empowers the noise mapping system through the entire chain of "perception, analysis, decision-making, and feedback," providing a replicable and scalable benchmark paradigm for urban acoustic environment management.

First Dimension: Comprehensive Perception – Building a Precise Monitoring Network

Sanyuan Environment leverages its independently developed intelligent sensing equipment (such as micro-stations, central stations, and high-precision sound source positioning cameras) to create a noise monitoring network covering key areas. The system can collect soundprint data in real time from complex scenarios such as traffic areas, square dancing areas, and children's playgrounds. Combined with sound source angle positioning technology, it generates dynamic environmental sound maps. This technological breakthrough not only solves the problems of high cost and numerous blind spots associated with traditional monitoring, but also achieves accurate "all-time, all-space" capture of noise data, providing reliable assistance for governance decisions.

Second Dimension: Intelligent Analysis – AI-Driven Pollution Source Tracing

The company has deeply integrated AI algorithms and acoustic models to develop a noise intelligent recognition engine. The system can automatically determine the type of noise (such as natural environment, square dancing, traffic noise, etc.) and accurately identify excessive sound sources (such as high-frequency noise above 85dB), and generate a pollution heat map based on attenuation and absorption patterns. This technology has obtained multiple patent certifications, helping management departments quickly locate the root cause of problems and improving the efficiency of pollution source tracing by more than 60%.

The third dimension: Scientific decision-making – dynamic response and precise policy implementation

Based on real-time data, the Sanyuan Environmental Noise Mapping System can automatically trigger a tiered early warning mechanism, linking communities and management departments through audible and visual alarms, SMS notifications, and other means. For scenarios exceeding noise standards, the system supports dynamically developing control strategies, such as optimizing square dancing times and adjusting the layout of soundproofing facilities, shifting the approach from "passive response" to "proactive intervention." Currently, this solution has been implemented in multiple cities across the country, helping to reduce community noise complaint rates by over 40%.

Fourth Dimension: Collaborative Feedback – Building a Long-Term Governance Ecosystem

Sanyuan Environment has innovatively built a multi-departmental collaborative governance platform, integrating real-time noise maps with environmental protection, urban management, and community systems to achieve data sharing and closed-loop task management. Residents can participate in monitoring through a visual map, and management departments can continuously optimize measures based on feedback, forming a governance ecosystem of "co-governance, co-management, and sharing." In addition, the company's accumulated more than 100 patents and software copyrights have laid a solid foundation for technological iteration and industry standard setting.

Conclusion: Technology empowers cities to be quieter

Sanyuan Environment, with its "four-dimensional model" at its core, has upgraded noise maps from monitoring tools to a smart hub for urban sound environment management. The company continues to make breakthroughs in technological innovation and application scenarios, and will continue to deepen its expertise in the acoustics field, expanding the boundaries of technological applications to contribute its professional strength to building livable cities and improving residents' well-being.
