As a comprehensive acoustic environment service provider, Sanyuan Environment is committed to promoting intelligent and refined urban noise management through technological innovation. Recently, the company's Noise Online Team, part of its Technology R&D Department, proposed a "four-dimensional model" solution. This solution empowers a noise mapping system through a comprehensive process of "perception, analysis, decision-making, and feedback," providing a replicable and scalable benchmark for urban acoustic environment management.
The first dimension: global perception - building a precise monitoring network
Sanyuan Environmental leverages its proprietary intelligent sensing equipment (such as micro-stations, central stations, and high-precision sound source location cameras) to build a noise monitoring network covering key areas. The system collects real-time soundprint data from complex scenarios such as traffic routes, square dance areas, and children's playgrounds. Combined with sound source angle location technology, it generates dynamic environmental sound maps. This technological breakthrough not only addresses the high costs and numerous blind spots of traditional monitoring, but also enables precise capture of noise data across time and space, providing reliable support for governance decisions.
The second dimension: Intelligent analysis – AI-driven pollution tracing
The company has developed an intelligent noise recognition engine by deeply integrating AI algorithms with acoustic models. The system automatically determines noise types (such as natural environments, square dancing, and traffic noise) and accurately identifies sources of excessive noise (such as high-frequency noise above 85dB). It then generates pollution heat maps based on attenuation and absorption patterns. This technology, which has been granted multiple patents, helps management departments quickly locate the root causes of problems and improves pollution tracing efficiency by over 60%.
The third dimension: scientific decision-making - dynamic response and precise policy implementation
Based on real-time data, the Three-Element Environmental Noise Map System automatically triggers a tiered early warning mechanism, connecting communities and management departments through audio and visual alarms, text message notifications, and other means. For scenarios where noise levels exceed standards, the system supports dynamic control strategies, such as optimizing square dance hours and adjusting the layout of soundproofing facilities. This shifts governance from passive response to proactive intervention. This solution has been implemented in numerous cities nationwide, helping to reduce community noise complaints by over 40%.
The fourth dimension: collaborative feedback – building a long-term governance ecosystem
Sanyuan Environment has innovatively built a multi-department collaborative governance platform, integrating real-time noise maps with environmental protection, urban management, and community systems to achieve data sharing and a closed-loop system. Residents can participate in oversight through visual maps, and management departments continuously optimize measures based on feedback, creating a "co-governance, co-management, and shared" governance ecosystem. Furthermore, the company's accumulated portfolio of over 100 patents and software copyrights has laid a solid foundation for technological iteration and the development of industry standards.
Conclusion: Technology empowers cities to be quieter
With its "four-dimensional model" at its core, Sanyuan Environment has elevated noise mapping from a monitoring tool to a smart hub for urban acoustic environment management. The company continues to achieve breakthroughs in technological innovation and application scenarios. Going forward, the company will continue to deepen its expertise in acoustics, expand the boundaries of technological application, and contribute its expertise to building livable cities and enhancing residents' well-being.
