Aircraft noise nuisance is a growing concern, particularly in areas surrounding airports. High-decibel aircraft noise not only disrupts residents' well-being, affecting sleep, learning, and work efficiency, but can also pose long-term health risks. Current pain points include insufficient monitoring coverage in some areas, inadequate soundproofing of sensitive buildings, limited public awareness of noise control standards, and concerns about the effectiveness of regulatory enforcement.
Regulatory protection: China builds a legal system for aircraft noise control
A legal framework for aircraft noise management has been established at the national level, providing a solid basis for protecting residents' rights and interests and ensuring scientific management:
Noise Pollution Prevention and Control Law of the People's Republic of China :
Article 88 : It is clearly stipulated that people's governments at all levels and their relevant departments should fully consider the impact of aircraft noise on the surrounding environment when formulating national land space planning and related plans , make overall plans, and reasonably arrange functions to prevent or reduce noise pollution.
Article 57 : Airport management agencies, air transport enterprises and general aviation enterprises are required to take measures such as optimizing take-off and landing procedures, improving aircraft noise control, and rationally planning flight routes to prevent and control aircraft noise pollution .
Article 59 : It is clearly stated that the construction of noise-sensitive buildings around airports must comply with the prescribed separation distance requirements . If they do not meet the requirements, sound insulation and noise reduction measures (such as installing sound barriers or soundproof windows) should be taken in accordance with the law.
Mandatory national standards :
Aircraft Noise Environmental Standards around Airports (GB 9660-88) : This core standard clearly defines the criteria for demarcating areas affected by aircraft noise around airports (LWECPN) and the acoustic environment limits for each area . This standard serves as a key legal benchmark for evaluating whether aircraft noise exceeds standards and determining the scope of responsibility for prevention and control.
Departmental regulations and management specifications :
The Civil Aviation Administration of China (CAAC) has formulated a series of regulations and technical guidance documents, including the "Guidelines for the Prevention and Control of Noise Pollution at Civil Aviation Airports ", in accordance with superior laws such as the "Noise Law" and the "Law on the Prevention and Control of Environmental Noise Pollution". These regulations detail specific requirements and operating specifications for airport planning and site selection, flight procedure optimization, aircraft airworthiness management, airport noise monitoring and information disclosure, and the implementation of sound insulation and noise reduction projects.
Sanyuan Environment helps create a quiet space with comprehensive measures
As a professional comprehensive acoustic environment service provider, Sanyuan Environment understands that effective aircraft noise control requires coordinated efforts from multiple dimensions, and provides comprehensive technical support to airport management agencies, local governments, and communities:
Precision monitoring and evaluation (technical support):
1. Deploy an advanced automatic airport noise monitoring system to conduct long-term, continuous, and accurate noise data collection (according to GB 9660-88 standard), draw noise maps, and accurately identify pollution sources and impact areas.
2. Provide aircraft noise impact prediction and simulation assessment services to provide a scientific basis for site planning and runway usage strategy adjustments (helping to implement Article 88 of the Noise Law).
Terminal protection engineering (core service):
Key Solution: Tailor-made high-performance soundproofing door and window retrofits for sensitive buildings like residences, schools, and hospitals affected by excessive noise levels . This ensures that the indoor acoustic environment after installation meets the limits for relevant functional areas as specified in the "Noise Environment Quality Standard" (GB 3096-2008). This is a direct response to Article 59 of the Noise Law.
Provide design, consulting and implementation services for noise barriers, mufflers and other projects .
Information communication and public service (value extension):
Assist clients in establishing a platform for aircraft noise information release and public communication to improve information transparency.
Provide aircraft noise science popularization and regulatory policy publicity services to promote public understanding and participation.
Aircraft noise control involves balancing multiple factors, including airspace safety, urban development, and resident rights, and is a complex, systematic project. National laws and regulations provide top-level design and baseline requirements, but addressing noise issues at the last mile requires close collaboration among all responsible parties and in-depth involvement of professional expertise.
As a comprehensive service provider deeply engaged in the field of acoustics, Sanyuan Environment will continue to invest in technological innovation and service optimization, and is committed to providing airports, communities and management agencies with efficient, compliant and customized engineering management solutions for aircraft noise monitoring, consulting, design, production and construction, contributing to the construction of a quiet and harmonious acoustic environment.
