Aircraft noise pollution is increasingly drawing attention, especially in areas surrounding airports. High-decibel noise from takeoffs and landings not only disrupts residents' lives, affecting sleep, study, and work efficiency, but can also pose long-term health risks. Current challenges primarily focus on: insufficient monitoring coverage in some areas, inadequate sound insulation measures in sensitive buildings, limited public awareness of noise control standards, and concerns about the effectiveness of enforcement regulations.
Legal Safeguards: The State Establishes a Legal System for Aircraft Noise Control
At the national level, a legal framework for aircraft noise control has been established, providing a solid basis for protecting residents' rights and ensuring scientific governance.
The Law of the People's Republic of China on the Prevention and Control of Noise Pollution :
Article 88 : It is clearly stipulated that when formulating territorial spatial planning and related plans, people's governments at all levels and their relevant departments shall fully consider the impact of aircraft noise on the surrounding environment, make overall plans, rationally arrange functional layouts , and prevent or mitigate noise pollution.
Article 57 : Airport management agencies, air transport enterprises and general aviation enterprises shall 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 shall meet the prescribed distance requirements. If the requirements are not met, sound insulation and noise reduction measures shall be taken in accordance with the law (such as installing sound barriers or soundproof windows).
Mandatory national standards :
The "Environmental Standard for Aircraft Noise Around Airports" (GB 9660-88) is a core standard that clearly defines the criteria for classifying areas affected by aircraft noise around airports (LWECPN) and the noise limits for different areas . This standard is a key legal benchmark for evaluating whether aircraft noise exceeds the standard and determining the scope of responsibility for prevention and control.
Departmental rules and management standards :
Based on the Noise Law and the Environmental Noise Pollution Prevention and Control Law, the Civil Aviation Administration of China (CAAC) has formulated a series of regulations and technical guidance documents, such as the Guidelines for the Prevention and Control of Noise Pollution at Civil Aviation Airports . These documents detail the specific requirements and operational procedures 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.
Through comprehensive measures, Sanyuan Environment helps create tranquil spaces.
As a professional integrated acoustic environment service provider, Sanyuan Environment understands that effective aircraft noise control requires a multi-dimensional collaborative approach and provides comprehensive technical support to airport management agencies, local governments, and communities.
Precise monitoring and assessment (technical support):
1. Deploy an advanced airport noise automatic monitoring system to collect long-term, continuous, and accurate noise data (in accordance with GB 9660-88 standard), draw noise maps, and accurately locate pollution sources and their impact range.
2. Provide aircraft noise impact prediction and simulation assessment services to provide a scientific basis for planning and site selection and runway usage strategy adjustment (to help implement Article 88 of the Noise Law).
Endpoint Protection Engineering (Core Service):
Key Solution: Tailor-made high-performance soundproof door and window renovation projects for sensitive buildings such as residences, schools, and hospitals affected by excessive noise . Ensuring that the indoor acoustic environment after installation meets the relevant functional area limits in the "Environmental Noise Quality Standard" (GB 3096-2008) (this is a concrete action directly responding to Article 59 of the "Noise Law").
We provide design, consulting and implementation services for projects such as sound barriers and silencers .
Information communication and public services (value extension):
We assist clients in establishing platforms for disseminating aircraft noise information and communicating with the public , thereby increasing information transparency.
We provide science popularization and legal policy dissemination services on aircraft noise to promote public understanding and participation.
Aircraft noise control involves balancing airspace safety, urban development, and residents' rights, making it a complex systemic project. National laws and regulations provide top-level design and bottom-line requirements, but solving the noise problem at the last mile requires close collaboration among all responsible parties and in-depth involvement of professional expertise.
As a comprehensive service provider deeply rooted in the acoustics field, 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 governance solutions for aircraft noise monitoring, consulting, design, production and construction, contributing to the construction of a quiet and harmonious acoustic environment.
