I. The Necessity of Governance
Health and quality of life issues
Airport noise has a significant impact on the health of nearby residents, particularly those exposed to prolonged high-noise environments. Studies have shown that aircraft noise can lead to sleep disorders, cardiovascular disease, cognitive decline, and other problems. For example, the International Civil Aviation Organization (ICAO) states that nighttime noise levels exceeding 55 decibels can significantly increase health risks. Some areas surrounding Chinese airports have long exceeded noise standards, necessitating systematic governance to reduce the public health burden.
Objective pressure from airport expansion and surging air traffic
With the rapid development of the civil aviation industry, the number of airports and flight density in my country continue to grow. By 2024, civil aviation passenger throughput had returned to pre-pandemic levels, with some hub airports (such as Beijing Daxing and Shanghai Pudong) experiencing average daily flights exceeding 1,000. Aircraft takeoff and landing noise, combined with ground traffic noise, has exacerbated conflicts around airports, necessitating urgent action.
Mandatory requirements for international compliance with regulations
The Convention on International Civil Aviation (ICAO Annex 16) explicitly requires countries to establish aircraft noise standards. European and American countries have established mature airport noise control systems. As the world's second-largest aviation market, my country urgently needs to improve its standards system to fulfill its international obligations and avoid restrictions on international airline operations due to substandard environmental performance.
Public environmental awareness and complaints surge
In recent years, the proportion of airport noise complaints has been increasing year by year. For example, in 2023, the number of complaints from residents near Guangzhou Baiyun Airport increased by 35% year-on-year, even sparking mass protests in some communities. The noise issue has escalated from a technical issue to a social governance issue, forcing the accelerated implementation of policies.
II. The Core Significance of Governance
Ecological protection and environmental quality improvement
Airport noise control is a key component of the 14th Five-Year Plan's noise pollution prevention and control campaign. By designating noise-sensitive areas, optimizing flight procedures, and promoting low-noise aircraft, these technologies can reduce interference with ecological environments (such as bird habitats) and acoustically functional zones, contributing to the goal of building a "Beautiful China."
Resolving social conflicts and improving people's livelihood
Systematic governance can significantly reduce disruption to residents' lives and improve community livability. For example, by installing soundproof windows and adjusting the proportion of nighttime flights, Beijing Capital Airport has increased the indoor noise compliance rate for 100,000 residents in the surrounding area from 60% to 92%. Such practices can strengthen public support for civil aviation development and reduce social conflict.
Promote technological innovation and industrial upgrading
Monitoring technology: The surge in demand for research and development of real-time noise monitoring systems, acoustic sensors and other equipment has driven the development of the domestic high-end instrument industry.
Noise reduction technology: Breakthroughs in new aircraft engine noise reduction design, flight path optimization algorithms, airport sound barrier materials and other fields can form technical barriers and enhance the competitiveness of my country's aviation industry chain.
Digital governance: The integration of noise data and the smart airport management platform provides a model for refined urban governance.
Sustainable development of the economy and aviation industry
Noise control can reduce obstacles to airport expansion and unlock the potential of airspace resources. For example, Shanghai Hongqiao Airport, through noise zoning, has reduced the number of people affected by the airport by 40% while ensuring flight growth, creating space for coordinated regional economic development. Furthermore, green airport certifications (such as the Airports Council International (ACI) "Carbon Neutral" standard) will enhance the international competitiveness of Chinese airports.
International discourse power and standard leadership
By developing world-leading noise control standards (such as stricter night flight restrictions), my country can seize the initiative in international civil aviation rule-making. Furthermore, if domestically produced aircraft such as the C919 pass low-noise certification, their acceptance in the global market will be enhanced.
III. Case Evidence
Shenzhen Bao'an Airport: By installing a distributed noise monitoring system, tracking noise sources in real time and optimizing flight take-off and landing paths, the number of complaints in 2024 decreased by 50% year-on-year.
International experience: London Heathrow Airport adopts a "noise charge" mechanism, imposing landing and takeoff fees on high-noise flights, encouraging airlines to proactively replace their aircraft with low-noise models, and providing policy reference for my country.
Summarize
Airport noise control isn't just a technical issue; it's a strategic one, encompassing public health, social equity, industrial upgrading, and international competition. Through policy guidance and technological empowerment, my country has the potential to reduce the environmental burden while fostering a new noise control industry, achieving a win-win situation for both ecological and economic benefits. Going forward, further refinement of responsibilities (e.g., the division of labor among airlines, airports, and air traffic control authorities) and the exploration of market-based compensation mechanisms (e.g., noise pollution rights trading) are needed to further develop the governance system.
