I. The Necessity of Governance
Health and quality of life issues
Airport noise has a significant impact on the health of nearby residents, especially those who are chronically exposed to high noise levels. Studies have shown that aircraft noise can lead to sleep disorders, cardiovascular disease, and cognitive decline. For example, the International Civil Aviation Organization (ICAO) states that nighttime noise levels exceeding 55 decibels can significantly increase health risks for residents. Noise levels in some areas surrounding airports in my country have long exceeded standards, necessitating systematic management to reduce the burden on public health.
The objective pressure of airport expansion and a surge in air traffic
With the rapid development of the civil aviation industry, the number of airports and flight density in my country have continued to grow. In 2024, the passenger throughput of civil aviation had recovered to pre-pandemic levels, with some hub airports (such as Beijing Daxing and Shanghai Pudong) handling more than 1,000 flights per day. The noise from aircraft takeoffs and landings, combined with ground traffic noise, has exacerbated conflicts around airports, making environmental remediation an urgent need.
Mandatory requirements for aligning regulations with international standards
The International Civil Aviation Convention (ICAO Annex 16) explicitly requires all countries to develop aircraft noise standards, and 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 its airlines' international route operations due to non-compliance with environmental standards.
Public environmental awareness and complaints surge
In recent years, the proportion of noise complaints at airports has been rising year by year. For example, in 2023, the number of complaints from residents around Guangzhou Baiyun Airport increased by 35% year-on-year, and some communities even saw group protests. The noise problem has escalated from a technical issue to a social governance issue, forcing policies to be implemented more quickly.
II. The Core Significance of Governance
Ecological protection and environmental quality improvement
Airport noise control is a crucial component of the 14th Five-Year Plan for noise pollution prevention and control. By delineating noise-sensitive areas, optimizing flight procedures, and promoting low-noise aircraft, we can reduce interference with the ecological environment (such as bird habitats) and acoustic functional zones, thus contributing to the goal of building a "Beautiful China."
Resolving social conflicts and improving people's livelihoods
Systematic governance can significantly reduce disturbances to residents' lives and improve the livability of communities. For example, Beijing Capital International Airport has increased the indoor noise compliance rate for 100,000 residents in the surrounding area from 60% to 92% by installing soundproof windows and adjusting the proportion of night flights. Such practices can enhance public acceptance of civil aviation development and reduce social conflicts.
Promote technological innovation and industrial upgrading
Monitoring technology: The surge in demand for research and development of equipment such as real-time noise monitoring systems and acoustic sensors is driving the development of the domestic high-end instrument industry.
Noise reduction technology: Breakthroughs in areas such as new aero-engine noise reduction design, flight path optimization algorithms, and airport sound barrier materials can form technological barriers and enhance the competitiveness of my country's aviation industry chain.
Digital governance: The integration of noise data with a 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 management, has reduced the affected population by 40% while ensuring flight growth, creating space for coordinated regional economic development. Furthermore, green airport certifications (such as the Airports Council International (ACI)'s "carbon neutrality" standard) will enhance the international competitiveness of Chinese airports.
International discourse power and standard leadership
By establishing globally leading noise control standards (such as stricter restrictions on nighttime flights), my country can gain the initiative in the formulation of international civil aviation regulations. Meanwhile, if domestically produced aircraft such as the C919 obtain low-noise certification, it will enhance their acceptance in the global market.
III. Case Evidence
Shenzhen Bao'an Airport: By installing a distributed noise monitoring system to track noise sources in real time and optimize flight take-off and landing routes, the number of complaints decreased by 50% year-on-year in 2024.
International experience: London Heathrow Airport's "noise charge" mechanism, which imposes additional landing fees on high-noise flights, has encouraged airlines to proactively switch to low-noise aircraft, providing a policy reference for my country.
Summarize
Airport noise control is not only a technical issue, but also a strategic matter involving public health, social equity, industrial upgrading, and international competitiveness. Through policy guidance and technological empowerment, my country hopes to reduce its environmental burden while cultivating a new noise control industry, achieving a win-win situation for both ecological and economic benefits. In the future, it is necessary to further refine the responsibilities of the main stakeholders (such as the division of labor among airlines, airports, and air traffic control departments) and explore market-based compensation mechanisms (such as noise pollution rights trading) to promote the in-depth development of the noise control system.
