机场是现代化城市的标志。机场给人们带来了方便和繁荣,同时也带来了污染和噪声。机场航空噪声影响范围广,噪声烦恼度高,是城市区域环境噪声防治的难题之一。在欧美发达国家的大中型城市中,受机场飞机噪声影响的人数超过了车辆交通噪声影响的人数,排在首位。中国属发展中国家,城市交通噪声问题尚居首位。然而,随着经济发展,机场不断扩建,航班越来越密集,机场噪声的问题也日渐突显。
The airport is a symbol of the modern city. The airport has brought convenience and prosperity to people, as well as pollution and noise. Airport aviation noise has a wide range of impact and high degree of noise annoyance, which is one of the problems in preventing and controlling environmental noise in urban areas. Among the large and medium-sized cities in developed countries in Europe and the United States, the number of people affected by aircraft noise at the airport exceeded the number of vehicles affected by traffic noise, ranking the first place. China is a developing country, and the issue of urban traffic noise still ranks first. However, with the economic development, the airport has been expanding and the flights getting more and more intensive. The problem of airport noise has also become increasingly prominent.
