In addition, the device has the advantages of simple structure, low cost, high reliability and the like, is easy to operate and maintain, and can be popularized to the fields of ground traffic noise control, industrial noise control and the like so as to realize a wide application range.

Description

technical field [0001] The invention belongs to the technical field of civil aviation, and in particular relates to an airport auxiliary facility. Background technique [0002] In today's world, the development of civil aviation has become one of the important symbols of modern human civilization, and airports have gradually become the symbols of modern cities. However, while air transportation has brought convenience and prosperity to cities, it has also brought a series of environmental problems, the most serious of which is aviation noise pollution. With the gradual improvement of people's awareness of environmental protection, the attention to aviation noise at airports is also increasing. The conflict between the airport and the surrounding residents has become very intense, even to the point of irreconcilability, so the problem of aviation noise pollution at the airport has become a worldwide problem. Especially with the rapid development of the aviation industry, ai...
