1, noise hazard. The friction between high-speed rail wheels and rails produces noise, which affects residents' rest and life.
2. Dust hazard. Trains passing at high speed will raise dust and blow to residential buildings with the wind.

Strengthen the prevention and control of traffic noise pollution and fully implement the technical policy for the prevention and control of ground traffic noise pollution. Noise barriers should be built on both sides of roads such as elevated roads, expressways, expressways and urban tracks in areas where noise-sensitive buildings are concentrated (hereinafter referred to as "sensitive areas"), and measures such as no sound, current limit and speed limit should be strictly implemented. Accelerate the construction of urban railway crossings to interchanges, and gradually cancel the urban grade crossing. Control the noise pollution of urban high-speed rail operation. Strengthen the prevention and control of noise pollution around the airport and reduce disputes over aviation noise disturbing people.
In the capital subway, railway, expressway and areas where various modes of transportation are mixed, the reporter recently found that the noise generated by traffic operation has already affected the normal life of some residents. Among them, the noise problem is particularly prominent in some areas along the subway 13 line, Line 5 and Batong line, as well as in some sections of the southwest third ring road, fourth ring road and some fast connecting lines.
Install hollow glass windows, triple-layer glass windows, vacuum glass windows, sound insulation sealing strips, etc. This can reduce the external noise by half, especially for office buildings and families facing the street, and the effect is ideal.
Install steel doors for sound insulation. Steel doors also contribute to sound insulation. For example, galvanized steel doors have air design in the middle layer, so it is difficult to transmit sound indoors and outdoors. In addition, the steel door is attached with a rubber edge, which will not make noise when contacting the door body.
