Will the intercity railway produce noise pollution because it is close to Baoliweizi County?

You don't have to be very close to produce noise pollution. Trains passing on the railway are bound to make noise. If you want to ask about the impact, it depends. Of course, the closer, the greater the impact. But if the sound insulation of the window is better, it should be no problem. It is basically a comfort to rely on the railway sound barrier. The best measure should be to establish a sound-proof channel and completely close the railway. But the cost is very high, and it will not be considered.
