Will Shenyang high-speed rail be noisy? Jingang Tianfu

For Shenyang, the high-speed rail is really good, powerful and powerful. However, the noise of high-speed rail is objective. For places close to the railway tracks, it is not only noise, but also the vibration caused by the operation of high-speed rail.

In fact, the noise and air generated by the high-speed operation of EMU are the biggest noise pollution, which can be affected by far and near.

The noise mainly comes from the friction noise of the rear wheel rail, the noise generated by the car and the air at high speed, and the mechanical noise inside the EMU. At present, the common practice is to install muffler, lay damping pad and set up sound barrier. But the final result is indeed up to standard, but the noise still exists and cannot be ignored. This is an unchangeable fact. It depends on the individual's ability and the sound insulation effect of the room.
