Research review on environmental noise in metro depot induced by train operation

The noise caused by the train operation in metro depot area have an impact on people's normal rest and work. In order to deepen the understanding of the impact on the environmental noise in metro depot area, this paper statistically analyzes the influence characteristics of the noise generated in the train operation in metro depot based on the field testing data. The results show that the noise effects of different segments are different even for the same type of rail line. Considering the characteristics of each area of the metro depot, the noise effects of different regional lines and even different sections of the same lines are different. The noise in metro depot is affected by many factors, which leads to some dispersion and randomness in the test results of the same line.
