The Noise Level Analysis of Hybrid of Passenger-Freight Railway based on On-line Automatic Monitoring System

Abstract

Abstract A large amount of data is accumulated from the German railway noise on-line monitoring system, which is online for the first time since 2019. In this paper, the monitoring system is introduced simply. By collating and analysing the monitoring data of the last year, overall noise level of current hybrid of passenger-freight railway in Germany and noise level of each measuring station is given for the first time respectively. Finally it is pointed out that the flow of freight is the key factor affecting the noise level of each station. It provides a basis for the follow-up research on the optimization of train traffic volume based on noise level.
