Noise pollution register for railway systems – railway noise, actual daytime emissions
The authoritative railway noise pollution values are defined in the noise pollution register. Both emission and immission values are shown. The actual emissions Lr,e in [dB(A)] were measured based on the actual traffic during the day over the course of one year.
