Noise pollution register for railway systems – immissions and noise protection walls

The authoritative railway noise pollution values are defined in the noise pollution register. Both emission and immission values are shown. The permitted noise levels Lr,e in [dB(A)] were fixed by the FOT in a decision. The actual immissions Lr,e in [dB(A)] were measured based on the actual traffic during the night over the course of one year. The built noise protection walls lead to a reduction of immissions. Their effect is taken into account in the immissions.
