Noise in agglomerations — Railroads — Level grid LNight

The data include the calculation results of the 2017 environmental noise mapping in the agglomerations in Bavaria. These are all cities in Bavaria with more than 100,000 inhabitants, i.e. Munich, Nuremberg, Augsburg, Fürth, Erlangen, Würzburg, Regensburg and Ingolstadt. In each agglomeration, noise was covered by road transport, industrial and commercial installations in accordance with Directive 2010/75/EU of 24.11.2010 on integrated prevention and reduction of environmental protection (IED) and, where available, tram and above ground metro traffic. The noise indices LDEN and LNight in dB(A) are used as a measure of general nuisance or as a measure of sleep disturbances. The LDEN level is a 24-hour averaged immission level determined from the levels Lday, Levening and LNight for the assessment periods day (6:00-18:00), evening (18:00-22:00) and night (22:00-6:00). Weight factors of 5 dB(A) for the four-hour evening time and 10 dB(A) for the eight-hour night time take into account the increased noise sensitivity during these times. The layer represents noise pollution on tramways and above ground metro lines in the agglomeration expressed by the noise index LNight in accordance with the EC Environmental Noise Directive.
