Noise in agglomerations — Road traffic — Level grid LNight — mapping 2022
Description
The data include the calculation results of the 2022 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 facilities in accordance with Directive 2010/75/EU of 24.11.2010 on Integrated Pollution Prevention and Control (IED Directive) and, where available, by tram and above-ground underground transport. Noise calculations are carried out in accordance with the “Calculation method for ambient noise from near-ground sources (roads, rail, industry and commerce) (BUB)”. The noise indices LDEN and LNight in dB(A) are used as a measure of general harassment or as a measure of sleep disturbance. The LDEN level is an emission level averaged over 24 hours, calculated from the levels Lday, Levening and LNight for the assessment times day (6:00-18:00), evening (18:00-22:00) and night (22:00-6:00). Due to weight factors of 5 dB(A) for the four-hour evening time and 10 dB(A) for the eight-hour night time, the increased noise sensitivity during these times is taken into account. The layer represents noise pollution on roads in the agglomeration, expressed by the LNight noise index in accordance with the EC Environmental Noise Directive.
