Flight noise — Level grid LDEN — mapping 2017

The data includes the calculation results of the 2017 environmental noise mapping at the major Bavarian airports Munich and Nuremberg. Noise calculation according to the “Preliminary calculation method for ambient noise at aerodromes (VBUF)” with reference year 2015. 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 the air noise pollution expressed by the LDEN noise index in accordance with the EC Environmental Noise Directive.
