Strategic noise map 2021 air traffic within major agglomerations - Lnight contours

Strategic noise map for air traffic within major agglomerations according to RL 2002/49/EC. Deurne airport (Antwerp) is the only airport located within a major agglomeration of Flanders. The reference year of these dates is 2021. The noise map shows the annual average noise emission of the flight movements to and from Deurne airport expressed in the parameter Lnight. The Lnight level is the average of the noise levels during the night (23-07h) and is one of the noise indicators that are representative of possible, nocturnal sleep disturbance. These noise maps are updated every 5 years. As of the strategic noise maps with reference year 2021, a new calculation method was used. This is a new common European calculation method that is mandatory for all Member States as of the mapping exercise with reference year 2021. Because this calculation method differs from that used in previous mapping rounds, it is not appropriate to compare the results of reference year 2021 with previous editions (2006, 2011 and 2016). It cannot be ruled out that differences in calculated exposure are solely due to the application of this new calculation method and do not result from increased or reduced exposure.
