Air traffic noise map, international airports — Lden contours — state 2016

This noise map shows the noise of air traffic around the international airports Brussels Airport, Ostend-Bruges, Kortrijk-Wevelgem and Antwerp. The reference year of these dates is 2016. On the sound card, the annual average noise simulation of the flight movements to and from the airport shall be expressed in the parameter Lden. The Lden level is a weighted annual average sound pressure level over the day where the evening and night levels are relatively heavier, which corresponds to the finding that noise is generally perceived as more nuisance in the evening and at night. European research therefore shows that a Lden is a relatively good predictor of the extent to which local residents may be affected. For the purpose of determining the number of potentially impaired, 55 decibels (dB(A)) are used as the lower limit for air traffic. Since the sound cards are not suitable for analysing in high resolution, only limited zooming can be done on the map. For Brussels Airport comes the data from the strategic noise map (major airports). This strategic noise map, in implementation of the European RL 2002/49/EC, is updated every five years. For the other airports, the noise immission was added as calculated by the KU Leuven (Laboratory Acoustics) on behalf of the airports themselves (annual update).
