WMS Ambient noise mapping 2017 Round 3

This service presents the noise maps of round 3 for major roads over 3 million vehicles per year, main railway lines with more than 30,000 trains/year, major airports with more than 50,000 flights per year, in agglomerations with more than 100,000 inhabitants, other noise-relevant roads, rail and airports, as well as industry, including ports and other sources of noise, in accordance with Directive 2002/49/EC of the European Parliament and of the Council for North-West traps. Noise effects shown in the maps are not measured, but calculated according to the preliminary calculation methods for ambient noise on rail, road, aerodromes and industry and commerce. (VBUSch, VBUS, VBUF, VBUI). The calculations were carried out in a 10 meter grid and 4 meters high. The displayed noise index LDEN (day-even night noise index) is a physical size for describing the ambient noise. It is calculated from the day noise index (12 day hours, Lday), evening noise index (4 rest hours, Levening) and night noise index (8 night hours, LNight). The noise index LNight is also displayed individually.
