Strategic Noise Mapping
EU Environmental Noise Directive compliance with agglomeration mapping for cities over 100,000 population. Calculate population exposure and develop noise action plans.
EU Environmental Noise Directive
The EU Environmental Noise Directive 2002/49/EC requires member states to produce strategic noise maps and action plans for major urban areas and transport infrastructure. The directive aims to assess noise exposure, inform the public, and reduce harmful noise levels.
SoundPLAN provides the calculation engine and data management tools needed for large-scale strategic noise mapping projects covering entire cities and transport networks.

CNOSSOS-EU Implementation
Since 2019, the Common Noise Assessment Methods (CNOSSOS-EU) are mandatory for strategic noise mapping in the European Union. SoundPLAN fully implements CNOSSOS-EU for road, railway, aircraft, and industrial noise sources.
The CNOSSOS-EU methods provide harmonized calculation procedures across all EU member states, ensuring comparable results and consistent reporting to the European Environment Agency.
CNOSSOS-EU Source Types
- Road traffic noise (vehicle categories M, N, P)
- Railway noise (trains, trams, metro)
- Aircraft noise (approach, departure, taxiing)
- Industrial noise (point, line, area sources)
