The scope of the survey according to END cannot be achieved with conventional measurement methods, therefore a calculation of the noise exposure is explicitly permitted. Measurement and calculation methods are presented below.
In the first reporting rounds, environmental noise mappings were requested to a lesser extent or only above a certain traffic volume.
1st reporting round (2005-2009) | 2nd reporting round (2010-2014) | |
---|---|---|
agglomeration | > 250.000 Residents | > 100.000 Residents |
major road | > 6 million cars/year | > 3 million cars/year |
major railway line | > 60.000 trains/year | > 30.000 trains/year |
major airport | > 50.000 movements per year | > 50.000 movements per year |
Exposure levels are to be determined on the basis of uniform EU-wide parameters over the entire day (day-evening-night noise indicator (LDEN)) and separately for the night (night-time noise indicator (LNight)).
