Lden according to European Environmental Noise Directive 2002/49/EC
Only the above-listed incidents of overflights will be included in the noise calculation, which means that the calculated value will be rather poor for stations with bad overflight detection.
The Lden values contain the evening- (+5dB) and night surcharge (+10dB) according to the 'European Environmental Noise Directive'.
