Number of people exposed to average day-evening-night noise levels (Lden) ≥ 55 dB in Europe

Urban agglomerations are defined as in the Environmental Noise Directive as that the part of the territory, delimited by the Member State, that has a population in excess of 100 000 persons and a population density such that the Member State considers it to be an urbanised area.
The numbers of people exposed can only be summed for the same source inside and outside urban areas and not across sources, since the latter could lead to double counting.
55 dB Lden is the EU threshold for excess exposure defined in the Environmental Noise Directive and indicating an annual average level during the day, evening and night; dB=decibel.
Total values at EU-28 and EEA-33 level per noise source are gap filled.
