Dataset Direct Download Service (WFS): Noise classification sectors affected by the noise of land transport infrastructure in the Charente department. (revision)

Surface objects of the noise classification sectors affected by the noise of the land transport infrastructure of the Charente department. This regulatory noise prevention system defines bands on each side of the sound classification tracks. It is ordered and published by the Prefect pursuant to the Order of 30 May 1996 and Article R571-32 of the Environmental Code, after consulting the municipalities. These areas ranging from 10 metres (category 5) to 300 metres (category 1) are areas where environmental noise levels exceed or are likely to eventually exceed a noise level of 60 dB(A) in daytime expressed in LAeq (6h-22h) due to land transport infrastructure alone. The areas affected by noise will have an impact on the constructions, in particular the acoustic insulation of the facade, and will be reported in the planning documents, without becoming a servitude. LAeq: as the noise level of a source varies over time, it is necessary to calculate the energy average over a given duration (Leq) in order to observe and compare different values. When this value is A-weighted, it is called LAeq (equivalent continuous sound pressure level).
