Map visualisation service (WMS) of the dataset: Air Noise — Vaucluse (84) — Lot Sheet

The data standard covers zoning and geographical perimeters defined as part of a noise exposure plan (PEB), noise disturbance plan (PGS) or strategic noise maps (CSB) of an aerodrome. Based on a calculation method, databases and input data on infrastructure, traffic and trajectories, PEBs, PGS and CSB define several noise exposure areas around an aerodrome but have three different purposes: • the objective of a PEB is to control urbanisation; • that of a PGS is to determine areas eligible for soundproofing aid; • the purpose of the CSB “... is to assess and prevent noise pollution resulting from human activities, in particular noise emitted by means of transport, road, rail or air traffic...”; This standard distinguishes: • noise areas defined as part of an EPB (3 or 4): — Zone A: Loud noise zone where Lden* > 70; — Zone B: Strong noise zone where the Lden < 70 and whose outer limit is between Lden 68 and 62 (depending on aerodromes); — Zone C: Moderate noise zone between the outer boundary of zone B and a boundary between Lden 64 and 52 (depending on aerodromes); — Zone D: Noise zone between the outer limit of zone C and a limit corresponding to Lden 50; • the areas of discomfort defined in the framework of a PGS: — a zone I of very strong discomfort (included within the Lden 70 index curve); — a zone II of strong discomfort (included between the Lden 70 and Lden 65 index curves. However, where the external curve of zone B of the approved EPB of the aerodrome is set at a Lden index value of less than 65, this value shall be used for the noise disturbance plane; — zone III of moderate discomfort (included between the outer limit of zone II and the Lden 55 index curve); • the noise areas defined in the CSBs; these are the zones between the isophone curves drawn from 55 dB(A) in Lden and 50 dB(A) in Ln and, for the higher values, set 5 in 5 dB(A); In each of these areas are estimated the populations impacted and are identified the issues identified for the nuisance “Noise” (educational or health establishment); • noise curves (or isophone curves) calculated for the determination of zoning; • the one-off elements (health or educational institutions) identified as issues in strategic noise maps. * Lden = Noise index (or indicator) representing the total noise exposure level • L: level (level) • d: day (day) • e: evening (evening) • n: night (night)
