Dataset description

The data standard covers zoning and geographical boundaries defined as part of an aerodrome exposure plan (PEB), noise discomfort plan (PGS) or strategic noise maps (SRMs) at an aerodrome. Developed on the basis of 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 an EPB is to control urbanisation; • that of a PGS is to identify areas eligible for soundproofing aid; • the purpose of the CSBs 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 zones defined in the context of an EPB (number of 3 or 4): — Zone A: Strong noise zone where the Lden* > 70; — Zone B: Strong noise zone where the Lden < 70 and an external boundary between Lden 68 and 62 (depending on the aerodromes); — Zone C: Moderate noise zone between the outer boundary of zone B and a boundary between Lden 64 and 52 (depending on aerodromes); — Area D: Noise zone between the outer limit of zone C and a limit corresponding to Lden 50; • discomfort zones defined in the context of a PGS: — a very strong zone I of discomfort (included inside the Lden 70 index curve); — a zone II of strong discomfort (included between the index curves Lden 70 and Lden 65. However, where the outer curve of zone B of the approved aerodrome B of the aerodrome is set at a Lden index value of less than 65, that value shall be used for the noise discomfort plane); — a zone III of moderate discomfort (included between the outer limit of zone II and the index curve Lden 55); • noise zones defined in CSBs; these are the areas between the isophone curves drawn from 55 dB(A) in Lden and 50 dB(A) in Ln and, for the higher values, set from 5 dB(A) to 5 dB(A); In each of these areas the populations impacted are estimated and the issues identified for the “Nlue” nuisance (educational or health institution) are identified; • 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 total noise exposure level • L: level (level) • d: day (day) • e: evening (evening) • n: night (night)
