Strategic Noise Map (CSB) — A L night — Doubs Department

Isophone curves: areas exposed to more than 50 dB(A) according to the Lnight(1) indicator, with a step of 5 in 5 dB(A). (1) Ln to assess exposure to perceived average noise during the night (22h-6h). Production process: Acoustic modelling by NoiseModelling software, developed in partnership between Cerema and UGE-CNRS, and input data from the PlaMADE database established by Cerema. Constraint of use: Information value mapping
