Strategic Noise Map (CSB) — A Lden — Doubs Department

Isophone curves: areas exposed to more than 55 dB(A) according to indicator Lden(1).(1) Lden (acronym Level day-evening-night) to assess exposure to average perceived noise in one day. 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等声级线（Isophone curves）：依据Lden指标划定的暴露于55dB(A)以上噪声的区域(1)。 Lden（全称为Level day-evening-night的缩写）用于评估单日平均感知噪声暴露水平。 数据集构建流程：采用由法国公共工程、环境与空间研究院（Cerema）与UGE-CNRS合作开发的NoiseModelling软件开展声学建模，输入数据来自Cerema建立的PlaMADE数据库。 使用限制：信息价值映射（information value mapping）
