data consultation service (WMS) from: Strategic Noise Map 2012 (second deadline) — Type C map — Ln 65 (for railways)

The strategic noise maps, in accordance with European Directive 2002/49/EC of 25 June 2002, allow for the overall assessment of exposure to noise in the environment. They allow a representation of noise levels, but also to enumerate the exposed population, quantify the nuisances, and then draw up action plans. The type “c” map represents the isophone curves of the areas where the Ln exceeds the value of 65 dB(A) for railways. LN 65 dB(A): zone where Ln (Level night) exceeds 65 dB(A) DB(A) is a unit of measurement expressing a level of intensity (decibel) weighted according to the physiological characteristics of the human ear.
