data download service (WFS) from: Strategic Noise Map 2012 (second deadline) — Map type a — Lden
Description
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 “a” map locates the noise-exposed areas, using Lden isophones in steps from 5 in 5 from 55 dB(A) to more than 75 dB(A).
Le Lden (Level day, evening, night) is an indicator of hour-weighted noise discomfort (day, evening and night)
DB(A) is a unit of measurement expressing a level of intensity (decibel) weighted according to the physiological characteristics of the human ear.
