Road noise - Exposed areas, from 22h to 6h (indicator Ln)

Description

**Strategic Noise Mapping** Data produced by Impédance ingénierie on behalf of the metropolis Aix-Marseille Provence ** ** On the map, geographic shapes have been simplified to optimize the display of the layer. The entire layer, without simplifying geographic shapes, is available in SHAPE format in the Export/Alternative Exports tab. **** The symbology associated with the noise map is available in the attachment part, in QGIS format. Road noise according to indicator Ln for type A maps on the Aix-Marseille Provence Metropolis. Calculation results of acoustic modelling. Type A map locates areas exposed to noise. The value of the noise index Ln ‘Level night’, expressed in A-weighted decibels (dB(A)), represents the level of noise exposure during the night.
