Name: Niveau de bruit Lden des grands axes ferroviaires en 2006

Display Field: NIV

Type: Raster Layer

Geometry Type: null

Description: Couche de données matriciel représentant le bruit provenant des grands axes ferroviaires en 2006 selon l’indice Lden (L=level, d=day, e=evening, n=night). Il s’agit d’un indicateur du niveau de bruit global pendant une journée (jour, soirée et nuit), moyenné sur une année entière (en l’occurrence 2006). Il représente le niveau d’exposition total au bruit et est utilisé pour qualifier la gêne liée cette exposition
