Noise Map – Rail – Metropolitan
Average day-and-night noise from railways at 4 metres above ground level, modelled (not measured), for the metropolitan areas of Oslo, Bergen, Trondheim, Stavanger, Sarpsborg, Fredrikstad and Drammen. The maps show the noise situation as it was in 2022. The noise map cannot be used for land-use planning. Source: Miljødirektoratet. Part of Placepoint's map layer for Noise. The strategic noise maps are not updated, but are collected every five years. See Miljødirektoratet: Strategic noise maps.
