The loudest cities in Norway, ranked by noise exposure

Norway's 6 ranked agglomerations house 2,112,007 residents. Loudest first, by exposed-resident day-evening-night (Lden) level: Fredrikstad/Sarpsborg (55–70 dB), Drammen (55–70 dB), Oslo (55–70 dB), Trondheim (55–70 dB), Bergen (50–70 dB), Stavanger/Sandnes (50–70 dB) — down to Stavanger/Sandnes at 50–70 dB. The median city centres near Lden 62.5 dB. Road traffic is the dominant source in all 6. The most populous, Oslo at 1,120,927 residents, ranks #182 across Europe with exposed-resident Lden of 55–70 dB. The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, which most of these Norway cities exceed for their noise-exposed residents.

These are measured values, not estimates — strategic noise maps reported under the EU Environmental Noise Directive (2022 round), harmonised by the European Environment Agency, covering road, rail, aircraft and industry. Lnight, the night-time figure, is the level most closely tied to sleep disturbance, which is why the EU reports it separately from the daytime Lden.
