The loudest cities in Denmark, ranked by noise exposure

Denmark's 4 ranked agglomerations house 1,840,579 residents. Loudest first, by exposed-resident day-evening-night (Lden) level: Aarhus (55–70 dB), Copenhagen (55–70 dB), Odense (55–70 dB), Aalborg (55–70 dB) — down to Aalborg at 55–70 dB. The median city centres near Lden 62.5 dB. Road traffic is the dominant source in all 4. The most populous, Copenhagen at 1,254,256 residents, ranks #119 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 Denmark 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.
