With 139,117 residents, Fredrikstad/Sarpsborg reports day-evening-night transport noise of 55–70 dB for its exposed population (50–65 dB at night), mostly from road traffic. That is #85 of 314 European cities, right at the European median. Among Norway's 6 ranked agglomerations, Fredrikstad/Sarpsborg is the 1st-loudest. Across Europe it sits just below Genoa, Italy (#84) and just above Bytom, Poland (#86).
The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, so Fredrikstad/Sarpsborg's exposed residents run roughly 10 dB above the daytime guideline. The figures count road, rail, aircraft and industry only, so sirens, nightlife and construction sit outside the model — which is why measured exposure can differ from a city's reputation for noise.
These are measured values, not estimates: they come from Norway's strategic noise maps reported under the EU Environmental Noise Directive (2022 round) and harmonised by the European Environment Agency. Lden is the annual-average day-evening-night level; only people above the 55 dB Lden reporting threshold are counted, so the range describes the noise-exposed population, not the city's quietest streets.
