Boras houses 113,179 people. Its noise-exposed residents experience Lden levels of 50–65 dB by day and 40–60 dB at night, driven mainly by road traffic, which puts it #278 of 314 in the measured European ranking — below the European median — quieter than most cities in the ranking. Among Sweden's 18 ranked agglomerations, Boras is the 17th-loudest. Across Europe it sits just below Leon, Spain (#277) and just above Milan-Monza, Italy (#279).

The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, so Boras's exposed residents run roughly 5 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 Sweden'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.
