Clermont-Ferrand houses 291,800 people. Its noise-exposed residents experience Lden levels of 55–70 dB by day and 50–60 dB at night, driven mainly by road traffic, which puts it #141 of 314 in the measured European ranking — right at the European median. Among France's 34 ranked agglomerations, Clermont-Ferrand is the 12th-loudest. Across Europe it sits just below Brunoy, France (#140) and just above Goettingen, Germany (#142).
The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, so Clermont-Ferrand'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 France'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.
