With 195,278 residents, Liege reports day-evening-night transport noise of 50–70 dB for its exposed population (50–65 dB at night), mostly from road traffic. That is #247 of 314 European cities, below the European median — quieter than most cities in the ranking. Among Belgium's 7 ranked agglomerations, Liege is the 5th-loudest. Across Europe it sits just below Espoo, Finland (#246) and just above Stavanger/Sandnes, Norway (#248).

The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, so Liege's exposed residents run roughly 7 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 Belgium'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.
