With 1,977,300 residents, Vienna reports day-evening-night transport noise of 55–75 dB for its exposed population (45–65 dB at night), mostly from road traffic. That is #17 of 314 European cities, above the European median. Among Austria's 5 ranked agglomerations, Vienna is the 1st-loudest. Across Europe it sits just below Vigo, Spain (#16) and just above Ghent, Belgium (#18).

The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, so Vienna's exposed residents run roughly 12 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 Austria'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.
