Bergisch Gladbach houses 111,600 people. Its noise-exposed residents experience Lden levels of 55–70 dB by day and 50–65 dB at night, driven mainly by road traffic, which puts it #81 of 314 in the measured European ranking — right at the European median. Among Germany's 72 ranked agglomerations, Bergisch Gladbach is the 42nd-loudest. Across Europe it sits just below Leuven, Belgium (#80) and just above Erlangen, Germany (#82).

The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, so Bergisch Gladbach'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 Germany'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.
