Belgium's 7 ranked agglomerations house 2,636,797 residents. Loudest first, by exposed-resident day-evening-night (Lden) level: Bruges (55–75 dB), Ghent (55–75 dB), Antwerp (55–70 dB), Leuven (55–70 dB), Liege (50–70 dB), Charleroi (50–70 dB), Brussels (45–65 dB) — down to Brussels at 45–65 dB. The median city centres near Lden 62.5 dB. Road traffic is the dominant source in all 7. The most populous, Brussels at 1,222,637 residents, ranks #310 across Europe with exposed-resident Lden of 45–65 dB. The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, which most of these Belgium cities exceed for their noise-exposed residents.
These are measured values, not estimates — strategic noise maps reported under the EU Environmental Noise Directive (2022 round), harmonised by the European Environment Agency, covering road, rail, aircraft and industry. Lnight, the night-time figure, is the level most closely tied to sleep disturbance, which is why the EU reports it separately from the daytime Lden.

Which Belgium cities are the noisiest?
By this EEA data the noisiest Belgium cities are the same as the loudest, since "noisiest" here means measured road, rail, aircraft and industrial exposure: Bruges, Ghent, Antwerp top the list, led by Bruges at Lden 55–75 dB (road traffic). The full ranking is in the table above.

How this ranking is measured
These are the same measurements behind the European ranking of all 314 cities — the EU Environmental Noise Directive strategic noise maps (road, rail, aircraft and industry), 2022 reporting round, harmonised by the European Environment Agency, with no estimation by us. Lden is the annual-average day-evening-night level; only residents above the 55 dB Lden threshold are reported, so the ranges describe the noise-exposed population.
