Of Bialystok's 296,401 residents, the noise-exposed share lives with average day-evening-night (Lden) transport noise of 45–65 dB, dropping to 40–55 dB overnight (Lnight). The dominant source is road traffic. Overall the city ranks #295 of 314 European cities, below the European median — quieter than most cities in the ranking. Among Poland's 36 ranked agglomerations, Bialystok is the 34th-loudest. Across Europe it sits just below Venice, Italy (#294) and just above Dabrowa Gornicza, Poland (#296).

The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, so Bialystok's exposed residents run roughly 2 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 Poland'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.
