Czech Republic's 7 ranked cities are home to 2,951,313 residents. By exposed-resident Lden the field reads Plzen (50–70 dB), Prague (50–70 dB), Olomouc (50–70 dB), Ostrava (50–70 dB), Brno (50–70 dB), Liberec (50–70 dB), Teplice (50–70 dB), ending at Teplice (50–70 dB). The median lands near Lden 60 dB. Road traffic is the dominant source in all 7. The most populous, Prague at 1,442,378 residents, ranks #253 across Europe with exposed-resident Lden of 50–70 dB. The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, which most of these Czech Republic cities exceed for their noise-exposed residents.
The figures come straight from the country's END strategic noise maps and the EEA's harmonised 2022 dataset — day-evening-night (Lden) exposure for the noise-affected population only. 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 Czech Republic cities are the noisiest?
By this EEA data the noisiest Czech Republic cities are the same as the loudest, since "noisiest" here means measured road, rail, aircraft and industrial exposure: Plzen, Prague, Olomouc top the list, led by Plzen at Lden 50–70 dB (road traffic). The full ranking is in the table above.
Czech Republic noise: the numbers

- Loudest: Plzen at exposed-resident Lden 50–70 dB (European #249).
- Quietest ranked: Teplice at Lden 50–70 dB; median near Lden 60 dB.
- Road traffic is the dominant source in 7 of the 7.
- Combined population of the 7: 2,951,313.
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.
