Romania's 6 ranked cities are home to 3,145,635 residents. By exposed-resident Lden the field reads Bacau (55–75 dB), Iasi (55–75 dB), Bucharest (55–70 dB), Satu Mare (55–70 dB), Timisoara (55–70 dB), Craiova (55–70 dB), ending at Craiova (55–70 dB). The median lands near Lden 62.5 dB. Road traffic is the dominant source in all 6. The most populous, Bucharest at 2,161,347 residents, ranks #41 across Europe with exposed-resident Lden of 55–70 dB. The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, which most of these Romania 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 Romania cities are the noisiest?
By this EEA data the noisiest Romania cities are the same as the loudest, since "noisiest" here means measured road, rail, aircraft and industrial exposure: Bacau, Iasi, Bucharest top the list, led by Bacau at Lden 55–75 dB (road traffic). The full ranking is in the table above.
Romania noise: the numbers
- 6 Romania agglomerations are in the measured European ranking — 13th-most of any country here.
- Loudest: Bacau at exposed-resident Lden 55–75 dB (European #2).
- Quietest ranked: Craiova at Lden 55–70 dB; median near Lden 62.5 dB.
- Road traffic is the dominant source in 6 of the 6.
- Combined population of the 6: 3,145,635.
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.
