The loudest cities in Croatia, ranked by noise exposure
Among Croatia's 3 ranked agglomerations, Rijeka is the noisiest: its exposed population lives with Lden 55–75 dB of day-evening-night transport noise, #19 of all European cities measured. The typical Croatia city in the list centres near Lden 65 dB.

| Croatia # | City | Europe # | Lden | Lnight | Source | Population |
|---|---|---|---|---|---|---|
| 1 | Rijeka | 19 | 55–75 | 50–65 | Road | 107,964 |
| 2 | Zagreb | 25 | 55–75 | 50–65 | Road | 767,131 |
| 3 | Split | 26 | 55–70 | 50–65 | Road | 160,577 |
Across Croatia, 3 cities make the measured European ranking — 1,035,672 people combined. In order of Lden exposure: Rijeka (55–75 dB), Zagreb (55–75 dB), Split (55–70 dB), down to Split (55–70 dB). The midpoint sits near Lden 65 dB. Road traffic is the dominant source in all 3. The most populous, Zagreb at 767,131 residents, ranks #25 across Europe with exposed-resident Lden of 55–75 dB. The WHO road-traffic guideline is 53 dB Lden by day and 45 dB Lnight at night, which most of these Croatia cities exceed for their noise-exposed residents.
Every range is reported exposure: the EEA's 2022 END dataset, counting people above the 55 dB Lden threshold from road, rail, aircraft and industrial sources — nothing modelled by us. 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 Croatia cities are the noisiest?
By this EEA data the noisiest Croatia cities are the same as the loudest, since "noisiest" here means measured road, rail, aircraft and industrial exposure: Rijeka, Zagreb, Split top the list, led by Rijeka at Lden 55–75 dB (road traffic). The full ranking is in the table above.
Croatia noise: the numbers
- 3 Croatia agglomerations are in the measured European ranking — 18th-most of any country here.
- Loudest: Rijeka at exposed-resident Lden 55–75 dB (European #19).
- Quietest ranked: Split at Lden 55–70 dB; median near Lden 65 dB.
- Road traffic is the dominant source in 3 of the 3.
- Combined population of the 3: 1,035,672.
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.
