Traffic noise is a large-scale environmental exposure measured with several different acoustic indicators. The latest European Environment Agency assessment estimates road traffic exposure from 2022 mapping submissions, while health studies report associations, modelled burdens and attributable costs rather than identical clinical counts.
Key Traffic Noise Statistics
The most broadly useful figures cover exposure, sleep, cardiovascular outcomes, children and economic burden:
- In the latest END reporting round based on 2022 submissions, an estimated 92 million people in Europe were exposed to road traffic noise above 55 dB Lden.
- In 2022 noise mapping, about 67 million EU-27 urban residents were exposed to harmful road traffic noise.
- In 2022 noise mapping, nearly 69 million residents of the 32 EEA countries excluding Türkiye were exposed in urban areas.
- In the latest END reporting round, more than 20% of Europeans were exposed to harmful transport noise under END thresholds.
- Using stricter WHO recommendations, more than 30% of Europeans were exposed to transport noise in the latest assessment.
- In the latest EEA assessment, about 16.9 million Europeans experienced long-term annoyance from transport noise.
- In the same assessment, approximately 4.6 million Europeans experienced severe sleep disturbance from transport noise.
- Across studies in the updated WHO sleep review, each 10 dB increase in road Lnight was associated with OR 2.52 for highly sleep-disturbed respondents when the question named noise.
- A Northern European study published in 2020 found OR 3.54 for difficulty initiating sleep among 12,963 adults in seven centers exposed to traffic noise.
- A road-noise hypertension meta-analysis found OR 1.034 per 5 dB(A) increase in 16-hour road noise across road-noise-exposed populations.
- A later review through 2018 reported a 7% higher adult hypertension risk per 5 dB(A) chronic road-noise increase.
- The latest EEA assessment estimates more than 500,000 European children experience reading difficulties linked to transport noise.
- The same assessment estimates about 115,000 European children experience behavioral issues linked to transport noise.
- The latest EEA assessment estimates 73,000 premature deaths annually from transport noise in Europe.
- Transport noise is estimated to cause around 49,000 new cardiovascular disease cases annually in Europe.
- Transport noise is estimated to cost at least EUR 100 billion annually, or about 0.6% of regional GDP.
- The EU zero-pollution action plan sets a 30% reduction in chronic transport-noise disturbance by 2030 versus 2017 as a policy target.

Road Traffic Noise Exposure Statistics
The EEA’s latest assessment uses the most recent Environmental Noise Directive reporting round, based on 2022 submissions, with reported maps supplemented by gap-filling where data were missing. Its exposure estimates should therefore be read as modelled or mapped estimates, not a complete census of every person exposed.
| Measure | Population estimate | Scope and period |
|---|---|---|
| Road traffic above 55 dB Lden | 92 million people | Europe; latest END reporting from 2022 round |
| Road traffic in urban areas | 67 million people | EU-27; 2022 noise mapping |
| Road traffic in urban areas | Nearly 69 million people | EEA-32 excluding Türkiye; 2022 noise mapping |
| Rail traffic above the END threshold | 18 million people | Europe; latest END reporting from 2022 round |
| Aircraft noise above the END threshold | 2.6 million people | Europe; latest END reporting from 2022 round |
Source: Environmental noise in Europe 2025. Rail and aircraft figures are transport-source comparisons, not road traffic counts.
Most European countries have an estimated 30% to 60% of their urban population above 55 dB Lden from road traffic in the 2022 mapping. This is a reported country range, not a single pooled European percentage, and mapping coverage differs by country.
The WHO recommended road-traffic guideline is 53 dB Lden, below the END reporting threshold of 55 dB Lden. More than 20% of Europeans were exposed to harmful transport noise under END thresholds, rising above 30% when stricter WHO recommendations were used; both percentages include all transport noise rather than road traffic alone.
Road Traffic Noise Levels and Population Trends
Earlier assessments provide useful historical context but are not directly interchangeable with the latest numbers because the mapping round, geography and indicators differ. In the 2012 EEA-33 assessment, more than 100 million people were estimated above 55 dB Lden from road traffic, including about 32 million above 65 dB Lden.
The same earlier assessment estimated over 83 million Europeans above 50 dB Lnight from night-time road traffic in a 2012-era analysis. Lden and Lnight summarize exposure differently, so their threshold populations should not be compared as if they were the same measure.
A UK agglomeration example from 2017 strategic mapping shows how population counts decline as the night-time threshold rises:
| Road-traffic indicator and threshold | Estimated people | Period and geography |
|---|---|---|
| Lnight above 50 dB | 94,000 | 2017; UK agglomeration in table 43.3 |
| Lnight above 55 dB | 43,000 | 2017; same agglomeration |
| Lnight above 60 dB | 18,000 | 2017; same agglomeration |
| Lnight above 65 dB | 2,000 | 2017; same agglomeration |
| Lnight above 70 dB | Fewer than 500 | 2017; same agglomeration |
Source: Noise action plan: Agglomerations – appendix B. The estimates are rounded, and the final category is reported as an upper-bound category.
The same UK agglomeration was estimated to have 95,000 people above 55 dB LA10,18h, 48,000 above 60 dB, 32,000 above 65 dB, 17,000 above 70 dB and 3,000 above 75 dB in 2017 strategic mapping. LA10,18h is a different daytime indicator from Lden and Lnight, so these values are best used to show threshold bands within that table, not to rank indicators.
Between 2017 and 2022, the number of people highly annoyed by all transport noise fell by an estimated 3% in the EU. The EEA says this reduction is insufficient for the EU zero-pollution action plan target of a 30% reduction in chronic transport-noise disturbance by 2030 versus 2017, which is a policy target rather than an achieved result.
Traffic Noise Annoyance and Sleep Statistics
The latest EEA assessment estimates that about 16.9 million Europeans experience long-term annoyance and approximately 4.6 million experience severe sleep disturbance from transport noise. These totals include road, rail and aircraft sources, so they do not isolate road traffic.
The updated WHO sleep review examined exposure-response evidence from resident studies. It included 11 new studies with 109,070 responses, while the original WHO analysis contributed 25 studies and 64,090 responses to the update.
| Finding | Association | Measurement context |
|---|---|---|
| Highly sleep-disturbed, question named noise | OR 2.52 per 10 dB | Road Lnight; updated WHO review |
| Highly sleep-disturbed, question did not specify noise | OR 1.14 per 10 dB | Road Lnight; updated WHO review |
| Highly sleep-disturbed, question referred to noise | OR 2.13 per 10 dB | Original WHO review through 2015 |
| Highly sleep-disturbed, question did not refer to noise | OR 1.09 per 10 dB | Original WHO review through 2015 |
| Awakening | OR 1.36 per 10 dBA | Indoor road-noise Lmax; acute pooled estimate |
Sources: Environmental Noise and Effects on Sleep: An Update to the WHO Systematic Review and Meta-Analysis and Burden of disease from environmental noise. The updated estimates have 95% confidence intervals of 2.28–2.79 and 1.08–1.21 respectively; the original estimates have intervals of 1.82–2.48 and 0.94–1.27.
A 2020 survey of 12,963 adults in seven Northern European centers reported traffic-noise associations with difficulty initiating sleep at OR 3.54, difficulty maintaining sleep at OR 2.95 and early-morning awakening at OR 3.25. The study was cross-sectional and used self-reported exposure and outcomes, so these are associations rather than proof that traffic noise alone caused insomnia.
Traffic Noise and Cardiovascular Health Statistics
Road traffic noise has also been studied in relation to blood pressure and cardiovascular outcomes. The figures below are observational associations, and the exposure measures and populations differ.
A meta-analysis of studies published from 1970 to 2010 found OR 1.034 for hypertension per 5 dB(A) increase in 16-hour road noise. It covered 27 observational studies and aggregated 24 of them, with exposure ranging from 45 to 75 dB(A) LAeq16hr and a 95% confidence interval of 1.011–1.056.
A later review of 31 eligible studies, covering literature through 2018, reported a 7% higher adult hypertension risk per 5 dB(A) chronic road-noise increase. The authors noted high heterogeneity and methodological limitations, so the result should be interpreted cautiously.
| Outcome | Reported estimate | Comparison |
|---|---|---|
| Diabetes incidence | RR 1.07 | Per 5 dB road-noise increase |
| Angina | RR 1.23 | Highest versus lowest exposure |
| Myocardial infarction | RR 1.06 | Highest versus lowest exposure |
| Cardiovascular disease | RR 1.06 | Highest versus lowest exposure |
Source: Environmental noise exposure and health outcomes: an umbrella review. The reported 95% confidence intervals were 1.02–1.12 for diabetes, 0.80–1.89 for angina, 0.96–1.16 for myocardial infarction and 0.96–1.18 for cardiovascular disease; the latter three estimates were not statistically conclusive.
Across outcomes, every 10 dB road-noise increment was associated with a 2% to 8% increase in mortality or disease-incidence risk, but the umbrella review reported that these estimates were not statistically significant overall. The quantitative relationship between road traffic noise and hypertension and Epidemiological Studies on the Association between Chronic Exposure to Road Traffic Noise and Blood Pressure provide the hypertension evidence and its limitations.
Traffic Noise Effects on Children and Wider Health
The EEA models several effects across Europe, including effects attributed to transport noise rather than road traffic alone. Its latest assessment estimates that transport noise causes reading difficulties in more than 500,000 European children, behavioral issues in about 115,000 children, and approximately 223,000 cases of overweight children linked to high exposure.
These are modelled health-burden estimates, not counts from individual clinical records. They should be read alongside the source’s transport-wide scope and the uncertainty that accompanies attribution modelling.
The umbrella review reported RR 1.07 for diabetes incidence per 5 dB road-noise increase. For highest versus lowest road-noise exposure groups, it reported RR 1.23 for angina, RR 1.06 for myocardial infarction and RR 1.06 for cardiovascular disease; the confidence intervals for those three comparisons included the possibility of no statistically conclusive association.
The latest EEA assessment also estimates that transport noise contributes to 73,000 premature deaths annually in Europe, about 49,000 new cardiovascular disease cases annually and 23,000 type 2 diabetes cases annually. These are annual modelled attributable burdens for all transport noise, not road-traffic-only clinical tallies.
Traffic Noise Costs, Burden and Policy Targets
The EEA estimates that transport noise costs at least EUR 100 billion annually, equivalent to about 0.6% of regional GDP. Its burden-of-disease model estimates 1.5 million healthy life-years are lost annually from transport noise in Europe.
| Burden measure | Estimate | Scope and period |
|---|---|---|
| Premature deaths | 73,000 annually | Europe; all transport noise |
| New cardiovascular disease cases | 49,000 annually | Europe; all transport noise |
| Type 2 diabetes cases | 23,000 annually | Europe; all transport noise |
| Economic cost | At least EUR 100 billion annually | Europe; all transport noise |
| Healthy life-years lost | 1.5 million annually | Europe; all transport noise |

The WHO’s burden assessment, published in 2011, estimated 903,000 DALYs from sleep disturbance, 587,000 DALYs from annoyance, 61,000 DALYs from ischaemic heart disease, 45,000 DALYs from cognitive impairment in children and 22,000 DALYs from tinnitus. These estimates cover EU Member States and other western European countries, are mostly road-related but environmental-noise totals, and use conservative assumptions.
WHO’s estimates exclude parts of south-eastern Europe and the newly independent states because exposure data were unavailable. The EEA and WHO totals also come from different periods, geographies, definitions and modelling approaches, so they should not be added together or treated as a time series.
