Noise pollution is measured both as sound exposure and as its effects on people. The available evidence below combines survey findings, WHO guidance, modeled European estimates, U.S. audiometry and forward-looking scenarios, with periods and limitations kept explicit.
Key Noise Pollution Statistics
Noise pollution data highlights include:
- In 2016–2017, 32% of more than 30,000 European survey participants reported noise problems in their immediate neighbourhood.
- In 2018 WHO guidance, average road-traffic noise is recommended below 53 dB Lden in the WHO European Region.
- In the 2022 reporting round, about 112 million people in Europe were exposed to long-term transport noise above END thresholds.
- When stricter WHO recommendations were applied to the same European reporting context, about 150 million people faced long-term unhealthy transport-noise levels.
- In the 2022 European reporting round, road transport exposed about 92 million people above the 55 dB Lden END threshold.
- In a 2021 European assessment published in 2025, transport noise was estimated to contribute to 73,000 premature deaths.
- The same assessment estimated 49,000 new cardiovascular-disease cases in Europe were linked to transport noise.
- In the 2021 assessment, almost 16.9 million Europeans were estimated to experience long-term high annoyance from transport noise.
- Transport noise was estimated to cause 1.5 million lost healthy life years annually in Europe in the 2021 assessment.
- The annual economic cost associated with European transport-noise pollution was estimated at at least EUR 100 billion, or around 0.6% of regional GDP.
- In 2022, more than 20 million people in the EU-27 were estimated to be highly annoyed by road, rail or aircraft noise.
- In 2022, almost 7 million people in the EU-27 were estimated to be highly sleep disturbed by transport noise.
- In 2011–2012, 24.4% of U.S. adults aged 20–69 had audiometric notches suggestive of noise-induced hearing loss, representing 39.4 million people.
- In 2011–2012, 70% of U.S. adults exposed to loud noise seldom or never wore hearing protection.
- In 2018, NIOSH estimated 22 million U.S. workers were exposed to hazardous workplace noise levels.
- In 2022, more than 1 billion people aged 12–35 worldwide were estimated to be at risk of hearing loss from recreational sound exposure.
- The EU zero-pollution action plan targets a 30% reduction by 2030 in people chronically disturbed by transport noise compared with 2017.

How Noise Pollution Is Measured Across Major Sound Sources
Noise pollution statistics use different measures for perception, long-term exposure, nighttime disturbance and short-term sound. A survey response is not interchangeable with a decibel observation, and a guideline is a benchmark rather than a population average.
The 2016–2017 European Quality of Life survey found that 32% of more than 30,000 participants reported noise problems in their home’s immediate neighbourhood. This was a self-reported perception measure, not a direct sound-level measurement. Compendium of WHO and other UN guidance on health and environment
| Sound source or exposure | WHO recommended level | Period and scope |
|---|---|---|
| Road traffic, average | Below 53 dB Lden | 2018 guideline, WHO European Region |
| Railway, average | Below 54 dB Lden | 2018 guideline, WHO European Region |
| Aircraft, average | Below 45 dB Lden | 2018 guideline, WHO European Region |
| Wind turbines, average | Below 45 dB Lden | Conditional recommendation, 2018 guideline |
| Leisure noise, yearly average | No more than 70 dB LAeq,24h | 2018 guideline |
| Leisure noise, weekly average | No more than 80 dB(A), or 1.6 Pa2h | 2018 guideline |
| Leisure noise, occasional 15-minute exposure | No more than 100 dB LAeq,15min | 2018 guideline |
| Road traffic at night | Below 45 dB Lnight | 2018 guideline |
| Railway at night | Below 44 dB Lnight | 2018 guideline |
These WHO values are guidance benchmarks summarized in 2022, not observed averages for the population. The units also reflect different time windows, so they should not be read as one single universal noise limit. Compendium of WHO and other UN guidance on health and environment
Transport Noise Exposure Statistics in Europe
European exposure estimates focus most strongly on transport sources reported through Environmental Noise Directive mapping. The 2022 reporting round, published in 2025, estimated that about 112 million people experienced long-term road, rail or aircraft noise above END thresholds.
Applying stricter WHO recommendations increased the estimated affected population to about 150 million people. Both figures are modeled estimates based on reported noise maps and exposure-response relationships, not a direct census. Environmental noise in Europe 2025 – summary for policymakers
The transport-source breakdown shows how road noise dominates the reported exposure totals:
- Road transport exposed about 92 million people above the 55 dB day-evening-night END threshold in the 2022 reporting round.
- Road transport exposed about 58 million people above the END nighttime threshold.
- Railway noise affected about 18 million people during the day-evening-night period above END thresholds.
- Railway noise affected about 13 million people at night above END thresholds.
- Aircraft noise affected about 2.6 million people during the day-evening-night period above END thresholds.
- Fewer than 1 million people were exposed to aircraft noise at night above END thresholds; this is an upper-bound category rather than an exact count.
The EEA notes that coverage is strongest for reported transport sources and does not cover every noise source or location. These estimates should therefore be read as a mapped transport-noise picture, not a complete global inventory. Environmental noise in Europe 2025 – summary for policymakers
Noise Pollution Health and Economic Outcomes
The EEA’s 2021 assessment, published in 2025, estimated that long-term transport-noise exposure contributed to substantial health burdens across Europe. The online summary states that the health-outcome estimates were corrected in March 2026; the figures below follow that corrected summary.
| Estimated outcome | European estimate | Assessment period |
|---|---|---|
| Premature deaths | 73,000 | 2021 assessment, published 2025 |
| New cardiovascular-disease cases | 49,000 | 2021 assessment, published 2025 |
| New type 2 diabetes cases | 23,000 | 2021 assessment, published 2025 |
| High annoyance | Almost 16.9 million people | 2021 assessment, published 2025 |
| Severe sleep disturbance | Approximately 4.6 million people | 2021 assessment, published 2025 |
| Children with reading difficulties | Over 560,000 | 2021 assessment, published 2025 |
| Children with behavioral issues | About 116,000 | 2021 assessment, published 2025 |
| Children with overweight | About 224,000 | 2021 assessment, published 2025 |
| Healthy life years lost | 1.5 million annually | 2021 assessment, published 2025 |
The estimate for children with overweight is an association estimate, not proof of individual causation. The other health figures are modeled estimates using reported noise maps and exposure-response relationships. Environmental noise in Europe 2025 – summary for policymakers
The associated annual economic cost was estimated at at least EUR 100 billion, equivalent to around 0.6% of regional GDP. This is a minimum regional estimate, and valuation methods affect the total. Environmental noise in Europe 2025 – summary for policymakers
For the EU-27 specifically, the 2022 modeled indicators estimated more than 20 million people highly annoyed and almost 7 million highly sleep disturbed by road, rail or aircraft noise. Health impacts of exposure to noise from transport in Europe
Hearing-Loss and High-Noise Exposure Statistics
U.S. audiometry provides a different view of noise-related harm from the European transport models. NHANES data for 2011–2012 estimated audiometric notches suggestive of noise-induced hearing loss in 24.4% of U.S. adults aged 20–69, representing 39.4 million people.
Among this U.S. age group, 6.2% had bilateral notches and 18.2% had unilateral notches. Prevalence rose from 19.2% among adults aged 20–29 to 27.3% among those aged 50–59. Vital Signs: Noise-Induced Hearing Loss Among Adults – United States 2011–2012
Several findings show why self-assessment and exposure history do not tell the whole story:
- About 21 million U.S. adults reporting no loud workplace-noise exposure still had an audiometric notch, and the prevalence in that subgroup was 19.9%.
- U.S. adults reporting workplace loud-noise exposure were 2 times as likely to have an audiometric notch as those not reporting it.
- Among adults rating their hearing excellent or good, 23.5% still had a bilateral or unilateral audiometric notch.
- Audiometric notches affected 31.0% of adults reporting workplace noise exposure versus 20.1% without reported workplace exposure.
- 70% of U.S. adults exposed to loud noise in the previous 12 months seldom or never wore hearing protection.
These are cross-sectional NHANES estimates. An audiometric notch suggests noise-related damage but does not prove individual causation. Vital Signs: Noise-Induced Hearing Loss Among Adults – United States 2011–2012
Workplace surveillance adds scale: NIOSH estimated 22 million U.S. workers were exposed to hazardous workplace noise levels in its 2018 CDC summary, while estimated hearing-loss prevalence among noise-exposed workers ranged from 12% to 25%, depending on industry. These are older estimates and are not 2026 counts. CDC Grand Rounds: Promoting Hearing Health Across the Lifespan
Globally, WHO estimated in 2022 that more than 1 billion people aged 12–35 were at risk of hearing loss from prolonged or excessive recreational sound exposure. WHO’s safe-listening venue standard sets a maximum average sound level of 100 dB for amplified-music venues and events; this is a recommended standard, not a compliance survey. WHO releases new standard to tackle rising threat of hearing loss
Noise Pollution Trends and the 2030 Policy Outlook
The EU zero-pollution action plan targets a 30% reduction by 2030 in people chronically disturbed by transport noise compared with the 2017 baseline. Progress reported so far is modest: the EEA estimated that people highly annoyed by transport noise declined by about 3% between 2017 and 2022. Environmental noise in Europe 2025 – summary for policymakers
For the EU-27, the modeled population highly annoyed declined only 3.5% between 2017 and 2022, while the population highly sleep disturbed declined by less than 1%. Reaching the 2030 target would require a further reduction of 5.6 million highly annoyed people and 2 million highly sleep disturbed people from the 2022 estimates. Health impacts of exposure to noise from transport in Europe
Scenario projections show why the policy outlook remains uncertain:
| EEA scenario | People above 55 dB Lden by 2030 | Highly annoyed people by 2030 |
|---|---|---|
| Optimistic scenario | 18% below the estimated 2017 baseline | 21% below the 2017 baseline |
| Conservative scenario | 2% above the estimated 2017 baseline | 0% reduction from the 2017 baseline |
These are modeled scenarios rather than direct counts. The projections cover the European area included by the EEA scenario and should not be treated as a universal forecast. Transport noise | Sustainability of Europe’s mobility systems 2025
Noise exposure also has an environmental dimension. In the 2022 assessment published in 2025, transport noise affected 29% of Natura 2000 area at levels potentially harmful to terrestrial wildlife; this is modeled potential exposure, not a direct wildlife-health diagnosis.
Only 34% of the population in 233 assessed European cities could access green and quiet areas within a 400-metre walk of home. Environmental noise in Europe 2025 – summary for policymakers
