Noise and Occupational Hearing Loss
Overall Statistics – All U.S. Industries
Noise Exposure and Hearing Protection
- About 25% of all workers have been exposed to hazardous noise, with 14% (22 million) exposed in the last year.1
- 53% of noise-exposed workers report not wearing hearing protection.2
Hearing Loss and Tinnitus
- Approximately 12% of all workers have hearing difficulty.1
- About 8% of all workers have tinnitus.3
- About 16% of noise-exposed tested workers have a material hearing impairment.4 Hearing impairment is hearing loss that impacts day-to-day activities.
- 13% of noise-exposed tested workers have hearing impairment in both ears.5
Trends in Hearing Loss Among Noise-Exposed Tested Workers (1981-2010)6
- The prevalence for all industries combined decreased less than 1% over 30 years (1981-2010).
- The incidence for all industries combined decreased 2% over 25 years (1986-2010).
- The adjusted risk for all industries combined decreased 46% over 25 years (1986-2010).
