OCCUPATIONAL HEARING LOSS (OHL) SURVEILLANCE

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
  • 34% 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 19% 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)4

  • 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).
