Noise, ototoxic chemicals, and hearing protection

  • About 28% of all workers have been exposed to hazardous noise, with 16% (27 million) exposed in the last year.1
  • Approximately 13% of all workers (22 million) have been exposed to ototoxic chemicals in the last year.1These chemicals can cause damage to different parts of the ear.
  • About 7% of all workers have been exposed to both hazardous noise and ototoxic chemicals in the last year.1
  • 53% of noise-exposed workers report not wearing hearing protection.2

Hearing loss and tinnitus

  • Approximately 11% of all workers have hearing difficulty.1
  • About 8% of all workers have tinnitus, which is an annoying buzzing, rushing, or ringing noise in your ears or in your head.3
  • About 20% of noise-exposed tested workers have a material hearing impairment.4 Hearing impairment is hearing loss that impacts day-to-day activities. Material hearing impairment is hearing loss severe enough that a person has difficulty understanding speech.
  • 13% of noise-exposed tested workers have hearing impairment in both ears.5

Trends in hearing loss

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).
