Facts and Definitions

Scope of the Problem

  • In the United States, hearing loss is the third-most common chronic health condition among older adults after hypertension and arthritis.
  • Over 11% of the U.S. working population has hearing difficulty.
  • About 24% of the hearing difficulty among U.S. workers is caused by occupational exposures.

What causes Occupational Hearing Loss (OHL)?

  • OHL can occur when workers are exposed to loud noise or ototoxic chemicals.
  • Noise is considered loud (hazardous) when it reaches 85 decibels or higher, or if a person has to raise his/her voice to speak with someone 3 feet away (arm’s length).
  • Ototoxic chemicals (and examples) include:
  • organic solvents (styrene, trichloroethylene, mixtures)
  • heavy metals (mercury, lead, trimethyltin)
  • asphyxiants (carbon monoxide, hyrdrogen cyanide)

How Many Workers are Exposed?

  • About 22 million workers are exposed to hazardous noise each year.
  • About 10 million workers are exposed to solvents and an unknown number are exposed to other ototoxicants.

What is OHL Surveillance?

OHL surveillance includes:
  • Collecting worker hearing data, exposure data and related information for analysis;
  • Estimating how many workers have hearing loss or related health outcomes and how many workers are exposed;
  • Examining these estimates by industry and occupation; and
  • Monitoring trends over time.
The NIOSH OHL Surveillance Project commenced to establish a national repository for OHL data, and to conduct surveillance and research of this common occupational illness.
