OCCUPATIONAL HEARING LOSS (OHL) SURVEILLANCE

Transportation, Warehousing and Utilities (TWU) Statistics

Noise Exposure and Hearing Protection

  • About 40% of all workers in Transportation and Warehousing and 43% of all workers in Utilities have been exposed to hazardous noise.1
  • 33% of noise-exposed Transportation and Warehousing workers and 20% of noise-exposed Utilities workers report not wearing hearing protection.2

Hearing Loss and Tinnitus

  • Approximately 13% of all Transportation and Warehousing workers and 27% of all Utilities workers have hearing difficulty.1
  • About 7% of all Transportation and Warehousing workers and 12% of all Utilities workers have tinnitus.3
  • About 12% of noise-exposed tested TWU workers have a material hearing impairment.4 Hearing impairment is hearing loss that impacts day-to-day activities.
  • 8% of noise-exposed tested TWU workers have hearing impairment in both ears.5

Trends Among Noise-Exposed Tested TWU Workers (1981-2010)4

  • The prevalence for TWU decreased 6% over 30 years (1981-2010) as compared with a less than 1% reduction for all industries.
  • The incidence for TWU decreased 4% over 25 years (1986-2010) as compared with a 2% reduction for all industries.
  • The adjusted risk for TWU decreased 52% over 25 years (1986-2010) as compared with a 46% reduction for all industries.
