Hearing deterioration in professional divers: an epidemiologic study.

Summary

Professional divers experience significant hearing loss over time, with their hearing deteriorating faster than in non-divers. This decline is linked to occupational noise exposure and barotrauma, impacting hearing acuity.

Area of Science:

  • Audiology
  • Occupational Health
  • Diving Medicine

Background:

  • Professional divers face unique occupational hazards.
  • Hearing loss is a growing concern in various industries.
  • Previous studies suggest potential links between diving and hearing impairment.

Purpose of the Study:

  • To assess hearing acuity in professional divers.
  • To evaluate the longitudinal changes in hearing thresholds among divers.
  • To compare divers' hearing health with otologically normal and non-diver populations.

Main Methods:

  • Hearing acuity was measured in 116 professional divers.
  • Subjects were retested after approximately 6 years.
  • Hearing thresholds were compared across different age groups and with control populations.

Main Results:

  • Divers exhibited higher hearing thresholds than age-matched controls at both initial and final examinations.
  • Divers' hearing deteriorated significantly faster than that of otologically normal subjects.
  • Young divers initially had better hearing than unscreened non-divers, but this advantage diminished with age.

Conclusions:

  • Professional diving is associated with accelerated hearing deterioration.
  • Occupational noise exposure and barotrauma are significant contributing factors to hearing loss in divers.
  • Regular audiological monitoring is crucial for professional divers to detect and manage hearing impairment.
