Hearing loss with frequent diving (deaf divers).

Undersea Biomedical Research

|September 1, 1985

Summary

This summary is machine-generated.

Professional abalone divers often suffer from hearing loss due to repeated exposure to dysbaric conditions. Over 60% showed unacceptable high-frequency deafness, with over 70% having a compensatable hearing impairment.

Area of Science:

Occupational Health
Audiology
Diving Medicine

Background:

Professional abalone divers face significant occupational hazards.
Repeated exposure to dysbaric conditions is a known risk factor for various health issues.

Purpose of the Study:

To assess the prevalence of hearing loss in professional abalone divers.
To determine the extent of sensorineural hearing impairment in this cohort.

Main Methods:

An audiometric survey was conducted on professional abalone divers.
Hearing loss was evaluated against Australian standards and National Acoustic Laboratories criteria.

Main Results:

Over 60% of divers exhibited unacceptable sensorineural, high-frequency deafness.

Related Experiment Videos

Hearing loss was unilateral in 50% of affected divers and bilateral in the other 50%.

After age adjustment, over 70% had hearing loss deemed compensatable.

Conclusions:

Professional abalone diving is associated with a high incidence of sensorineural hearing loss.
Dysbaric exposure significantly impacts diver hearing, often requiring compensation.
