Noise assessment among Alaska pipeline workers
Occupational Health & Safety (Waco, Tex.)
|November 1, 1981
Summary
Industrial jobs like pipefitting significantly increase hearing loss risk in workers over 25. Age also contributes to hearing deterioration across all job types studied.
Area of Science:
- Occupational Health
- Audiology
- Industrial Hygiene
Background:
- Noise-induced hearing loss is a significant occupational hazard.
- Understanding hearing thresholds in industrial settings is crucial for prevention.
- Previous studies provide baseline data for non-industrial populations.
Purpose of the Study:
- To assess hearing levels in Alaska pipeline workers.
- To identify specific industrial roles associated with hearing loss.
- To examine the impact of age on hearing thresholds in a working population.
Main Methods:
- Audiometric testing was conducted on 948 Alaska pipeline workers.
- Office employees' hearing data were used as controls.
- Hearing thresholds were analyzed across different job roles and age groups.
Main Results:
- Industrial workers over 25 showed significantly higher hearing loss.
- Pipefitters, carpenters, and mechanics were particularly affected.
- Hearing deterioration was observed in all employees with advancing age.
Conclusions:
- Certain industrial occupations pose a substantial risk for hearing loss.
- Age is a universal factor contributing to hearing decline in workers.
- Hearing conservation programs are essential for at-risk industrial workers.
