Trends in hearing protector usage in American manufacturing from 1972 to 1989

Area of Science:

• Occupational Health
• Industrial Hygiene
• Public Health Policy

Background:

• Hearing loss is a significant occupational hazard in manufacturing industries.
• The effectiveness of hearing conservation programs is influenced by worker compliance with hearing protector usage.
• Regulatory changes play a crucial role in shaping workplace safety practices.

Purpose of the Study:

• To analyze trends in hearing protector utilization among US manufacturing workers between 1972 and 1989.
• To assess the impact of hearing conservation regulations on the adoption of hearing protection devices.
• To examine variations in hearing protection use across different industries and facility sizes.

Main Methods:

• Utilized data from three national surveys: National Occupational Hazard Survey (1972), National Occupational Exposure Survey (1983), and National Survey of Personal Protective Equipment Usage (1989).
• Estimated the number of workers using hearing protection across various manufacturing sectors.
• Correlated hearing protector usage trends with the timeline of enacted hearing conservation regulations.

Main Results:

• A general increase in the percentage of workers using hearing protection was observed from 1972 to 1989.
• Hearing protector use increased over time, even when accounting for facility size (number of employees).
• Industry-specific differences in hearing protection use varied significantly, with changes ranging from under 10% to over 30%.

Conclusions:

• Hearing protector use in US manufacturing industries has shown a positive upward trend.
• The implementation of hearing conservation regulations likely contributed to increased hearing protection adoption.
• Continued monitoring and enforcement are essential to further improve occupational hearing safety.
