Trends in hearing protector usage in American manufacturing from 1972 to 1989.
This study investigated the trends in hearing protector use in United States manufacturing industries. Using data from the National Institute for Occupational Safety and Health-sponsored National Occupational Hazard Survey (1972), the National Occupational Exposure Survey (1983), and the Occupational Safety and Health Administration-sponsored National Survey of Personal Protective Equipment Usage (1989), estimates were made of numbers of workers using hearing protection in various industries. Unique to this study is discussion of the impact of enactment of hearing conservation regulations during the same time frame as the two earlier surveys. In general, higher percentages of workers utilized hearing protection in 1989 than in 1972. Increased hearing protection use over time was also found when size of facility (number of employees) was taken into account. Differences in the use of hearing protection over the period 1972-1989 varied in individual industries, ranging from less than 10 to more than 30%.
