Background: This study estimated the prevalence of hearing protection device (HPD) non-use and provided risk estimates among U.S. workers exposed to hazardous workplace noise. Methods: Self-reported data from the National Health Interview Survey in 2007 (15,852 workers) and 2014 (23,656 workers) were examined. Weighted prevalence and adjusted prevalence ratios of HPD non-use were estimated by demographic, industry and occupation. Differences in the prevalences of non-use were estimated and compared. Results: The prevalence of HPD non-use was 53% among all noise-exposed workers in 2014. Workers in the Accommodation and Food Services industry had the highest prevalence (90%) and risk of HPD non-use. Industries with the lowest prevalences of noise exposure had some of the highest prevalences of HPD non-use. There were no statistically significant changes in HPD non-use among industries between 2007 and 2014. Among occupations, HPD non-use increased 37% in Arts, Design, Entertainment, Sports and Media, and decreased 39% in Architecture and Engineering. Conclusion: The prevalence of HPD non-use remains high; especially within industries and occupations with fewer noise-exposed workers. These groups need targeted attention. Employers should require HPD use, and provide trainings, and HPDs tailored to noise level and type, workplace environment, and individual comfort and convenience.
