A study spanning a decade and incorporating hearing tests of more than 1.4 million American workers found that construction accounted for the second-highest prevalence of workers with a hearing impairment.

Conducted by the Centers for Disease Control and Prevention, the “Hearing Impairment Among Noise-Exposed Workers” study estimated the prevalence of hearing loss at six levels using hearing tests performed between 2003 and 2012. The study expressed the impact of hearing loss on quality of life as annual disability-adjusted life years (DALYs).
