A recently published study from NIOSH examined hearing difficulty and tinnitus in various industries, based on data from the 2007 National Health Interview Survey. This provided detailed, self-reported information on hearing difficulty, tinnitus, and exposures to occupational noise. Some other findings are that:
-Seven percent of U.S. workers never exposed to noise on the job had hearing difficulty, 5 percent had tinnitus, and 2 percent had both conditions. Among workers who had at some point in their working careers been exposed to occupational noise, the prevalence was 23 percent, 15 percent, and 9 percent, respectively.
-Workers in agriculture, forestry, and the fishing and hunting industry had a significantly higher risk of hearing difficulty, tinnitus, and their co-occurrence. Manufacturing workers also had significantly higher risks for tinnitus and the co-occurrence of tinnitus and hearing difficulty.
-Workers in life, physical and social science occupations, and personal care and service occupations had significantly higher risks for hearing difficulty. Workers in architecture and engineering occupations also had significantly higher risks for tinnitus.
-Workers in sales and related occupations had significantly lower risks for hearing difficulty, tinnitus and their co-occurrence.
The study is the first to report prevalence estimates for tinnitus by U.S. industry sector and occupation and provide these estimates side by side with prevalence estimates of hearing difficulty, according to the agency. According to NIOSH, hazardous noise affects approximately 22 million U.S. workers.
