[via: www.hear-it.org] Workers exposed to occupational noise have a five times higher risk of hearing problems and tinnitus, a study finds
A study from NIOSH (National Institute for Occupational Safety and Health) in the US has examined hearing difficulty and tinnitus in various industries.
The prevalence of hearing difficulty and tinnitus is nearly five times higher among workers exposed to occupational noise.
In the study NIOSH found that:
Among workers who had at some point in their working careers been exposed to occupational noise, 23% had hearing difficulty, 15% had tinnitus, and 9% had both conditions.
Among workers never exposed to noise on the job only 7% had hearing difficulty, 5% had tinnitus and 2% had both conditions.
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 a 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 of 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 of hearing difficulty, tinnitus and their co-occurrence.Read more
