Workers with tinnitus and hearing loss have a 25% greater risk to be injured at work, study finds.
Workers with a history of tinnitus (ringing in the ear) togehter with a high-frequency hearing loss are more likely to be injured, according to a study from Yale University in the US.
The researchers analyzed more than 9,900 production and maintenance workers who were employed at six aluminum manufacturing plants from 2003 to 2008. Researchers adjusted for ambient noise exposure as part of the project.
The risk of acute injury was 25 percent greater among workers with tinnitus and high-frequency hearing loss. Workers with tinnitus and low-frequency hearing loss did not face the same risk of acute injury but were more likely to sustain minor injuries.
Hearing tests and ear protection
At-risk workers in noisy work environments might require an additional examination of their hearing and hearing protection needs, the researchers said.
The study was published in the International Journal of Audiology.
