Having poor hearing doesn’t just put you at a social disadvantage. It may put you in harm’s way, too, increasing your risk of getting injured in a variety of situations, including at work.
That's the news from a study in a March 2018 issue of JAMA Otolaryngology-Head & Neck Surgery, which examined how hearing ability played a role for the 6.6 million U.S. adults who experienced accidental injuries annually between 2007 and 2015. It turns out that those who reported having “a little trouble” hearing were 60 percent more likely to have been injured, those with “moderate trouble” were 70 percent more likely, and those with “a lot of trouble” hearing were 90 percent more likely to have been injured, compared with those with normal hearing.
The close relationship between the degree of self-reported hearing loss and the increased risk of accidents was noteworthy, says study author Neil Bhattacharyya, a professor of otolaryngology at Harvard Medical School. The correlation was especially strong with accidental injuries suffered at work or while participating in leisure or sport-related activities.
It makes sense, says Bhattacharyya: If you can't hear well, you lose that crucial warning system that would signal to you that a car or truck is driving up behind you while you’re biking, for example. “As a special sense, hearing has a tremendous protective role,” he says.
The fact that work-related injuries were also higher among participants in the study may be a bit more surprising. “Numerous studies have demonstrated that hearing loss and working in very noisy environments both contribute to the incidence of work-related injuries,” says Sarah Sydlowski, audiology director of the Hearing Implant Program at the Cleveland Clinic. But even in quieter workplaces, people with compromised hearing may not hear crucial directions, warnings, alerts or other communications. And if they have asymmetric hearing between their ears, they may not be able to tell where the sound is coming from (a problem with spatial orientation).
