Hearing devices significantly improve social lives of those with hearing loss: Study

Hearing loss doesn't just affect how people hear the world-it can also change how they connect with it.

A new study from the USC Caruso Department of Otolaryngology – Head and Neck Surgery, part of Keck Medicine of USC, published today in JAMA Otolaryngology – Head & Neck Surgery, is the first to link hearing aids and cochlear implants, surgically implanted devices that help those with profound hearing loss perceive sound, to improved social lives among adults with hearing loss.

“We found that adults with hearing loss who used hearing aids or cochlear implants were more socially engaged and felt less isolated compared to those who didn’t use them,” said Janet Choi, MD, MPH, an otolaryngologist with Keck Medicine and lead researcher of the study. “This suggests that hearing devices may help prevent the social disconnection and broader health consequences that can follow untreated hearing loss.”

Hearing loss affects an estimated 40 million American adults, yet many go untreated. When left unaddressed, hearing loss can make communication difficult, leading people to withdraw from conversations and social activities, according to Choi.

Previous research has shown that over time, social withdrawal can reduce mental stimulation and increase the risk of loneliness, anxiety, depression, cognitive decline and dementia. It has also linked chronic social isolation to biological and neurological changes, including increased brain inflammation and alterations in brain structure.

“Understanding the link between hearing loss, hearing device use and social isolation is crucial,” said Choi. “Until this study, it has been unclear whether hearing devices could help reverse the isolation.”

Choi and her fellow researchers conducted a comprehensive, systematic review and meta-analysis of 65 previously published studies, encompassing over five thousand participants, on how hearing aids and cochlear implants affect three key measures: social quality of life, perceived social handicap, which refers to the limitations and frustrations hearing loss can create in social situations, and loneliness.

The researchers found that adults using hearing devices feel more socially connected and less limited in social situations. They are better able to engage in group conversations and feel more at ease in noisy or challenging listening environments. Participants also reported feeling less socially handicapped by their hearing loss, with fewer barriers and frustrations during interactions and an improved ability to stay engaged without feeling excluded. This increased confidence can help users connect more easily with family, friends and colleagues, leading to stronger feelings of belonging and reduced social anxiety. The study also suggested hearing devices may reduce loneliness, although further research is needed in this area, according to Choi.

Those with cochlear implants reported the most improvement in their social quality of life. This is likely because cochlear implants offer greater hearing restoration than hearing aids, especially for individuals with more severe hearing loss. As a result, they may experience more noticeable improvements in social engagement once their hearing is restored.

While it was outside the scope of the study to measure how better social lives relate to improved cognitive outcomes, Choi believes there may be a connection, as previous research has found managing hearing loss may be key to reducing the risk of cognitive decline and dementia. “While our study didn’t directly measure cognitive outcomes, the improvements we saw in communication and social engagement suggest that by restoring clearer communication, hearing devices may help preserve cognitive health by keeping the brain more actively involved and people more connected,” Choi said.

This research follows a January 2024 study by Choi showing that adults with hearing loss who use hearing aids have an almost 25% lower risk of mortality, suggesting that treating hearing loss can improve lifespan as well as social quality of life.

“These new findings add to a growing body of research showing that hearing health is deeply connected to overall well-being,” said Choi. “We hope this encourages more people to seek treatment and helps clinicians start conversations with patients about how hearing devices can improve their quality of life.”
