Washington, DC, November 29, 2011 — Nearly thirty million Americans—almost twice as many as previously believed—suffer from persistent, chronic tinnitus, according to a new study by the Better Hearing Institute (BHI). That’s about ten percent of the U.S. population. And for people ages 65 to 84, that number jumps to almost 27 percent. Notably, the study also found that many tinnitus sufferers reported that their hearing aids significantly helped them with their tinnitus.
For many who suffer from it, tinnitus can be a source of endless torment and a continual drain on quality-of-life. Often referred to as “ringing in the ears,” tinnitus is the perception of a sound that has no external source. Tinnitus sufferers commonly describe the noise as a ringing, humming, buzzing, and/or cricket-like. Tinnitus can be constant or intermittent. And it can be heard in one ear, both ears, or in the head.
According to the BHI study, four in ten people experience their tinnitus more than 80 percent of the time; slightly more than one in four describe their tinnitus as loud; and about one in five describe their tinnitus as disabling or nearly disabling. Tinnitus is now the number one service-connected disability of returning military personnel from Iraq and Afghanistan. There currently is no known cure for tinnitus.
“The good news is there are effective therapies available to help people cope,” said Sergei Kochkin, PhD, BHI’s Executive Director and co-author of the study. “In particular, we found that a variety of sound therapies and/or hearing aids in conjunction with counseling can help. In fact, 43.5 percent of survey respondents with tinnitus were helped at least mildly with hearing aids. And 3 out of 10 were helped moderately-to-substantially. For those whose audiologists used best practices in fitting hearing aids, that figure jumped to 50 percent.”
According to the study, people with tinnitus report that it most often affects their ability to hear (39%), concentrate (26%), and sleep (20%). Yet for many, tinnitus is even more pervasive. Twelve percent of respondents—or 3.6 million people when extrapolated to the general population—say their tinnitus affects leisure activities, social life, personal relationships, and emotional or mental health. Seven percent of respondents—or an estimated 2.1 million people nationwide—indicate that tinnitus affects their ability to work.
“Persistent, chronic tinnitus is a highly intrusive, increasingly common condition that can interfere with a person’s cognition, ability to interact with family and friends, and basic life functions,” said Jennifer Born, study co-author and Director of Public Affairs at the American Tinnitus Association (ATA). “Much progress is still needed in understanding tinnitus and finding a cure. But the results of this study are highly encouraging and prove that many tinnitus sufferers can experience relief and improved quality of life by using hearing aids in conjunction with counseling.”
Exposure to extreme noise is the leading cause of tinnitus, and people with tinnitus almost always have accompanying hearing loss, according to the study authors. In fact, the study found that respondents with more severe hearing loss were more likely to have tinnitus. Yet, more than a third (39%) of people with hearing loss do not seek help specifically because they have tinnitus.
“What surprised us was the large number of people—13 million—who reported tinnitus but no hearing loss,” said Kochkin. “It’s very likely that these individuals were aware of their tinnitus but not their hearing loss—which would indicate that the population with hearing loss is much larger than previously believed.”
As baby boomers age, people listen to portable music players at high volumes, and more soldiers return from combat, the incidence of both hearing loss and tinnitus is expected to grow.
“Unfortunately, relatively few people seek help for their tinnitus,” said Richard Tyler, PhD, study co-author, professor in both the Department of Otolaryngology-Head & Neck Surgery and the Department of Communication Sciences and Disorders at the University of Iowa in Iowa City, and editor of three books on tinnitus, including The Consumer Handbook on Tinnitus. “We need to raise awareness that effective therapies to help tinnitus sufferers are available. Many audiologists have attended a ‘tinnitus management’ seminar I organize each September, and I know there are many experienced tinnitus health professionals ready to help and offer a full evaluation. They can help identify treatment strategies most likely to offer relief. In particular, they will be able to determine if hearing aids can help.”
The study findings, were published in the November issue of Hearing Review. The findings were derived from a nationwide survey of 46,000 households. It is the largest study of its kind.
How Hearing Aids Help
In addition to improving hearing and communication, hearing aids amplify background sound, so the loudness or prominence of the tinnitus is reduced. Simply taking the focus off the tinnitus means relief for many people. Hearing aids also reduce the stress associated with intensive listening by improving communication, which in turn help relieve tinnitus symptoms.
Founded in 1973, BHI conducts research and engages in hearing health education with the goal of helping people with hearing loss benefit from proper treatment. For more information on hearing loss, visit www.betterhearing.org.
