Oct. 10, 2000 -- Do you have to ask people to repeat themselves when they are speaking to you? Does your family ever tell you that the TV or radio is too loud? If either answer is yes, odds are that you haven't spoken to your doctor about it, or if you have, the hearing aid that was suggested is still at the store. Now hear this: Hearing aids work, according to the first-ever major study of three popular types of hearing aids.

The study, which appears in the Oct. 11 issue of The Journal of the American Medical Association, found that three types of commonly used hearing aids improved speech recognition and reduced verbal communication problems in both quiet and noisy situations, when compared with no hearing aids at all.

As many as 28 million Americans -- including one-third of senior citizens -- have nerve-related hearing loss. This type of hearing loss occurs in either the sensory mechanism of the ear, called the cochlea, or in the nerve that sends the sound impulses to the brain.

This type of hearing loss can be helped by hearing aids. But only 20% of people who can benefit from hearing aids actually use them, for a variety of reasons including denial of the problem, cosmetic concerns, and/or the fact that many primary care doctors are not informed about the benefits of hearing aids.

"The take-home message is that hearing aids provide benefit and are effective in many different situations and they enhance communication," study author Lucille B. Beck, PhD, national director of audiology and speech pathology services for the Department of Veterans Affairs in Washington, D.C., tells WebMD.

"It provides scientific evidence for the medical community to encourage patients to seek help for their hearing problems," she says.

The study looked at 360 people with nerve-related hearing loss. All participants tested three types of hearing aids or circuits that differ in how they amplify sound -- the linear peak clipper, the compression limiter, and the wide dynamic range compressor -- in quiet and noisy conditions, then completed surveys about which hearing aid they liked best and why.
