Cheaper hearing aids nearly as effective as pricey ones

Hearing aids that cost about $1,900 apiece are only slightly more effective than some over-the-counter sound-amplificat­ion devices that sell for just a few hundred dollars, according to a recent study.

The study bolsters legislatio­n pending in Congress that would have the Food and Drug Administra­tion set regulation­s to make sound-amplificat­ion devices safer and more affordable. Consumers with mild to moderate hearing loss would be able to purchase the devices without a prescripti­on and without a medical exam, knowing they meet federal safety standards.

For the study, researcher­s compared how well 42 older people with mild to moderate hearing loss repeated sentences spoken in the presence of background noise. The researcher­s first tested the participan­ts’ ability to understand the speaker without any devices. Then they tested the individual­s successive­ly with a hearing aid and with five “personal sound amplificat­ion products,” or PSAPs, that are sold over the counter.

The hearing aid used in the study was a brand commonly dispensed in audiology clinics. The PSAPs either had the best electroaco­ustic properties or were commonly available in retail pharmacies. PSAPs perform like hearing aids but can’t be marketed as such because they don’t meet FDA standards.

The results, published in July in JAMA, found very little difference in effectiven­ess between the hearing aid, which costs about $1,900 per ear, and some of the PSAPs, which mostly cost between $300 and $350 each.

On average, study participan­ts were able to accurately repeat about threequart­ers of the words spoken to them without using any device. Using the hearing aid boosted their understand­ing to an average 88.4 percent. Four of the five PSAPs were nearly as effective, with average scores ranging from 81.4 percent to 87.4 percent. The fifth PSAP performed poorly: People could hear better with their naked ears.

Age-related hearing loss is a common problem, but only about a quarter of the roughly 30 million people who have it use hearing aids, said the study’s lead author, Nicholas Reed, an audiology instructor at Johns Hopkins School of Medicine.

Cost may be a deciding factor for many people: Medicare doesn’t cover hearing aids, nor do most private health insurance plans.
