Some OTC Hearing Assistance Devices Pretty Much Match the Performance of a More Expensive Conventional Hearing Aid

A comparison between less expensive, over-the-counter hearing assistance devices and a conventional hearing aid found that some of these devices were associated with improvements in hearing similar to the hearing aid, according to a Johns Hopkins study published in July 2017 by JAMA.

A release from the publisher notes that currently, hearing aids can only be purchased in the United States through a licensed professional, with an average cost of $4,700 for two hearing aids (uncovered by Medicare). According to nationally representative estimates, fewer than 20 percent of adults with hearing loss report hearing aid use. Personal sound amplification products (PSAPs) are less-expensive, over-the-counter devices not specifically labeled for hearing loss treatment, but some are technologically comparable with hearing aids and may be appropriate for mild to moderate hearing loss.

Nicholas S. Reed, Au.D., of the Johns Hopkins School of Medicine, Baltimore, and colleagues compared five of these devices (costs, approximately $350 to $30) with a conventional hearing aid (cost, $1,910) among 42 adults (average age, 72 years) with mild to moderate hearing loss.

The researchers found that the change in accuracy in speech understanding from unaided to aided varied by device. Three of the PSAPs were associated with improvements in speech understanding that were similar to results obtained with the hearing aid; one demonstrated little improvement; and speech understanding was worse with one PSAP.

“Results lend support to current national initiatives from the National Academies, White House, and bipartisan legislation requesting that the U.S. Food and Drug Administration create a new regulatory classification for hearing devices meeting appropriate specifications to be available over the counter,” the authors write.

A limitation of the study was the modest number of participants.
