Significantly dropping the cost of hearing aids doesn't motivate people with mild hearing loss to get one. A new study finds lowering the price by as much as 40% doesn't make a difference. Researchers at Detroit's Henry Ford Hospital say the only patients who will get a hearing aid at a younger age are those with significant hearing loss and full insurance coverage, defying the common assumption that it is price that prevents most people from purchasing a hearing aid. Details of the study are published in The Hearing Journal.
