The fraction of deaf or hard-of-hearing people who are equipped with some form of hearing assistance is surprisingly low. According to the Hearing Loss Association of America (HLAA), only about 1 in 5 people who would benefit from a hearing aid uses one, and on average people with hearing loss wait 7 years before seeking treatment. Many providers of hearing loss products and services need help measuring the size of their potential market. HearingMarketResearch intends to provide that help.
