Behind-the-ear hearing aids, in-the-ear hearing aids, completely in the canal hearing aids, binaural hearing aids...and the list goes on. With so many types and hundreds of brands to choose from, what is a senior to do? First and foremost, don’t go it alone. Too often, seniors are wooed by a catchy ad or a pushy salesman and wind up with an expensive hearing aid that they shove in a drawer and never use. Work with a qualified audiologist who can conduct a thorough hearing evaluation, determine the type and degree of hearing loss and recommend the appropriate hearing aid, says Dr. Phillip L. Wilson, Au.D., Head of Audiology at Callier Center for Communication Disorders, University of Texas at Dallas.
