Important Notice for Prospective Hearing Aid Users
Good health practice requires that a person with a hearing loss have a medical evaluation by a licensed
physician (preferably a physician who specializes in diseases of the ear) before purchasing a hearing aid.
Licensed physicians who specialize in diseases of the ear are often referred to as otolaryngologists,
otologists, or otorhinolaryngologists. The purpose of medical evaluation is to assure that all medically
treatable conditions that may affect hearing are identified and treated before the hearing aid is
purchased.
Following the medical evaluation, the physician will give you a written statement that states that your
hearing loss has been medically evaluated and that you may be considered a candidate for a hearing
aid. The physician will refer you to an audiologist or a hearing care professional, as appropriate, for a
hearing aid evaluation.
The audiologist or hearing care professional will conduct a hearing aid evaluation to assess your degree
of hearing.
