Information for U.S. users from the Federal Drug Administration, Department of Health, Edu-
cation, and Welfare, Rules and Regulations for Medical Devices part 801- Hearing Aid Devices,
Professional and Patient Labeling and Conditions for Sale:
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 your hearing loss
has been medically evaluated and you may be considered a candidate for a hearing aid.
