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 aect hearing are identied and treated before
thehearing 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 aid dispenser,
as appropriate, for a hearing aid evaluation.
