Before Use

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 an audiologist or a hearing aid
dispenser, as appropriate, for a hearing aid evaluation.

The audiologist or hearing aid dispenser will conduct a
hearing aid evaluation to assess your ability to hear with
and without a hearing aid. The hearing aid evaluation
will enable the audiologist or dispenser to select and fit a
hearing aid to your individual needs.

If you have reservations about your ability to
adapt to amplification, you should inquire
about the availability of a trial-rental or
purchase-option program. Many hearing aid
dispensers now offer programs that permit
you to wear a hearing aid for a period of time
for a nominal fee after which you may decide
if you want to purchase the hearing aid.

Federal law restricts the sale of hearing aids
to those individuals who have obtained a
medical evaluation from a licensed physician.
Federal law permits a fully informed adult to
sign a waiver statement declining the medical
evaluation for religious or personal beliefs
that preclude consultation with a physician.
The exercise of such a waiver is not in your
best health interest and its use is strongly
discouraged.
