36 | Regulatory Information
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.
A hearing aid will not restore normal hearing and will not prevent or improve a
hearing impairment resulting from organic conditions. Use of a hearing aid is
only part of hearing habilitation and may need to be supplemented by auditory
training and instruction in lip reading. In most cases infrequent use of a hearing
aid does not permit a user to attain full benefit from it. Special care should be
exercised in selecting and fitting a hearing aid whose maximum sound pressure
level exceeds 132 decibels because there may be risk in impairing the remaining
hearing of the hearing aid user.
Some hearing aid users have reported a buzzing sound in their hearing aid when
they are using mobile phones, indicating that the mobile phone and hearing aid
may not be compatible. According to the ANSI C63.19 standard (ANSI C63.19-
2007 American National Standard Methods of Measurement of Compatibility
Between Wireless Communications Devices and Hearing Aids), the compatibility
of a particular hearing aid and mobile phone can be predicted by adding the
rating for the hearing aid immunity to the rating for the mobile phone emissions.
For example, the sum of a hearing aid rating of 2 (M2/T2) and a telephone
rating of 3 (M3/T3) would result in a combined rating that equals at least 5
would provide “normal use”; a combined rating of 6 or greater would indicate
“excellent performance”. See the Product Card included with your hearing aids
for the exact M/T rating of your hearing aids.
CHILDREN WITH HEARING LOSS:
In addition to seeing a physician for a medical evaluation, a child with a hearing
loss should be directed to an audiologist for evaluation and rehabilitation since
hearing loss may cause problems in language development and the educational
and social growth of a child. An audiologist is qualified by training and experience
to assist in the evaluation and rehabilitation of a child with a hearing loss.
IMPORTANT NOTE:
Power BTE hearing aids are not intended for
patients under 36 months old.
