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 who is qualied
by training and experience to assist in the evaluation and
rehabilitation of a child with hearing loss is recommended.
Cell phone
Some hearing aid users have reported a buzzing sound in their
hearing aids when they are using cell phones. According to the
ANSI C63.19 standard, the compatibility of a particular hearing
aid and cell phone can be predicted by adding the rating for the
hearing aid immunity to the rating for the cell phone emissions.
The sum of the hearing aid rating (e.g. M2/T2 = 2) and the
telephone rating (e.g. M3/T3 = 3) is 5, and any combination
that equals 5 will provide ‘normal use’. A sum of 6 or greater
indicates ‘excellent performance’. The equipment performance,
measurements, categories and system classications are based
upon the best information available but cannot guarantee that all
users will be satised.
The rating of this hearing aid is at least M2/T2. Your hearing
healthcare professional can provide the actual rating for this
hearing aid.
Note: The performance of the individual hearing aids may
vary with individual cell phones. Therefore, please try the
hearing aid with your cell phone or, if you are purchasing a
new phone, please be sure to try it with your hearing aid prior
to purchase. For additional guidance, please ask your hearing
healthcare professional for the booklet entitled “Hearing aid
compatibility with digital wireless cell phones.”
