than others to this interference noise, and phones also vary in the
amount of interference they generate.
The wireless telephone industry has developed ratings for some of
their mobile phones, to assist hearing device users in finding phones
that may be compatible with their hearing devices. Not all phones have
been rated. Phones that are rated have the rating on their box or a
label on the box. To maintain the published Hearing Aid Compatibility
(HAC) rating for this mobile phone, use only the original equipment
battery model.
The ratings are not guarantees. Results will vary depending on the
user's hearing device and hearing loss. If your hearing device happens
to be vulnerable to interference, you may not be able to use a rated
phone successfully. Trying out the phone with your hearing device is
the best way to evaluate it for your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are
likely to generate less interference to hearing devices than phones that
are not labeled. M4 is the better/higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet FCC requirements and are
likely to be more usable with a hearing device's telecoil ("T Switch" or
"Telephone Switch") than unrated phones. T4 is the better/higher of
the two ratings. (Note that not all hearing devices have telecoils in
them.)
Hearing devices may also be measured for immunity to this type of
interference. Your hearing device manufacturer or hearing health
professional may help you find results for your hearing device. The
more immune your hearing aid is, the less likely you are to experience
interference noise from mobile phones.
