Using Your Phone With a
Hearing Aid Device
When some wireless phones are used with
certain hearing devices (including hearing
aids and cochlear implants), users may
detect a noise which can interfere with the
effectiveness of the hearing device.
Some hearing devices are more immune
than others to this interference noise, and
phones also vary in the amount of
interference noise they may generate.
ANSI standard C63.19 was developed to
provide a standardized means of
measuring both wireless phone and
hearing devices to determine usability
rating categories for both.
Ratings have been developed for mobile
phones to assist hearing device users find
phones that may be compatible with their
hearing device. Not all phones have been
rated for compatibility with hearing devices.
Phones that have been rated have a label
located on the box. Your JAX has an M4
and a T4 rating.
These ratings are not guarantees. Results
will vary depending on the user’s hearing
device and individual type and degree of
hearing loss. If a hearing device is
particularly vulnerable to interference
noise; even a phone with a higher rating
may still cause unacceptable noise levels
in the hearing device. 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 for hearing aid
compatibility and are likely to generate less
interference to hearing devices than
unrated phones. (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.)
