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 in finding 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
phone has an M4 and a T4 rating.
These ratings are not guarantees. Results will vary depending
on the user’s hearing device and the individual’s 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
