Hearing Aid Compatibility with
Mobile Phones
Some Motorola phones are measured for compatibility
with hearing aids. If the box for your particular model
has “Rated for Hearing Aids” printed on it, the following
explanation applies.
When some mobile phones are used near some hearing
devices (hearing aids and cochlear implants), users may
detect a buzzing, humming, or whining noise. Some
hearing devices are more immune 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.
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.
