Hearing Aid Compatibility
(HAC) with Mobile Phones
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
