digital wireless phones be
compatible with hearing-aids.
The intent of the HAC Act is to
ensure reasonable access to
telecommunications services for
persons with hearing disabilities.
While some wireless 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 a rating system
for wireless phones, to assist
hearing device users to find
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 located 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 generate less
interference to hearing devices
than phones that are not labeled.
T4 is the better/higher of the two
ratings.
Hearing devices may also be
rated. Your hearing device
manufacturer or hearing health
professional may help you
find this rating. Higher ratings
mean that the hearing device is
relatively immune to interference
noise. The hearing aid and
wireless phone rating values
are then added together. A sum
of 5 is considered acceptable
for normal use.. A sum of 6 is
considered for best use.
