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 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. Your phone meets the
M4 level rating.Hearing devices may also be rated. Your hearing
device manufacturer or hearing health professional may help you
find this rating.
