M-Ratings, T-Ratings

Page 45 highlights

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. To ensure that the Hearing Aid Compatibility rating for your phone is maintained, secondary transmitters such as Bluetooth® and WLAN components must be disabled during a call. 45

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 M² or
M³ meet FCC requirements and are
likely to generate less interference to
hearing devices than phones that are
not labeled. M³ is the better/higher of
the two ratings.
T-Ratings:
Phones rated T² or T³
meet FCC requirements and are
likely to be more usable with a
hearing device’s telecoil (“T Switch”
or “Telephone Switch”) than unrated
phones. T³ 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.
To ensure that the Hearing Aid
Compatibility rating for your phone is
maintained, secondary transmitters
such as Bluetooth
®
and WLAN
components must be disabled during
a call.
