The wireless telephone industry has developed a rating system for wireless mobile devices to assist hearing device users find mobile devices that may be compatible with their hearing devices. Not all mobile devices have been rated. Mobile devices 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 mobile device successfully. Trying out the mobile device with your hearing device is the best way to evaluate it for your personal needs. M-Ratings: Mobile devices rated M3 or M4 meet FCC requirements and are likely to generate less interference to hearing devices than mobile devices that are not labeled. M4 is the better/higher of the two ratings. T-Ratings: Mobile devices rated T3 or T4 meet FCC requirements and are likely to generate less interference to hearing devices than mobile devices 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 mobile device 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. M3 + M2 = 5 T3 + T2 = In the above example, if a hearing aid meets the M2 level rating and the wireless mobile device meets the M3 level rating, the sum of the two values equal M5. This is synonymous for T ratings. This should provide the hearing aid user with "normal usage" while using their hearing aid with the particular wireless mobile device. "Normal usage" in this context is defined as a signal quality that is acceptable for normal operation. The M mark is intended to be synonymous with the U mark. The T mark is intended to be synonymous with the UT mark. The M and T marks are recommended by the Alliance for Telecommunications Industries Solutions (ATIS). The U and UT marks are referenced in Section 20.19 of the FCC Rules. The HAC rating and measurement procedure are described in the American National Standards Institute (ANSI) C63.19 standard.

The wireless telephone industry has developed a
rating system for wireless mobile devices to assist
hearing device users find mobile devices that may be
compatible with their hearing devices. Not all mobile
devices have been rated. Mobile devices 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
mobile device successfully. Trying out the mobile
device with your hearing device is the best way to
evaluate it for your personal needs.
M-Ratings
: Mobile devices rated M3 or M4 meet FCC
requirements and are likely to generate less
interference to hearing devices than mobile devices
that are not labeled. M4 is the better/higher of the
two ratings.
T-Ratings
: Mobile devices rated T3 or T4 meet FCC
requirements and are likely to generate less
interference to hearing devices than mobile devices
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
mobile device 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.
In the above example, if a hearing aid meets the M2
level rating and the wireless mobile device meets the
M3 level rating, the sum of the two values equal M5.
This is synonymous for T ratings. This should provide
the hearing aid user with “normal usage” while using
their hearing aid with the particular wireless mobile
device.
“Normal usage” in this context is defined as a signal
quality that is acceptable for normal operation. The M
