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: Wireless 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. M-ratings refer to enabling acoustic coupling with hearing aids that do not operate
in telecoil mode.
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. T-ratings refer to enabling inductive coupling with hearing aids operating in telecoil mode.
