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. Hearing devices may also be rated. Your hearing aid manufacturer or hearing health professional may help you find this rating. Higher ratings mean that the hearing device is relatively immune to interference noise. Under the current industry standard, American National Standards Institute (ANSI) C63.19, the hearing aid and wireless mobile device rating values are added together to indicate how usable they are together. For 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 equals M5. 150 Under the standard, this should provide the hearing aid user with normal use while using the hearing aid with the particular wireless mobile device. A sum of 6 or more would indicate excellent performance. However, these are not guarantees that all users will be satisfied. T ratings work similarly. M3 + M2 = 5 T3 + T2 = 5 The HAC rating and measurement procedure are described in the American National Standards Institute (ANSI) C63.19 standard.

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.

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.
Hearing devices may also be rated. Your hearing aid
manufacturer or hearing health professional may help you find
this rating. Higher ratings mean that the hearing device is
relatively immune to interference noise.
Under the current industry standard, American National

M2 level rating and the wireless mobile device meets the M3
level rating, the sum of the two values equals M5.
Under the standard, this should provide the hearing aid user with

wireless mobile device. A sum of 6 or more would indicate
excellent performance.
However, these are not guarantees that all users will be satisfied.
