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.
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 phone 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 phone meets the M3 level rating,
the sum of the two values equal M5. This should provide
the hearing aid user with “normal usage” while using their
hearing aid with the particular wireless phone. “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.
