Safety and regulatory guide
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 better use. A sum of 8
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. This methodology applies equally for T
ratings. 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.
