may not be able to use a rated phone
successfully. Trying out the phone with
your hearing device is the best way to
evaluate it for your personal needs.
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.
T-Ratings: Phones rated T3 or T4 meet
FCC requirements and are likely to
generate less interference to hearing
devices than phones 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
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 is synonymous for T ratings.
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
