Trying out the phone with your hearing device is the best way to evaluate it for your personal needs. 17 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's acceptable for normal operation. 173

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 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’s
acceptable for normal operation.
