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.
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.
