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.
The HAC rating and measurement procedure are described in the American National
Standards Institute (ANSI) C63.19 standard.
