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.
