Samsung SCH-I535MBPVZW - Manual (Page 29)

Health and Safety Information 24
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.
