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 M6 or more would indicate
excellent performance.
However, these are not guarantees that all users
will be satised. T-ratings work similarly.
M3 + M2 = M5
T3 + T2 = 5
The HAC rating and measurement procedure are
described in the American National Standards
Institute (ANSI) C63.19 standard.
