How the ratings work
M-Ratings: Wireless devices rated M3 or M4 meet FCC
requirements and are likely to generate less interference to
hearing devices than wireless devices that are not labeled. M4
is the better or higher of the two ratings.
T-Ratings: Wireless devices rated T3 or T4 meet FCC
requirements and are likely to be more usable with a hearing
device's telecoil ("T Switch" or "Telephone Switch") than
unrated wireless devices. T4 is the better or higher of the
two ratings. (Note that not all hearing devices have telecoils
in them.)
Hearing devices may also be measured for immunity to this
type of interference. Your hearing device manufacturer or
hearing health professional may help you find results for your
hearing device. The more immune your hearing aid is, the less
likely you are to experience interference noise from wireless
devices.
For more information about the actions that the FCC has
taken with regard to hearing aid compatibility with wireless
devices and other steps that the FCC has taken to ensure that
individuals with disabilities have access to telecommunications
services, visit www.fcc.gov/cgb/dro.
