M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to generate less
interference to hearing devices than phones that are not labeled. M4 is the better/higher of the two
ratings.
T-Ratings: Phones 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 phones. T4 is the better/
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 mobile
phones.
