device. Trying out the phone with your hearing device is the best way to
evaluate it for your personal needs.
M-Ratings
: Phones rated M3 or M4 meet FCC requirements for hearing aid
compatibility and are likely to generate less interference to hearing devices
than unrated phones. (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 aid devices may also be measured for immunity to interference
noise from wireless phones and should have ratings similar to phones. Ask
your hearing healthcare professional for the rating of your hearing aid. Add
the rating of your hearing aid and your phone to determine probable
usability:
䢇
Any combined rating equal to or greater than six offers excellent use.
䢇
Any combined rating equal to five is considered normal use.
䢇
Any combined rating equal to four is considered usable.
Thus, if you pair an M3 hearing aid with an M3 phone, you will have a
combined rating of six for “excellent use.” This is synonymous for T ratings.
It is further suggested you experiment with multiple phones (even those not
labeled M3/T3 or M4/T4) while in the store to find the one that works best
with your hearing aid device. Should you experience interference or find the
quality of service unsatisfactory after purchasing your phone, promptly
return it to the store where purchased for exchange or refund. More
information about hearing aid compatibility may be found at:
