unwanted background noise.
How will I know which wireless phones are Hearing
Aid Compatible?
The Hearing Aid Compatibility rating is displayed on the wireless phone
box.
A phone is considered Hearing Aid Compatible for acoustic coupling
(microphone mode) if it has an “M3” or “M4” rating. A digital wireless
phone is considered Hearing Aid Compatible for inductive coupling
(telecoil mode) if it has a “T3” or “T4” rating.
How will I know if my hearing aid will work with a
particular digital wireless phone?
You’ll want to try a number of wireless phones so that you can decide
which works the best with your hearing aids.
You may also want to talk with your hearing aid professional about the
extent to which your hearing aids are immune to interference, if they
have wireless phone shielding, and whether your hearing aid has a HAC
rating.
