the telecoil mode thus reducing 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 interfer-
ence, if they have wireless phone shielding, and whether your hearing aid has a
HAC rating.
