WHAT IS HEARING AID COMPATIBILITY
The Federal Communications Commission has implemented rules and a rating
system designed to enable people who wear hearing aids to more effectively
use these wireless telecommunications devices. The standard for compatibility
of digital wireless phones with hearing aids is set forth in American National
Standard Institute (ANSI) standard C63.19. There are two sets of ANSI stan-
dards with ratings from one to four (four being the best rating): an “M”
rating for reduced interference making it easier to hear conversations on the
phone when using the hearing aid microphone, and a “T” rating that enables
the phone to be used with hearing aids operating in 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 (micro-
phone 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 PAR-
TICULAR 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.
