3. HEARING AID COMPATIBILITY HAC FOR WIRELESS TELECOMMUNICATIONS DEVICES
THIS PHONE HAS A HAC RATING OF M4/T3. 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 standards 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 tele-coil mode thus reducing unwanted background noise.
HOW WILL I KNOW WHICH WIRELESS PHONES ARE HEARING AID COMPATIBLE?
The Hearing Aid Compatibility rating of this smartphone is M4/T3. 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 (tele-coil
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.
