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 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 (tele-coil mode) if it has a “T3” or “T4” rating.
