REGULATIONS FOR WIRELESS DEVICES US VARIANT ONLY
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
