Hearing aid compatibility
The FCC has adopted hearing aid compatibility (HAC) rules for digital wireless phones. These
rules require certain phones to be tested and rated under the American National Standard
Institute (ANSI) C63.19-2007 hearing aid compatibility standards.
The ANSI standard for hearing aid compatibility contains two types of ratings:
•
An “M” rating for reduced radio frequency interference to enable acoustic coupling with
hearing aids that are not operating in telecoil mode
•
A “T” rating for inductive coupling with hearing aids operating in telecoil mode
