Hearing Aid Compatibility (HAC) Rating
The FCC has created a rating system for cellular phones regarding their HAC-related performance.
This rating helps consumers with hearing disabilities to find phones that will work well with their
hearing aid devices. The HAC rating and measurement procedure are described in the American
National Standards Institute (ANSI) C63.19:2007.

National Standards Institute (ANSI) C63.19:2007.
ANSI C63.19 contains two rating standards: an “M” rating from 1 to 4 for hearing aids operating in
microphone mode, and a “T” rating from 1 to 4 for hearing aids operating in telecoil mode.
microphone mode, and a “T” rating from 1 to 4 for hearing aids operating in telecoil mode.
M-Rating stands for Microphone rating and indicates the amount of reduction of RF interference
between the telephone and the hearing aid in acoustic coupling mode (also called microphone
mode).
between the telephone and the hearing aid in acoustic coupling mode (also called microphone
mode).
Phones rated M3 or M4 meet FCC requirements and generate less interference to hearing devices
set in microphone mode. T-Rating stands for telecoil rating and represents inductive coupling with
hearing aids that are operating in telecoil mode. A telecoil is a small piece of tightly wrapped wire
built into some hearing aids. While the microphone of a hearing aid picks up all sounds, the telecoil
will only pick up an electromagnetic signal from the telephone. Thus, users of telecoil-equipped
hearing aids are able to communicate over the telephone without the amplification of unwanted
background noise.

A combination of M-rating and T-rating defines the final HAC rating and is a deciding factor in
selecting cellular phones for people with hearing problems. A HAC compliant phone could be rated:
