FCC Hearing-Aid Compatibility (HAC) Regulations for
Wireless Devices
On July 10, 2003, the U.S. Federal Communications Commission (FCC) Report
and Order in WT Docket 01-309 modified the exception of wireless phones under
the Hearing Aid Compatibility Act of 1988 (HAC Act) to require digital wireless
phones be compatible with hearing-aids. The intent of the HAC Act is to ensure
reasonable access to telecommunications services for persons with hearing
disabilities.
While some wireless phones are used near some hearing devices (hearing aids
and cochlear implants), users may detect a buzzing, humming, or whining noise.
Some hearing devices are more immune than others to this interference noise,
and phones also vary in the amount of interference they generate.
The wireless telephone industry has developed a rating system for wireless
phones, to assist hearing device users find phones that may be compatible with
their hearing devices. Not all phones have been rated. Phones that are rated
have the rating on their box or a label located on the box.
The ratings are not guarantees. Results will vary depending on the user’s hearing
device and hearing loss. If your hearing device happens to be vulnerable to
interference, you may not be able to use a rated phone successfully. Trying out
the phone with your hearing device is the best way to evaluate it for your
personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to
generate less interference to hearing devices than phones that are not labeled. M4
is the better/higher of the two ratings.
Hearing devices may also be rated. Your hearing device manufacturer or
hearing health professional may help you find this rating. Higher ratings mean
that the hearing device is relatively immune to interference noise. The hearing
aid and wireless phone rating values are then added together. A sum of 5 is
considered acceptable for normal use. A sum of 6 is considered for best use.

In the above example, if a hearing aid meets the M2 level rating and the wireless
phone meets the M3 level rating, the sum of the two values equal M5. This
should provide the hearing aid user with “normal usage” while using their
hearing aid with the particular wireless phone. “Normal usage” in this context is
defined as a signal quality that is acceptable for normal operation.
The M mark is intended to be synonymous with the U mark. The T mark is
intended to be synonymous with the UT mark. The M and T marks are
recommended by the Alliance for Telecommunications Industries Solutions
(ATIS). The U and UT marks are referenced in Section 20.19 of the FCC Rules.
The HAC rating and measurement procedure are described in the American
National Standards Institute (ANSI) C63.19 standard.
