H �FCC HEARING-AID COMPATIBILITY

(HAC) REGULATIONS FOR WIRELESS
DEVICES

THIS PHONE HAS A HAC RATING OF M4

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 telecom-
munications 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 hear-
ing 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 inter-
ference 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 profes-
sional 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.
