FCC Hearing-Aid
Compatibility (HAC)
Regulations for Wireless
Devices
On July 10, 2003, the U.S.
FederaCommunications
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 digitawireless
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 to find phones that
may be compatible with their
hearing devices. Not alphones have
been rated. Phones that are rated
have the rating on their box or a
labelocated on the box.
The ratings are not guarantees.
Results wilvary 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.
