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
