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 modifi ed 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 to fi nd 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
