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 mobile devices under the Hearing Aid Compatibility Act of
1988 (HAC Act) to require digital wireless mobile devices 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 mobile devices 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 mobile devices
also vary in the amount of interference they generate.
The wireless telephone industry has developed a rating system for
wireless mobile devices to assist hearing device users find mobile
devices that may be compatible with their hearing devices. Not all
mobile devices have been rated. Mobile devices that are rated have
the rating on their box or a label located on the box.
