FCC Hearing Aid
Compatibility (HAC)
Regulations for Wireless Devices
The U.S. Federal Communications
Commission (FCC) has established
requirements for digital wireless mobile
devices to be compatible with hearing aids
and other assistive hearing devices.
When individuals employing some assistive
hearing devices (hearing aids and cochlear
implants) use wireless mobile devices, they
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.
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 mobile device
successfully. Trying out the mobile device with
your hearing device is the best way to evaluate
it for your personal needs.
