Hearing Aid Compatibility
(HAC)
The FCC has established requirements for
digital wireless mobile devices to be compatible
with hearing aids and other assistive hearing
devices.
When wireless devices are used near hearing
devices (such as 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,
and wireless devices also vary in the amount of
interference that they generate.
The wireless telephone industry has developed
ratings to assist hearing device users in finding
wireless devices that may be compatible with
their hearing devices. Not all wireless devices
have been rated. Wireless devices that are
rated will have the rating displayed on the box
together with other relevant approval markings.
The ratings are not guarantees. Results will vary
depending on the user’s hearing device and
hearing loss. If your hearing device is vulnerable
to interference, you may not be able to use a
rated wireless device successfully. Consulting
with your hearing health professional and
testing the wireless device with your hearing
device is the best way to evaluate it for your
personal needs.
