FCC Hearing-Aid Compatibility (HAC)

Regulations for Wireless Devices

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 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 with your hearing device is the
best way to evaluate it for your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC
requirements and are likely to generate less
interference to hearing devices than phones that are
not labeled. M4 is the better/higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet FCC
requirements and are likely to generate less
interference to hearing devices than phones that
are not labeled. T4 is the better/higher of the two
ratings.
