Safety Guidelines
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 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 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.
Hearing devices may also be rated. Your hearing device manufacturer or hearing health
