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 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 pho ne 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.
