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 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 rated. M4 is the better/higher
of the two ratings.
RS90 is rated M3.
T-Ratings:
Phones rated T3 or T4 meet FCC requirements and are likely to be more
usable with a hearing aid’s telecoil than phones that are not rated. T4 is the better/higher
