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.

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 of the two ratings.

RHOD400 complies with the FCC’s requirements for hearing aid compatibility when using the CDMA air

interface. The M rating in this mode is M4 and the T rating in this mode is T3.

Your hearing device manufacturer or hearing health professional may help you find this rating. Higher ratings

mean that the hearing device is relatively immune to interference noise. The hearing aid and wireless phone

rating values are then added together. A sum of 5 is considered acceptable for normal use. A sum of 6 is

considered for better use. A sum of 8 is considered for best use.

In the above example, if a hearing aid meets the M2 level rating and the wireless phone meets the M3 level

rating, the sum of the two values equal M5. This should provide the hearing aid user with “normal usage”

while using their hearing aid with the particular wireless phone. “Normal usage” in this context is defined as

a signal quality that is acceptable for normal operation.
