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 labeled. M4 is the better/

higher of the two ratings.

Hearing devices may also be rated. 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
