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. Touch by HTC™ is rated

M3.

Please power off the Bluetooth function while using hearing aid devices

with your Touch by HTC™.

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 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.
