The intent of the HAC Act is to ensure reasonable access to telecommunications services for persons with hearing disabilities. While some wireless mobile devices 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 mobile devices also vary in the amount of interference they generate. The wireless telephone industry has developed a rating system for wireless mobile devices to assist hearing device users find mobile devices that may be compatible with their hearing devices. Not all mobile devices have been rated. Mobile devices 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 mobile device successfully. Trying out the mobile device with your hearing device is the best way to evaluate it for your personal needs. M-Ratings: Mobile devices rated M3 or M4 meet FCC requirements and are likely to generate less interference to hearing devices than mobile devices that are not labeled. M4 is the better/higher of the two ratings. T-Ratings: Mobile devices rated T3 or T4 meet FCC requirements and are likely to generate less interference to hearing devices than mobile devices that are not labeled. T4 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 mobile device rating values are then added together. 98

The intent of the HAC Act is to ensure reasonable access to telecommunications
services for persons with hearing disabilities. While some wireless mobile devices
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 mobile devices also vary in the
amount of interference they generate.
The wireless telephone industry has developed a rating system for wireless mobile
devices to assist hearing device users find mobile devices that may be compatible
with their hearing devices. Not all mobile devices have been rated. Mobile devices
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 mobile device successfully. Trying
out the mobile device with your hearing device is the best way to evaluate it for your
personal needs.
M-Ratings
: Mobile devices rated M3 or M4 meet FCC requirements and are likely
to generate less interference to hearing devices than mobile devices that are not
labeled. M4 is the better/higher of the two ratings.
T-Ratings
: Mobile devices rated T3 or T4 meet FCC requirements and are likely
to generate less interference to hearing devices than mobile devices that are not
labeled. T4 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 mobile device rating values are then added together.
