In the United States and Canada, the SAR limit for mobile phones used by the public is 1.6 watts/kg (W/kg) averaged over one gram of
tissue. The standard incorporates a substantial margin of safety to give additional protection for the public and to account for any variations
in measurements.
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 to 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 this.
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.
T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely to generate less interference to hearing devices than phones 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 phone rating values are then
added together. A sum of 5 is considered acceptable for normal use. A sum of 6 is considered for best use.
