Additional information on Specific
Absorption Rates (SAR) can be found on
the Cellular Telecommunications Industry
Association (CTIA) website at http://

* 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 it for your personal
