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.
Hearing Aid
Compatibility (HAC)
with Mobile Phones
When some mobile 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 ratings for some of
their mobile phones, to assist
hearing device users in finding
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 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.
