2.6.4 Use with Hearing Aids – FCC
When some wireless 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 wireless devices also
vary in the amount of interference they generate. In the event of interference, you may want
to consult your hearing aid supplier to discuss solutions.
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.
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.
ANSI C63.19 Rating System
In accordance with FCC hearing aid compatibility rules, certain phones be tested and rated
under the American National Standard Institute (ANSI) C63.19 hearing-aid compatibility
standard. This standard contains two types of ratings:

M-Rating: For reduced radio-frequency interference to enable acoustic coupling
with hearing aids that don’t operate in telecoil mode

T-Rating: For inductive coupling with hearing aids operating in telecoil mode (t-
switch or telephone switch)
These ratings are on a scale from one to four, where four is the most compatible. A phone
is considered hearing-aid compatible under the FCC requirements if it's rated M3 or M4 for
acoustic coupling and T3 or T4 for inductive coupling.
Hearing devices may also be measured for immunity to this type of interference. Your
hearing device manufacturer or hearing health professional may help you find results for
your hearing device. The more immune your hearing aid is, the less likely you are to
experience interference noise from mobile phones.
Hearing Aid Compatibility
