Hearing Aid Compatibility 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.
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 be more
usable with a hearing device’s telecoil (“T Switch” or “Telephone Switch”) than
unrated phones. T4 is the better/higher of the two ratings. (Note that not all hearing
devices have telecoils in them.)
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.
This phone has been tested and rated for use with hearing aids for some of the
wireless technologies that it uses. However, there may be some newer wireless
technologies used in this phone that have not been tested yet for use with hearing
aids. It is important to try the different features of this phone thoroughly and in
different locations, using your hearing aid or cochlear implant, to determine if you
hear any interfering noise. Consult your service provider or the manufacturer of this
phone for information on hearing aid compatibility. If you have questions about return
or exchange policies, consult your service provider or phone retailer.
