Using hearing aids with mobile devices
When some wireless mobile 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 mobile 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 devices, to assist hearing device users in finding mobile
devices that may be compatible with their hearing devices. Not all
mobile devices have been rated. Mobile devices that are rated have
the rating on their box or 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
mobile device successfully. Trying out the mobile device with your
hearing device is the best way to evaluate it for your personal needs.
M-Ratings: Mobile devices rated M3 or M4 are likely to generate less
interference to hearing devices than mobile devices that are not
labeled. M4 is the better/higher of the two ratings.
T-Ratings: Mobile devices rated T3 or T4 are likely to be more usable
with a hearing device’s telecoil (“T-Coil Switch” or “Telephone Switch”)
than unrated mobile devices. T4 is the better/higher of the two ratings.
(Note that the hearing aid telecoil must be activated in order for it to
function, and 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 devices.
