Using Your Phone With a Hearing Aid
Device
On July 10, 2003, the U.S. Federal Communications
Commission (FCC) Report and Order in WT Docket 01-309
modified the exception of wireless mobile devices under the
Hearing Aid Compatibility Act of 1988 (HAC Act) to require
digital wireless mobile devices 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 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.
The wireless telephone industry has developed a rating system
for wireless mobile devices to assist hearing device users find
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 a label
located on the box.
Your SPH-M380 has an M4 T3 rating
.
These ratings are not guarantees. Results will vary depending
on the user’s hearing device and individual type and degree of
hearing loss. If a hearing device is particularly vulnerable to
interference noise; even a phone with a higher rating may still
cause unacceptable noise levels in the hearing device. 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 for
hearing aid compatibility and are likely to generate less
interference to hearing devices than unrated phones. (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 aid devices may also be measured for immunity to
interference noise from wireless phones and should have
ratings similar to phones. Ask your hearing healthcare
professional for the rating of your hearing aid. Add the rating of
your hearing aid and your phone to determine probable
usability:
䢇
Any combined rating equal to or greater than six offers
excellent use.
䢇
Any combined rating equal to five is considered normal use.
䢇
Any combined rating equal to four is considered usable.
