									Cell Phones for People with Hearing Aids

Compatibility can be challenging when using a cell phone. By fall 2005, each manufacturer of digital
cell phones must have two products with sufficiently reduced Radio Frequency (“RF” - which typically
causes a lot of interference with hearing aids). By fall 2006, each manufacturer must have two products
that are compatible with the hearing aid's telecoil. This will improve things for hearing aid wearers.

To find a phone with a built-in volume control that works for you, it is recommended that you go to a
place that sells mobile phones and try them out.

Add-on amplifiers
Check with a vendor who specializes in selling products made for people who are deaf or hard of
hearing to see what types of cell phone amplifiers are currently available. Some examples of devices that
are available include:
   •    Plantronics’ MHA100 amplifier that is used with a headset (www.plantronics.com)
   •    Audex’s CHAAMP (www.audex.com/chaamp.html)
   •    Nokia’s Loopset is for people who have a telecoil on their hearing aid, and
   •    Nokia’s HDA-9 adapter allows people to use a TTY or VCO transmission with their cell phone
   •    Motorola’s Hands-Free Neckloop accessory is designed for people who wear telecoil-equipped
        hearing aids. Motorola also offers products that are TTY and VCO compatible
       (http://commerce.motorola.com/consumer/QWhtml/accessibility/features.html ).

There are a number of different features that may make it easier for hearing aid users to use a digital
wireless phone. These features may include, but are not limited to:

   •    “Clam shell" or "flip up" design which contains only the speaker component of the phone (this is
        really important for telecoil users)
   •    Ability to turn the backlight off
   •    Vibrating alert for incoming calls
   •    Selectable ringer tones – different frequencies or patterns may be easier to hear
   •    T-coil coupling
   •    Limited or no interference between the hearing aid and wireless phone
   •    Short messaging service (SMS)
   •    Increased volume control
   •    Headset
   •    Compatibility with a neckloop.                                                      continued

Transmission Technology
Anecdotal reports from hearing aid users, clinical experience and research evidence shows that CDMA
(Code Division Multiple Access) and iDEN (High Speed Circuit Switched Data) transmission
technologies seem to work better (although not necessarily interference free) than GSM (Global System
for Mobile Communications) transmission technology. Carriers using CDMA technology are Verizon
Wireless & Sprint PCS. Nextel uses iDEN technology.
