Matching Digital Cell Phones
to Hearing Aids

Some results:

• Telecoil users were able to inductively couple to all digital cell phones and hear some level of the intended speech.

• However, for all telecoil users, interference either prevented phone use or limited the digital cell phones usability compared to analog cell or wireline phones

• Although accessories permitted interference free digital cell phone use, they were preferred by only 1 of the 6 telecoil users

• Both mic and telecoil users experienced less interference with CDMA technology than GSM technology

• Analog technology/phones were strongly preferred by the telecoil users, but not the mic users
