However, communication devices such as
digital cell phones can create interference
(a buzzing sound) in hearing aids. If you
experience interference from a cell phone
being used close by, you can minimize this
interference in a number of ways. Switch your
hearing aids to another program, turn your
head in a different direction or locate the cell
phone and move away from it.
