Precautions
The use of hearing aids is only part of hearing
rehabilitation; auditory training and lip
reading instruction may be required as well.
In most cases, infrequent use of hearing aids
does not provide full benefit. Once you have
become accustomed to your hearing aids,
wear your hearing aids everyday all day.
Your hearing aids use the most modern
components to provide the best possible
sound quality in every listening situation.
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.
