Helpful Hints
· Minor irritation and/or inflammation may occur as your ear
becomes accustomed to having an object in it; if so, please
contact your hearing professional. There are several different
sizes of ear domes that may be more comfortable.

Reposition your hearing
aids in their slots,
ensuring the contact points
are touching the charge
points in the case.
Please review the following simple communication tips:
For You
- Move closer to and look at the speaker
- Sit face-to-face in a quiet room if possible
- Try out different locations to find the optimal places to
listen
- Minimize distractions
- Background noises may be frustrating at first; remember,
you have not heard them for a while
- Let others know what you need; keep in mind that people
cannot “see” your hearing loss
- Develop realistic expectations of what your hearing aids
can and cannot do
- Better hearing with hearing aids is a learned skill combin-
ing desire, practice, and patience. You will learn and adjust, it
just takes a little time. Remember to be patient with yourself.
For Your Family and Friends
Your family and friends are also affected by your hearing loss.
Request that they:
- Get your full attention before beginning to speak
- Look at you or sit face-to-face
- Speak clearly and at a normal rate and level; shouting can
actually make understanding more difficult
- Rephrase rather than repeat the same words; different
words may be easier to understand
- Minimize distractions while speaking
VIII.TIPS FOR BETTER COMMUNICATION
It will take practice, time, and patience for your brain to adapt
to the new sounds that your hearing aids provide. Hearing is
only part of how we share thoughts, ideas and feelings.
Reading lips, facial expressions, and gestures can help the
learning process and add to what amplification alone may
miss.
