2. Conversation with another person

Sit with someone else in a quiet room. Face each other 
so you can read facial expressions easily. You might 
experience new speech sounds which can seem a little 
disturbing in the beginning. However, after the brain 
has adapted to the new speech sounds, you may hear 
speech clearer.

3. Listen to radio or TV

When listening to the TV or the radio, start out by 
 listening to news commentators since they usually 
speak clearly, then try other programs. 

If you fi nd it diffi cult to listen to TV or radio, contact 
your Hearing Professional for advice about assistive 
listening devices. If your hearing instrument has a 
telecoil program, you may benefi t from using it with an 
induction loop system. 

4. In group conversations

Group situations are usually accompanied by a greater 
degree of background noise. Therefore, making it a 
more diffi cult listening situation. In diffi cult listening 
situations, focus your attention on the person you want 
to hear. If you miss a word, ask the speaker to repeat it.

5. Telecoil use in church, theatre, or cinema 

An increasing number of churches, theatres and public 
buildings have installed induction loop systems. These 
systems send out wireless sound to be received by the 
telecoil in your hearing instruments. Typically, the 
facility will post a sign indicating that an induction 
loop system is available for use by its patrons. 
Contact your Hearing Care Professional for additional 
information.

6. Using the telephone

When using the telephone place the receiver 1-1.5 
inches above your upper part of the ear. It may also 
help to tilt the receiver. If whistling occurs, tilt or 
move the receiver away slightly and try to keep it still. 
If your hearing instrument has a telecoil, try switching 
the instrument to the telecoil program when listening 
on the telephone. Depending on your telephone this 
eliminates any whistling. 

Remember that the telecoil 
operates by detecting 
 magnetic waves. Many 
electrical devices e.g. 
facsimile machines and 
computers emit magnetic 
waves. Make sure that your 
telephone is placed at least 
4-6 feet away from such 
equipment to avoid interference.
