Hearing Expectations

Set appropriate expectations

It is important that you have the right expectations 

regarding your hearing instruments. Hearing  

instruments can help you hear and understand better, 

but they are not a cure for hearing loss.

People whose expectations are too high (“I thought  

they would make my hearing normal”) are likely to be 

disappointed and may give up.

Hearing instruments can:

 

·

Help you hear and understand better in most  

situations

 

·

Allow you to participate more in group situations  

and meetings

Hearing instruments cannot:

 

·

Give you normal hearing

Hearing instruments may not:

 

·

Let you hear very soft sounds

 

·

Block ALL background noises – especially in noisy 

situations. Even people without hearing loss  

may have difficulty hearing in the presence of  

background noise.
