The staff at the hospital or clinic want to find the
best hearing aid for each person.
First they find out about the hearing loss.
The audiogram can show a mild,
moderate, severe
or profound hearing loss.
Hearing aids make sounds like speech louder to help
a 'deaf' person 'hear' them. The increase in loudness is called 'gain'.
A person with a severe loss needs more 'gain' than a
person with a moderate loss to 'hear' the full range of speech sounds.
Different hearing aids give different 'gain'.
To find the best hearing aid they do another hearing test with hearing
aids. The results of this test are called an 'aided threshold'.
The
hearing aid prescribed will give the 'gain' needed for the person
to 'hear' the widest range of speech sounds.
Speech
tests (like The Manchester Junior word list (MJ) or The Manchester
Picture Test) may be used to compare different hearing aids or contexts.
