AUDIOMETRIC TESTING
8.1
Instructing the Patient
Place the subject at ease concerning the test.
Explain the purpose of the test and what kind of
sound or sounds will be heard. An unvarying and
uniform explanation to the person being tested will
help provide test results that are consistently high in
reliability. Instructions might be expressed as
follows: “I am going to place these headphones on
your ears. You will hear a tone or beeping sound
which may be loud or soft. Whenever you hear or
think you hear one of these tones, raise your hand.
Lower your hand when you no longer hear the
tone. Remember, raise your hand when you hear
the tone and lower your hand when you do not.”
Proper placement of the earphones on the ears is
essential
to achieving good test results. Check the
following before placing the earphones on the
person to be tested.
a.
Eliminate any obstructions which will interfere with
placement of the earphone cushion on the ear (i.e.
hair, earrings, eyeglasses, hearing aids, etc.)
b.
Adjust the headband so the earphone cushions are
centered over the ears and the head. The earphone
cushions will put firm pressure on both ears.
