5.5.3.2 Placement of Headphones (for Testing with Headphones)
Eliminate any obstructions which will interfere with the placement of the earphone
cushions on the ear (i.e. hair, eyeglasses).
Ensure that the headphones are positioned correctly: red phone on the right ear, blue
phone on the left ear. Adjust the headband of the headphones so that the earphones are
positioned at the correct height (i.e. the sound output grid exactly facing the ear canal).
5.5.3.3 Placement of Foam Eartips (for Testing with Insert Earphones Only)
Figure 92
First, place the eartip securely on the white adapter at the
end of the insert earphone tubing. To prepare the foam
eartip for insertion in the ear canal, you must compress
the foam by rolling it in your fingers to narrow its diameter
(Figure 92). Check to be sure that the foam does not
obstruct the opening of the black sound tube.
Figure 93
Quickly, while the foam is still compressed, grasp the
patient’s ear and gently pull it up and back to open and
straighten the ear canal. While holding the canal open, slide
the compressed foam ear tip into the ear canal. The foam
should be completely surrounded by the canal with virtually
none of the foam sticking out of the canal (Figure 93).
5.5.4 Testing
– Audiometry
5.5.4.1 Air Conduction Testing
Threshold Determination
The test normally starts at 1000 Hz on the patient's better ear. Select Right/Left. A
procedure of
“down 10 dB, up 5 dB”
is typically utilized to establish a threshold at
each frequency.
Screening
A hearing screening utilizes a Pass or Refer result and is used to determine if further
testing is required as a hearing problem may exist. Patients are typically screened at
a level of 20 dB HL at 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz in each ear. If a patient
hears all the tones in each ear, the result would be considered a Pass. Failure to hear
any of the tones in either ear would result in a Refer.
NOTE : This is an example of one screening protocol. Each state may have their own
screening protocol. Contact your state health department for guidelines in your area.
