5.5.2 Perform the Hearing Screening
Once the patient understands the task, continue to the screening process.
1. Change the hearing level to 20 dB HL and press the 1000 Hz button 1-2 seconds
to present the tone to the patient.
2. Record whether the patient responded by raising their hand. Present again to
confirm response at 20 dB HL.
3. Continue the same procedure for the other frequencies. Record all results on the
audiogram card provided.
4. Patients are typically screened at a level of
20 dB HL
at
500 Hz
,
1000 Hz
,
2000 Hz
,
and
4000Hz
in
each ear
. If a patient hears all the tones in each ear, the result would
be considered a
Pass
. Failure to hear even one of the tones in either ear would
result in a
Refer
.
Note
: When presenting tones, be sure to vary the timing of the tone presentation.
This is to prevent the patient from routinely raising his/her hand instead of responding
to the actual tone presentation.
•
Best practice is to confirm each frequencies response before moving to the
next frequency. Limit testing to no more than 4 presentations to reduce false
positive responses.
•
When no response is given at one or more frequencies, reinstruct the patient,
reposition headphones and, when possible, change examiners. Continue
rescreen within the same screening period.
5.5.3 Results
PASS
: The screening is considered a pass result if the child responds to all screening
frequencies in both ears.
REFER
: The child does NOT pass the screening and should be referred for further
testing if:
•
child misses any of the frequencies in either ear, even if it is just one, OR
•
cannot complete the screening process.
