Test details
Shows which ear is being tested.
Bar chart
Noise
Registered DPOAE response: Frequency passed
DPOAE frequency being tested, skipped or referred
The height of the bars represents the noise/response amplitude.
The test frequencies are shown below the bar chart.
The test protocols are configurable (see the AccuLink User Manual).
In a standard DPOAE test the 4 frequencies are
•
5 kHz
•
4 kHz
•
3 kHz
•
2 kHz
where 5 kHz is tested first.
The default
Pass/Clear Response
and
Refer/No Clear Response
criterion is 3/4. The test stops automatically if 3 fre-
quencies reach a
Pass/Clear Response
result or 2 frequencies receive a
Refer/No Clear Response
result.
DPOAE
Response at current test frequency.
Noise
Current noise level. Make sure the noise level is as low as pos-
sible.
Progress
Shows the time elapsed for the current test frequency. If a
Pass/Clear Response
for the current frequency is not achieved
the test frequency will time out. Max. time depends on envir-
onmental noise conditions. If test conditions are optimal but
there is no response measured, then the frequency will time out
before the progress bar reaches the end.
