All results are displayed on the screen when the test is finalized:
PASS: test passed the measurement met the set criteria. Detection criteria can be customized in the
setup menu, based on the specific screening or diagnostic needs.
REFER: test failed, no OAE response detected. The measurement did not meet the set criteria.
NOT COMPLETED: test stopped by the operator.
Below the histogram bars the SNR values for the different frequencies are shown.
Stability: this is an indication of the stimulus signal stability. The value indicates the percentage of
valid stimuli on the total.
Artefact: this is an indication of the signal quality assessed during the test. This percentage is
calculated on the number of acquisitions during which noise has been higher than the setup
threshold level.
Noise: test average noise.
The noise, progress and sweep indicators are updated in real time while the test is in progress.
Press SETUP (see picture beside) to open the test setup page.
The menu allows for the setting of a few test parameters:
Adjustable parameters:
Max Sweep
Max test time. By touching this field, the maximum test time, between 30 and 75 seconds, can be
selected. When a valid result is obtained the test is automatically stopped.
Artefact Level
In this field the maximum acceptable noise level can be selected. When the noise exceeds the set
value, the measurement is rejected (artefact). By touching this field, a value between 20 and 60 dB SPL
can be selected.
Stimulus Level
Allows for the setting of the stimulus level. By touching this field, a value between 70 and 90 dB peSPL
can be selected.
Number of frequencies per pass
Minimum number of frequency bands in which the signal to noise ratio needs to exceed the
predefined maximum noise level for the test to be passed.
Frequencies and SNR
The value of the signal to noise ratio for each frequency can be set between 3, 6 or 9 dB, or the
frequency band can be disabled by setting "- ".
