OAE test procedure
It is the responsibility of the user to ensure that the pass criteria set meet
their requirements.
Noise level indicator
A Noise Level Indicator is shown on the right of the screen. The bar moves
in response to changes in noise. For good testing conditions the bar
should be consistently below the Noise Reject Level, which is represented
by the horizontal line across the Noise Level Indicator. The bar is filled
red if the level is above the threshold and green if it is below. The noise
level shown is calculated from the peak sound level recorded within each
response window.
The letter below the indicator represents the noise reject threshold level.
This can be altered using the up and down arrow keys.
The noise level indicator allows continuous monitoring of the noise level
during a test.
Test condition information
When conditions are good for data collection DP TEST will be shown at the
top of the screen and progress indicators will move either side of the title to
show that a test is currently running.

Test stop reasons
There are three possible ways in which a test can stop: AutoStop ,
Test Timeout and Manual End . When the test stops the data collected
is assessed and a result given as a pop-up graphic and then written
highlighted at the top of the test screen. The Otoport will beep once if a
test has stopped with a DPOAE Pass result and will beep twice if the test
has stopped with any other result. AutoStop and Stopping (Pass) criteria
are configured in the test settings area (see section
11.3
).
AutoStop
If the test data collected meets the set pass criteria then the test will
AutoStop and a large checkmark will be displayed.
Test timeout
If a test has not met the set pass criteria then the test will stop after 60
seconds.
