Test condition information
When conditions are good for data collection
TE 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. If test conditions are not optimum, a
highlighted message is shown to indicate the problem. (See
7.2.3
Checkfit
condition information
).
9.3
Test stop reasons
There are four possible ways in which a test can stop:
AutoStop
,
Maximum NLo Sweeps
,
Test Timeout
and
Manual End
. When the test
stops the data collected is assessed and a result is given as a pop-up
graphic, then as a highlighted message at the top of the test screen. The
Otoport will beep once if a test has stopped with a
TEOAE Pass
result and
will beep twice if the test has stopped with any other result.
9.3.1
AutoStop
If the test data collected meets the set pass criteria then the test will
AutoStop and a large checkmark will be displayed.
9.3.2
Maximum number of NLo sweeps
If a test has not met the set pass criteria it will stop when the
Maximum
NLo Sweeps
(recordings made with a noise level below the rejection
threshold) is reached. This is a representation of the amount of good data
sweeps required before a
No valid OAE
result can be given.
9.3.3
Test timeout
If a test has not met the set pass criteria and the noise is consistently
above the
Noise Reject Threshold Level
so that the
Maximum NLo
Sweeps
cannot be achieved then the test will stop after 300 seconds,
regardless of the amount of good data collected. This is to control stimulus
exposure to the ear and to limit the test time to allow for reassessment of
the ambient noise and of probe fit before a retest.
9.3.4
Manual end
Selecting
End
at any time will stop the test.
