Inconclusive test
If it is not possible to achieve a Pass result and:
•
the patient has a large ear canal volume and the test was started with the Manual Start (
) after a failed calibration,
-or-
•
the test environment is too noisy, the test result may be Inconclusive.
For a large ear canal volume (due to PE tubes or perforation of the eardrum) it may not be possible for the L1/L2 to reach the required
stimulus levels. Adequate stimulus levels are crucial to achieve an accurate response. The result is
Inconclusive
, and a message indicates that
there was a large ear canal volume or a poor probe fit.
If noise exceeds acceptable levels for more than half of the test time, the result is
Inconclusive
and a message indicates that the noise was
too high.
Incomplete test
If the test is stopped, an error message appears. The result screen appears below, if the test failed or was aborted during calibration.
Test completed
Pass/Clear Response and Refer/No Clear Response criteria have not been defined for Protocol 6. Protocol 6 generates a Test Completed
result when all 6 frequencies have been tested.
