If either the fit or the noise level is not acceptable you need to improve the situation
before the screening begins:
•
Make sure the probe tip is inserted securely into the ear canal.
•
Quiet the baby or attend to any acoustic noise in the test environment.
After approximately 20 seconds of probe checking, a time out message will appear.
Upon dismissing the message, the initial test screen will appear again. No test will be
saved in this case.
The TEOAE process includes an “adjusting level” phase immediately after the probe fit check.
NOTE : The TEOAE probe fit and
“adjusting level” process is optimized for infant
ears. Some ears with larger canal volume may not pass through this phase of the
TEOAE process. These ears cannot be screened.
OAE Measurement Screen
During the OAE measurement, a bar graph for each of the frequencies in the test protocol
reflects the progress toward a Pass (Table 18). The bar will fill in completely with color and a
checkmark will appear above the bar when the criteria for a pass is achieved at that frequency.
Additionally, horizontal bars for probe stability, noise and test progress appear. When
noise and probe stability are acceptable, a checkmark appears next to the horizontal bar.
NOTE : Probe stability during the measurement displays only for TEOAE. For DPOAE a
probe stability measurement comparing the probe output pre- and post-test will be
available with the test record once it is saved, but not during the measurement.

5.11.4.1 Probe Stability
During TEOAE measurement, a Probe stability bar will reflect the status of the probe
in the ear canal. A check will appear at the back of the bar when the probe stability is
adequate. If the probe stability drops below an acceptable level suggesting that the
probe is falling out of the ear, the check will disappear. If this happens you should
check the fit of the probe in the ear.
