Daily system checks for OAE devices

It is recommended to perform a daily check of your OAE equipment to ensure that it is in good working order,
before testing on patients. Running a probe integrity test and a real-ear check allows for any probe faults or
system distortions that can masquerade as biological responses to be detected. A daily check ensures that
you can be certain that the results obtained throughout the day are valid.

6.2.1 Probe integrity test

The probe integrity test ensures artifact responses (system distortions) are not being generated by the probe
or hardware.
The probe tip should be inspected for wax or debris prior to conducting the test
•
Testing should always be conducted in a quiet environment
•
• Only use the recommended cavity for testing. Using a different type of cavity may either not detect
probe faults or may incorrectly indicate a faulty probe
Test procedure:
1. Insert the probe into the provided test cavity or ear simulator. It's important to use the correct-sized
cavity for valid test results.
2. Select an OAE test protocol directly from the device or using the Titan Suite. As system distortion is
dependent on stimulus output level, select a protocol that reflects what is used most often in clinical
practice.
3. Start the test and allow it to run until the test stops automatically. Do not stop the test manually.
Test results:
If the probe is functioning correctly, none of the frequency bands (TEOAE) or points (DPOAE) should have a
checkmark, i.e., no artifacts/OAEs should be detected above the noise floor.
No system distortion

For DPOAE a 0.2cc cavity is recommended.
For TEOAE, a 0.5cc cavity is recommended.
