Probe performance is crucial for accurate OAE testing. That's why we recommend that you conduct a probe test at the beginning of each day before starting to test on patients.
- Do a visual inspection of the probe tip to ensure it is clean and free of wax and debris.
- Carry out a probe cavity test. Insert the probe tip without an ear tip attached into the test cavity. Run a default OAE test protocol and allow it to finish automatically – do not manually stop the test. Please note that there are different cavities for different devices.
- A functioning probe will show no OAE response when using the cavity. You are ready to start testing your patients
- If the probe status displays 'Too noisy', this indicates that the environment is too noisy for testing or there is a probe fault. Stop the test, clean the probe and/or move to a quieter area and perform the test again. Read more about how to keep the noise down here
- If an OAE response is detected during the cavity test, remove the probe from the cavity, re-clean the probe tip and redo the test.
Remember… Always conduct the probe test 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.
