How to ensure your probe is in tip top condition


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.

1. Do a visual inspection of the probe tip to ensure it is clean and free of wax and debris.

2. 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.

3. A functioning probe will show no OAE response when using the cavity. You are ready to start testing your patients

4. 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

5. 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.


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.
