Prepare the equipment
Test environment
The ideal test environment for OAE testing is a quiet room. Loud ambient background noise adversely affects OAE measurements.
Prepare the baby
The baby should be sleeping or in a quiet and relaxed state. Sucking, blinking, crying or movement may affect testing.
Place transducer
Place an ear tip onto the probe tip and place the probe in the ear. Avoid holding onto the probe during the measurement as this can produce noise that may affect the test result.
Run test

Prepare the equipment
Test environment
The ideal test environment is a quiet room where lights and other electronic equipment are turned off.
Prepare the baby
Patient state |
The baby should be sleeping or in a quiet and relaxed state. Sucking, blinking, crying or movement may affect testing. |
Skin preparation |
If the baby’s skin is oily or covered in vernix, the electrode placement sites should be cleaned prior to placing the electrodes. |
Place electrodes |
Place surface electrodes using the specified test montage for the selected protocol (mastoid or nape). |
Connect cables |
Connect the cables from the preamplifier to the respective surface electrodes. |
Place transducer
Place the probe or inset earphones in the baby’s ear/s or place the EarCups around the baby’s ears.
Run test
Press the Test button
Impedance check
An impedance check will begin. Impedances are indicated by the green/amber dots on the montage picture as well as in numerical format on the screen.
When a dot is amber, it means the impedance is poor (> 40kΩ) for the indicated electrode. Check that the surface electrode and cables are connected correctly. It may be necessary to re-clean the skin or use a conductive gel with the surface electrodes to achieve an acceptable impedance. Testing cannot begin until impedance indictors are green (< 40kΩ).
