Otoacoustic emissions (OAE) testing
Otoacoustic emissions (OAE) testing is a noninvasive diagnostic method that helps assess the function of the outer sensory cells in the inner ear.
This procedure is used to objectively evaluate hearing, confirm the results of other audiological tests, and screen newborns for hearing loss.
No special preparation is required. It is important that the ear canals are free of wax, inflammation, and fluid before the examination. If the test is performed on a child, it is best for them to be in a natural state of sleep. If the child has a runny nose, pain, or blocked ears, consult a doctor beforehand.
The patient is placed in a comfortable position in a quiet room. A small probe containing a sensitive microphone and a miniature speaker is inserted into the external auditory canal. Short sound signals are transmitted through the probe into the ear. In response to these signals, the inner ear generates weak sound vibrations, known as otoacoustic emissions. These responses are picked up by the microphone and analysed by the device. The test is performed separately for each ear and takes 5–10 minutes. It is painless and comfortable.
A highly sensitive diagnostic device with a probe system, including a built-in microphone and sound source, is used to detect OAE. Modern audiological systems can automatically record and interpret the results, ensuring accurate and reliable hearing function diagnostics.
After the procedure, patients can immediately return to their normal activities. The examination does not require recovery, does not affect overall well-being, and can be repeated multiple times if necessary, for example, for dynamic observation.
