OAE (Otoacoustic Emissions) Test

First of All
Preparation: The patient is seated in a quiet room, and the ear canal is examined to ensure that there is no blockage or obstruction that could affect the test results.

Two
Stimulus presentation: A soft sound is presented through a small earphone placed in the ear canal. The sound triggers a response from the cochlea, which produces an echo called an OAE.

Three
OAE measurement: A tiny microphone placed in the ear canal records the OAE response, and the signal is analyzed by a computer to determine the level and frequency of the response.


Four
Result interpretation: The audiologist or hearing healthcare professional interprets the OAE results and compares them to expected values to determine if there is any hearing loss.

Five
Follow-up testing: If the OAE test results suggest hearing loss, further testing may be recommended, such as a hearing evaluation or auditory brainstem response (ABR) test.

Six
Counseling and treatment: Based on the OAE test results, the audiologist or hearing healthcare professional may provide counseling and recommend appropriate treatment options, such as hearing aids, cochlear implants, or other interventions.
