Otoacoustic Emissions (OAE) Test
Otoacoustic Emissions (OAE) Test
This test can be used to determine if the tiny hair cells in the inner ear are functioning normally. The procedure is painless and can be performed at any age, even in the newborn period. To measure OAEs, a miniature earphone and microphone are placed in the ear canal. Sounds are presented and a response or "emission" from the inner ear is recorded. Patients do not need to respond in any way; they simply need to remain quiet for a few minutes. When testing young children, toys and other visual distracters are used to keep them quiet and calm. The test can be performed while the child is asleep.
