Otoacoustic Emission Testing (OAE)
Diagnostic otoacoustic emissions(OAE) can be used in combination with Auditory Brainstem Response testing, as well as behavioral hearing testing to more definitely diagnose a child with hearing loss. This test can be performed on any child of any age. A small insert earphone containing a microphone is placed in the child’s ear, and multiple tones are presented. The microphone records “echo-like” responses created by the child’s inner ear, determining the functionality of the cochlea.
OAE testing is also one of many evaluative tools used in a battery of tests in the diagnosis of Auditory Neuropath Spectrum Disorder (ANSD).
