A cochlea that is functioning normally not only receives sound, it also produces low-intensity, measurable sounds called OAEs. OAEs are absent when an infant/child has a sensorineural hearing loss of 30dBHL or greater. It is important to note that middle ear fluid, or negative middle ear pressure associated with otitis media, can interfere with OAE measurement. The middle ear must be clear for OAE equipment to accurately assess cochlear functioning. The condition known as “auditory neuropathy/dys-synchrony” is diagnosed by comparing OAE results (typically normal) with ABR results (typically abnormal)
