How are infants tested for hearing loss?
A baby’s hearing can be tested hours after birth through two techniques: automated auditory brainstem response screening (ABR) and/or otoacoustic emissions screening (OAE). The ABR monitors brain activity that occurs in response to sound. OAE’s are a quick, non-invasive probe measure that determines if the cochlear, or inner ear, is working normally. Both techniques are painless, easy to administer, relatively inexpensive, and accurate. They can be done while an infant is sleeping. Early diagnosis is of major importance because the earlier the hearing loss is diagnosed the sooner intervention can begin, leading to better communication skills in the child. It is important to remember that these are screening tests. If a concern develops about hearing it is important to have a diagnostic evaluation with an audiologist.
