Auditory Brainstem Response Audiometry

An ABR test is done when a child cannot be tested with behavioural testing methods. The procedure is straightforward and involves technology that records neurological stimuli in the brain.  Adhesive electrodes are carefully placed onto the child's forehead and behind the ears. Sounds at various loudness levels are presented through either earphones or insert earphones and the computer software records the neurological responses originated from the brainstem in response to these sounds. For an accurate reading , babies and children are required to be still and even encouraged to sleep. 

The Auditory Brainstem Response (ABR) Test is performed by highly trained audiologists using sophisticated equipment and is a safe, painless and non-invasive procedure, often done on newborn babies for the early detection of hearing loss in infants. The test takes approximately one hour.
