Auditory Brainstem Response Audiometry

Newborns who fail a hearing screening require an ABR test. This is done while your baby sleeps in your arms.

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.

Frequently asked questions about Paediatric Hearing Assessments

  • The ears will be checked for inflammation, wax occlusion, glue ear or any other anomalies through otoscopy. Tympanometry is then carried out in order to confirm the presence of glue ear, perforation or wax occlusion. Otoacoustic emissions are performed to check the function of the cochlea. This is a repeat of the test your child will have received at birth.
