How will you screen my baby's hearing?

The automated otoacoustic emissions (AOAE) is the main test used for well babies. However, it is not always possible to see a clear response within the first 24 hours with this test so if a mother is likely to be discharged within 24 hours, her baby's hearing is screened again using a different test, the automated auditory brainstem response (AABR). This is so that a smaller number of babies leave hospital needing follow up. If it is not possible to do an AABR, for example if baby becomes unsettled, then another AOAE screen may be offered in the community.

Babies at high risk are screened using AABR only. High risk babies are babies who have spent more than 48 hours in a Special Care Baby Unit/Neonatal Intensive Care Unit.

Automated Otoacoustic Emissions (AOAE)

A small soft-tipped earpiece is put in the outer part of the baby’s ear. This makes a clicking sound and the equipment shows the screener how the baby’s ears are responding to the sound.

Automated Auditory Brainstem Response (AABR)

Three small sticky pads are put on the baby’s head and neck.  Small headphones are put over the baby’s ears, which will make a clicking sound. The equipment shows the screener how the baby’s ears are responding to the sound.

Both tests are best carried out when the baby is settled or asleep.
