A newborn hearing test is an audibility test of the newborn. The purpose of this test is to check the proper function of the ears. Usually, a newborn undergoes this test within two days of birth. This test detects the recognition of sound by the inner ear and brain of a newborn. An ENT specialist recognises the errors and starts treatment accordingly.

Methods of conducting a newborn hearing test

Automated otoacoustic emission test or AOAE works by putting the earpiece into the ear of a newborn. The machine plays a gentle sound that is being visualised in wave fronts by a specialist. This test detects the function of hair cells. It detects congenital hearing problems. Cochlear implant surgery treats these hearing problems.

Why the newborn hearing test is important

It is necessary because the ears are one of the most important organs for humans. Without this test, you will not be able to detect problems in hearing. Specialists study the results and start proper treatment of hearing dysfunction. 

Techniques used in Australia for newborn hearing tests

In Australia, the technology used to conduct this test is called (AABR) or an automated auditory brainstem response screening test. The purpose of this test is to detect neural functioning or auditory nerve from the cochlea in the ear to the brain. In this test, earpieces cover the ears, and sensors cover the forebrain, neck, and shoulders. This test checks the response of the newborn towards the sound. This test is painless. Surprisingly, newborns can undergo the test during sleep.
