Newborn Hearing Screening Methods
The two methods considered suitable for hearing screening are OAE (otoacoustic emissions) and AABR (automated auditory brainstem response). OAE testing is quick and inexpensive with regard to the equipment and disposables costs.
AABR testing takes a little more time to perform and the equipment and disposables are more expensive.
AABR typically has better test specificity, meaning that fewer babies with normal hearing will be referred for more tests.
Also, AABR detects hearing problems caused by conditions in the auditory nervous system whereas OAE only detects cochlear hearing loss.
AABR is particularly recommended for babies whose birth history puts them at higher risk for hearing loss.
1. OAE
A probe with a tiny earphone and microphone is placed into the baby’s ear.
The earphone plays sounds which cause an echo in the cochlea. The microphone detects the echo and the system determines whether the response is normal.
The result is presented as "pass“ or "refer“.
2. AABR without Disposables
Electrode gel is massaged on areas of the baby’s head.
Sounds are played through an earphone. Electrodes built into the device measure the brain’s response and the system assesses it.
The result is presented as "pass“ or "refer“.
3. AABR
Disposable electrodes and ear couplers are placed on the baby’s head.
Sounds are played through earphones. The electrodes measure the brain’s response and the system assesses it.
The result is presented as "pass“ or "refer“.
