Is it normal for a newborn to fail hearing test?
If your baby does not pass the hearing screening at birth, it does not necessarily mean that she is deaf or hard of hearing. Fluid or vernix inside the baby’s ear, for example, or too much noise in the room can affect results. In fact, most babies who do not pass the newborn screening have typical hearing.
What happens if my baby failed the hearing test?
If your newborn fails the hearing screening, arrange for follow-up testing as soon as possible. If your baby has hearing loss, having them tested and treated right away will likely produce better outcomes for your baby. Your baby will receive ABR and OAE testing at their follow-up evaluation at CHOP.
What is a failed hearing screening test?
A screening failure was defined by the guidelines as the inability to detect 1 or more frequencies at 20-dB HL in either ear. The guidelines recommended tympanometry on any child who failed a screening, with appropriate follow-up recommendations based on the tympanometry results.

Why do C section babies fail hearing test?
But Smolkin and Makhoul said it is likely related to fluids in the middle ear. Normally, a baby’s journey through the birth canal pushes those fluids out. A baby born by C-section bypasses all of that — and the middle-ear fluids are retained for a couple days.
How often are newborn hearing tests wrong?
Results: Confirmed hearing loss occurred in 8 nonneonatal intensive care unit infants, a rate of 2.5/1000. Eighty percent of newborns who failed the initial hearing screen passed on rescreening before hospital discharge. This produced a false-positive rate of 0.8% and a corresponding positive predictive value of 24%.
How do you know if your newborn has hearing loss?
Two common tests are used to screen newborn infants for hearing loss:
- Auditory brain stem response (ABR) test. This test uses patches, called electrodes, to see how the auditory nerve reacts to sound.
- Otoacoustic emissions (OAE) test. Microphones placed into the baby’s ears detect nearby sounds.
How can I tell if my baby has hearing loss?
Signs of hearing loss in your baby can include:
- Not being startled by loud sounds.
- Not turning toward a sound after he’s 6 months old.
- Not saying single words like “mama” or “dada” by the time he’s 1 year old.
- Turns his head if he sees you, but not if you only call out his name.
- Seems to hear some sounds but not others.
How common is fluid in newborn ears?
Middle ear fiuid is a very common cause of a failed newborn hearing screen and is found in about 6 out of every 10 children who fail. The fiuid will often go away on its own in the first few months of life, but if it does not, it may require help from a doctor to remove it.
