How accurate is the newborn hearing test?
Although the test is relatively accurate, it sometimes fails to detect hearing impairments. This is known as a “false negative” test result. Sometimes newborns with normal hearing get a wrong diagnosis after having an OAE test: Although they can hear well, they are mistakenly diagnosed as being hard of hearing.
How common is it for a newborn to fail hearing test?
Between 2 and 10 percent of all babies across the United States do not pass their first hearing screen, but very few of these babies have permanent hearing loss. Babies can fail the newborn hearing screening due to vernix in the ear canal, fluid in the middle ear, or because of movement or crying during the test.
How can I tell if my newborn is deaf?
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.
When should I be concerned about my newborn’s hearing?
When to Worry About Your Baby’s Hearing
If your newborn does not respond to loud sounds with a startle reaction or never seems to react to your voice in the first months, run it by your pediatrician. Most states now require newborn screening for hearing loss, so you will know early on that your baby’s hearing is OK.
What happens if newborn failed 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.
Do deaf babies cry?
Results. Mean duration of cries in the deaf group was 0.5845 ± 0.6150 s (range 0.08-5.2 s), while in the group of normal hearing cases was 0.5387 ± 0.2631 (range 0.06-1.75 s). From the deaf group, five cases had very prolonged duration of cries, without statistical significance.
Can babies hearing improve?
Changes in hearing thresholds of NICU infants
One infant with normal hearing progressed to severe hearing loss. Five infants who had SNHL in the initial hearing tests showed a hearing threshold improvement of more than 20 dB (mean difference of threshold, 35 dB), and four of them recovered to normal hearing.
Can you damage a baby’s hearing?
Key points about noise-induced hearing loss
Your child’s inner ears may be damaged if he or she is around extremely loud noises or around loud noises for long periods of time. Noise-induced hearing loss is gradual and painless. Once the hearing nerve is destroyed, it is permanent.
Can hearing loss be reversed in babies?
It is often possible to treat hearing loss that is caused by problems in the middle ear with medicines or surgery. There is no cure for hearing loss caused by damage to the inner ear or nerves. How well the baby does depends on the cause and severity of the hearing loss.

Can hearing damage be reversed?
Once damaged, your auditory nerve and cilia cannot be repaired. But, depending on the severity of the damage, sensorineural hearing loss has been successfully treated with hearing aids or cochlear implants. There is, however, the possibility that your hearing loss isn’t reversible.
