Baby hearing screening is a way to check the development of your baby’s hearing for abnormalities, and is performed around 3-5 days after birth and around 42 days after birth. Failure to pass both ears may be due to interference with the screening, or it may be due to a developmental disorder in the baby’s hearing system or congenital damage to the baby’s hearing. If the baby does not pass the hearing screening at 3-5 days, the baby should be screened again at 42 days. If the baby still does not pass the screening at 42 days, the baby should be screened again at 3 months. Hearing impairment can affect the baby’s speech and language development, so you need to take your baby for further examination as soon as possible to confirm the diagnosis and provide early intervention and treatment. Wear hearing aids or cochlear implant surgery if necessary
