Failure to pass the hearing screening indicates that the baby’s hearing development may be impaired and that there is a possibility of congenital deafness. However, hearing screening can be interfered with by various external factors, which may lead to false positive hearing screening results for your baby. If a three-month-old baby does not pass the hearing screening, or if the baby has already had a hearing screening prior to this and the screening result also fails, the baby is considered more likely to have congenital deafness and needs to be taken to a higher level hospital for further examination to clarify the diagnosis. If your baby does not pass the hearing screening for the first time, you can have your baby’s hearing screened again in 2-4 weeks. Also, for babies who are three months old and can already track sounds and turn their heads, when a hearing screening does not pass, the family can carefully observe the baby’s response to sounds, which also helps to make a diagnosis.
