There are many reasons why a newborn baby may not pass the hearing screening. When your baby fails the initial hearing screening, you should pay enough attention to it and follow the professional’s instruction to go to the designated hospital for further hearing re-screening or hearing diagnosis. Newborns and infants who do not pass the re-screening should start the appropriate audiological diagnosis and medical evaluation within 3-6 months, relying on the diagnostic hearing test results to assess whether the child has a hearing impairment.
