If a baby passes the hearing screening, it means that the baby’s cochlear function is basically normal at the moment, but this does not mean that the baby will never have hearing problems in the future, because there are many delayed hearing losses and external causes such as medications that can cause deafness, which may not manifest for a long time after birth. No matter what time of the year, whenever parents find that their child may have hearing loss, they should have a hearing screening in time for early detection of hearing loss, so parents of babies who have passed should not rest on their laurels and must keep an eye on their child’s hearing and speech development. Once you find that your child has poor response to sound or hearing loss, you must go to a professional hearing center in time to avoid delaying treatment and rehabilitation.
