A child who can clearly hear but can’t pass the hearing could be the result of an uncooperative crying baby, noisy surroundings, abnormal equipment, or a baby with insignificant hearing loss. Generally full-term newborns are required to undergo hearing screening after 24 hours. If the baby cries more severely during the screening test, or if the surrounding environment is noisy and not quiet, it may affect the baby’s test results. Alternatively, there may be an abnormality in the hospital’s equipment that goes undetected, which may also cause the test results to be wrong. In addition, some congenitally deaf babies may not pass the hearing test if their hearing loss is not obvious and they can hear in life, but they are not sensitive to low frequency sounds. It is recommended to carefully observe your baby’s response to sounds, and if he or she can indeed hear them, talk to your doctor in time, and you can take another test to make it clear.
