A newborn who fails a hearing screening but is startled by sounds cannot be definitively determined to be normal. Their hearing may be normal or abnormal. Newborn hearing screening is often about 2 to 3 days after birth will be the initial screening, but due to this stage of the newborn’s ability to react is relatively poor, or the ear canal with amniotic fluid or bath water, it is easy to hear will not pass the phenomenon, but the newborn’s hearing may be normal, and there are sounds will be startled. It is also possible that the newborn has normal hearing in one ear and a problem with failing the hearing screening in the other ear, but because he or she still has hearing in one ear, he or she may react in a way that makes him or her startle at sounds. A newborn who fails the hearing screening but startles at sounds is not necessarily a sign of hearing abnormality. A second screening is usually needed within 42 days, and if there is an abnormality, early intervention is needed.
