It is not uncommon for infants to have binaural hearing screening at about 3 days of age. Clinically, it is not uncommon for infants to have hearing failure, which often means that the infant has abnormal hearing. Infants who do not hear well belong to congenital hearing disorders, and the main causes are genetic factors, embryonic developmental problems and perinatal diseases, such as premature birth, ototoxic drugs such as gentamicin and streptomycin taken by pregnant women during pregnancy, or family genetics (a family member with childhood hearing loss), meningitis and neonatal otitis media, or even brief exposure to noise, can all be congenital hearing disorders in newborns causative factors. However, some infants fail hearing because of the presence of cerumen embolism or amniotic fluid embolism in the external ear canal, as well as the newborn infant’s insensitivity to external sounds. Generally, most infants can pass hearing with success after later care and guidance. If the first hearing screening does not pass, a second hearing screening can be performed 42 days after full term. If the second hearing screening also does not pass, a third hearing screening can be performed 3 months after the baby is born, but it is important to note that the screening should be kept within a quiet environment. If the baby does not pass the third screening, it is important to go to a hospital that has a certificate of hearing diagnosis to diagnose all aspects of the baby’s hearing and to identify the cause so that targeted intervention can be given in a timely manner.
