The purpose of neonatal hearing screening is to prevent the detrimental effects of hearing loss in infants.

There are generally two possible types of hearing loss in infants:

  • The first category is hearing loss that can be treated with one or more courses of medication or breastfeeding modification.

It should be noted that if this type of hearing loss becomes chronic, there is a possibility of permanent hearing loss.

  • In the second category, depending on the location of the hearing system, according to the diagnosis of hearing specialists, using hearing aids such as hearing aids or cochlear implants, as well as participation in rehabilitation sessions are recommended.

Since the sense of hearing is closely related to children's speech and language, so if therapeutic and rehabilitation interventions are done early, preferably before 6 months of age, they can help in the formation of language and speech and reduce the effects of disability on individual and social life.

In the neonatal hearing screening section, two main and important tests are taken:

  • Oto Acoustic Emission OAE: Evaluation of cochlear function
  • Automated auditory brainstem response AABR:  Evaluation of auditory nerve function

According to the results of each of these two tests, the audiologist will refer the child to specialized centers for medication or rehabilitation interventions.

Note that if the baby has all seven factors that increase the risk of hearing loss, a diagnostic hearing test is required. These factors include:

  • Weight under 1500 grams
  • Head and face deformity
  • Hospitalization in NICU for more than 48 hours
  • Family history of hearing loss
  • Family history of retardation and syndrome
  • History of a strike to the head
  • Being premature
