Neonatal hearing screening is a test that is performed on newborn babies to detect any hearing loss early on. This screening is typically done before the baby leaves the hospital, usually within the first few days of life.
There are two main types of neonatal hearing screening tests: otoacoustic emissions (OAE) and auditory brainstem response (ABR). OAE testing involves placing a small probe in the baby's ear to measure the response of the inner ear to sound. ABR testing involves placing electrodes on the baby's head to measure the response of the auditory nerve and brainstem to sound.
Early detection of hearing loss is important because it allows for early intervention and treatment, which can help prevent delays in speech and language development. If a baby does not pass the initial screening, further testing may be done to confirm the presence of hearing loss and determine the degree of impairment.
Overall, neonatal hearing screening is a valuable tool in ensuring that babies with hearing loss receive the support and services they need to thrive and reach their full potential.

Neonatal Hearing Screening
Introduction
Neonatal hearing screening is a crucial public health measure to identify and intervene early in children with hearing loss. Hearing loss in infants can have a profound impact on their development and overall communication and social skills. Early diagnosis and intervention can significantly improve hearing outcomes and maximize future opportunities for children.
Goals of Neonatal Hearing Screening
- Identify newborns with hearing loss before they exhibit any noticeable symptoms.
- Ensure timely and appropriate intervention to minimize developmental delays and adverse effects.
- Facilitate early access to hearing amplification or other necessary services.
- Reduce the incidence of speech and language problems associated with hearing loss.
- Increase awareness among parents and health care professionals about the importance of early hearing detection.
Screening Methods
Two primary hearing screening methods are used in newborns:
1. Otoacoustic Emissions (OAE)
- Measures sound waves generated by the inner ear in response to sound stimuli.
- Quick, non-invasive, and provides information about the outer and middle ear function.
2. Auditory Brainstem Response (ABR)
- Measures electrical signals in the brainstem in response to auditory stimuli.
- More sensitive than OAE, but requires sedation or sleep.
When is Hearing Screening Performed?
- Screening should be initiated as soon as possible after birth, ideally within the first 1-2 days of life.
- All infants should undergo hearing screening before hospital discharge.
Referral and Follow-up
- Infants who fail the initial screening should be referred for a comprehensive audiological evaluation.
- The evaluation involves additional tests to confirm hearing loss and determine the type and severity of the impairment.
- Early intervention services should be initiated immediately if hearing loss is confirmed.
Benefits of Neonatal Hearing Screening
- Early identification of hearing loss allows for prompt intervention, improving long-term outcomes.
- Reduces the risk of speech and language delays, cognitive deficits, and social isolation.
- Provides peace of mind to parents and families.
- Saves health care costs associated with late diagnosis and interventions.
Current Status and Implementation
- Neonatal hearing screening is mandated by law in most developed countries.
- The Joint Commission requires all hospitals that provide newborn care to implement newborn hearing screening programs.
- The Early Hearing Detection and Intervention (EHDI) program in the United States provides resources and support for screening and early intervention services.
Conclusion
Neonatal hearing screening is an essential public health measure that allows for early identification and intervention in children with hearing loss. By implementing universal screening programs and providing timely access to appropriate services, we can ensure that all infants have the opportunity to reach their full potential in communication and overall development.
