Advanced Hearing Evaluation for Infants and Children at Denoc Hearing

The Auditory Brainstem Response (ABR) test is a non-invasive diagnostic tool used at Denoc Hearing to assess hearing sensitivity and neural integrity from the ear to the brainstem, especially in infants and young children who are unable to respond behaviorally to sound.

What is ABR?

The ABR test measures the electrical activity generated by the auditory nerve and brainstem in response to sound stimuli such as clicks or tone bursts. This helps determine whether sound is being effectively transmitted from the outer ear through to the brain.

Clinical Procedure

  •  Your child will lie down in a calm, quiet environment—either on a reclining chair or bed.
  • Small electrodes are placed on the forehead, earlobes, and scalp.
  • Soft clicking sounds or tone bursts are delivered via earphones.
  • The electrodes capture the brain’s responses to sound, which are analyzed through a computer system.
  • Results are displayed in the form of waveforms, indicating how sound is transmitted through the auditory pathway.

Patient Preparation

No special preparation is needed apart from a hair wash the night before.
If your child has any health or developmental concerns, please inform Denoc’s audiology team in advance.
Infants and toddlers must be asleep for accurate results. Parents are encouraged to plan naps or feeding schedules accordingly.
Children over 7 years can be tested awake, but must remain still and relaxed.

No, ABR is a completely painless and non-invasive test that only requires your child to be still or asleep during the session.

Yes. In fact, feeding your baby before the session may help them fall asleep, which is ideal for ABR testing in infants.

ABR is recommended when there is a concern about a child’s hearing, especially in newborns, delayed speech cases, or uncooperative young children during regular hearing tests.
