The ABR (Auditory Brainstem Response) test is a non-invasive and precise method to evaluate the function of the auditory nerve and brainstem in response to sound.
What Does the ABR Test Assess?
🔹 Transmission of auditory signals from the ear to the brain
🔹 Health of the auditory nerve
🔹 Hearing disorders in infants, children, and adults
🔹 Detection of neural hearing loss or central auditory system damage
Who Needs an ABR Test?
👶 Infants suspected of hearing loss (newborn hearing screening)
👂 Children who cannot cooperate with behavioral hearing tests
🧠 Adults suspected of auditory nerve tumors or auditory neuropathy
🟪 How Is It Performed?
Electrodes are placed on the forehead and behind the ears. Sounds are delivered via headphones, and the device records the brain’s electrical responses.
📌 The test is painless and does not require active participation.
(In infants, it is usually performed during natural sleep or with mild sedation.)
How Do the Results Help?
✅ Determine the type and degree of hearing loss
✅ Identify neural hearing disorders
✅ Guide decisions for hearing aids or other therapeutic interventions
