What is Auditory Brain Response testing (ABR)?
Auditory brain response (ABR) testing is a type of hearing test that can be used to assess how well the auditory system is functioning. This test can be particularly helpful in diagnosing hearing loss in infants and young children. ABR testing may also be recommended for adults who have difficulty understanding conversational speech, those who have tinnitus, or have difficulty hearing despite wearing hearing aids.
What is Auditory Brainstem Response (ABR)?
Auditory Brainstem Response (ABR) is an advanced form of testing used to measure the response of a person's auditory pathway from the inner ear to the brain. This testing can help identify hearing issues in children and diagnose potential health problems. During ABR, the patient wears earphones and electrodes are attached to their scalp; sound is then played through the headphones, which stimulates their auditory nerve pathways. When these pathways are stimulated, electrical signals travel along them back to the electrodes on their scalp, allowing the audiologist to measure their brainwave activity in response to each sound. This allows for testing to be performed on infants and young children who can't participate in traditional hearing testing.
How is ABR used to test hearing in newborns and infants?
Auditory Brainstem Response (ABR) testing is routinely used to measure the hearing in newborns and infants. During this non-invasive testing, electrodes are placed on the baby's head and small amounts of sound are delivered through earphones or auditory transducers. In response, electrical signals in the brain and nerves are measured to assess hearing ability. This makes ABR an accurate tool for detecting hearing impairments in young children, as the test can be done while they sleep and results can be obtained relatively quickly. While it was previously only used when there were signs of a possible hearing loss, ABR testing is now recommended for all newborns as part of their overall health assessment. Early detection of hearing loss allows for early access to necessary interventions and a better chance at communicating effectively with the world around them.
What are the benefits of early diagnosis of hearing loss through ABR testing?
Auditory Brainstem Response (ABR) is a reliable and efficient way to test and diagnose hearing loss in newborns and infants. Early diagnosis through ABR testing allows families the opportunity to begin treatment right away and gives their child a better chance of successful outcomes down the road. Hearing loss can be vast and complicated, but with the help of pediatric specialists at our practice, your family can get access to answers and resources you need.
