You will hear some loud repetitive clicking noises but you are not required to respond to them as all measurements are taken automatically by the computer which records the electrical activity in the hearing pathways in the brain. Infants who fail the OAE test twice and infants with risk indicators for neural hearing loss undergo automated auditory brainstem response (ABR) testing as well. You will be required to sit in a dark room with your eyes closed and wearing headphones. The Auditory Brainstem Response (ABR) is a neurophysiological test used to assess the functionality of the central auditory pathway, which includes. ABR tests synchronous neural function and can estimate hearing sensitivity thresholds in individuals who are unable to tolerate traditional behavioral audiometry. The test requires no participation from the patient, allowing the test to be completed on patients as young as 2 weeks old.

How?Īfter cleaning the skin thoroughly to remove surface oils, electrodes will be placed on your forehead and behind your ears and connected to a computer to measure your electrical brain activity (EEG). Auditory brainstem response (ABR), also known as brainstem auditory Evoked Potentials (BAEP), is an objective measurement of auditory pathway function from the auditory nerve to the mesencephalon. What is an ABR Auditory Brainstem Response Testing, also known as ABR Test, is a method of measuring how well the auditory system functions. The central hearing pathways pass close to the central vestibular system (brain balance computer) and may be affected in neurological central balance disorders. It is helpful in assessing possible obstruction to sound transmission due to tumours, demyelination or other problems. Usually, the short-latency response (latency <30 ms). Figure 2 Grand average waveforms for the click evoked ABR in stutterers and controls. The response represents the summated activity of the auditory pathway in response to sound stimulation.

This objective test assesses the central hearing pathways from the cochlea along the auditory nerve all the way to the auditory cortex (the part of the brain where sounds are perceived). (b) Auditory brainstem response to speech sounds in stutterers showed significant prolongations in the onset responses (waves V and A) as well as for the offset response (wave O). An ABR test (Auditory Brainstem Response Test) measures the neural activity of a large portion of the auditory nerve pathway.
