What is Auditory Brainstem Response?
Auditory Brainstem Response examines how the inner ear and brain pathways are working by recording your hearing nerve’s response to various sounds. In other words, it determines your ability to hear. An ABR test is usually ordered if an individual has taken other conventional hearing tests but still cannot pinpoint if they have hearing loss. It is also ordered for babies that fail their initial hearing screening in the hospital. ABR is completely painless and noninvasive but can only be performed if the patient is lying completely still or is sleeping/under anesthesia. This hearing test is most commonly performed on newborns and children, as it is made for those who cannot complete a typical hearing screening.

The hearing care professional will then perform the ABR test on your baby while they are sleeping in your arms or in a crib.
What do the Results from an Auditory Brainstem Response Test Mean?
The lowest tone that one could hear during the test corresponds to the hearing level in that frequency/pitch. The results will be printed from the computer and your hearing care professional will assess them. Depending on how loud the sound had to be before the patient could hear it, if they could hear it at all, the hearing care professional will know if there is a hearing problem present. From there, the patient could be ordered more tests to figure out where the hearing problem stems from and be given a proper diagnosis and treatment plan for the patient’s hearing situation.
How long does it take to get an ABR?
Auditory Brainstem Response does not require the patient to say or do anything but lay completely still for the duration of the test, which is typically 1 to 1.5 hours. For that reason, this hearing test is great for finding hearing problems in young children, especially newborns. If 1 to 1.5 hours is too long of a duration of time to be still, an individual can be given anesthesia to be put asleep. ABR is an efficient way to find out if one has a hearing problem and will tell the hearing care professional if more tests need to be ordered.

What is the ABR used for?
Clinical applications of the ABR include identification of suspected neurological abnormalities of the cranial nerve VIII as well as the associated auditory pathways and the estimation of hearing sensitivity for those who are not able to accurately provide behavioral hearing evaluation information.
What is the purpose of ABR?
ABR measures the synchronous neural fiber activity along the auditory pathway to determine hearing thresholds. Mechanical sound is transformed into electrical signals in the cochlea and transmitted to the brain through the auditory nerve or vestibulocochlear nerve (cranial nerve VIII). Electrical information to the auditory cortex travels along an ascending path through a series of nuclei including the cochlear nuclei, superior olivary complex, lateral lemniscus, inferior colliculi, and medial geniculate nuclei. [5]
What is the brainstem response?
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.

Which part of the brain is the first relay point of the brainstem along the auditory pathway?
[6] The cochlear nucleus is the first relay point of the brainstem along the auditory pathway.
How to perform ABR?
When performing the ABR for a neurological assessment, acoustic stimuli are delivered through insert earphones at a high intensity of 80-90dBnHL for adults at both a standard and high repetition rate. If the patient has hearing loss, the sound intensity can be adjusted to 60-65 dB SL. Hearing Level (HL) is based on the hearing threshold of a normal control population, whereas Sensation Level (SL) is based on the hearing threshold of the tested ear. Thus, 60 to 65 dB SL would imply a stimulus that is 60-65 decibels above the test ear’s threshold of hearing. The intensity of stimulation should be increased by 10 dB increments until reproducible waveforms are obtained, allowing the analysis of thresholds.[18] The resulting waveforms are evaluated for reproducibility, morphology, and latency. The latencies are compared from the right and left sides to determine if there is abnormal neural synchrony or retrocochlear pathology. The Wave V latency should be no more than a 0.4-millisecond difference between ears.
