A brainstem auditory evoked response (BAER) test measures how your brain processes the sounds you hear. The BAER test records your brainwaves in response to clicks or other audio tones that are played for you. The test is also called a brainstem auditory evoked potentials (BAEP) or auditory brainstem response (ABR) test.
A BAER test can help to diagnose hearing loss and nervous system disorders, especially in newborns, young children, and others who may not be able to participate in a standard hearing test.
BAER tests are often administered to canines and are the only scientifically reliable way to test a dog’s ability to hear with one or both ears.
The mean latency time of waves I, II, III, IV, V and the inter-peak latencies (IPL) were measured. The mean of the latencies in milliseconds was the following: wave I, 1.79 (SD 0.20); wave II, 2.88 (SD 0.28); wave III, 4.54 (SD 0.31); wave IV, 5.86 (SD 0.36); wave V, 6.75 (SD 0.38); IPL, I-III, 2.75 (SD 0.36); III-V, 2.22 (SD 0.22); and finally I-V, 4.97 (SD 0.43).
