ABR TESTING SCREEN
During the ABR measurement, a bar graph shows the progress toward a Pass result. A
red bar reflects the test progress for the right ear. A blue bar reflects the test progress
for the left ear.
Noise bar
During measurement, a Noise bar will display the amplitude of the incoming EEG
samples. A check will appear at the right side of the bar when the incoming signals are
quiet enough to be accepted and processed in the response detection algorithm. If the
incoming EEG samples contain high noise due to myogenic or electrical noise, the check
will disappear, and the noise bar will reflect noise exceeding the threshold for rejection
of those samples.
Time bar
During measurement, a Time or progress bar will fill in as good sample of data are
processed. When 180 seconds of acceptable EEG samples have been acquired, the bar
will be filled in completely and the test will terminate automatically.
At the end of the test, the screening result symbol appears at the top of the bar graph.
