Figure 3: Analog ABR waveforms from subject 4 for right ear stimulation depicting poor morphology and repeatability. The stimuli used were rarefaction clicks presented at a rate of 21.1/ sec. The upper two tracings are ABRs elicited with 80 dB nHL clicks, the lower two tracings are ABRs elicited with 70 dB nHL clicks. The X-axis represents latency (1 ms/div), and the Y-axis represents amplitude (0.4 ýV/div)
