Figure 4B: Upper Panel A: Analog ABR waveforms from subject 5 depicting poor morphology and repeatability. Upper two tracings were responses for clicks presented at 80 dB nHL in the right ear and the lower tracings are for 80 dB nHL clicks in the left ear. The X-axis represents latency (1 ms/div), and the Y-axis represents amplitude (0.4 ýV/div). Bottom Panel B: Analog MLR waveforms from subject 5 depicting exaggerated amplitude growth for MLR peak Na in the left ear. The upper two tracings are MLRs elicited with 80 dB nHL clicks and the lower two tracings are MLRs elicited with 40 dB nHL clicks. The X-axis represents latency (10 ms/div), and the Y-axis represents amplitude (0.7 ýV/div)
