cVEMP evoked by submaximal air conducted 500 Hz tone bursts, delivered at the right ear (left panel) and left ear (right panel). Responses recorded at the ipsilateral sternocleidomastoideus muscle under controlled contraction. The two traces per side represent the averaged response of 120 sweeps. The classical positive-negative EMG deflection within 12–25 ms after stimuli is not identifiable on either a side with responses configuring EMG noise only
