Figure 1: Normal cVEMP recordings from noise exposed dental technicians. Left panel shows cVEMP responses recorded from the right ears of Patient 1 (top) and Patient 3 (bottom) and right panel shows cVEMP responses recorded from the right ears of Patient 1 (top) and Patient 3 (bottom). The stimulus was 500 Hz presented at the level of 100 dB nHL. The initial peaks of cVEMP (P1) occurring at about 13 msec followed by negative peaks (N1) occurring at about 23 msec. Each side ranged from 90 to 100 microvolt in size (which is far above the lower limit of normal, approximately 76). Recordings from the other patients were also normal but not included.
