Figure 4 Speech ABR intensity I/O function for individual patients. (a) A case in which wave V and FFR thresholds were similar. (b) A case in which wave V threshold was better than FFR. (c) A case in which FFR threshold was better than wave V. FFR threshold is marked by an asterisk. ABR, auditory brainstem response; FFR, frequency following response; I/O, input–output.
