Figure 2: DPOAE amplitude vs. f1 intensity. Data for subject #7 are reported. (a) The grey area corresponds to the linear portion of the DPOAE growth curve, which was subsequently used to evaluate the trigger threshold of the middleear reflex. (b) (1) A reduction in f1 intensity leads to a reduction in DPOAE amplitude (2) The frequency panels in (a,b) correspond to F2
