Diagram illustrating the input/output functions presumed to be relevant during stimulus conditions of the sort used here. When only tone-alone was presented, the same input/output function (designated Tone-Alone) was relevant for both the single-earphone and two-earphone presentations of each triplet; only the operating point on that function varied. When tone-plus-noise was presented, the cochlear gain was reduced and different input/output functions became relevant. The expanded insert shows the differences between Observed and Expected responses (which is the nSFOAE) for particular tone-alone and tone-plus-noise conditions.
