Figure 3.

Spread of suppression, by subject. The spread of variability in tinnitus suppression percentage across all conditions is shown for each subject. Subjects are listed across the x-axis and grouped as Responders (left) or Non-Responders (right). Each open circle represents the maximal tinnitus suppression for a given condition. Bilateral tinnitus percepts for subjects S3, S5, S6, and S8 are listed by ear. Symbols at −100% suppression (complete adaptation) were shifted by up to 5% for visualization purposes. A dotted line is shown at −30% suppression to indicate the cutoff for successful suppression.
