VAS: Visual Analogue Scale from 0 (the lowest tinnitus loudness) to 10 (the highest tinnitus loudness), the lower VAS shows the better result; C-level: comfortable level at the most basal active electrode; T-level: the threshold level at the most basal active electrode. The lowest VAS indicates the effectiveness of the stimulation in suppressing tinnitus; current level: the stimulation amplitude (the unit is current level [CL] for P01-P05 while it is current unit [qu] for P06-P10); pulse rate: the frequency of stimulation while the unit is pps (pulse per second); electrode: the electrode contact that received the stimulation. The most efficient condition mentioned in the “best” column.
