"Bifrontal transcranial direct current stimulation (tDCS), with the anodal electrode overlying the right and the cathodal electrode overlying the left dorsolateral prefrontal cortex, has been shown to suppress tinnitus significantly in 30% of patients"

It not very good idea to use this protocol its may work with trinnius bud have side effect turning down DLPFC may couse depresion and sleapines.

I try it 2 times with 1mA 30mins (current density 55uA/cm) to determine a effect if some one use my devece with switched contacts.I ged very sleapy
and hard fousing this last about half a day.
*the setting is little different - cathode on L-DLPFC and anode on right supraorbital area (above right eye)
