A method is described for adjusting hearing implant operating parameters for electrode contacts in an implantable electrode array to minimize tinnitus in an implanted patient. A channel tinnitus masking stimulation level is measured for each electrode contact at which maximum tinnitus masking occurs, Ytin,n. A channel threshold stimulation level also is measured for each electrode contact that represents a lowest detectable stimulation level, Tmeas,n. And a channel maximum stimulation level is measured for each electrode contact that represents a maximum comfortable stimulation level, MCLmeas,n. Channel threshold stimulation level Tn and channel maximum stimulation level MCLn are then adjusted for each electrode contact as a function of the channel tinnitus masking stimulation level Ytin,n and tinnitus masking stimulation levels for adjacent electrode contacts, Ytin,adj.
