The investigators combined transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) to increase the effective response of a single session of neuromodulation in subjective tinnitus.

To treat motor and psychiatric disorders, transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) are world-widely in use in clinics. The investigators combined these two types of neuromodulation techniques to increase the effective response of a single session of neuromodulation in subjective tinnitus. Experimental groups with 80 tinnitus subjects consisted of four different treatment groups which are tDCS, tDCS with sham TMS, tDCS-TMS and TMS group. Subjects were given 1.5milliampere (mA) tDCS on the bi-frontal area and TMS stimulated contralateral single side of the temporoparietal cortex with 200 pulses at 1herz (Hz) stimulation.

• Research volunteers who agreed to participate in the clinical trial were gathered from the tinnitus clinic of the Department of Otorhinolaryngology Head-and-Neck Surgery, Seoul National University Bundang Hospital

Exclusion Criteria:

• psychoactive drug user
