Collaborative Tinnitus Research at Washington University (CTRWU) (version 1.0) - The hypothesis of this study is that rTMS can decrease the perception of tinnitus.

The goal of this trial to see if repetitive transcranial magnetic stimulation (rTMS) to the hearing area of the brain can lessen the perception of tinnitus. rTMS uses a strong magnet and when placed against the scalp generates a small electrical field within the brain. Depending on the frequency of the stimulation, this electrical field can either decrease or increase the electrical excitability of the brain. In this study, low-frequency stimulation will be used, which is thought to decrease...

Study increased the duration of rTMS from 2 to 4 weeks. The increase did not improve the procedure's efficacy. Below is the authors' conclusion:

Daily low-frequency active rTMS to the left temporoparietal junction area for 4 weeks was no more effective than sham for patients with chronic bothersome tinnitus. Possible explanations for this negative study include the failure of rTMS to stimulate deeper parts of auditory cortex within the sylvian fissure and more widespread cortical network changes not amenable to localized rTMS effects.​
