<qa>  What is the standard treatment in chronic tinnitus?Additionally, there is also evidence that high-frequency stimulation of the temporoparietal cortex is effective in chronic tinnitus. Furthermore, standard treatment in chronic tinnitus is two weeks ten treatment days which is shorter than the standard in rTMS in affective disorders. Thus, the aim of the present trial is to investigate the influence of high-frequency stimulation of the temporoparietal cortex and of increasing the number of treatment days.
