Abstract Tinnitus is a symptom of sound perception in the absence of external sound stimulation, and most patients have unilateral tinnitus, with more tinnitus on the left than on the right. In this paper, the resting EEG data of 10 patients with binaural tinnitus, 10 patients with left tinnitus and 10 healthy controls were collected, and two 10-s segments of resting EEG data were intercepted from each group for approximately 10 min. The absolute and relative power was calculated by fast Fourier transform. The results showed that more frequency bands were significantly different in the left tinnitus patients compared to the bilateral tinnitus patients and the right tinnitus patients, and where significant differences were demonstrated, the absolute and relative power was higher in the Delta and Theta bands of the tinnitus patients than in the control group. In conclusion, these results compare the resting state EEG power spectrum abnormalities in patients with tinnitus on different sides with healthy controls from an electroencephalographic perspective, and are expected to be used as an evaluation criterion in the future to provide a more refined and precise treatment plan for patients with tinnitus on different sides and to improve the efficiency of treatment.
