In this experiment, patients with chronic pure tone tinnitus were divided into three groups to receive auditory stimulation, somatosensory stimulation, vestibular stimulation and combined stimulation, in order to find an effective way to treat tinnitus
120 patients with chronic pure tone tinnitus over 6 months were randomly divided into 6 groups, one group was given auditory stimulation, one group was given somatosensory stimulation, one group was given auditory stimulation + somatosensory stimulation, one group was given auditory stimulation + vestibular stimulation, the last group was given auditory stimulation + somatosensory stimulation + vestibular stimulation.

The patients were recruited to record their medical history, and the hearing level, tinnitus indicators, vestibular function and tinnitus disability indicators were tested. Then the patients were randomly divided into six groups. They received the corresponding stimulation 20 minutes a day, 5 days a week for 3 weeks. After the last stimulation, the above tests were repeated immediately, one week later and three months later.

Electrical audiometry and acoustic impedance
Assessment of hearing in patients
Time frame: Three months from the time the patient was selected to the end of the stimulus
Tinnitus frequency and loudness
Detection of tinnitus frequency and loudness in patients
Time frame: Three months from the time the patient was selected to the end of the stimulus
Tinnitus disability scale
Tinnitus handicap inventory score was used to detect the degree of tinnitus.0-16 points without disability, 18-36 points with mild disability, 38-56 points with moderate disability and 58-100 points with severe disability. The 95% confidence interval is 20 points, that is, the difference between the two tests before and after the experiment is greater than or equal to 20 points.
Time frame: Three months from the time the patient was selected to the end of the stimulus
