And then author summerized the result of subjective and objective assessment of that effect as follows:

With subjective assessment, excellent effective was 13.6% and effective was 40.9%.
On objective assessment with tinnitus test, 45.5% of all cases got 5∼10 dB ameliolation of tinnitus intensity, and 4.5% had 15 dB amelioration.
Side effect was seen in 13.6% of all patients with dizziness, nausea, nystagmus and headache or head heaviness, but they abolished within one minute.
