- Efficacy: Change in Patient-reported Tinnitus Loudness Questionnaire (TLQ) Improvement From Baseline to Follow up Visit 3 (FUV3) [ Time Frame: Screening (D-14) versus final follow-up (D83) ]
Starting at the screening visit (SV), each subject recorded the following numerical rating scales (NRS) throughout the entire study duration:
- Tinnitus loudness "at its loudest" within the last 24 hours (Tinnitus Loudness Questionnaire [TLQ] NRSLoudest). Subjects were asked "On a scale from 0 to 10, where 0 represents no tinnitus and 10 represents extremely loud tinnitus, what one number best describes your tinnitus at its loudest in the last 24 hours (including right now)?" TLQ NRSLoudest was collected from SV (D-14) to the evening before FUV3 (D83). The ratings were to be recorded every day before going to sleep on an electronic device.
As Baseline the10 ratings of the screening period before the first treatment were averaged. For the FUV3 endpoint, the ratings of the 7 days before FUV3 were averaged.
- Co-Primary Efficacy: Improvement in Tinnitus Functional Index (TFI) Total Score From Baseline to FUV3 [ Time Frame: D0 (=TV1) versus Day 84 (=FUV3) ]
The TFI was recorded on an electronic device (electronic patient reported outcome) at Treatment Visit 1 (TV1), before randomization, and at Follow up Visit 1 (FUV1), FUV2 and FUV3.
The TFI is a patient reported outcome questionnaire and contains 25 questions. It includes eight subscales: Intrusive, Sense of Control, Cognitive, Sleep, Auditory, Relaxation, Quality of Life, and Emotional. Each question is to be rated on a NRS between 0 and 10 (or 0 to 100%), with a recall period of "over the past week".
The TFI total score is considered as valid if there are evaluable answers for at least 19 of the 25 items (76% of items) (Meikle et al. 2012). The repondent's overall TFI score is within a 0-100 range. For the subscales the range is the same. A lower value represents an improvement for all scales.

- Safety: Frequency of Subjects With Deterioration of Hearing at Follow up Visit 2 (FUV2) [ Time Frame: Day 35 ]
Occurence of deterioration of hearing (Air and Bone conduction) in the treated ear at FUV2.
Deterioration is defined as a deterioration of hearing threshold of at least 15 dB from Baseline at the average of 2 contiguous frequencies.
