Overview
Brief Summary
Objective Tinnitus is one of the most common acoustic disorders by affecting 5-43% people around the world, and tinnitus is harmful to social and individuals, inducing to annoyance, irritability, anxiety, depression, insomnia and concentration difficulties. Many efforts have been made to help tinnitus suffers, however, the curative means are still in absence. This study aims to introduce a novel sound therapy for tinnitus and to evaluate the efficacy of modified tinnitus relieving sound treatment in comparison with unmodified music which served as a control.
Methods and analysis A randomized, triple-blinded, controlled, clinical trial will be carried out. 68 patients with subjective tinnitus will be recruited and randomized into two groups in 1:1 ratio. The primary outcomes will be Tinnitus Handicapped Inventory (THI), Hospital Anxiety and Distress Scale (HADS), and visual analogue scale (VAS) for tinnitus; the secondary outcome measures will be Athens Insomnia Scale (AIS), tinnitus loudness matched by sensation level (LM, SL), and minimum masking level (MML). Assessment will be performed at baseline and at 1, 3, 9, and 12 months post-randomization. The sound stimulus will be persistent until 9 months after randomization, and be interdictory in the last three months.

Outcomes
Primary Outcomes
Tinnitus Handicapped Inventory (THI)
Time Frame: 12 months from baseline
THI is a self-assessment inventory including 25 items with grades four categories of tinnitus severity: slight corresponding to a score 0-16, mild (18-36), moderate (38-56), severe (58-100). The higher the score the more severe the tinnitus.
Hospital Anxiety and Distress Scale (HADS)
Time Frame: 12 months from baseline
HADS includes two subscales for anxiety and depression, each with respective 7 items, and the grades are valued by scoring: negative (0-7), positive (8-21).
Visual Analogue Scale (VAS) for tinnitus
Time Frame: 12 months from baseline
Visual Analogue Scale (VAS) for tinnitus is a universal psychometric scale evaluating subjective tinnintus. A total score is 10, from 0 to 10. The higher the score, the more severe the symptom.
Secondary Outcomes
- Athens Insomnia Scale (AIS)(12 months from baseline)
- tinnitus loudness matched by sensation level (LM, SL)(12 months from baseline)
- minimum masking level (MML)(12 months from baseline)
