Study Summary

Primary Outcome
The Tinnitus Handicap Inventory (THI) is a 25-item questionnaire to assess how tinnitus affects an individual's life. Each question is responded to as 'yes' (4 points); 'sometimes' (2 points) or 'no' (0 points). The individual scores for the 25 questions are added to get a total THI score from 0 to 100. The higher the total THI score, the greater the negative impact tinnitus has on the individual's life. Change in total THI score is calculated as total THI score after the one week procedure admi
