Note: For the treatment assessments, only those patients who reported significant outcome in the last assessment were followed up. Post-i: immediately after intervention, post-1h: at one hour post intervention; post-1w: at one week post intervention; post-1m: at one month post intervention. Tinnitus loudness and distress ranged 0–10 where 0 indicates the lowest level and 10 indicates the highest tolerable level.
