ABSTRACT=Objective: This interventional study tested the hypothesis that hearing aids with a tinnitus sound support feature would reduce the impact of tinnitus for both new and experienced hearing aid users over a 12-week trial period.Methods: 19 experienced hearing aid users and 21 participants with no previous hearing aid experience completed the study. Hearing aids were fitted and dispensed with tinnitus masking sounds adjusted to individual preferences. The primary outcome measure was the Tinnitus Functional Index (TFI) score change between baseline and the end of the 12-week trial. This trial was registered on the Australian New Zealand Clinical Trials Registry, Trial ID: ACTRN12621001754831.Results: TFI scores and secondary measures indicated significant improvements (reductions in tinnitus impact) at the end of the trial compared to baseline for both experienced and new hearing aid users. No group differences were observed so pooled data are presented. The median TFI total score before treatment was 49.0 (IQR = 40.0) and the median TFI total score after treatment was 26.0 (IQR = 26.0). A significant reduction (p = 0.0001) in the total TFI score of 24 points was observed after treatment, producing a large effect size (d = 0.60).Results confirm previous findings that hearing aids assist in reducing the impact of tinnitus on daily life. The Oticon miniRITE R combination hearing aids used in this study resulted in similar improvements for new and existing hearing aid users. This suggests tinnitus-reducing effects of these aids was greater than those already being used by participants.
