Mild 8 dB hearing amplification for tinnitus in adults with normal hearing
Official title: The Effect of Mild-gain Amplification on Tinnitus Perception in Normal Hearing Adults
Run by Technical University of Denmark · NCT07489807 · Data updated 2026-11-12
This test tries wearing hearing aids that add a small (8 dB) boost to see if they reduce tinnitus symptoms in adults with normal hearing.

Is this trial a fit for you?
✓Likely a good fit
Adults with chronic bothersome subjective tinnitus for at least three months, normal hearing thresholds (≤25 dB HL from 125 Hz to 8 kHz), and no prior hearing-aid experience are the ideal candidates.
✕Probably not a fit
People with objective or pulsatile tinnitus, Meniere's disease, a history of stapedectomy/stapedotomy/tympanoplasty, or hearing loss >25 dB HL are unlikely to benefit from this specific approach.

What this trial studies
This double-blinded crossover study enrolled 12 adults with chronic, bothersome tinnitus and normal audiograms to compare two hearing-aid settings delivered for three weeks each. One condition provided a mild 8 dB gain from 1 Hz to 8 kHz and the other provided no amplification as an active placebo. Outcomes included changes in tinnitus-related distress measured by the Tinnitus Functional Index (TFI) and ratings of tinnitus loudness and annoyance on visual analog scales (VAS). Participants were inexperienced hearing-aid users and were screened to exclude objective/pulsatile tinnitus and certain middle-ear disorders.
Why it matters
Potential benefit: If successful, mild-gain amplification via hearing aids could reduce tinnitus distress, perceived loudness, and annoyance for some adults with normal hearing.
How similar studies have gone: Hearing-aid amplification has shown benefit for tinnitus in people with hearing loss, but using a mild 8 dB gain in people with strictly normal hearing is less well studied and evidence is limited.

Deciding whether PTSD therapy or tinnitus therapy should come first for people with both conditions.
This project will try giving either PTSD therapy first then tinnitus therapy, or tinnitus therapy first then PTSD therapy, in veterans and active-duty adults with PTSD and bothersome chronic tinnitus to see which order helps more.
