Promising sound therapy trial for ringing ears pulled before it began
NCT ID NCT07302373
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aimed to test a closed-loop sound therapy for people with chronic tinnitus (ringing in the ears) or hyperacusis (sensitivity to sound). The therapy was designed to retrain the brain's response to sounds. However, the trial was withdrawn before any participants were enrolled, so no results are available.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Sound therapy (closed-loop and placebo)
- What this could lead to
- If it had worked, this could have pointed toward a new sound-based treatment to reduce tinnitus and sound sensitivity.
- What could go wrong
- The trial was withdrawn before enrolling anyone, so we have no data on whether the therapy is safe or effective. It remains an early idea with no proof yet.
