Sound therapy: a 9-Minute fix for anxiety and stress?
NCT ID NCT07561515
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether listening to specific sound frequencies for just 9 minutes a week can improve mental health. 110 adults with mild anxiety, stress, or depression will either sit in a special sound chamber or use headphones. The goal is to see if this simple, drug-free approach can reduce symptoms and boost quality of life.
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 (specific frequencies played through an acoustic resonance chamber or headphones)
- What this could lead to
- If it works, this could offer a simple, non-drug way to reduce anxiety, stress, and depression symptoms.
- What could go wrong
- This is a small, early-stage trial with only 110 participants and no blinding, so results may not be reliable or generalizable. The effect may be no better than a placebo.
