The Study

Published in 2020 by Aravena et al., this randomized clinical trial investigated the effects of music frequency on anxiety during dental extractions.

Cortisol Levels (µg/dL)

Standard Tuning (440Hz)1.35 µg/dL
SoulTune Resonance (432Hz)0.49 µg/dL

Why It Matters

  • Biological Proof: This isn't just placebo. The chemical markers in saliva changed significantly.
  • Anxiety Reduction: Patients felt noticeably calmer without pharmaceutical intervention.
