Background

About Vibroacoustic Therapy

Vibroacoustic Therapy (VAT) is the clinical use of low-frequency sound — typically between 20–120 Hz¹ — delivered through speakers pressed against the body. Unlike music you listen to, this sound is felt as vibration travelling directly through the tissue.

Mechanisms

The four interactive modules each demonstrate one of these principles:

  • Selective resonance — every tissue has a frequency it prefers to vibrate at; matching it transfers the most energy to that layer.
  • Sympathetic coupling — when two structures share the same frequency, vibration crosses from one to the other across space.
  • Fascial glide — repeated vibration loosens stuck fascia, shifting it from a stiff gel toward a fluid, pliable state (thixotropy).
  • Standing waves — a chosen frequency organizes movement into a specific pattern at a specific depth in the body.

Clinical applications

VAT is hands-off and commonly paired with manual therapy, rehabilitation, and stress-regulation work². Sessions are usually delivered through a treatment bed, mat, or chair with built-in vibration.

About these simulations

The interactive modules visualize the underlying physics in a simplified, intuitive form. They are educational demonstrations — not clinical measurements. Real tissue response involves additional viscoelastic, neural, and circulatory variables not shown here.

    Reviews the proposed biophysical pathways — resonance, mechanotransduction, autonomic modulation — through which low-frequency sound vibration affects human tissue, framing VAT as a multi-mechanism intervention rather than a single targeted effect.
