Vibroacoustic Map
Low frequency sound (30Hz - 120Hz) delivered directly to the body via transducers can stimulate the afferent vagus nerve, increasing Heart Rate Variability.
Clinical Protocols
| Frequency (Hz) | Primary Target | Application |
|---|---|---|
| 30 - 40 Hz | Musculoskeletal | Spasms, lower back tension. Applied via bed/mat. |
| 40 - 68 Hz | Neurological | Parkinson's rigidity protocols (esp. 40Hz). |
| 80 - 120 Hz | Pulmonary / Vagal | Applied near sternum. Stimulates vagal tone. |
Hardware Requirements
Standard headphones cannot deliver vibroacoustic therapy. You must use a tactile transducer (bass shaker) bolted to furniture, or a specialized VAT mat. The SPL should be high enough to cause physical vibration without exceeding 80dB of audible sound.
