Vocal Toning & Vagal Humming Lab: Polyvagal Sound Stimulation

Framework: Polyvagal Phonation Research & Vagus Nerve Anatomy · 100% Private & Free

Stimulate your vagus nerve through mechanical pharyngeal vibration and extended exhalation humming. Proven to elevate Heart Rate Variability (HRV).

Scientific Overview

The vagus nerve passes directly adjacent to the vocal cords and pharynx. Low-frequency humming and vocal toning mechanically stimulate vagal fibers, triggering an immediate parasympathetic response.
