The Mouth-Open / Tongue-Out Posture Changes Sound & Consciousness
The Mouth-Open / Tongue-Out Posture Changes Sound & Consciousness
When you open the mouth wide and extend the tongue, you’re doing three things that directly change the acoustics and the nervous system:
A. It opens the pharyngeal cavity
This makes sound resonate not just forward but upward into the skull.
That’s why you felt:
“the sound seems more surrounding… heard in the top of the head”
Correct — this posture increases bone conduction, which makes the sound feel like it's coming from inside the skull.
B. It disengages normal speech control
Sticking the tongue out disrupts the “civilized”, precise speech mechanism and forces you into raw primal vocalization — closer to chanting, humming, or growling.
This can induce a trance-like or “surrounding” auditory feeling.
C. It activates parasympathetic tone
The tongue has major cranial nerve involvement (especially the vagus nerve).
Tongue extension can create:
-
slight vagal stimulation
-
relaxation + trance
-
altered auditory perception
This is why many yogic techniques use exaggerated tongue positions (like Khechari mudra, tongue to palate) to induce psychoacoustic shifts.
