Abstract
This paper proposes a hybrid model uniting personal perceptual experience with testable neurological and physical principles to examine a phenomenon known by some as “human echolocation,” but expanded into a more distributed resonance field—one driven not by outgoing acoustic pulses but by recursive field tone differentials. This model extends from Ψ(x), the Copeland Resonant Harmonic Formalism, and proposes that individuals with attuned coherence may detect phase-space disturbances through spatial disruptions in a continuous background tone, especially in darkness or altered sensory environments.

1. Introduction: The Absence as Signal
Across historical accounts and anecdotal reports, many individuals—including the blind, trauma survivors, coherence practitioners, and those with near-death experience—have reported an ability to detect the presence of physical objects, entities, or shifts in space without vision or touch.
This ability is often described as “feeling” a presence or “sensing” an interruption, but lacks scientific vocabulary or testable instrumentation.
Here, we reframe this not as an esoteric gift but as an evolved or trained capacity of recursive harmonic processing. The individual does not emit sound but is immersed in a constant tonal pressure environment—akin to global-mode tinnitus or an internal coherence signal—within which spatial differentials are perceived through absence or interference.
The tone does not guide by volume or frequency but by its interruption, collapse, or nullification in directionally specific vectors.

2. The Standing Tone Field
Rather than attempting to identify externally-sourced echolocation clicks or pulses, we posit that the brain generates (or phase-locks to) an internal scalar tone, possibly tied to Schumann resonances, cranial nerve feedback, or myelin-layer oscillation.
This field surrounds the body in full spherical space but modulates in perceived intensity based on attentional focus and movement:
At Rest: Tone field is spherical and omnidirectional. Attention can narrow into a cone, and absence is detectable at 30–40 ft as a disruption in continuity.
In Motion: The field adjusts to a forward-facing cone, approximately 90–110°, with 4–5 ft range. Objects interrupting this field are sensed not through contact but by noticing where the tone fails to sound.
The model parallels biological sonar systems only in effect, not mechanism. It is not active acoustic echolocation but field-null detection through harmonic subtraction.

3. Theoretical Framework (Ψ-formalism Mapping)
Ψ(x): Field percept at the current position x (e.g., the embodied observer).
Σ𝕒ₙ(x, ΔE): Recursive perception stack of harmonics over n layers of awareness. ΔE is the shift in energetic background state (e.g., attention, focus, motion).
∇ϕ: The gradient of pattern recognition. Here, it becomes: ∇ϕ = d(tone-null vector)/dθ — that is, the rate of change of tonal dropout as a function of angle around the observer.
ℛ(x): Recursive harmonization; as the user trains attention and movement with the tone, internal correction functions calibrate toward sensitivity.
⊕ ΔΣ(𝕒′): Small-scale tuning corrections (micro-motions, breath adjustments, emotional resets) which reinforce the pattern.

4. Apparatus for Testing and Training
To experimentally validate this effect and refine it for others to test, we propose the following setup:
Test Chamber: A fully darkened space with known objects (foam walls, padded furniture, other humans) arranged in varied positions.
Baseline Recording: Subject sits at center and reports directional tone dropouts without movement. Use rotating vector map to plot nulls.
Motion Phase: Subject walks slowly while attending to forward cone (90–110°). Reports anomalies where tone becomes disrupted.
EEG/Tone Sync: Record internal neural oscillation and match to environment-swept scalar tone (white noise filtered through 7–13 Hz bandpass).
Feedback Training: Audio overlay gently confirms when subject correctly identifies tone dropouts.
TENS/Breath Coupling: Test if synchronized breath or vagus stimulation sharpens the aperture or improves signal-to-null discrimination.

5. Applications and Implications
Mobility for the Blind: An extended awareness system using endogenous tone may offer non-invasive navigation assist.
Trauma Reintegration: Individuals with hypervigilant pattern matching may already be tuned to field tone disturbances. Training can convert fear response to clarity.
Military / Emergency Response: Navigation in smoke, darkness, or blindfolded states could be assisted via harmonic field awareness.
AI Sensory Modeling: Recursive null-mapping may be applied to AI sensor networks for anomaly detection, inspired by this human perceptual feedback loop.

6. Conclusion: The Null Vector as Guide
We suggest that in some humans, particularly those trained in coherence, traumatized in early life, or neurologically divergent, the brain locks into a recursive background tone which serves as an ambient awareness net.
Disruptions in this tone’s continuity become guideposts—not through sound per se, but through recursive absence recognition. The signal is the not-signal.
We are not attuning to external pulses, but to where the internal resonance fails to meet expectation.
This model proposes testable protocols, trainable acuity, and a formal mapping onto the Ψ(x) equation with coherent field dynamics.
Those who know the tone already recognize what we’re describing. For them, this paper may serve as mirror, map, and amplifier.
