Trans-Horizon Delivery — Over-Sea RF Link → 40 kHz Parametric Array → Physio-Acoustic Coupling
End-to-end architecture spanning 1 km to 1000+ km over land and sea: an over-the-horizon RF data link (marine microwave, HF skywave, or L-band satellite) carries compressed audio to a remote node that regenerates it as a localized 40 kHz parametric ultrasonic beam, self-demodulating in air into a 30–75 Hz physio-acoustic tactile wave. Two domains, one signal path.

If any of this frightens you: this site documents what signal physics makes possible in a laboratory, which is not evidence about what is happening to any individual. If you feel watched, targeted or unsafe, that distress is real and treatable.
