FREQUENCY ANALYSIS — 19 Hz INFRASOUND ANOMALY
In 1998, researcher Vic Tandy of Coventry University published findings on the effects of 18.98 Hz infrasound on human perception. The frequency, generated by a faulty ventilation fan in his laboratory, produced consistent reports of peripheral visual disturbances, feelings of unease, and the sensation of a presence in the room.
Tandy's research was subsequently referenced in
The frequency 18.98 Hz corresponds to the resonant frequency of the human eyeball. At sufficient amplitude, this frequency causes the vitreous humor to vibrate, producing visual artifacts in peripheral vision that the brain interprets as movement or shadowy figures.
CLASSIFICATION NOTE: This frequency has been independently identified in three Fragment Zero investigations. Its presence in the Somnus haptic catalog (Pattern S-031) suggests deliberate weaponization of a naturally occurring perceptual vulnerability.
Current deployment status of S-031 across consumer devices:
Tandy's original paper, 'The Ghost in the Machine,' was published in the Journal of the Society for Psychical Research, Vol. 62, No. 851. The paper has been cited 340 times. None of the citing papers are from the consumer electronics industry. Officially.
