BBC 4 “silent” test screen recording.
Subliminal test pattern. It is a repeat recording so the message gets reinforced with time. The repeat recording can be anything it wants to be depending on circumstances. Seasonal purchases. Voting Subliminals. Silent sound subways, unseen and undetected, coming in under the radar and into the mind taking advantage of the limitations of the hearing spectrum 20 hertz to 20 kilohertz: low infrasound to high-frequency tinnitus ultrasound all coming in at the edges of the hearing spectrum. So are your perceptions really your own.
