This is a sculptural piece mounted on a pedestal and crowned with a series of sensors. The work actively intervenes in phone calls and audio recordings by jamming nearby microphones. It operates by emitting ultrasonic waves via integrated transducers — devices that convert energy from one form to another.

While these frequencies remain inaudible to the human ear, they disrupt the specific range microphones rely on, distorting any captured audio into an unrecognizable signal. The interference is hyper-localised, affecting only devices directly in front of the object while remaining completely unobtrusive to anyone else in the room. The title references Shoshana Zuboff’s concept of the “Big Other” — a systemic architecture that continuously monitors, tracks and evaluates human behaviour.

The piece poses a critical question: is this technology a vital shield for personal privacy, or a disruptive force that undermines established systems of security and accountability?
