Alien Mind Control Signal

A piercing electronic signal emitted within the alien spaceship's quarantine room, triggering a conditioned trance state in the Mars Probe 7 astronauts (Van Lyden, Michaels, and LeFee). The signal enforces their mental compliance, suppressing awareness of their captivity and preceding the alien's materialization. The Doctor reacts to the noise, which disrupts the false normalcy of the astronauts' activities (e.g., a football match) and enforces obedience during the escalating confrontation with the alien entity.
