"Barrier of Silence" Directed by Leon Benson Teleplay by : Lou Huston Original air date September 3, 1955 Professor Richard Sheldon has been returned to the United States in a confused, altered state of mind after enemy agents hypnotized him in an environment of absolute silence while visiting Milan. His friend, psychiatrist Dr. Elliott Harcourt, reasons that placing Professor Sheldon in a similar environment will reverse his condition. He is placed in a wheelchair in the "Cone of Silence", consisting of a raised circular platform suspended by 3 wires tied to a common vertex. Although the cone's surface is open, anyone sitting inside would experience silence due to the phased ultrasonic noise generators located just below the vertex. Anyone speaking inside the cone could not be heard outside. With Dr. Harcourt's guidance, the treatment works, and Sheldon regains his memory.
