Abstract:     A special effects system for simulating physical sensations in an audience during the presentation of a motion picture. Relatively high intensity, very low frequency random noise is acoustically coupled to a theater space to produce psychological and physiological sensations, much as earthquake movements, in the audience. The special effects are controlled by a control sub-channel which is either frequency multiplexed onto a conventional optical audio track or, in a magnetic stripe film format, the control sub-channel is placed on an accompanying optical track. The presence and amplitude of two control frequencies in the sub-channel are detected and logically combined, providing four separate digital function control signals and two analog control signals which are variable in amplitude.

We claim:     1. A method of simulating a specified physiological and psychological sensation in an audience viewing a visual display in a theater, said method comprising the steps of:
  • generating random frequencies and transients having components in at least the infrasonic frequency range; and
  • applying, in synchronism with said visual display, said frequencies and transients to acoustic transducers located in said theater, at sufficient power levels to induce the specified sensation in the audience.
