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.

First Claim:
Show all 47 claims
We claim:     1. A method of realistically simulating a specified physiological and psychological sensation relating to physical movement associated with low frequency impact and shock wave phenomena, in an audience viewing a visual display in of such phenomena within a theater space, said method comprising the steps of:
  • generating a band of simultaneously present frequency spectrum components including random frequencies and transients having simultaneous plural 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 within said theater space, to provide acoustical output including said random frequencies and transients, at sufficient power levels to induce in the theater audience the specified sensation in the audience of substantial physical movement corresponding to low frequency impact and shock wave phenomena.
