Abstract:
1. A method of converting a multiplex theatre hall into an immersive motion picture theatre hall, comprising: a. providing a multiplex theatre hall having a left wall, a right wall, a front wall, and a rear wall and comprising: b. changing the set of loudspeakers so that it comprises at least five discrete loudspeakers and at least one sub-bass loudspeaker assembly, (i) a first discrete loudspeaker of the set of loudspeakers being positioned adjacent the left section of the second projection screen, (ii) a second discrete loudspeaker of the set of loudspeakers being positioned adjacent the center section of the second projection screen, (iii) a third discrete loudspeaker of the set of loudspeakers being positioned adjacent the right section of the second projection screen, (iv) a fourth discrete loudspeaker of the set of loudspeakers being positioned adjacent the left and front walls, and (v) a fifth discrete loudspeaker of the set of loudspeakers being positioned adjacent the right and front walls, (vi) each of the at least five discrete loudspeakers receiving signals via a separate audio channel, and (vii) at least one of the loudspeakers of the set of loudspeakers being (A) located closer to the first patron seat location than to the second patron seat location and (B) configured to direct proportionally more sound energy to the second patron seat location than to the first patron seat location; c. aiming the at least five discrete loudspeakers so that patrons sitting at the first and second seat locations perceive sound from all audio channels as having essentially the same volume level and tonal quality; and d. projecting the image over a major portion of the second projection screen, increasing vertical field of view of the image for patrons sitting at the first and second seat locations, thereby creating an immersive motion picture theatre hall.
