How does the cinema reasonably arrange the cinema chairs according to the design?
The layout of the cinema should make full use of the existing limited space to reasonably arrange the cinema chairs, and set up as many cinemas as possible under the conditions of the cinema. Generally, it can be set to three types: large, medium and small halls. The giant screen hall can be set up with about 500 seats, and the small hall is suitable for about 80 to 100 seats. With the change of the show cycle and the number of audiences, it can be switched freely to make full use of the seats in the theater.
Design layout: Generally, a rectangle should be used. This layout is relatively simple for multi-hall arrangement, occupies less area, and distributes sound energy more uniformly. The aspect ratio of the theater must be strictly controlled at 1.5±0.2, otherwise the projection process design will be extremely limited.
Screen: Most modern movie audiences pursue the visual experience of a large field of view. The bigger the screen, the better, bringing more visual impact to the audience. In a sense, the size of the screen determines the technological conditions of the theater. Because in a movie hall with a determined size and volume, the closest viewing distance and viewpoint height can be calculated only after the screen size is determined; the luminous flux of the projector and the xenon lamp can be calculated from the screen size, average brightness, reflection system and projection distance. Power, can be used for stereo sound field design.
Starting from the slope: According to the star rating standard issued by the film quality inspection, the standard stipulates that the super-high value of the line of sight should not be less than 300px, so as to realize the design without blocking the line of sight. This requirement is very important. In actual design, the ideal line-of-sight ultra-high value should be determined according to the height of the first-row line-of-sight extension line of the screen. If the building conditions permit, the average line of sight super value should not be less than 375px, and it can be designed as a stepped floor with a rising trend from the front row to the back row, which is of great benefit to directly improving the visual and auditory conditions of the audience. Not only is the whole audience completely unobstructed, it is easier for the audience to directly obtain the direct sound of the main channel, but also the volume of the auditorium is reduced. Especially in multiplex cinemas, the space left by the raised ground in the rear area of several parallel auditoriums can also be used as public places (lounge, coffee shop, canteen, aisle, etc.) to increase the commercial area of the cinema.
Row spacing: The width of the row spacing not only affects the comfort of the audience watching movies, but also is very important for the audience's walking and evacuation. At present, there are two types of seats used in cinemas: flip-up and fixed. Flip-up seats are used. It is more appropriate to set the row spacing at 1.00m~1.10m. The fixed seat row spacing should be 1.15m~1.25m. ,The comfort of the fixed seat is better than that of the flip-up seat. No matter the full or empty field has little effect on the reverberation time of the auditorium, the qualified theaters choose high-end fixed seats, which is not only conducive to the improvement of the sound quality of the theater , but also to further improve the grade of the theater.
In addition, it should also be noted that the fabric of the seat should be made of flame retardant materials. Leather ones are generally used in VIP theaters, and there are remote control seat backs for calling services. The comfort and durability of other relatively cheap knitting, flannel, etc. are almost meaningless, and the market price ranges from 400-800 yuan. Others such as sound insulation materials and steel, including carpets, sound insulation cotton, sound insulation bricks, dragon backs, steel frames, etc., need to be selected independently according to the budget and size of the theater
