Airscreen
An inflatable movie screen is an inflatable framework with an attached projection screen. Inflatable screens are used for outdoor movies, film festivals, drive-in theaters, sports, social, fundraising and other events requiring outdoor projection. Design The projection frame is made from PVC-coated fabric layers joined by high-frequency welding or mechanical sewing. The projection surface can be made of PVC or spandex, with the latter providing for rear projection capabilities. The projection surface can be detachable for ease of care. The frame is inflated with a high-pressure air blower. Larger frames may require a three-phase blower. For bigger screens, the blower typically continues to operate, ensuring the screen remains fully inflated. With some brands, screen sizes up to 7m or 24ft width do not require a constantly operating air blower. Screens can be held upright with help of a supporting structure (A-frame or inflatable legs) or with the system of straps and counte ...

Projection Screen
A projection screen is an installation consisting of a surface and a support structure used for displaying a projected image for the view of an audience. Projection screens may be permanently installed on a wall, as in a movie theater, mounted to or placed in a ceiling using a rollable projection surface that retracts into a casing (these can be motorized or manually operated), painted on a wall, or portable with tripod or floor rising models as in a office, conference room or other non-dedicated viewing space. Another popular type of portable screens are inflatable screens for outdoor movie screening (Outdoor cinema, open-air cinema). Uniformly white or grey screens are used almost exclusively as to avoid any discoloration to the image, while the most desired brightness of the screen depends on a number of variables, such as the low-key lighting, ambient light level and the luminous power of the image source. Flat or curved screens may be used depending on the optics used to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Outdoor Cinema
An outdoor cinema consists of a digital or analog movie projector, scaffolded construction or inflatable movie screen, and sound system. History In the summer of 1900, in Syntagma square, Athens, films were projected outdoors, in the cafés. Around 1916, outdoor cinemas first arrived in Berlin, Germany. During the 1920s, many "rooftop theatres" converted to cinema use. One example of this was the Loew's New York, located on Times Square. In 1951, National Theater (Manhattan) rooftop theatre re-opened as a cinema. Viewers usually sit on camping chairs or blankets. Some Hollywood world premieres were screened in outdoor cinemas – sometimes with the stars in attendance. Most screenings are free with some raising money for charities. As projector prices have decreased, guerrilla style outdoor cinemas have become more common. These are run on a very small budget by groups of amateurs. The events commonly are organised online; participants then meet in parks, empty parking l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Festival
A film festival is an organized, extended presentation of films in one or more movie theater, cinemas or screening venues, usually annually and in a single city or region. Some film festivals show films outdoors or online. Films may be of recent date and depending upon the festival's focus, can include international and/or domestic releases. Some film festivals focus on a specific format of film, such Documentary film, documentary, or runtime, such as short film festivals, or genre, such as horror films, category of filmmakers, such as Woman, women, production country/region or subject matter. Film festivals can be competitive or non-competitive, and are often regarded within the film industry as launchpads for new filmmakers and indie films, as well as boosters for established filmmakers and studio productions. The films are either invited by festival curators, or selected by festival programmers from submissions made by the filmmakers, film producers, production companies, sale ...

Drive-in Theater
A drive-in theater/theatre or drive-in cinema is a form of movie theater, cinema structure consisting of a large outdoor movie screen, a projection booth, a concession stand, and a large parking area for automobiles. Within this enclosed area, customers can view movies from the privacy and comfort of their cars. Some drive-ins have small playgrounds for children and a few picnic tables or benches. The screen can be as simple as a painted white wall, or it can be a steel truss, truss structure with a complex finish. Originally, the movie's Sound recording and reproduction, sound was provided by Loudspeaker, speakers on the screen and later by individual speakers hung from the window of each car, which was attached to a small pole by a wire. These speaker systems were superseded by the more practical method of microbroadcasting the soundtrack to car radios. This also has two advantages: 1. the film soundtrack to be heard in stereophonic sound, stereo on car stereo systems, which ar ...

Polyvinyl Chloride
Polyvinyl chloride (alternatively: poly(vinyl chloride), colloquial: vinyl or polyvinyl; abbreviated: PVC) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year. PVC comes in rigid (sometimes abbreviated as RPVC) and flexible forms. Rigid PVC is used in construction for pipes, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards. Adding plasticizers makes PVC softer and more flexible. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products, and in rubber substitutes. With cotton or linen, it is used in the production of canvas. Polyvinyl chloride is a white, brittle solid. It is soluble in ketones, chlorinated solvents, dimethylformamide, THF and DMAc. Discovery PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noise Cancelling
Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in commercial airline headsets with the technology becoming available in the late 1980s. The technology is also used in road vehicles, mobile telephones, earbuds, and headphones. Explanation Sound is a pressure wave, which consists of alternating periods of compression and rarefaction. A noise-cancellation speaker emits a sound wave with the same amplitude but with an inverted phase (also known as antiphase) relative to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out – an effect which is called destructive interference. Modern active noise control is generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noise Control
Noise control or noise mitigation is a set of strategies to reduce noise pollution or to reduce the impact of that noise, whether outdoors or indoors. Overview The main areas of noise mitigation or abatement are: transportation noise control, architecture, architectural design, urban planning through zoning codes, and industrial noise, occupational noise control. Roadway noise and aircraft noise are the most pervasive sources of environmental noise. Social activities may generate noise levels that consistently affect the health of populations residing in or occupying areas, both indoor and outdoor, near entertainment venues that feature amplified sounds and music that present significant challenges for effective noise mitigation strategies. Multiple techniques have been developed to address interior sound levels, many of which are encouraged by local building codes. In the best case of project designs, planners are encouraged to work with design engineers to examine trade-offs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
