The Study On Control Of Multiplexcinema Noise

With the rapid development of China’s economic construction and people’s social and cultural life, the film became an integral part of people’s lives and leisure entertainment. Subsequent developments in recent decades, the theater began to show derived from a single spatial mode in a variety of ways, the emergence of multiplex cinema. With the impact to television as the representative of the emerging media appeared, small hall, multi-hall show mode into a preferred mode for the new cinema, the number of multi-hall cinema in the rapid growth of the city every year.Multiplex cinema as a major form of a new era of rapid development of cinema in the context of the times. With people viewing requirements has been improved, the market for multi-hall cinema sound environmental design put forward higher requirements. With perfect screening technology development and digital technology, more and more theater sound effects shock, provide a strong audience auditory impact, which requires relatively prominent theater sound effects, to avoid between auditorium and the outside world, video room mutual interference between the auditorium. Meanwhile, as people viewing comfort requirements continue to increase, of air conditioning equipment and other services in the growing proportion of the theater, noise and disturbance when they issued abatement work also becomes more important.In this paper the current mainstream multiplex cinema theater building type as the research object, by taking architectural acoustics theoretical research and engineering example of combining research and verification research methods, conduct research on behalf of the object, acoustic theory analysis, building envelope insulation design, air conditioning system noise design and engineering work and other aspects of verification examples. On control methods multiplex cinema design and construction noise present problems were studied by structural design and engineering data to measure and compare the reality to analyze and draw the appropriate conclusions and recommendations.We hope that through research and analysis and theoretical research in this paper, can provide some useful lessons for the prevention and treatment of multi-hall cinema construction and development of noise, to enhance multi-hall cinema sound environment to make some contribution.
