The Acoustic Design Of Multi-purpose Hall And Research Of Coupled Space

Multi-purpose hall buildings adapts to the development of China’s stage because of itsdiverse using function, higher utilization and lower operating costs. With the advancement ofsociety, people appreciate the level of improvement and development of the cultural market,the construction of such buildings will be more and more. Multi-purpose hall can besubdivided into theater-type and music type. But no matter how to minute, its design andconstruction should be focus on solving the fusion of architecture and sound design, thepeople pay more attention to the sound design.Therefore, it is important to do research thesound design of multi-purpose hall buildings.Found the coupled space, bring new ideas to the acoustics workers in the sound design ofmulti-purpose hall building. Coupled space what exists in the hall has a special acousticproperties. These features can significantly improve the sound quality and adjust the indoor.Acoustic properties of coupled space as a new technique which to adjust the sound quality ofindoor has a huge market prospects, is also a new trend of adjustable reverb design. So thestudy of the acoustic properties of coupled space have very importance significance.The thesis can be divided into three parts. First, with previous experience in themulti-purpose hall building summed up the general design principles and methods, anddescribes some structural measures how to design adjustable reverberation, and elicit theconcept of Coupled space, use it as a means of multi-purpose hall sound design. Thenresearch the acoustic properties of coupled space, and introduce different acoustic phenomenaof coupled space when open or closed, summarized some of its factors, such as the volume ofcoupled space,the area of the openings, the location where coupled space in the hall, etc.Changed these factors will affect the quality of the sound conditions of the hall. The last partis a introduction about a multi-functional theater building the introduction acoustic designof Weinan Theatre, then measure and analysis the coupled space appeared on the theater aboutits architectural acoustics, conclude the part of the acoustic properties of the coupling space.In addition, the software Odeon used to simulate the acoustic environment Weinan Theatre,comparison of the results of acoustic design. Looking for the optimal design of multi-purposehall architectural when it use the theory of coupled space.
