项目摘要

Through the project, a suite of benchmark problems has been established on the world wide web site to allow the mutual comparison of computational accuracy and efficiency of various methods on acoustics, i.e. finite difference method, finite element method, boundary element method, and so on.In 2003 financial year, as the first stage of the project, the platform were designed to consist of 25 problems that are classified into three-categories, "A.exterior," "B.interior" and "C.structural," with two domains, "frequency" and "time." Additionally, "Task" is also available to make further expansion easier. With the workstations that provide organized computational environments for the project members, several trial computations were carried out to give comparable data as to be contents of the platform. The outline of the activity and results of the project were summarized and submitted as papers to international conferences, ICA and RADS, to be held in spring 2004.Then, in 2004 financial year, further computations on the 10 problems were carried out and several problems were refined. Contents, i.e. computed results in downloadable Excel-format files, were also added and refined to make the platform useful. At the end of the financial year, European professors, P.Svensson and S.Marburg, were invited and a symposium on the project was held to discuss about both the project and computational acoustics.Finally, in 2005 financial year, transient analysis, interior problem in a convention hall and interior problem in a regularly shaped reverberation room, were examined and added as to be included in the benchmark problems. Then, a forum was held on the project, and at the forum five presentations were given by people from various companies, i.e. electrical, consulting, general contractor and soft-wear, to discuss about the availability of computational acoustics in their field works.

通过该项目，在万维网网站上建立了一套基准问题，以允许对各种声学方法的计算准确性和各种方法的效率相互比较，即有限差异方法，有限元方法，边界元素方法，边界元素方法，等等。在2003年，2003财政年度，作为项目的第一个阶段，该平台由25个问题组成。 “结构性”，具有两个域，“频率”和“时间”。此外，“任务”也可以使进一步的扩展更加容易。通过为项目成员提供有组织的计算环境的工作站，进行了几项试验计算，以提供可比较的数据，以作为平台的内容。该项目的活动和结果的概述总结并提交为国际会议，ICA和RAD的论文，将于2004年春季举行。到2004财政年度，对10个问题进行了进一步的计算，并进行了一些问题。还添加了内容，即在可下载的excel-format文件中进行的内容，并添加了完善的内容，并改进了该平台有用。 At the end of the financial year, European professors, P.Svensson and S.Marburg, were invited and a symposium on the project was held to discuss about both the project and computational acoustics.Finally, in 2005 financial year, transient analysis, interior problem in a convention hall and interior problem in a regularly shaped reverberation room, were examined and added as to be included in the benchmark problems.然后，在该项目上举行了一个论坛，在论坛上，来自各种公司的人们（即电气，咨询，总承包商和软件）进行了五个演讲，以讨论其现场工作中计算声学的可用性。
