Joint Study on Multimedia Database of Architectural Acoustics

从利用多媒体数据在课堂教学中激发学生对建筑声学的兴趣这一观点出发，构建建筑声学多媒体数据库，将教材的制作工作共享给包括海外工作人员在内的13名工作人员，根据每个工作人员在各自专业领域的经验和成就将广泛的建筑声学领域的最新信息录入数据库。该数据库的基本概念如下：(A)易于理解无形的声学现象，(B)尽可能具体，(C)设身处地为学生着想，(D)即使对学术能力不高的学生也很容易。该数据库以Microsoft的PowerPoint文件的形式在CD-ROM上提供，这是因为它具有易于使用的多媒体材料，如数字图像和声音。内容涵盖了物理声学、心理声学、房间声学、噪声标准、噪声评价、噪声控制、吸声、隔声、地板冲击噪声等建筑声学标准领域。该数据库包括英文版和考虑到外国学生的日文版。幻灯片的设计不仅使用了大字母和清晰的颜色，易于识别，而且使用了共同的颜色、原始标志和序列号，具有统一感。此外，Power Point中配备的电影和动态显示等动态呈现也得到了积极的应用。每位教师在使用这个数据库时，可以很容易地将幻灯片设置成适合自己讲课的内容，因为PowerPoint文件中的幻灯片非常容易修改、添加和替换。

From the point of view that taking advantage of multimedia data in a lecture could rouse students learning architecture to be interested in architectural acoustics, the object of this study is to construct the multimedia database on architectural acoustics.The works of producing educational materials is shared among thirteen staffs including overseas staffs to put the recent information on wide areas of architectural acoustics into the database, which is on the basis of each staffs experience and achievement in their special fields. The basic concept of the database was as follows : (a) easy to understand invisible acoustical phenomenon, (b) concrete as much as possible, (c) put ourselves in a student's place, (d) easy even for the students without a higher level of academic ability. The database is supplied as Microsoft's PowerPoint files on CD-ROM by making its advantage of easy use of multimedia materials such as digital images and sounds. The contents cover standard fields on architectural acoustics such as physical acoustics, psychological acoustics, room acoustics, noise standard, noise evaluation, noise control, sound absorption, sound insulation, and floor impact noise.A lot of original slides are designed which are not quoted from a standard textbook. The database includes English version as well as Japanese version considering foreign students. The slides are design not only to be easy to recognize by using a large letter and clear color but also to have a sense of uniform by using a common color, original logo and serial number. Moreover the dynamic presentation such as movies and dynamic show equipped in Power Point are aggressively applied. When each teacher use this database, he/she can set easily the slides to adopt his/her own lecture, because the slides in Power Point file is very easy to revise, add and replace.
