Various "sound sources" used in the scene of education, research and business on architectural acoustics were collected. They were prepared as a digital database, which can be easily processed and used by users. The number of collected sounds is 903 (about 9.3 GB), and the file format of them is WAV. They are generally classified into four types as follows : 1) recorded sounds in the actual spot of the sound, 2) dry sources (recorded in anechoic rooms), 3) impulse response (measured in concert halls etc.), 4) artificially-reproduced impulse responses (transferred from the measured values of transmission loss of material, etc.). Some application examples of this database, called "Menu", are also presented. This aims to be applied to not only the lesson of the department of architecture of a university and a technical college but also the skill on architectural acoustics for designers and engineers of architecture. Also, general users can use this database as a library of sounds. Furthermore, the software for processing the sound sources was newly developed. The functions to add two sounds, to compare two sounds by hearing and to convolute the dry source sound with an impulse response are equipped in it. The sounds are as a rule played by the personal computer. Therefore, the program for checking the performance and the setup of user's personal computer were also developed. The results of this research (collected sounds and newly-developed menu and software) facilitate the use of sounds in the scene of education, research and business on architectural acoustics. Moreover, measurements, tests and experiments by using the sound source in this database enable to compare the results under the same conditions, and consequently the result of this research will bring the standardization of sound sources for architectural acoustics.

收集了建筑声学教学、科研、商业等场景中使用的各种“声源”。它们是作为一个数字数据库编制的，用户可以很容易地处理和使用。收集的声音数量为903（约9.3 GB），文件格式为WAV。它们通常分为以下四种类型：1）在声音的实际位置记录的声音，2）干源（在消声室中记录），3）脉冲响应（在音乐霍尔斯等中测量），4)人工再现的脉冲响应（从材料的传输损耗的测量值等传递）。文中还介绍了该数据库“菜单”的一些应用实例。这不仅适用于大学和技术学院建筑系的课程，也适用于建筑设计师和工程师的建筑声学技能。此外，一般用户可以使用这个数据库作为一个图书馆的声音。此外，还新开发了处理声源的软件。它具有两种声音相加、两种声音听比较、干声源与脉冲响应卷积等功能，通常由个人计算机播放。因此，还开发了用于检查用户个人计算机的性能和设置的程序。本研究的成果（收集的声音和新开发的菜单和软件）促进了声音在建筑声学的教育，研究和商业场景中的使用。此外，利用该数据库中的声源进行测量、测试和实验，可以在相同条件下比较结果，因此，本研究的结果将带来建筑声学声源的标准化。
