Dynamical Acoustic Analysis over the Western Churches and Opera Houses

西方的大教堂，包括大教堂，歌剧院，包括拜罗伊特音乐节的测量和评估与新发展的原则和方法。3-在日本国内，作为对国外的准备，东大寺还在1998年建成了一座大型的“东大寺”，（Nigatsudo）东京新国家剧院和其他建筑物在相同的条件下进行测量，以分析声学特性之间的关系，例如语言清晰度或氛围，第一次用坚实的物理测量清楚地显示了仪式的时空设计。声源的垂直变化，如和尚的声音，在建筑声学中从未考虑过。我们已经开发了一个6通道的语音测量仪，并研究了动态，发现声音/声音从上有更多的氛围，这给听众的印象很大的影响。

Western Cathedrals including Luxemburger Dom, and Opera Houses including Bayreuther Festspielhaus are measured and evaluated with newly developed principles and methods. 3-dimensional spatial arrangement of speakers and singers, and their vocal divergences are directry evaluated and their dinamical isotropies are revealed.Also within Japan, as preparation for those in abroad, Todaiji Temple(Nigatsudo)New National Theater Tokyo and other buildings are measured with same condition for the analysis and relationship between acoustic characteristics e.g. verbal clarity or ambiance, and space-temporal design of the rituals are clearly shown with steadfast physical measurement for the first time.Vertical change of sound source, e.g. monk's voice, has never taken into account within architectural acoustics. We have developed a 6-channel correlomater and investigated the dynamics, and found the voice/sound from upward has much more ambience which gives much influence on listeners' impression.
