The problems of hole acoustic characteristic and listening in the SOUGAKUDO-Hall

本研究的目的在于：①掌握演奏声音和演奏者的演奏孔可变区的作用; ②确定演奏厅活动部件设置的指导原则; ③通过演示实验，掌握与特征活动部件设置条件相关的声学特性; ③提取问题，并进一步收集和积累了今后研究的基础数据，同时指出了今后的问题。本研究通过示范性实验，判断了音乐家决定可变顶棚的构造条件、声学特性的可能性。在日本音乐、声乐、特别地选择了其中概念分别不同的条件，此外，它将被适当地用于音乐作品和演奏者的条件。

This research has been advanced for the purpose of following fact.◇The effect of the hole variable region for musical performance sound and player is grasped.◇The guideline of the moving parts' setting in the Hall, to the practical use is decided.◇The acoustic characteristic which is related to the characteristic moving parts' setting condition by the demonstration experiment is grasped.◇The problem is extracted, and further basic data for future examination are collected and are accumulated, while future problem is indicated.It was possible that the construction condition of the variable ceiling was decided by musicians he judging in this study, acoustic characteristic through the demonstration experiment.In Japanese music, vocal music, the condition in which concepts respectively differed was specially chosen, and in addition, it would be used in musical piece and condition of the player properly.
