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

本研究的目的是：◇掌握音响和演奏器的孔洞可变区的作用。◇确定了音乐厅活动部件设置的指导原则，◇通过演示实验，掌握了与特征活动部件设置条件有关的声学特性。◇提取了问题，收集并积累了进一步的基础数据，为以后的检查积累了基础数据，同时指出了未来的问题。通过本研究判断，可变天花板的构造条件可能是由音乐家决定的，声学特性是通过演示实验来决定的。在日本音乐、声乐、音乐特别选择了概念不同的条件，并适当地在乐曲和演奏者的条件中使用。

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.
