摘要
目前国内对非表演类中国传统建筑的声场特征仍缺乏研究,本文选择沈阳故宫博物院的3栋主要大殿作为研究对象,对室内混响时间这一重要声学指标进行系统测试,具体比较分析了每个空间不同位置各频段的混响时间T30与T10数值、3个空间的混响时间差异及其与宫殿功能之间的对应关系。测量数据表明这3个大殿的室内声学品质良好,混响时间能够较好的满足各自的使用功能要求。
There is still a lack of research on the sound field in Chinese traditional architecture. The sound field in the three main halls in Shenyang Palace Museum was examined in this study. As an important acoustic index, the reverberation time was systematically measured and analysis was made in terms of the measurement data of T30 and T10 at different locations at various frequencies, and in terms of the relationships between reverberation time and the function of each hall. The results indicated that the three halls all had good acoustic quality, and their reverberation times could well satisfy the needs of respective functions.
