在对Leo Beranek著《音乐厅和歌剧院》一书中所提供的80余所音乐厅和歌剧院声学参数的测定结果数据分析的基础上,经过简单的数学处理和简化,提出一些个人见解:强度因子G和座位数N的关系;对于N小于和等于2000的音乐厅,空场早期衰变时间EDT等于空场混响时间。文中给出在N>2000的情形下空场EDT的计算。座椅数是决定厅堂容积的出发点,由此做出两个厅堂的初步设计实例。 Based on the data analysis of the measurement results of acoustic parameters of more than 80 concert halls and opera houses provided by Leo Beranek in the “Concert Halls and Opera Houses”, some simple ideas on math processing and simplification are put forward: Strength Factor G and the number of seats N; for N less than or equal to 2000 concert hall, the empty decay time EDT is equal to the empty field reverberation time. The calculation of the open-field EDT is given in the case of N> 2000. The number of seats is the starting point for determining the volume of the hall, thus making the initial design example of two halls.
