摘 要: 介绍了厅堂响度的评价指标,然后利用强度指数和厅堂乐队齐奏强音标志乐段的平均声压级LpF对现有的厅堂调研结果进行分析。分析结果与厅堂评价等级结果相符合,而且音质评价较好的厅堂的LpF值与其优选范围相一致。 The loudness in the hall is introduced and the investigated results are analyzed by the strength and LpF which is the mean sound pressure level of tutti-sound. The analyzing results are accord with the hall evaluation class. Moreover, the LpF of the hall which has the good sound quality evaluation is consistent with the preferred scope.
