中文摘要:
      本文回顾、综述了对音乐厅(包括西洋交响乐厅及中国民族音乐厅)响度评价的研究历程,指出采用乐队齐奏强音标志乐段的平均声压级LpF作为评价音乐厅响度客观指标的合理性与可行性。文中给出LpF的计算方法以及对若干厅堂计算值与实测值的比较,并通过主观评价,给出LpF的初步优选值域。采用LpF作为响度评价指标的好处不仅在于它能表征听众听到的绝对响度的感受,还在于能预判何种规模的乐队适于在多大规模的音乐厅中演出,以便达到较佳响度效果的问题。
英文摘要:
      This paper looks back and summarizes the investigation into concert hall (including both of western orchestra hall and Chinese national music hall) loudness evaluation and demonstrates that the suggestion of LpF, the mean forte sound pressure level of tutti-sound as a criterion to describe the loudness in a hall is suitable and reasonable. The prediction procedure of the LpF value distribution in a hall is also demonstrated. Comparison results between predicted and measured LpF data in some halls are shown. Some tentative optimum or allowable LpF values for concert halls are given. The merits of using LpF as a loudness criterion are that it can describe the real loudness impression of audience and it can also predict what kind of orchestra with suitable number of musicians can suit to a large or small hall to produce a perfect loudness impression.
