音乐厅的灯光与舞台设备不如歌剧院复杂,但其音质是各种厅堂中最关键的,不能只用单一声学参数评价.声学设计通常只给出总体效果.预测声学设计结果的困难在于对多个声场参数的综合.本文建议采用多维玫瑰图计算面积系数的方法作为对声场进行综合评价的技术规则,图中的每一个维度分别代表一声场参数.因此,需增大厅堂中具有较佳音质的玫瑰图的面积.根据国际标准(ISO3382),对音乐厅进行的测试通常仅对少数经过选择的位置进行.而今通过数字仿真可预测每个座位处的音质参数,并且可以得出音质参数的优选位置的比率.从这些统计数据中,不仅可以比较不同声学设计方案,还可知道如何改进声学设计.本方法被应用于某一中等尺度厅堂的五种不同顶棚设计形状的比较,并得出优化方案.
Concert Hall lighting and stage equipment is not as complex as the opera house, but its sound quality is the most critical of all kinds of halls, not only using a single acoustic parameter evaluation. Acoustical design usually only gives the overall effect. A synthesis of sound field parameters.This paper proposes to use the method of multi-dimensional rose diagram to calculate the area coefficient as a comprehensive evaluation of the sound field technical rules, each dimension represents a sound field parameters.Therefore, to increase the hall has better sound quality Of the rose map area.According to the international standard (ISO3382), the test of the concert hall is usually only a small number of selected locations.Now through the digital simulation can predict the sound quality parameters at each seat, and can be derived from the sound quality parameters Preferred location ratios from which to compare not only different acoustical design schemes but also how to improve the acoustical design.The method was applied to the comparison of five different ceiling design shapes for a medium-sized auditorium and resulted in Optimization.
