Abstract

Early reflections are an important factor for the acoustic conditions on stage. To better understand their effect on the perception of musical performers, an experimental study was conducted to investigate how the time and direction of arrival, the diffusivity and the strength of early reflections affect the perceived acoustic quality on stage. Architectural variations of a typical stage structure were created in computer models. Combinations of different stage widths, canopy heights, and surface scattering were modelled using geometric acoustics and Boundary Element Method (BEM) simulations. Listening experiments carried out with musicians of different instrumental groups playing with real-time auralisations of these virtual concert hall stages revealed that both the time and direction of arrival of early reflections have a significant effect on the stage acoustic conditions perceived by solo musicians. In a larger battery of stage acoustic parameters determined for each architectural variation, the ‘Top to Sides’ and ‘Top to Horizontal’ ratios (TS, TH) proved to be the best predictors of the acoustic quality of the stage configurations presented, although the interrelation within the musicians seems to be less uniform than for room acoustic parameters from the audience perspective.

早期反射如何影响独奏音乐家的舞台声学条件

早期反射是影响舞台声学条件的一个重要因素。为了更好地理解它们对音乐表演者感知的影响，我们进行了一项实验研究，探讨了到达的时间和方向、扩散率和早期反射的强度如何影响舞台上感知的声学质量。一个典型舞台结构的建筑变化是在计算机模型中创建的。利用几何声学和边界元法（BEM）模拟了不同舞台宽度、冠层高度和表面散射的组合。不同乐器组的音乐家在虚拟音乐厅舞台上进行的实时听觉实验表明，早期反射到达的时间和方向对独奏音乐家感知的舞台声学条件有显著影响。在为每个建筑变化确定的更大的舞台声学参数中，“顶部到侧面”和“顶部到水平”比率（TS， TH）被证明是舞台配置声学质量的最佳预测指标，尽管从观众的角度来看，音乐家之间的相互关系似乎不如房间声学参数那么均匀。

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
