音乐厅音质设计

本文简要介绍音乐厅建筑实践的发展史和四个最近设计成功的大厅。简要叙述现在于大厅内能测量且与主观响应有关的客观参数，即混响时间、初始时间延迟间隙、响度、扩散、侧向反射和早期对后期能量比。最后，简短地报道近来声场模拟方法的发展，用这些方法可以预测某些声学特性。

The acoustical design of concert halls

This paper presents a short introduction into the developed history of the design of concerthalls and the success of four recently designed halls. A brief account is given of the objective parametersthat can now be measured in halls and ralate to subjective response. These parameters are reverberationtime, initial time delay gap, loudness, diffusion, lateral reflection and early to late energy ratio. Finally,recently developed methods of sound field simulation are briefly introduced by which some acoustical properties can be predicted.
