Large spaces, circular in plan, can be preferred by architects to design large auditoria, even though they can cause acoustical singularities such as focusing and whispering gallery. In large auditoria for multipurpose functions are becoming a common request to use the space for different activities such as conferences, concerts of classical and amplified music, shows, etc. and the necessity to find architectural solutions in order to consider the variable acoustic demands according to different possible layouts, are growing. In this paper, as a case study, architectural acoustic design approaches and solutions for a circular auditorium are presented. The case study was made in "Le Serre" hall for 1000 people, in the Villa Erba Convention Center, located in Cernobbio (Italy), in which different combinations of movable architectural elements are developed to create a multipurpose space. A geometrical acoustic analyses are included, followed by the description of different methods to avoid focusing and whispering. Room acoustics procedures and implementations of computer simulation techniques are developed.
尽管大空间可能会导致诸如聚焦和声廊等声学奇异点，但建筑师在设计大型礼堂时可能更倾向于采用平面为圆形的大空间。在大型多功能礼堂中，将空间用于不同活动（如会议、古典音乐和扩声音乐音乐会、演出等）的需求日益普遍，并且根据不同可能布局考虑可变声学需求的建筑解决方案的必要性也在增加。本文以一个圆形礼堂为例，介绍了其建筑声学设计方法和解决方案。该案例研究是在位于意大利塞尔诺比奥的埃尔巴别墅会议中心的“勒塞尔”千人礼堂进行的，在该礼堂中开发了不同可移动建筑元素的组合，以创造一个多功能空间。文中包含了几何声学分析，随后描述了避免聚焦和声廊的不同方法。还开发了室内声学程序和计算机模拟技术的实现方法。
