计算机模拟在厅堂音质设计中的有效性

当前厅堂音质设计中,已普遍采用室内声学计算机模拟软件程序进行工作。使过去无法用公式估算的、与房间形状密切相关的许多重要音质参量得以获得。但是必须注意到众多商品化模拟软件在工程应用中的有效程度,才能正确对待其计算结果。在模拟过程中,如何确切地输入有关界面以及观众席的声学特性资料乃是影响计算结果的另一重要因素,这里涉及许多室内声学问题。因此即使运用同样软件,其有效性在很大程度上还与使用者的室内声学知识和经验有关,不像计算器那样只是单纯的运算工具。

On the Effectiveness of Room Acoustical Computer Simulation in Auditorium Design

Room acoustical computer simulation has been widely used in auditorium design. Since several commercial programs are available presently, many important acoustical parameters relating to room geometry can thus be predicted. These results could not be obtained by the method of calculation with equations. The designers' following interest is on the matter of its effectiveness. As it is known that the accuracy of simulation results generally depends on numerous factors while not only inherent to the software, such as the accuracy of the acoustical input data of all boundaries and audience area used in the auditorium design is strongly to be concerned. Therefore, the influence of the software user cannot be neglected and a high degree of practical experience in room acoustics is required to produce optimal results.
