It is very important to have a better indoor acoustic environment while acting in the atriums, and only in this way can we talk with each other clearly and have a good language articulation. Therefore, to find out the relationship between the space forms of atriums and acoustic environment is a meaningful study. In this paper, the kernel is the space forms of atriums. Firstly, the evolution of the Atrium and classification of the forms are summarized at the point of architectural acoustics. Meanwhile, the points of atrium space simulation process are discussed. Secondly, the acoustic software Odeon is applied to carry out analog simulation. Through data comparison and error analysis between the measurement and simulation, Odeon’s precision, reliability and problems required to be noted in sound field simulation of such spaces are verified. Thirdly, through the analysis of the test data of the atrium space in The Architectural design and research Institute of HIT, the basic characteristics of the acoustic environment of the atrium space are summarized. At the same time, through the simulated analysis, we get the relationship between the sound environment （including sound pressure level and reverberation time） of atrium space and the factors which contain flat forms of atrium space, the layer numbers, absorbing materials, details and so on. Finally, based on the test results and simulating results, some optimal strategies for improving the sound environment of the atrium space are proposed. Keywords: Atrium, Space Form, Sound Pressure Level, Reverberation Time 目 录 摘 要 I ABSTRACTII 第 1 章 绪 论 1 1.1 课题背景 1 1.1.1 课题
