利用声散射理论与随机信号处理理论的相似性，通过对随机过程的理论分析，阐明了声扩散体设计的本质在于其表面阻抗变化的随机性，在更一般的层面上解析了目前各种各样的设计方法。数值分析表明，即使运用古代易经理论产生一个随机序列，亦可制作成散射性能良好的扩散体。因为通讯技术的迅猛发展，随机序列的研究获得长足进步，借鉴这些领域的成熟研究成果，可为声学扩散体进一步的优化设计提供广阔的设计思路和必要的理论支持。

Making use of the similarity between the theory of sound diffusion and random signal processing, a theoretical analysis of random process is conducted to strictly prove that the essence of designing sound diffuser is the randomicity of impedance along its surface. A more general and clearer explanation to design technique of sound diffuser is achieved. Nu-merical analysis shows that even using the ancient I-Ching theory can generate a random sequence, which can be applied to diffuser design. Because of the rapid development of communication technology, the studies of random sequence have made considerable progress. Learning from these mature achievements, a wide range of design ideas and the necessary theoretical support for further optimization of the acoustic diffuser design can be obtained.
