中文摘要：

近年来，扩散吸声体（Diffsorber）得到广泛应用和认同。对于如何设计和应用扩散吸声体，理论上的工作以及实验测量技术远远没有跟上实践发展的需要。从其应用背景的研究、设计方法的更新，及实验技术的发展三方面进行阐述，对扩散吸声体的相关研究进行合理总结，并指出目前该声学结构发展需要解决的若干问题。

英文摘要：

Over the past decade, a new acoustical surface called diffsorber has been widely used and recognized. With re- gard to how to design and apply diffsorbers, the theoretical and experimental techniques can＇ t keep pace with practice de- velopment. Its application background, design updates, and the development of experimental techniques are discussed, and reasonably the relevant researches on diffsorber are concluded, indicating that a number of issues need to be addressed and further studied.
