本文对建筑物的吸声结构进行了简要的研究与介绍。首先分析了室内噪声的来源,介绍了吸声的简单机理和吸声材料的种类、特点。然后重点介绍了多孔吸声材料,分析了其影响因素。进而提出了一种新型的建筑物吸声方式—吸声结构体。最后总结了吸声结构选择与设计的原则。 This article briefly introduces and introduces the sound absorption structure of a building. Firstly, the source of indoor noise was analyzed, and the simple mechanism of sound absorption and the types and characteristics of sound-absorbing materials were introduced. Then focused on the porous sound-absorbing material, analyzed its influencing factors. In addition, a new type of sound absorption structure for buildings is proposed. Finally, the principles of the selection and design of sound absorption structure are summarized.
