Scherpinski triangular acoustic diffuser and arrangement method
The invention relates to acoustic diffusion, in particular to a Scherpinski triangular acoustic diffuser and an arrangement method. The Scherpinski triangular acoustic diffuser comprises a mounting plate, wherein two groups of centrosymmetric Scherpinski triangle units are arranged on the mounting plate, each group of units comprises three stages of right-angled isosceles triangle modules generated by iteration, the right-angled isosceles triangle modules are respectively an initial module, two stages of modules and three stages of modules, each group of units is composed of one initial module, three second stages of modules and nine stages of modules, and the height of the modules is based on a 2D-QRD diffuser sequence algorithm. According to the Scherpinski triangular acoustic diffuser, a Scherpinski triangle is used as a prototype of diffuser design, and a modularized fractal design method is combined, so that the effective frequency band of sound diffusion, namely 125 Hz-4 kHz, is widened, and the diffusion effect is superior to that of a 2D-QRD diffuser with the same volume, and is particularly remarkable in middle and high frequency bands; and according to the modular expansion method for optimizing diffusion monomers, design parameters are clear, the monomers are simple in structure, and rapid adjustment can be conducted easily according to acoustic attributes and requirements of the space.
本发明涉及声学扩散，更具体的说是一种谢宾斯基三角形声学扩散体及排布方法，包括安装板。所述安装板上设置两组呈中心对称的谢宾斯基三角形单元，每组单元内包括三级迭代生成的直角等腰三角形模块，分别为初始模块、二级模块和三级模块,每组单元由一个初始模块、三个二级模块和九个三级模块构成。模块的高度基于2D‑QRD扩散体的序列算法；本发明将谢宾斯基三角形作为扩散体设计的原型，结合模块化的分形设计方法，拓宽了声扩散的有效频段即125Hz‑4kHz，其扩散效果优于同体积的2D‑QRD扩散体，在中高频段尤为显著；本发明提供优选扩散单体的模块化拓展方法，设计参数明确，单体结构简单，易于根据空间的声学属性和需求进行快速调整。
