Unit plate type sound barrier interference device and sound barrier formed by same
The invention provides a unit plate type sound barrier interference device and a sound barrier composed of the unit plate type sound barrier interference device, and belongs to the technical field of environmental noise and traffic noise governance. The unit plate type sound barrier interference device comprises a back plate and a panel, and a containing cavity for containing the sound wave interference device is formed between the back plate and the panel; the sound wave interference device comprises a bottom plate, a sound wave interference device is arranged on the bottom plate, the sound wave interference device is composed of sound wave diffusion units which are arranged in different periods, and the sound wave diffusion units which are arranged in different periods are composed of a group of acoustic element blocks which are arranged according to a two-dimensional quadratic remainder rule. The acoustic element blocks form two-dimensional #-shaped structures with different depths so as to change the sound absorption frequency of the sound wave diffusion unit; according to the invention, the sound wave interference device is designed and arranged according to a two-dimensional quadratic remainder rule, so that excellent sound absorption and diffusion performance can be achieved for noise with different frequencies.
本发明提供一种单元板式声屏障干涉器及其组成的声屏障，属于环境噪声及交通噪声治理技术领域，包括背板和面板，背板和面板之间形成容纳声波干涉器的容纳腔；声波干涉器包括底板，底板上设置有声波干涉装置，声波干涉装置由不同周期性排列的声波扩散单元组成，不同周期性排列的声波扩散单元由一组根据二维二次余数规律进行排列的声学元素块组成，声学元素块形成深浅不同的二维井字形结构从而改变声波扩散单元的吸声频率；本发明通过设计有声波干涉装置，根据二维二次余数规律进行排列根据可以对不同频率的噪声具有优异的吸声及扩散性能。
