怎样设计防声墙 在声波的传播途径上,若有墙或建筑物之类的障碍物时,声波具有跨越障碍物或绕过障碍物横端(类似光向它的阴影部分传播)的性质。我们把跨越障碍物,绕过横端的现象,叫做声波的绕射。 这种绕射现象,波长较长的低频声比波长较短的高频声更显著。也就是说,波长越长,绕 How to Design Soundproofing Walls In the path of sound waves, when there are obstacles such as walls or buildings, sound waves have the property of crossing an obstacle or bypassing the cross-piece of an obstacle (similar light is transmitted to its shadowed part). We cross the obstacles, bypassing the phenomenon of cross-side, called sound diffraction. This diffraction phenomenon, the longer the wavelength of low-frequency sound than the shorter high-frequency sound more pronounced. In other words, the longer the wavelength, around
