Abstract
Amorphous (non-periodic) materials, such as glass, lack long-range order and are macroscopically disordered and isotropic. Consequently, amorphous structures have the potential to scatter the incident waves in various directions, unlike crystal structures that exhibit specific directional reflection. The purpose of this study is to clarify the characteristics of an acoustic diffuser using an amorphous structure. First, some amorphous samples with different fineness and slope angles were prepared using Voronoi tessellation. Then, their scattering properties were numerically calculated by the finite element method. In this paper, we discuss the influence of geometric differences on the scattering coefficient and directivity characteristics of the reflected sound.
