Simulation Software Design
for acoustical layout and shape optimization of new materials for diffusers in room acoustics and architecture
The present report describes the research on acoustic metamaterials carried out throughout this project. It is of great interest, especially in the private sector, to offer new and cost-effective solutions to solve difficult problems. This need requires a continuous flow of knowledge and technology, between the academics and the private sectors, in order to develop novel products.
Within this effort to provide the partnering company with new resources, metamaterials offer countless opportunities for this purpose. The novel field of acoustic cloaking is studied in depth, and several designs of cloaking devices are presented together, along with their advantages and disadvantages. Performance among them is assessed through the simulations of sound pressure, field distribution and the total scattering cross-section. Lastly, a beam-bending metamaterial is presented and evaluated.
