Abstract: Acoustic metamaterials (AMM) increase in importance with their ability of reducing determined frequency stop bands within a noisy environment. For instance, electric drive components show emissions of noise in the mid and high frequency range from 1 to 10 kHz. By using AMM with a lattice structure design, the requirements of lightweight, stable and tunable acoustic reduction are satisfied. The lattice structure design is characterized by a layer of periodic unit cells including cavities. Developing an array of unit cells, those cavities are interconnected by pores. The design process of the Face Centered Cubic (FCC) lattice structure is presented. Simulation results of the sound transmission loss within the mid and high frequency range are carried out.
