Abstract
Vibroacoustic metamaterials allow for mechanical impedance enhancement of the base structure to which they are attached. The effective frequency range of the metamaterial is called the "stop band", and it depends on individual element geometries and their arrangement. These parameters impact the vibration and sound transmission loss of the structure. Most of the solutions presented in the literature are developed for specific vibroacoustic problems with a pre-selected base structure and an ideal bonding method assumed. This limits the versatility of the developed solution and narrows the number of applications in which it could be used. It would be beneficial if one solution could be exploited in several different applications and suited for mass production. This work studies the influence of the base structure, its mechanical parameters, and its dimensions on the effectiveness of the selected metamaterial prototype. Plates of various thicknesses combined with 3D-printed metamaterials are tested. Sound and vibration reduction parameters and changes in the solution's effective frequency range were investigated based on simulation and measurement results. The dispersion curves and sound insulation simulations were used to evaluate the potential effectiveness. The simulation results were compared with vibroacoustic measurements for selected metamaterial and base structure configurations.
