Design Strategies for Narrow and Broadband Noise and Vibration Reduction through Distributed Resonators

Environmental as well as ecological requirements combined with the drive for efficiency have given rise to the introduction of lightweight designs. Nonetheless, their resultant increased stiffness-to-mass ratio often leads to a poor noise and vibration insulation performance. Given the well-known shortcomings of classical noise control measures, thus, their mass and/or volume, novel solutions are pursued. In this context, distributed resonator-based approaches come to the fore as potential candidates to combine good noise and vibration behavior and lightweight design. The main goal of this reserach was to enhance the design of distributed identical (resonant metamaterials) and non-identical resonators arrangements to broaden the frequency region of noise and vibration reduction.
