Abstract
Local resonance effects arising in the so-called locally resonant acoustic metamaterials (LRAM) have the ability of effectively stopping waves from propagating in certain frequency ranges, typically known as bandgaps. This can be used, for instance, in the design of insulation panels capable of attenuating acoustic waves in the low-frequency region, i.e. around 1kHz, where more conventional solutions consist of using thick designs with very dense materials. In this context, a computational proce...
