Sound transmission loss enhancement through triple-peak coupled resonances acoustic metamaterials

Coupled resonances mechanisms combined with the notion of acoustic metamaterials offer exceptional sound insulation capabilities, even at the challenging low frequency ranges below 1000 Hz. In this context, the concept of Multiresonant Layered Acoustic Metamaterial (MLAM) emerged as a promising prac...

In this context, the concept of Multiresonant Layered Acoustic Metamaterial (MLAM) emerged as a promising practical realization exploiting this phenomenon to produce a double-peak sound transmission loss (STL) response in a multilayer configuration that allows to overcome the challenge of manufacturing. This study proposes a novel enhanced MLAM-based design (MLAM+) that greatly improves the device’s STL response by allowing the coupling of a third additional peak, when compared to equivalent double-peak configurations. In contrast to existing metamaterial-based solutions, this third peak is not caused by local resonance effects, but through inducing a combined zero-stiffness response on the panel. Through analytical and numerical validation, it is demonstrated that the frequency of this third peak can be controlled through the geometrical features of the layered design, and it can be tuned to broaden the effective attenuation bandwidth and/or to increase the level of attenuation without necessarily increasing the overall mass and maintaining the load-bearing capabilities of the panel. This opens the path towards a metamaterial’s design methodology capable of tackling different functional outcomes depending on the application.The authors acknowledge the Spanish Ministry of Science and Innovation (Spain) (MCIN/AEI/10.13039/501100011033) for supporting G.
