Acoustic metamaterialnegative dynamic massmuffler漏2016 World Scientific Publishing CompanyMembrane-type acoustic metamaterials (MAMs) with negative dynamic mass have demonstrated the effects in the sound transmission loss (STL) at low-frequency range. This research aims to design a membrane-type acoustic ...
Among the various types of acoustic metamaterials, membrane-type acoustic metamaterials (MAM) possess excellent abilities in controlling sound waves, particularly in the field of sound insulation [52–65], despite their extremely thin, lightweight, and structurally simple design. The soundproofing ...
It is well known that membrane-type acoustic metamaterials consist of a membrane, an additional block and a frame structure. When subjected to the action of incident sound waves, the membrane and block produce resonance and anti-resonance phenomena, resulting in a good sound insulation effect in ...
Finite element method simulations were used to study the acoustic properties of the fabricated metamaterials. An equivalent electrical circuit was built using an electro-acoustic analogy to evaluate the sound absorption coefficient. The unique design of this meta-structure possesses two resonant frequencies...
