Low frequency acoustic properties of bilayer membrane acoustic metamaterial with magnetic oscillator
A bilayer membrane acoustic metamaterial was proposed to overcome the influence of the mass law on traditional acoustic materials and obtain a lightweight thin-layer structure that can effectively isolate low frequency noise. The finite element analysis (FEA) results agree well with the experimental...
