On the modelling of membrane-coupled Helmholtz resonator and its application in acoustic metamaterial system

•Two SDOF (single-degree-of-freedom) models for representing the membrane have been proposed.•The transformation coefficients for describing the acoustic-mechanical coupling have been derived.•A MDOF model for representing the membrane coupled Helmholtz resonator has been developed.•An acoustic meta...
