N2 - Acoustic metamaterials (AMM) having periodic resonators are well known in the field of acoustic absorber. The major issue, however, is that such AMM are able to band acoustic wave in specific frequency band. In this paper, the spectral-based stochastic method is employed to develop random AMM to overcome the above mentioned issue. Here, the stochastic finite element method (FEM) is applied to random distributed AMM to get maximum band gap. To this end, a FEM model with random distributed resonators is considered to investigate the maximum band gap in the frequency range. The spectral-based stochastic simulation is used to minimize the cost in terms of computational time.
