In summary,the interval uncertainty is introduced to the acoustic metamaterial with Helmholtz resonators.And then,new descriptions(the conservative approximation,the unsafe approximation and the approximation precision)on uncertainties of physical properties of this interval acoustic metamaterial are defined.Lastly,an optimization model for this interval acoustic metamaterial is proposed.The organization of this paper is listed as follows.The acoustic transmission line method(ATLM)for an acoustic metamaterial with Helmholtz resonators is described in Section 2.In Section3,uncertain analysis of the interval acoustic metamaterial is presented.In Section 4,optimization model of the interval acoustic metamaterial is proposed.The discussion on optimization results is shown in Section 5.In section 6,some conclusions are given.

In summary, the interval uncertainty is introduced to the acoustic metamaterial with Helmholtz resonators. And then then, new descriptions (the conservative approximation, the unsafe approximation and the approximation precision) on uncertainties of physical properties of this interval acoustic metamaterial are defined. Lastly, an optimization model for this interval acoustic metamaterial is proposed. The organization of this paper is listed as follows. The acoustic transmission line method (ATLM) for an acoustic metamaterial with Helmholtz resonators is described in Section 2. In Section 3, Uncertain Analysis of the interval acoustic metamaterial is presented in Section 4, optimization model of the interval acoustic metamaterial is proposed. The discussion on optimization results is shown in Section 5. In section 6, some of the conclusions are given.
