abstract = "An analytical model for broadband sound transmission loss (STL) of a finite single leaf all using a metamaterial was previously developed and validated numerically. It is of interest to validate the analytical model with experimental results. In this paper, the band gap (BG) behavior
of a locally resonant metamaterial is tested and compared to the analytical and numerical results. First, the unit cell resonance is measured and the material properties extracted. Then, vibration analysis of a metamaterial plate of 0.5 x 0.4 x 0.003 m is carried out. The influence of the
variability of the properties of each of the resonators due to the construction method is analysed. Lastly, the result is compared to the analytical model and conclusions drawn.",
