Abstract Membrane-type acoustic metamaterials have demonstrated unusual capacity in controlling low-frequency sound transmission/reflection. First, an analytical vibroacoustic membrane model is developed in this work to study the band gap movement behavior of sound insulation of the metamaterial. The membrane-type acoustic metamaterial is composed of a prestretched elastic membrane attached a rigid disc-shaped mass. Especially, in the model effects of in-plane axis rotation and the translation freedom of the disc-shaped mass block were respectively introduced. Secondly, the effects of elastic constant of structural unit, and the influence of both quality value and radius size of the disc-shaped mass in this type of vibration absorbing material on the band-gaps movement behavior of low frequency and/or high frequency region were comprehensively explored. The results indicated that the band-gap and its movement feature are effected by quality and radius size of metal disc-shaped mass and also by the elastic property of rubber film material. The larger the radius of the disc mass, the frequency of the low frequency band of "band gap" will shift to higher range. The "band gap frequency" of the system low frequency and high frequency region also obviously increases with mass quality decrease. Meanwhile, with mass changes, the "band-gap" frequency of the middle band is close to the fixed value near 166 Hz. The increase of rubber film elastic coefficient will lead to an increase in the frequency of the "band-gap" of medium frequency band, but this effect is not significant
