This paper presents a new approach of active control of a window pane. This study can be applied to a window of a house or an office, producing a quite space in the adjacent room. To obtain a high performance of interruptive sound using a light weight material, the active vibration control of the material can be used to improve the transmission loss. The acoustic mode of the cavity greatly influences the window pane in the enclosure. Therefore, when applying vibration control of the structure, set up in the closed space, it is necessary to note the influence of the acoustic mode.
