In this paper, vibration damping properties of constrained type which has three layered plate from steel sheet/visco -elastic material/steel sheet were studied on fixed and free conditions around the plate of test sample. The loss factor of constrained type generally has been considered to be affected theoretically and experimentally by visco -elastic properties of midlayer and configuration of each layer. Furthermore vibration damping properties are con sidered to be affected also vibration mode and shape of test sample. It could obtain higher loss factor and lower compliance in comparison to fixed condition than free condition. Therefore, it was clarified to controll by around the plate that vibrating damping effect is exserent large effect.
