The Bean Bag Damping Technique and its Application |
| |
| Abstract: | The Bean Bag Damping (BBD) technique and its mechanism of impact damping are presented in this paper, and this technique is applied to the control of wall vibration and interior noise in a thin-walled enclosed cavity. The results of the experiment show that the BBD technique is simple and convenient, its controlling frequence band is wide, and the effect of damping and noise reduction is notable. |
