Vibration excited sound absorber with dynamic tuning |
摘要 |
Sound radiation from a region of a vibrating surface is reduced by coupling a stiff structure to the vibrating surface using a first compliant element, such that the region of the vibrating surface is substantially covered. A dynamic force is applied to the stiff structure. The dynamic force reacts against a mass element and is selected to minimize the radiated sound. The dynamic force may be applied using a passive, semi-active or active coupling between the mass element and the stiff structure.
