ABSTRACT:
The present invention provides a damper comprising a compressible and resilient shaft and at least one constrained layer damping section attached to the exterior of the shaft via an adhesive. The damper can be compressed and inserted into a cavity or hollow in an article to be damped whereupon it can expand and provide vibration damping properties as well as optional acoustic absorbing properties. The present invention also provides the damped article and a method of damping the article.
