WebConstrained-layer damping (CLD) is a method of reducing vibration of structures, usually thin and somewhat flexible objects. Less vibration translates into less sound. To achieve CLD, a rigid layer, called the constraining layer, and a viscoelastic layer are attached to the object whose sound needs to be dampened (muffled). WebAn extensional damping system is when the damping product applies to the top of the surface. An example of this would be our Pipe and Duct Wrap. When bent (impact of sound against vibration damping material), the constrained layer damping material will stretch (extension) and compress, allowing some of the sound energy to be converted into heat.

WebConstrained layer damping. Active damping . Elastomeric Damping - Elastomeric damping is perhaps most common. However, damping treatments using damped elastomer often fail, or are only partially effective. The reason for this is, in part, because the deformed shape and structural dynamics are not well understood, but also because of … WebMay 9, 2014 · It's a very strong adhesive yet it maintains a slightly flexible property indefinitely.
