WebDec 7, 2014 · Non constrained damping is any layer of goo adhered to a rigid structure. Studies show that the approach damps resonance but that a significant amount will be required for effectiveness. Think in terms of damping mass and structure mass being similar. As the structure gets heavier the damping becomes less effective. 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. WebHigh damping performance. Constrained layer material provides excellent acoustic damping across a range of frequencies, with advantages over traditional materials at temperatures above 40°C. Lighter weight. Engineered web stem construction delivers similar performance in much smaller parts vs. Al butyl or bitumen. format vidéos
