Description Soundac PVP is a sandwich metal sheet, designed to reduce vibrations and noise transmission in metal constructions. Soundac PVP consists of two metal sheets with a thin viscoelastic inner layer. The material operates on the constrained layer damping principle. When a sheet or structure made of Soundac PVP is caused to vibrate the shear forces in the constrained viscoelastic layer cause the vibration energy to be converted into heat. Loss factor Metal constructions normally have a very low loss factor (ability to convert vibration energy into heat) typically in the range of 0.001 – 0.01. The loss factor can be increased to 0.3 – 0.8 when using Soundac PVP. This in turn means that the amplitude of resonant vibrations occurring in the construction when it is subjected to structure born sound, will be much lower than for a standard metal construction. This amplitude reduction normally leads to less radiation of sound and to less risk of fatigue failure. The build-in damping of a Soundac PVP Construction will also reduce the need for extra add-on damping materials.
