Acoustic material

Soundamp(R)is a family of noise attenuating metal laminate products based on the "constrained layered" vibration damping principal. The acoustic material can be used to replace standard homogenous metal panels or formed parts, which traditionally require additional sound insulation treatments. It consists of two outer sheet metal skins with a thin viscoelastic polymer inner layer.
