Shinning chrome aluminum surface
Product Description:
The upper layer, immediately opposite the noise source, is a layer of semi-open cell dense acoustic foam which provides a low-reflection surface. This upper layer of foam provides some sound attenuation, expecially of higher-frequency sound . The butyl rubber layer at the base of the 3-layer material is directly attached to the substrate. This layer acts as both an acoustic barrier (effectively attenuating the transmission of sound energy through the material) and as a damping layer, reducing vibration in the substrate. The Aluminium layer just hold the construction/
