Overview
Good noise absorption performance is an important factor for modern
architecture , it can reduce the noise of the inside and outside of
the buildings through the punching process on the surface of steel
plate or changing the insulating core material. The optional
sound-absorbing material, such as rockwool, glass wool.Change the
core material type and density to reduce noise caused by the
collision of metal surface. Through the experiment, the effect of
noise reduction depends on the noise frequency and the core
material thickness. By both changing the sound-absorption material
and punching on the plate can reduce more than 29 DB .
