Soundproof mat and soundproof material "CISILENT"

Easy and flexible noise control measures that can accommodate various conditions (patented).

As environmental awareness increases and it becomes clear that severe noise can harm health, effective measures are being sought. In places where traditional heavy and rigid concrete systems cannot be used, the lightweight and flexible CISILENT sound barrier demonstrates excellent effectiveness. Even in cases with spatial and technical issues, weight restrictions, and other constraints, new possibilities open up both indoors and outdoors. CISILENT efficiently solves noise problems. It has a lightweight structure that allows for installation in narrow spaces and easy transportation. It can be easily assembled, making it suitable for use as a temporary system. The transmission loss of the flexible sound barrier CISILENT is Rw=25dB, meeting the requirements of the German guidelines for road noise barriers (ZTW-Lsw 88). Moreover, when comparing the weight per unit area, it is significantly lighter than conventional sound barriers. Solid components, even if they have the same mass per unit area as CISILENT, have inferior sound insulation effects because their high rigidity causes sound to hit the surface and disperse again. In contrast, the flexible CISILENT exhibits sound insulation effects commensurate with its mass.
