The dB15 Soundboard is a combination of ply cardboard and silica sand. Sand is added to the cardboard and serves as a dense mass material to be used in conjunction with other soundproofing materials on walls, floors and ceilings.

The dB15 Soundboard is specifically designed to insulate sound travel. The sound pressure wave will interact with the mass and density of the sand. This will reduce the energy of the wave and so reducing the intensity. And has been independently tested to * 39 dB noise reduction

The dB15 tape is a sticky and flexible self-adhesive tape, which will keep the sand in the flu. dB15 Soundboard has a one directional flu, when installed horizontally the flu line will minimise sand loss. Therefore, it is quite easy to install pockets in the dB15 Soundboard for example dB15 Backboxes or electric sockets.
