This room has a cube shape, with dimensions of only 6.36m in length. To block noise from outside, the wall of the room is made up of 6 concrete layers, each of which is 30cm thick. Engineers use a porous material made of fiberglass, arranged in the most effective de-draping pattern to cover the walls, floor and ceiling inside. In addition, the floor surface is also supplemented with a net made of steel cable over the foam surface.

The total cost to build this room is 1.5 million USD.
