The main objective is to create a comfortable space where the school's noise do not interfere with the silence needed to record and edit sound.
The room has twenty seven square meters of free space. The inner wall is made with split brick filed with sand and it is floated. The floor is a structure made with wood and sand, with carpet on top, and floating foam at the bottom. The ceiling is completely supported by the sand wall, and do not touch the building. It is made of wood, plasterboard, M.A.D4, PKB2, and mineral wool. The door is made of solid wood and mineral wool, with eight centimeter of thickness.
The room also has an ventilation system made with silent motors and conducts, mounted two floors above, as far as possible.
One important aspect of this project is the weight of the structure. The sand wall and the sand floor are too heavy, and it is only possible to build this because it is located on the ground floor. There are others methods to insulate a room, with less mass, and more suitable to build on higher floors, so beware! If you intend to use this technic, always do all the math and ask an engineer for a professional opinion, or you can damage the building in an tragic way!
