Design of a single-seat acoustically insulated box. The walls consist of several layers including 2 layers of MDF (internal and external), a layer of high-density acoustic plasterboard, a layer of anti-vibration rubber and a thick layer of rock wool inside the cavity. The ventilation holes, such as the holes for the passage of cables have not been made, so as to be made to your liking. If you have no experience with this type of construction, we do not recommend the purchase, or at least the supervision of an expert is recommended.
