These are the cabins in the automotive sector where the final controls of the vehicles are made. The sound generated by the vehicle operating at high speeds in the cabin absorbed there. Sound leak is prevented by insulated panels. In addition, the gasses coming out of the vehicle exhaust are filtered through air ducts and fans made in the bottom of the cabin and transmitted to the atmosphere as an environmentally friendly state. Clean air as much as exhausted air is pressed into the cabin.
