provide some ultra photorealistic options for the use of square cardborad boxes to create sound barriers in an open space. The location is the empty floor of a commercial building. There are columns defining spaces - about 4 meters apart from each other. I would love some inspirational images of how cardboard could be used as a low cost immediate option to help reduce echo issues. The ceiling is about 2.2 meetings high. the images should be in full daytime with good lighting.
