Abstract: A wall system and particularly a load-bearing spine wall defined by rigidly connected spine panels which are usable in conjunction with and connectable to branch panels for defining workstations. These spine panels include an interior frame having plural hollow cross beams rigidly joined between parallel uprights. The cross beams have elongate slots extending lengthwise along the sidewalls thereof. Each side of the frame permits one or more removable covering tiles to be attached thereto for defining the exterior surface of the spine panel. Load-bearing components having cantilevered hangers can be engaged within the elongate slots which extend lengthwise of the cross beams. Vertically adjacent tiles have longitudinal edges spaced to define a narrow elongate passage therebetween which aligns with the mouth of a respectively adjacent hanger-accommodating slot.

Abstract: A sound attenuating relocatable partition wall panel. A substantially rigid first skin is secured, in a spaced apart relationship to a substantially rigid second skin generally opposite thereto. The first and second skins have different respective critical frequencies at which a coincidence dip occurs in their respective sound transmission loss characteristics.
