A multi component or multi layered wall structure is provided to attenuate noise transmission through the wall 5 structure which is typically used as a dividing wall or party wall between two adjacent rooms. The wall structure has two internal wall components, one of which is typically a steel stud wall and the other a building panel, typically, an autoclaved aerated concrete panel 10 arranged to extend from floor to ceiling in approximate alignment with each other. A first lining in the form of a board, such as one or more sheets of fire rated plasterboard, is attached to the outer surface of the stud wall to form one outer surface covering of the wall is structure facing into one room. The first lining does not extend from floor to ceiling but rather terminates near to the ceiling so that the stud wall has a covered part and an uncovered part. A similar second lining of plasterboard is attached to the outer surface of the 20 building panel to form the other outer surface of the wall structure facing into the other room. Again, the lining terminates short of the ceiling. Even though the two linings on either side of the wall structure do not extend entirely from floor to ceiling, the wall structure is 25 compliant with the relevant building codes with respect ot sound transmission therethrough. The wall structure has optional other components such as one or more gaps or spaces, and additional layers of the same or different materials. The advantage of the wall structure is that it 30 is less costly and time consuming to build. 5037399_1 (GHMsuIers) P92694.AU.1 32- 28 - -- 4 a1 Ix |
