ABSTRACT:
An acoustic barrier comprises a free standing wall structure having an exoskeletal framework of gravity interlocked components (preferably of timber) and a filling of the exoskeletal framework. Ideally the structure is tiered and is of substantially constant cross section in each tier, although provision is made to step it up or down to take account changes in the contour on which it is located.
