A knock-down sound attenuating system (10) is provided as a portable enclosure having significant sound attenuating properties, while still being easily assembled and disassembled. The knock-down sound attenuating system (10) includes a plurality of sound attenuating wall partitions (14,16) whose longitudinally extended end portions have at least one longitudinally extended recess (78) formed therein. System (10) further includes a coupling gasket (50,70) having at least a pair of opposing projecting members (52 and 54), (74 and 76) for receipt within a recess (78) formed in a respective one of the wall partition end portions. Coupling gaskets (50,70) simultaneously provides both an interlocking between adjacent wall partitions (14,16) and an acoustic seal for the interface therebetween. To secure one wall partition (14,16) to another, system (10) further includes a flexible coupling system (18) comprising a strap-like member (28) coupled adjacent a longitudinal side of a partition (14). Strap-like member (28) extends across the joint formed between two adjacent wall partitions (14,16) for releasable engagement with a coupling (38) disposed adjacent the longitudinal edge of the adjacent wall partition (14,16).
