In a sound-deadened wall comprising wooden studs, each of which has a front edge and a back edge, a front wall panel is fastened to the front edges of the studs and a back wall panel is fastened to the back edges of the studs. Further, front spacers are positioned along the front edge of each stud, between the front edge of said stud and the front wall panel, so as to define air gaps between the front edge of said stud and the front wall panel, and back spacers are positioned along the back edge of each stud, between the back edge of said stud and the back wall panel, so as to define air gaps between the back edge of said stud and the back wall panel. Each wall panel has two expansive surfaces and the associated spacers are defined by elastomeric strips adhering to such wall panel, on the expansive face to face the associated edges of the studs, before such wall panel is fastened to the associated edges of the studs. Screws are driven through the wall panels, through the elastomeric strips, into the studs to fasten the wall panels to the studs.
