Abstract: Ballistic walls include a plurality of interlocking blocks formed of a bullet-resistant material, a first portion of the periphery of each block having a protruding tongue, a second portion of the periphery of each block defining a groove sized to receive the tongue, and the tongues and grooves of adjacent blocks being mated to each other to form an interlocked structure. Each block may be formed of a stack of panels having a first surface panel, a second surface panel, and an interior panel, wherein the interior panel is offset from the first and second surface panels to form the tongues and to define the grooves. Each block may be formed of a stack of five panels offset from each other. The blocks may be arranged in a running bond, such that the vertical seams of one course are offset from the vertical seams of an adjacent course.

Abstract: Sound absorbing walls include a planar front panel element formed of an acoustically transmissive material and having a peripheral edge, a planar inner panel element formed of an acoustically absorbent material, having a peripheral edge, a front face abutting the front panel, and an opposed rear face, and a rigid frame having a panel portion overlaying the rear face of the inner panel element, and having a peripheral edge, and an edge portion forming a rim depending from the peripheral edge of the frame, and enclosing the peripheral edges of the front panel and inner panel. The frame may encapsulate the front panel and inner panel, except for an exposed front panel front surface. The rim may extend forward of the front panel. A sound wall may be constructed by connecting edge portions of one or more panels to spaced apart first and second ground-mounted vertical support columns.
