A sound reducing panel is provided for use in construction of barriers of varying height between sources of objectionable noise and any sensitive area adjacent thereto, such as a freeway, a highway, construction or industrial operations, motors, generators, or other noise generating activity. Each panel consists of a designated number of parallel, hollow, triangular-shaped chambers, equally spaced apart and mounted on the panels in equal spaced relation relative thereto with the triangular-shaped panels opening toward the side of the panel opposing the source of objectionable noise. The mounting of the triangular-shaped chambers in spaced relation relative to the panel provides a specifically dimensioned slot along each longitudinal side of the triangular-shaped chambers opening thereinto and the slots act as side branch filters while the convergent opposite sides of the triangular-shaped chambers extending toward the noise source perform as a series of inverted accoustical horns to channel sound into the chambers through the branch filter defining slots.
A sound barrier including an imperforate backing panel, substantially free of openings therethrough, a plurality of elongated, generally parallel imperforate angle members of substantially V-shaped cross section supported from said backing panel in position spaced slightly outwardly of one side thereof and with the apex portions of said V-shaped angle members facing outwardly of said one side, said angle members being oriented in substantially parallel equally closely spaced apart relation.
A sound barrier including a backing panel, a plurality of elongated generally parallel and closely spaced apart sound energy dissipating imperforate cell bodies supported from said backing panel in position spaced slightly outwardly of one side of said panel, said cell bodies being hollow and including open longitudinal sides opening toward said panel, the longitudinal edges of said cell bodies defining said open sides thereof being substantially coplanar and spaced equally from and generally paralleling said one side of said panel, said panel being at least substantially free of openings therethrough in the areas thereof registered with the spacing between adjacent cell bodies and the areas thereof toward which said cells open.
