A traffic barrier and soundwall system is disclosed having wide-flanged [or H-posts] vertical posts oriented with a flange facing a roadway. Traffic barriers are located between them. The barriers have recesses at the intersection of their backs and ends. An angle bracket is positioned in the recess to separate the post from the barrier. A U-shaped strap has a base and a pair of arms extending from the base. Traffic barriers are positioned against the posts so that the angle brackets in the recesses are adjacent to the road-facing flange of the post. A strap fastener connects an arm of the strap to the recess of each of the adjacent traffic barriers. In this way, the base of the strap surrounds the rearward-facing flange of the post to secure the traffic barriers to the post. Sound barrier panels are located on the top of the traffic barriers, secured between the webs of the neighboring posts.

A sound absorbing structure includes a wall having a first side and a second side and at least one acoustic scatterer coupled to a first side of the wall. The first side of the wall may be positioned to face a source of noise, such as moving motor vehicles, airplanes, and the like. The at least one acoustic scatterer has an opening and at least one channel. The at least one channel has a channel open end and a channel terminal end with the channel open end being in fluid communication with the opening.

Airborne acoustic absorbers include periodic arrays of Helmholtz resonators that are covered and/or partially filled with an acoustically absorptive material, such as a thermoplastic foam. The combined structures have much broader frequency ranges of high acoustic absorption than do structures having only Helmholtz resonators or acoustically absorbing foam.

A barrier-wall structure having a retaining wall with a back support surface supported by backfill adjacent thereto, wherein the backfill is municipal solid waste processed into fill-material in the form of a multiplicity of biologically-inert compacted pieces.

A noise abating wall including piers with integral column members, columns each including two laterally extending wing walls, and a spandrel panel. The piers are secured in spaced ground holes with column members extending vertically from the pier securing the columns in a vertical orientation with the wing wall outer sides having a selected spacing from one wing wall of an adjacent column. The spandrel panels are wider than the selected spacing of wing walls of adjacent columns whereby the spandrel panel sides overlap the sides of adjacent wing walls. First connectors on the spandrel panel front face adjacent both of the panel opposite sides and second connectors on the wing wall rear faces adjacent the wing wall outer sides connect together to secure the overlapping walls and spandrel panels in substantially face to face contact.

The application relates to a noise control device including a substantially vertical wall element, at least one side arm projecting from the wall element, and at least one solar module supported by the side arm, wherein the side arm laterally supports the wall element, wherein the wall element forms a noise control surface above an upper edge of the solar module; as well as a noise control system including a noise control device of this type and an additional wall element spaced apart from same, which has an additional noise control surface and an additional solar module, wherein a height difference between the lower edge of the solar module of the noise control device and an upper edge of the additional wall element is less than or equal to 0.6 times the horizontal distance between the edges, and/or a height difference between a lower edge of the additional solar module and an upper edge of the noise control device is less than or equal to 0.6 times the horizontal distance between the edges.

A noise barrier system and method for quickly and modularly installing or erecting a temporary sound interruption wall. The system can include one or more panels each, a leveling bracket adjustably mountable to a support member, a clamping bracket for mounting a panel to a support member, a double clamping bracket for clamping a pair of panels together and mounting them to a support member, and a panel clamp for clamping a pair of panels together. The leveling bracket can include a support wall to support portions of adjacent panels, and an arm for removably securing to a flange of the support member. The panel clamp, the clamping bracket and the double clamping bracket can each include open channel configuration configured to receive a single portion of a panel or portions of pair panels, and a slidably adjustable clip for securing the portion of the panels therein.

A sound barrier fence is adapted to reduce the noise level between industrial or business properties and dwellings that use a sound deadening core of fence panels and placement of the panels in a fence to reduce sound transmission.

The invention relates to a sound absorber (1) for a traffic route noise protection wall, wherein the sound absorber (1) comprises at least one plastic foam board (2). According to the invention, a first surface (3) of the plastic foam board (2) has a predeterminable number of sound absorber recesses (4) for predetermination of the absorption behavior with a predeterminable frequency response, wherein each of the sound absorber recesses (4) extends only through part of the thickness (5) of the plastic foam board (2).

Embodiments relate to a plastic wall panel, comprising a hollow body having external walls and defining an internal cavity. The external walls include: a first major side wall, a second major side wall opposite the first major side wall, a minor top wall, a minor bottom wall, a first minor end wall and a second minor end wall opposite the first minor end wall. The minor top wall and the minor bottom wall each define mating structure to mate and align with another adjacent panel so that multiple panels can be tiled together to form at least part of a sound attenuation barrier. The hollow body defines a passage extending between the first and second major side walls and through the first and second minor end walls to receive a reinforcing beam.
