A wall panel has a block of base material, e.g., expanded polystyrene. A resonator tube is disposed in the block. A sound dampening material is disposed in the resonator tube. The sound dampening material can be recycled mattress or carpet. An inlet pipe extends into the resonator tube. A vent is disposed over the inlet pipe. A barrier wall can be formed by stacking multiple wall panels. Additional resonator tubes can be disposed between the wall panels.

A sound barrier system for use in mitigating noise having an origami sheet or origami-inspired mechanism that can use folding to change configuration and lattice topology; and a plurality of cylindrical inclusions disposed on top of the origami sheet. The plurality of cylindrical inclusions being periodically arranged such that folding kinematics of the origami sheet induces reconfiguration of the periodicity of the plurality of cylindrical inclusions and associated wave blocking of the noise.

A barrier wall has a first vertical support and a second vertical support. A first wall panel is disposed between the first vertical support and second vertical support. A second wall panel is disposed between the first vertical support and second vertical support over the first wall panel. An I-beam is disposed between the first wall panel and second wall panel. The I-beam includes a first flange and second flange extending into the first wall panel and second wall panel. A cable is disposed between the first wall panel and second wall panel. The I-beam includes a ridge around the cable. A grounding cable is attached to the I-beam. The first wall panel includes a first channel extending for a length of the first wall panel. A first sound absorbing material strip is disposed in the first channel. A traffic barrier is disposed under the first wall panel.

A wall element is provided for a noise protection wall. The wall element has a body and at least one outer face. The body has a support towards the at least one outer face, and at least one solar panel is arranged on the support and is connected to the body. The solar panel is inclined relative to a vertical in the direction of an upper face of the wall element. The body has on the at least one outer face at least one sound absorption surface which can be directly reached by incoming sound. The sound absorption surface is inclined at least in some sections relative to the vertical and/or relative to a longitudinal direction of the wall element, and the area of the sound absorption surface is at least equal to the area of a visible face of the wall element.

A sound wall and a method of constructing the sound wall. The sound wall includes a pair of laterally spaced posts, at least one of the pair of posts including: an elongate central member, a flange extending form the elongate central member in a direction substantially normal to the elongate central member, and a fin extending from the central member. The central member, the flange, and the fin may define a cavity for receiving elongate panels. The sound wall may include a plurality of elongate panels extending between the laterally spaced posts and stacked in an elongate direction of the elongate central member. End regions of the respective elongate panels may be retained between the flange and the fin. The sound wall may include an elongate stiffener member positioned within at least one of the plurality of elongate panels.

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. Sound panels are stacked on top of the traffic barriers. A crash panel is located between the vertical posts, above one or more sound panels. The crash panels have recesses at the intersection of their backs and ends. Additional sound panels are stacked above the crash panels. An angle bracket is located in the recess. U-shaped connectors connect the recesses of adjacent traffic barriers together around a post. U-shaped connectors connect the recesses of adjacent crash panels together around a post, and above the traffic barriers and sound panels to achieve a MASH TL-4 crash test rating.

A wall module for a modular wall structure integrates a wall panel portion with a post portion having bottom extensions and at least one groove for receiving a distal end portion of a wall panel portion of an adjacent module. The bottom post extension may be suspended in a post hole and anchored with a material such as concrete.

A device is provided for vertically attaching to a wall, in particular to a noise barrier, including a frame and at least two fins which have solar panels and are provided on a front face of the frame, wherein at least two supporting projections, each with a bearing for supporting the frame, extend outwards from a rear face of the frame, the fins forming elongate frame struts.

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 sound absorbing panel is provided above an uppermost of soundproof panels arranged in plural stages in a vertical direction and each having a back surface opposite to a sound source side, the back surface being formed to be a sound insulating surface, the sound absorbing panel including: an outer frame body having therein an acoustic space in which a first acoustic material is provided, the outer frame body allowing formation of a partition wall separating a sound source and a surrounding area from each other, the outer frame body having, at a front and back portions thereof, sound transmitting surfaces each having multiple sound through holes allowing transfer of sound between the acoustic space and outside thereof; and a second acoustic material provided above an upper end of the outer frame body such that a peripheral surface of the second acoustic material except for a corner portion is air-permeable.
