A main structure that can be constructed using either solid steel assembly (32) or reinforced concrete assembly (33) acts as the main structural component for new and remodel construction. The main structure whether it uses reinforced concrete assembly (33) or steel assembly is comprised of cells of equilateral size and each cell has a passage between inner and outer wall created using this method of construction. The inner wall uses the passages to secure accompanying structures and systems to a wall that use this structural system. The outer wall uses the passages to secure retaining assembly (34) to the structure. Retaining assembly (34) holds a strata of soil to the wall and creates plateaus along face of outer wall. The plateaus created by securing retaining assembly (34) to main assembly's (32) or (33) give vegetation a place to be planted and secured to a wall that incorporate the construction method of this invention. The passages between the inner and outer walls also nurture the vegetation attached to a structure built using this invention's method of construction by allowing direct access to the roots. By allowing direct access to the roots of the vegetation planted on a structure utilizing the construction method of this invention each plant can receive the optimum amount of irrigation, drainage, and fertilizer.

A crashworthy traffic noise barrier system for use alongside a path of traffic, the crashworthy traffic noise barrier system comprises a crashworthy longitudinal barrier extending substantially parallel to the path of traffic and a crashworthy traffic noise barrier wall supported by the longitudinal barrier. The crashworthy traffic noise barrier wall includes a plurality of upstanding posts attached to the traffic noise barrier wall, at least one panel supported between each adjacent pair of posts in the plurality of upstanding posts, and at least one longitudinal beam spaced above a top surface of the longitudinal barrier and extending across the plurality of upstanding posts for redirecting a portion of an errant vehicle away from the at least one panel. The longitudinal beams redirect energy of the errant vehicle away from the panels such that the panels and any fragments of the panels, remain attached to the traffic noise barrier wall. The panels may be transparent and may be reinforced with plastic bands, plastic threads, or a plastic net.

A sound absorption structure body has a housing has a front side and a side face raised at at least a part of an outer edge section of the front face, a gas adsorption body placed in the internal space, surrounded by the front face and the side face, of the housing and physically adsorbing gas in the internal space, a sealing means for sealing the gas adsorption body from the outside, and an acoustic connection section provided at at least either the front face or the side face and functioning as an acoustic mass for acoustically connecting the internal space of the housing and the space outside the housing. The sound absorption structure body achieves both sound absorption in a low -pitched sound range and downsizing of the sound absorption structure body itself.

A vertical conducting portion extends through the insulating layer and electrically connects the metal foil and upper interconnecting layer.

A fencing system and method of manufacturing and installing a fencing system specifically designed to give the appearance of a traditional shadow box or privacy fence, wherein the system uses preformed non-corrosive, structurally sound corrugated panels, posts, posts mounts, channel mounts, and clips that mate and are securable using conventional fasteners.

A panel assembly for a traffic noise barrier wall of the type including opposing slots formed in pairs of vertically-mounted posts is described. The panel assembly includes a sheet, which may be transparent, and a frame disposed along at least a portion of the perimeter of the sheet. Side portions of the frame capture at least a portion of the side edges of the sheet and are received within the opposing slots in drop-down fashion.

The invention relates to a shield besides road to adsorb noise, which comprises a sound adsorption shield and a support frame, wherein the shield plate and the support frame or / and support frame and the base are connected via flexible element or / and damping element, the flexible element and the damping element can be serially, parallel or integrally connected. The invention can improve sound adsorption ability and protect the base, with long service life, less increase on the load of road, and high safety or the like.

An inflatable, noise attenuating panel or barrier, comprised of an inflatable air chamber coated with (wrapped in or attached thereto) an acoustic barrier material, with which to construct a variety of structures that benefit from a degree of soundproofing.

The invention discloses an external-hanging sound barrier for rail transit. The sound barrier comprises a plurality of vertical steel columns located on one side of a rail. Every two adjacent vertical steel columns are fixedly connected through a support crossbeam. A guardrail board is disposed on one side, away from the rail, of each vertical steel column, and a sound absorbing and shielding body is located above the guardrail board. Each vertical steel column is provided with a through hole allowing a steel wire rope to penetrate. The sound barrier further comprises a noise sensor which is disposed on one side, away from the rail, of each sound absorbing and shielding body, and the noise sensor is connected with a control circuit which is connected with a storage battery. The sound barrier has the advantages that the sound barrier is durable in structure, stable in performance, convenient to mount, and good in appearance streamline, main body construction of the rail transit is unaffected, various cables are prevented from being exposed under sunlight, noise on the outer side of the sound barrier can be monitored in real time, and the noise reduction and sound shielding amount of the sound barrier is 10-15dB(A).
