Hao Feng supply the hole round hole soundproof sound barrier wall can be customized

At present, the impact is mainly used for highway sound barrier overhead composite road Bahn subway and other transportation facilities in the municipal acoustic noise control traffic noise on nearby urban areas, it can also be used for acoustic noise reduction plants and other noise sources. In terms of road noise barriers, Hanks has accumulated a wealth of design and construction experience. Hanks sound barrier design into pure sound barrier reflective insulation, sound insulation and sound absorption combined with the compound sound barrier, the latter approach is more efficient insulation. Currently, most of the sound absorption and sound insulation barrier are selected hybrid products, the products are characterized by the generation and transfer characteristics of the targeted road noise control. Such as car and road friction sound or locomotive and rail grinding sound under way, there is the sound through the on-screen body diffraction characteristics, so the use of the upper and lower absorption in the design, intermediate insulation structure, which can effectively attenuate noise around radio; intermediate transparent sound barrier reflective insulation panels, effectively interrupt transmission of sound waves; but also for drivers and residents a broad vision for the environment. Product Category: sizes can be customized according to customer requirements Application: General acoustics noise control in a variety of high-speed railway viaduct highway Rail stations school construction sites and other industrial enterprises noise reduction products. Road sound barrier works: road noise barrier can be noisy equipment enclosures, so that separate quiet downtown, sound effect, appearance, durability, ease of installation, scene effects and environmental coordination, applicable to the traffic noise, construction site noise and noise of large industrial equipment. Special specifications can be designed according to user needs. Road noise barrier main features: 1, insulation large: the average amount of noise 35dB. 2, the absorption coefficient is high: the average absorption coefficient of 0.84. 3, weather durability: the product has water resistance, heat resistance, UV resistance, temperature changes caused by rain will not degrade the performance or quality of the exceptions. Road sound barrier made of aluminum plate, galvanized sheet, aluminum, H steel columns galvanized surface spray anti-corrosion life of more than 15 years. Frequency, distance and height of the sound source and the receiving point barrier metal sound barrier between the amount of noise and noise factors. A large component of the relationship between metal sound barrier noise reduction and noise frequency of greater than 2000Hz frequency acoustic noise reduction ratio of about 800 to 1000Hz intermediate frequency sound better, but around 25Hz low-frequency sound. Due to relatively long wavelength acoustic and easily diffracted from the barrier above the past, so the effect is poor. Generally, a metal sound barrier to reduce high-frequency sound l0-15dB. Sound barrier height of the metal, according to the design height doubling of distance from the sound source and the receiving point, the metal sound barrier, then the noise increase the amount of 6dB, in order to make the noise reduction effect of better metal sound barrier, should Try to make the metal barrier close to the sound source or receiving point. Metal sound barrier material: galvanized steel, aluminum, color steel, iron, and other metal plate thickness: 0.6mm, 0.7mm, 0.8mm, 1.0mm (can be customized according to customer requirements) Molding thickness: 50cm, 60cm, 80cm , 100cm, etc. (color can be customized according to customer requirements, you can insert a metal plate inserted sound barrier according to drawings custom metal plate sound barrier materials are: galvanized steel, aluminum, iron and other raw material thickness of 0.5mm ~ 1.2mm metal plate inserted sound barrier Specifications: Height is generally 500mm, length 2000mm ~ 2500mm, thickness 100mm ~ 80mm metal plate inserted acoustical sound barrier material: glass fiber cotton and sound-absorbing carpet surface shape: flat and uneven surface corrosion treatment: electrostatic spraying suction volume: 14 -20db sound barrier metal plate inserted refers to the way the sound barrier board is connected to plate inserted above and below the picture slots and can make up the gap between the two link plates easy to install, saving time is such a sound barrier plate is a major feature You can choose the color may be: red, gray, white, blue, green and other colors are available GB same network Hebei Anping gold industry professional production of highway sound barrier, sound barrier metal louvers, road noise network, absorbing network. acoustic panels, acoustic panel noise barrier metal sound barrier is to insert a facility between the sound source and the receiver, so that the acoustic wave propagation has a significant additional attenuation, thereby weakening the influence of noise within a certain area where the recipient of such a facility called sound barrier sound barrier applications: acoustic waves in the communication process, encountered the sound barrier, it will happen reflection, transmission and diffraction barrier three phenomena generally we believe can stop the spread of the direct sound, and systems. Sound attenuation shoot enough, and the impact sound transmission is negligible. Therefore, sound effects sound barrier noise amount may generally be said that it reflects the sound barrier through the sound barrier above two skills in the sound source and the insertion point between the reception of a sound barrier, set up a barrier of infinite length, acoustic diffraction past only from the top of the barrier, and the subsequent formation of an acoustic shadow zone, as the light is blocked to form a shadow as the object. In this acoustic shadow zone inside, people can feel the noise significantly weakened, which is noise reduction sound barrier shorten the construction time to reduce the project cost Material: Metal sound barrier material: galvanized steel, aluminum, color steel, iron and other specifications: metal plate thickness: 0.6mm, 0.7mm, 0.8mm, 1.0mm (can be customized according to customer requirements) Molding thickness: 60cm, 80cm, 100cm (can be customized according to customer requirements) Features: 1), acoustic large: the average amount of noise 36dB. 2), high absorption coefficient: 0.85 average absorption coefficient. 3), weather Durability: water resistance, heat resistance, UV, rain temperature changes will not reduce the performance or quality of the exceptions. Products using aluminum coil, galvanized coil, glass wool, H steel column surface galvanized anti-corrosion life of more than 30 years. 4) appearance: choose a variety of colors and shapes are combined with the surrounding environment, the formation tapestry. 5) Economy: prefabricated construction, improve work efficiency, shorten construction time, saving construction costs and labor costs. 6) to facilitate: parallel with other products to install, easy maintenance, upgrades easy. 7) Security: acoustic board φ6.2 wire rope connecting both ends fixed to prevent secondary damage, personnel, property damage. 8) Light: acoustic panels N series of products with light weight characteristics, square mass of less than 25 kg, bearing load reduce elevated light rail, elevated road, can reduce the cost structure. 9), fire: the use of ultra-fine glass wool, because of its high melting point, non-flammable, fully meet the requirements of environmental protection and fire protection, fire rating of A-level. 10), high strength: the combination of different climatic conditions of the region, to take full account in the structural design wind loads. Using 1.2 mm galvanized sheet, through automated production lines, pressing grooves to increase the strength, the product of anti-10-12 typhoons, compression 300 kg / m. 11), waterproof and dust: Venetian design take full account of water, dust and its angle to 45 °, its sound absorption is not affected configuration Dust drainage measures provided in the dust or rain environment, Avoid water inside member. 12), durable: product design has been fully taken into account wind load road transport vehicle crash safety and all-weather outdoor corrosion. Products using aluminum coil, galvanized coil, glass wool, H galvanized steel column surface.
