highway noise barrier,sound barrier

 noise barrier prices

Sound waves in the process of transmission, sound barriers encountered, reflection, transmission and diffraction occurs three phenomenon.Usually we think barrier to prevent the spread of direct sound, and makes the transmission attenuation, sound enough and the influence of sound transmission can be neglected.Therefore, sound insulation effect of the noise barrier generally can use amount of noise reduction, said it reflects both shielding acoustic noise barrier ability.Inserts a noise barrier between the source and receiver, a barrier to infinite, sound waves can only from diffraction above barrier in the past, and form a sound shadow, after that just like the light is blocked by the object and forms a shadow.In the acoustic shadow area, people can feel noise obviously decreases, this is the noise reduction effect of the noise barrier.
classification

sound barrier audio Classification :
According to the application of environmental noise barrier, divided into traffic noise barriers and noise barrier equipment noise attenuation of noise barriers, industrial factory boundary noise barriers.
According to the material classification and noise barrier can be divided into the following categories: metal sound barriers (metal shutter), metal mesh hole, concrete noise barrier (lightweight concrete, high strength concrete), PC sound barriers, FRP acoustic barrier, etc.Organic glass plate has the most wide and 2.7 meters wide PC toughened in wuxi are into the production, sound barriers factory installation is successful, greatly improve the visual and noise reduction effect
According to the different purposes and can be divided into several categories: railway, highway noise barrier, urban noise barrier, residential area landscape sound barrier drop noise barrier, etc.
Sound barriers between 1 m A 5 m height, cover area effective noise reduction for an average of 10 ~ 15 db (A) (125 hz ~ 40000 hz, 1/3 octave), up to 20 db (A).In general, the higher the sound barrier, or the farther away from the noise barrier, the noise reduction result is better.

Noise barrier Detail description:

1)       Thickness: 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm. 

2)       Width: 1, 220mm, 2, 100mm  

3)       Weight (Kg/M2): 0.8, 1.2, 1.4, 1.6, 1.9, 2.2, 2.4, 2.6, 3.0, 3.3. 

4)       Colors: Clear, lake blue, green, blue, opal, brown, silvery gray, red(Other color can be ordered according to you request)

Advantage:
1, low cost, not only the product production cost is low, and the products are light weight can dramatically reduce the elevated light rail, highways with heavy load, reduce the project cost;
2, strong under prescribed by ritual law: high strength, light weight, can satisfy the various areas of different climatic conditions on the wind load requirements;
3, acoustic performance is superior: magnesium the average amount of acoustic noise barrier is greater than 35 db, average sound absorption coefficient is greater than 0.84, and meet the requirements of every field of noise barrier;
4, fire prevention performance is good, magnesite cementing materials belong to inorganic non-combustible material, composite sound-absorbing material such as glass wool, perlite also has A good fireproof performance, makes the product has excellent fireproof performance, national a-class non-combustible material;
5, use good durability: magnesium the sound barrier waterproof, fireproof, corrosion resistance, resistance to ultraviolet ray, is not affected by rain, snow, wind and sand erosion of the bad weather, such as long service life;
6, installation is simple: magnesium light dead weight, noise barrier can be fabricated construction, high efficiency, short time limit, can save a lot of work in charge;
7, beautiful plastic: according to different needs can be used with the structure of metal material and pervious to light material combination, also can spray all sorts of color and design, in order to meet the requirements of landscape decoration.
8, energy conservation and environmental protection: magnesium raw materials used non-toxic harmless, noise barrier and the production process without heating, no poisonous gas release, is the state encourages the development of environmentally friendly products;
9, broad applicable scope: according to different needs for processing production magnesium the sound insulation board and magnesium the sound-absorbing board, suitable for highway, railway, the railway, culverts, tunnels and other transportation and all kinds of industrial workshop, workshop and residential area, etc.

sound barrier audio Application:
Is mainly used in railway and highway noise barrier along the line,
Is mainly used for highway noise barrier composite, elevated roads, urban light rail, subway and other traffic acoustic noise reduction of municipal facilities, control of traffic noise influence on urban areas near, can also be used for factories and other noise acoustic noise reduction.
Divided into pure acoustic noise barrier reflective sound barrier, and the combination of sound absorption and sound insulation composite sound barriers, the latter is more effective sound insulation.Most of the noise barrier is chosen sound absorption and sound insulation of hybrid product, the characteristics of this type of products is the road noise generation and transmission characteristics of targeted control.Such as cars and road friction or locomotives and rail friction at the bottom of the road, voice through the upper screen diffraction characteristics, so in the design USES the sound absorption, the interval acoustic structure, which could effectively abate the noise diffraction;In the middle of the noise barrier use transparent reflective sound insulation board, can effectively interrupt the transmission of sound waves;At the same time also for the drivers and provide a wide field of vision environment for residents.Architectural acoustics field by acoustic treatment, and control the reverberation time and indoor sound environment, satisfies the requirement of professional venues
