Sound Barrier Products

Sound barrier perforation

Perforated sound barrier hole type is mainly divided into louvered hole sound barrier, round hole sound barrier two types of holes. The perforation type we often see in high speeds, neighbourhoods and factories is dominated by louvered holes.  The noise reduction effect is better for the high frequency sound greater than 2000Hz than the medium frequency sound around 800-1000Hz, but for the low frequency sound around 25Hz. However, for low frequency sound around 25Hz, the effect is poor because the wavelength of sound is long and it is easy to bypass from the top of the barrier. Usually, the sound barrier can reduce the high frequency sound by l0-15dB. The height of the sound barrier can be designed according to the distance between the sound source and the reception point, and the height of the sound barrier can be doubled, so the noise reduction can be reduced by l0-15dB.

Underground Sound Barrier Products

A facility is inserted between the sound source and the receiver so that there is a significant additional attenuation of the sound wave propagation, thus attenuating the noise impact in a certain area where the receiver is located, and such a facility is called a sound barrier.  With the rapid development of highways, railways, urban light rail, underground, etc., although people's travel brings great convenience, but at the same time it produces noise pollution has also become a prominent social problem, and sound barriers have become the most effective and feasible way to solve the problem.  With the continuous development of high technology, in recent years, the glass fibre reinforced plastic sound barrier has become the most effective and feasible solution to the problem with its beautiful appearance, good landscape effect, convenient transport and installation, low cost, rust and corrosion resistance.

Highway sound barriers

Highway sound barrier, also known as noise wall, sound-absorbing barrier, anechoic shutters, is a sound-absorbing material for the core material, the use of colour steel sandwich panel acoustic components assembled into the absorption, acoustic isolation barrier. Colour steel sound barrier sound-absorbing acoustic components can be processed into several kinds of sound-absorbing and sound-insulating acoustic units such as louvered, perforated, micro-perforated and slotted holes. Shutters and perforated sound-absorbing colour steel composite panels have better sound insulation performance in medium and high frequencies, and colour steel composite panel acoustic components without slotted holes have better sound insulation performance in medium and low frequencies. Therefore, different structural forms of sound barrier can be selected according to the noise characteristics.

sound barrier

Highway sound barrier, contact person: Mr Ma contact phone: 13679083499 sound barrier is mainly used for highways, elevated composite roads, urban light rail underground and other transport and municipal facilities in the sound insulation and noise reduction, control of traffic noise on the nearby urban areas, but also can be used for factories and other noise sources of sound insulation and noise reduction.

High-speed rail sound barrier products

High-speed railway sound barrier is a kind of sound barrier designed according to the needs of current high-speed railway.  Features of high speed rail sound barrier: large sound insulation capacity, high sound absorption coefficient, high strength, strong weather resistance, beautiful, easy to install and maintain, and can be sprayed with various colours according to the user's needs Usage of high speed rail sound barrier: high speed rail sound barrier is widely used in high-speed railways, inter-city railways, urban light railways and other sound barrier projects.  Technical parameters of high-speed railway sound barrier: 1, sound insulation: 46.3dB (A); 2, sound absorption coefficient: 0.87; 3, wind pressure resistance: 3 seconds gust wind pressure (P = ± 3.00KPa) test

Sound barrier bending

Bending type sound barrier used for highway and community more, mainly play a role is to make the top of the sound can be refracted back to achieve further sound insulation and noise reduction effect. Bending sound barrier specifications: 1960 * 500 * 80 (length * height * thickness) bending sound barrier internal structure: sound-absorbing materials as the core material, the use of colour steel sandwich panel acoustic components assembled into.

Sound Barrier Pillar

Sound barriers are mainly used for sound insulation and noise reduction in transport and municipal facilities such as highways, elevated composite roads, urban light rail subways and other transport facilities, controlling the impact of traffic noise on the nearby urban areas, and can also be used for sound insulation and noise reduction in factories and other noise sources.

Highway sound barrier construction

Sound barriers are mainly used for sound insulation and noise reduction in transport and municipal facilities such as highways, elevated composite roads, urban light rail subways and other transport facilities, controlling the impact of traffic noise on the nearby urban areas, and can also be used for sound insulation and noise reduction in factories and other noise sources.
