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.
Elevated 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, glass fibre reinforced plastic sound barrier with its beautiful appearance, good landscape effect, easy to transport and install, low cost, rust and corrosion resistance,
