Some people propose a landscape partition acoustic screen, which is designed as an ecological landscape form of plantable green plants, highlighting the natural appearance of green. It not only can achieve the effect of noise reduction but also can be organically combined with the surrounding environment and beautify the environment.
The price of an acoustic screen can be calculated based on square meters and extended meters, most of them are priced in square meters, the price of a metal screen body revolves around 200-500 yuan, and a transparent screen body revolves around 300-500, all are related to the thickness, quality, and anti-corrosion technology of raw materials. The basic formula is raw material price + labor cost + overhead (various wear and tear charges added together) + freight + taxes.
The acoustic screen is usually combined with the terrain, with green soil embankment, planting walls, and other landscapes as the sound insulation barrier in the residential area. This noise barrier landscape should choose evergreen or short deciduous tree species, and combine high and low planting to form a green landscape system. The speed should not be less than 80 km/h. Noise is easily generated at high speed, and it is difficult to achieve the sound insulation effect by using simple sound insulation materials. Therefore, the installation of noise barriers near high-speed kilometers in residential areas is necessary to achieve the sound insulation and noise reduction effect. Each kind of traffic noise barrier has its scope of application, and like the sound barrier highway, the traffic noise barrier used at present is mostly metal sound barrier, sound insulation structure screen (sound barrier) (sound insulation wall): the two main parts are column and screen.
Color steel composite plate acoustic components have good sound absorption performance in the frequency band of 400~800HZ where highway traffic noise energy is concentrated. When the sound barrier guardrail plate is set on both sides and there are strong reflectors on the opposite side of the sound barrier guardrail plate, the acoustic components can absorb the reverberant sound generated by reflection well, so that the sound environment quality of the lane area where the barrier is located can be improved effectively.
When the continuous length of the acoustic screen in the roadbed section is longer than 1000m, an emergency access door shall be set. The setting of the channel door shall not reduce the noise reduction effect of the highway sound barrier. When the sound barrier setting encounters a level crossing road and needs to be disconnected, a warning sign shall be set at no less than 200m before the direction of traffic from the sound barrier opening. For the sound barrier of the bridge section, the acoustic material shall have an anti-dislodging device. The weighted sound insulation amount of non-transparent acoustic materials shall be not less than 26DB, and the weighted sound insulation amount of transparent acoustic materials shall be not less than 20DB; the noise reduction coefficient of acoustic materials with sound absorption performance shall be not less than 0.60; the acoustic materials of sound barriers shall not produce dysfunction, residual deformation or damage, and their maximum elastic deflection shall not exceed L/300, and the residual deformation shall not exceed L/300, and the residual deformation should not exceed L/600.
Suzhou Yuheng Textile Co., Ltd conducts many tests on acoustic screens for connection before they leave the factory, and the quality qualification rate is guaranteed.
