An acoustic screen is inserted between the sound source and the receiving point, and the barrier is set to be infinitely long so that the sound waves can only be bypassed from above the barrier, and a sound shadow zone is formed afterward, just as light is blocked by an object to form a shadow. In this shadow zone, people can feel the noise is significantly reduced, which is the noise reduction effect of the sound barrier.
When sound waves encounter a sound barrier during propagation, three phenomena, reflection, transmission, and bypassing, occur. Usually, the barrier can stop the propagation of direct sound and make the transmitted sound have enough attenuation, while the effect of transmitted sound is negligible. Therefore, the sound insulation effect of an acoustic screen can generally be expressed by the amount of noise reduction, which reflects the above-mentioned two kinds of shielding sound transmission capabilities of the barrier.
High-intensity cement-based lightweight composite sound-absorbing and sound-insulating barrier
Lightweight and high-intensity cement sound-absorbing and sound-insulating panels are efficient sound-absorbing and noise-reducing products produced by advanced technology and raw materials, with a technical performance at the domestic advanced level. Various types of structures and beautiful appearances. It can meet different design requirements and is widely used in noise control projects for highways, railroads, viaducts, and industrial plant boundaries.
Rock Panel Sound Absorption
Perlite is a kind of fine porous, inorganic cement combination, it does not contain pollutants, and basically is made of cement, natural minerals, and other chemical materials through special treatment, mixing, and molding, so durable, and has very high plasticity, can be deployed into different weight, shape, color, appearance to adapt to different installation and design conditions, can meet the different needs of practical applications.
Compared with other existing acoustic and sound insulation materials, perlite materials have the following characteristics.
Perlite acoustic screen has stable sound absorption performance, a noise reduction coefficient of NRC0.85 or so, and good sound absorption performance in the high-frequency region of noise, which meets the acoustic requirements of road sound barrier.
Simple application and installation can be prefabricated or formed on-site.
No organic ingredients, no polluting ingredients: for example, asbestos, mineral fiber, polystyrene, and cellulose does not absorb water, are resistant to weather erosion, are easy to clean, and can be used bare in the open air environment, strong durability, resistant to natural aging.
Low weight capacity, high temperature, low temperature, acid, alkali erosion resistance, fire prevention.
The acoustic absorption band is wide, the noise reduction coefficient is NRC0.85 or so, sound insulation amount of 46dB.
Soft color, multi-color selection, beautiful and generous, continental style.
Perforated plate sound absorption
The principle of a micro-perforated plate is to drill a certain number of holes in the plate and leave a certain air layer behind the plate to make the incident sound waves resonate and absorb, to achieve the effect of sound absorption. Micro-perforated panels sound barriers have been widely used on highways, urban elevated places, etc. The material of micro-perforated panels has developed from the earliest PC board and acrylic board to many kinds of metal materials such as color steel plate and aluminum plate.
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. The above is about the information about the acoustic screen and the material of the acoustic screen. If you are interested in acoustic screens, you can consider our cost-effective products.
