Sound Acoustic Noise Barrier

  Product DescriptionTarget Noise Frequency RangeFrom 300 to 10000HzCross-sectional Shape SquareMaterialCustomized, Aluminum, Steel, Plastic, etc.Insertion LossCustomized, From 10dB to 30dBDetailed Photos Installation InstructionsAs shown in the video, the arch shaped ventilation shield forms an all-round noise barrier to complete block the noise escaping route in all directions, while maintaining fresh air circulation on the highway by natural air flow. This is particularly good news for people on the high floor in nearby tall buildings, where conventional solid noise barriers of up to 3 meters high are still unable to provide sufficient noise shield.For more technical information about individual types of ventilation silencer, please visit our official website.Our AdvantagesThe noise attenuation power of our products is much higher than competitors, especially in the frequency range below 500 Hz.We can design and tailor-make products for specific frequency bands and air flow demands. Being meta-materials, a wide range of constituent materials can be selected for our products to meet stringent environments, such as high/low temperatures, high humidity, corrosive surrounding, fire safety requirements, etc.  FAQQ. Do you provide custom-made products?A. Yes, we provide design solutions and products to meet the specific needs of our customers.Q. Why can't I find similar products elsewhere?A. Our products are based on the proprietary locally resonant sonic metamaterials invented by our company founder, which is unique and well advanced and disruptive.Q. I do not have much knowledge about noise mitigation, and do not quite know what products to purchase.A. Contact us and tell us your noise problem. We will provide the solutions and the products./* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
