They not only cause distractions but also directly impact health. This article...,&nbsp;<strong>Vietnamese Stars<\/strong>&nbsp;will share the secrets to choosing.&nbsp;<strong>duct soundproofing material<\/strong>&nbsp;Optimized to help you create a peaceful and energy-efficient space.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. Why is soundproofing air ducts an essential step?<\/h2>\n\n\n\n<p>Investing in soundproofing systems from the outset offers a double benefit to the developer:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Eliminate noise pollution:<\/strong>&nbsp;Minimize noise caused by high-speed airflow and mechanical vibrations in the HVAC system.<\/li>\n\n\n\n<li><strong>Productivity optimization:<\/strong>&nbsp;A quiet environment helps increase the concentration ability of office workers and factory workers.<\/li>\n\n\n\n<li><strong>Protect your health:<\/strong>&nbsp;Reduce stress and fatigue and improve sleep quality for civil engineering projects.<\/li>\n\n\n\n<li><strong>Economic benefits (2 in 1):<\/strong>&nbsp;Most soundproofing materials available today are capable of...&nbsp;<strong>insulation<\/strong>, This helps to minimize heat loss, significantly saving on electricity costs for air conditioning.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2025\/08\/Ong-gio-sao-viet-3-1-1024x768.jpg\" alt=\"\" class=\"wp-image-5087\" srcset=\"https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2025\/08\/Ong-gio-sao-viet-3-1-1024x768.jpg 1024w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2025\/08\/Ong-gio-sao-viet-3-1-300x225.jpg 300w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2025\/08\/Ong-gio-sao-viet-3-1-768x576.jpg 768w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2025\/08\/Ong-gio-sao-viet-3-1-16x12.jpg 16w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2025\/08\/Ong-gio-sao-viet-3-1-600x450.jpg 600w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2025\/08\/Ong-gio-sao-viet-3-1.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">2. Listing the 4 most common types of duct soundproofing materials.<\/h2>\n\n\n\n<p>Depending on the specific characteristics of the project, each type of material will offer its own advantages. Below is a comparison table to help you make an informed choice:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2.1. Mineral wool (Rockwool) \u2013 The &quot;Champion&quot; of heat resistance<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Advantage:<\/strong>&nbsp;Excellent sound absorption capabilities, superior fire resistance, and high temperature resistance.<\/li>\n\n\n\n<li><strong>Application:<\/strong>&nbsp;Priority should be given to ventilation systems in factories, furnaces, or areas with a high risk of fire or explosion.<\/li>\n\n\n\n<li><strong>Note:<\/strong>&nbsp;An additional layer of fiberglass or sheet metal should be used as a protective covering to prevent the dispersal of fine dust.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2.2. Glasswool \u2013 An economical solution<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Advantage:<\/strong>&nbsp;Lightweight, highly elastic, and cheaper than mineral wool.<\/li>\n\n\n\n<li><strong>Application:<\/strong>&nbsp;Suitable for soundproofing air ducts in office buildings and shopping malls.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2.3. Vulcanized rubber (EPDM\/Nitrile) \u2013 Absolutely moisture-resistant<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Advantage:<\/strong>&nbsp;The closed-cell structure provides excellent sound insulation, moisture resistance, mold resistance, and exceptional durability.<\/li>\n\n\n\n<li><strong>Application:<\/strong>&nbsp;The number one choice for cleanrooms, hospitals, or high-humidity environments.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2.4. Acoustic Panels \u2013 The pinnacle of aesthetics<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Advantage:<\/strong>&nbsp;Beautiful, modern design, easy to install on the inside or outside of the air duct.<\/li>\n\n\n\n<li><strong>Application:<\/strong>&nbsp;Often used in open spaces requiring high aesthetic appeal, such as studios and movie theaters.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">3. The &quot;golden&quot; criteria when choosing sound-absorbing materials for ventilation systems.<\/h2>\n\n\n\n<p>To achieve the best results at the lowest cost, keep the following three criteria in mind:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>NRC (Noise Reduction Coefficient) index:<\/strong>&nbsp;The closer the sound absorption coefficient is to 1.0, the higher the soundproofing efficiency.<\/li>\n\n\n\n<li><strong>Material thickness:<\/strong>&nbsp;Typically, a thickness of 25mm to 50mm is ideal for suppressing mid- and low-frequency noise.<\/li>\n\n\n\n<li><strong>Installation location:<\/strong>&nbsp;Internal lining helps to directly absorb sound from the airflow, while external wrapping reduces noise transmitted through the duct shell.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">4.
