In modern buildings, the comfort of the indoor environment depends not only on temperature, humidity and air quality, but also on noise control, which is an important factor affecting the living and working experience. The ventilation system is the core of air circulation in the building, and the choice of its duct material directly affects the propagation of noise. As a new type of environmentally friendly building material, magnesium air duct has outstanding performance in reducing duct noise with its excellent sound insulation, noise reduction and sound absorption performance, providing a quieter indoor environment for the building.1. The main source of duct noiseIn the building ventilation system, duct noise usually comes from the following aspects:Air flow noise: The high-speed airflow inside the duct will produce turbulent noise, especially at high wind speeds or at pipe bends.Equipment vibration noise: When the fan, air conditioner and other equipment are running, it will cause the duct resonance, so that the noise will be transmitted to each room through the duct.Structural transmission noise: Metal ducts are prone to transmit noise along the pipe wall, affecting the quietness of adjacent spaces.Traditional air ducts (such as galvanized iron air ducts) tend to amplify these noises due to their metallic properties, while magnesium air ducts have obvious advantages in noise control.2. How does magnesium air duct reduce building noise?(1) Excellent sound insulation performance of magnesium materialsMagnesium air ducts are made of magnesium composite materials (such as magnesium oxide-based materials). This material has a high density and a uniform internal structure, which can effectively block the spread of noise. Compared with traditional metal air ducts, it can reduce aerodynamic noise and structure-borne noise, making the interior of the building quieter.(2) Reduce air flow noiseThe smoothness of the inner wall of the air duct directly affects the friction noise generated when the air flows. Magnesium air ducts usually have a smoother inner wall, which can reduce the turbulent effect of air flow and make the wind speed distribution more uniform, thereby reducing wind noise. In addition, its low sound conductivity can prevent the air from echoing in the duct and improve the noise control effect.(3) Reduce resonance and structure-borne noiseDuring the operation of the ventilation system, the vibration of equipment such as the fan may be transmitted along the duct, causing noise to spread. Metal air ducts are more rigid and prone to resonance and amplification of vibration noise. Magnesium air ducts have higher damping properties and can effectively absorb vibration energy, reduce resonance, and thus reduce noise transmission.(4) Excellent sound absorption effectMagnesium air duct materials themselves have a certain sound absorption capacity, especially for medium and high frequency noise. Therefore, in environments with high requirements for sound control (such as schools, hospitals, offices, etc.), magnesium air ducts can effectively reduce the noise interference caused by the ventilation system and improve the quietness of the space.(5) Reduce external noise interferenceMagnesium air duct can not only reduce the noise generated by itself, but also block external noise, such as traffic noise, equipment room noise, etc. Its dense structure gives it an excellent sound shielding effect, preventing external noise from entering the room through the air duct, thereby maintaining the quietness of the space.3. Practical application of magnesium air ductDue to its excellent noise reduction effect, magnesium air duct is widely used in multiple building types:Residential buildings: reduce the noise of fans and air conditioning systems and improve living comfort.Office buildings: Provide a quiet working environment and reduce the noise impact of ventilation systems on conference rooms and offices.Schools and hospitals: In places with high noise control requirements, magnesium air duct helps create a quiet learning and treatment environment.Hotels and commercial buildings: Improve user experience and let guests enjoy a quieter space.Magnesium air duct can effectively reduce the noise pollution caused by the ventilation system with its excellent sound insulation, sound absorption and noise reduction characteristics, making the internal environment of the building quieter and more comfortable. Compared with traditional metal air ducts, magnesium air duct performs better in reducing air flow noise, reducing structure-borne noise, reducing vibration resonance, and isolating external noise. Therefore, in construction projects that pursue high-quality indoor environments, magnesium air duct is undoubtedly an ideal choice.
