Noise reduction characteristics of fiber fabric air duct

The wall of the fabric air duct is a flexible fiber fabric, which is itself a bad conductor and absorber of sound, does not produce sound itself, and can also absorb equipment noise to a certain extent. With the extension of the pipeline, the effect is more obvious, and the special muffler can be eliminated.



First, the sound reduction principle of fiber fabric air duct


· Sound absorption properties of fiber materials. The tube wall is a flexible fiber fabric, itself is a bad conductor and absorber of sound, it does not produce sound itself, but also absorbs equipment noise to a certain extent, with the extension of the pipeline, the effect is more obvious, can eliminate the special muffler.


· Airflow dispersion and mitigation. Its internal structure design can make the air flow evenly dispersed, slow down the speed of the air flow, and reduce the noise caused by the turbulent air flow.


Second, the advantages of fiber fabric air duct noise reduction performance


The noise reduction effect is remarkable. It can reduce the noise generated by the ventilation system by 20-30 dB and provide a quiet environment indoors.


Broadband silence. It has a good noise reduction effect on different frequencies of sound, whether it is low frequency wind or high frequency mechanical noise.


Adapt to complex environments. In the environment with large changes in humidity and temperature, the noise reduction performance is still stable and reliable.


Third, the comparison with the traditional air duct


Material differences. The iron sheet air duct is made of metal, and the sound reflection is strong, which is easy to produce resonance and noise; Fabric The soft fibers of an air duct absorb sound.


Structural comparison. The iron duct is mostly rigid structure, and the air flow impact produces large noise. The flexible structure of fiber fabric air duct can buffer airflow and reduce noise.


Installation impact. The interface and connection parts of the iron duct are easy to produce air leakage and noise during installation. Fiber fabric air duct is easy to install, good sealing, reduce the noise source.


4. Practical scenarios


Fiber fabric air ducts are widely used in medicine, food, machinery and electronics, shopping malls, supermarkets, sports centers, exhibition halls and other places. Choosing fiber fabric air duct is to choose a professional air supply solution to create a quiet and comfortable space environment for you.
