High Density CEILLING Decoration Durable Polyester Fiber

High Density CEILLING Decoration Durable Polyester Fiber   Polyester fiber panel has wide-band and high-efficiency sound absorption characteristics, and is a star product in architectural acoustics and industrial noise reduction projects. Its sound absorption principle is similar to that of porous materials. The sound is effectively absorbed through the fiber structure, especially in the high-frequency band. The overall noise reduction performance is further improved by leaving a space at the back, and the noise reduction coefficient reaches 0.8-1.10. It is widely used in high-noise environments such as workshops, soundproof cabins for engineering machinery and equipment, and mines. This felt wall panels not only ensure the comfort of the working environment, but also protect the hearing health of the staff. It is one of the indispensable solutions for modern industrial acoustics.     Product Features   With an NRC value of 0.9, it can effectively absorb mid- and high-frequency soun…
