In the field of acoustic design, polyester fiber sound-absorbing panels are one of the common sound-absorbing materials. This article will introduce you in detail to the characteristics, working principles and application fields of polyester fiber sound-absorbing panels.
Material structure: Polyester fiber sound-absorbing panels are made of high-tech hot-pressed fine polyester fiber filaments, which are naturally porous and usually present a uniform and dense fiber structure. They can replace harmful traditional sound-absorbing materials such as sponges, glass wool, and rock wool. Plate

Material characteristics of polyester fiber sound-absorbing panels：
1. Efficient and stable sound-absorbing performance
The working principle of polyester fiber sound-absorbing panels is based on the absorption and scattering of sound waves. When sound waves hit the surface of the sound-absorbing panels, part of the sound energy is absorbed by the fiber material, converted into tiny particles, and converted into heat energy through friction. At the same time, the fiber structure of the sound-absorbing panel will also scatter part of the sound waves, causing them to undergo multiple reflections, thereby extending the propagation path of the sound waves in the material and increasing energy loss. This combination of absorption and scattering reduces sound reverberation and noise dispersion. In the noise range of 125~4000HZ, the highest sound absorption coefficient reaches more than 0.8 (depending on the structure)

2. The material is evenly insulated.
The overall texture of polyester fiber sound-absorbing panels is solid and wear-resistant, not prone to scratches or scratches, and is highly elastic. It is precisely because of its characteristics that polyester fiber sound insulation panels have very good performance in heat insulation and sound absorption, and can maintain their sound absorption performance for a long time.
3. The material is easy to process and the design is diverse.
Polyester fiber sound-absorbing panels are easy to cut and process, and can be adjusted in shape and size as needed. The grooved surface finish can be customized into a variety of pattern arrangements, and there are countless patterns that can be combined. You can freely combine and match according to everyone's preferences or needs.

4. Excellent environmental protection and fire protection performance
Polyester fiber sound-absorbing panels are widely used in public places such as gymnasiums, cinemas, and auditoriums. As we all know, these public places have very strict requirements for fire protection and environmental protection, and polyester fiber sound-absorbing panels fully comply with national fire protection standards and environmental protection. The combustion performance reaches B1 level and the environmental protection performance reaches E1 level.

As an important part of acoustic design, polyester fiber sound-absorbing panels have become an ideal choice for acoustic improvement in various places with their excellent sound absorption performance and wide range of applications. Whether it is a conference room, theater, recording studio or other places, polyester fiber sound-absorbing panels can create a high-quality acoustic environment for people, providing comfort and quality listening experience.
