Polyester fiber acoustic panels are common and widely used sound-absorbing materials. It has the characteristics of non-toxic, tasteless and environmental protection. According to different needs, shorten and adjust the reverberation time, remove sound impurities, improve sound effects, and improve language clarity. The products have the characteristics of decoration, heat preservation, flame retardant, environmental protection, light weight, easy processing, stability, impact resistance, and easy maintenance. It has become the first choice of decorative sound-absorbing material for interior decoration.

What is polyester fiberboard?

The polyester fiber board is made by high heat pressing technology, and it is in the shape of cocoon cotton. It can insulate the noise within the noise range of 125-4000HZ, and the sound insulation coefficient is above 0.9. The sound insulation of polyester fiberboard is not only strong in sound insulation, but also decorative, green and environmentally friendly, easy to clean, and becomes the first choice for decorative sound insulation and sound-absorbing materials during decoration.

Features of polyester fiber sound-absorbing panels:

1. Sound absorption

Similar to the sound absorption characteristics of other porous materials, the sound absorption coefficient of polyester fiber sound-absorbing panels increases with the increase of sound frequency. Sound impurities, improve the sound effect, improve the clarity of speech. Among them, the space sound-absorbing body greatly improves the sound-absorbing performance of the material, and is a high-efficiency sound-absorbing body with a wide frequency band. It is widely used in theaters, concert halls, indoor gymnasiums, conference rooms, HV, hotels, family audio-visual rooms and other places with high acoustic requirements.

2. Independent quickness

There is no need for sound-absorbing cotton, no decorative boards, or even auxiliary materials, and the desired sound-absorbing and decorative effects can be achieved through simple basic operations such as sticking, drilling, planing, and ruthenium. Reduce the overall project cost and construction period.

3. Physical properties

Polyester fiber sound-absorbing panel is a kind of fiber similar to clothing, which itself has the characteristics of heat insulation. After forming the board, it has the characteristics of elasticity, toughness, wear resistance, impact resistance, tear resistance, not easy to be scratched, and large board width (2420inmX1220inm; 2440mmX 1220mm). Bofu polyester fiber sound-absorbing panels are ideal materials for decoration.

The sound-absorbing principle of polyester fiberboard: there are a large number of tiny interconnected pores inside the material, and sound waves can penetrate deep into the material along these pores, and rub against the material to convert sound energy into heat energy. It is a porous sound-absorbing material, and the sound-absorbing characteristic is that the sound-absorbing coefficient gradually increases with the increase of the frequency, which means that the low-frequency absorption is not as good as the high-frequency absorption
