Therefore, in places where indoor noise needs to be controlled and acoustic effects need to be improved, such as conference rooms, recording studios, theaters, offices, schools, restaurants, hotels, etc., sound-absorbing panels are usually used for decoration. Sound-absorbing panels can not only beautify the indoor environment, but also improve the overall comfort and user experience. Therefore, in architectural decoration design, sound-absorbing panels are one of the common and important decorative materials.

[0026] Example
[0027] like Figure 1 and Figure 2As shown, the utility model proposes an environmentally friendly polyester fiber low-frequency sound-absorbing board for architectural decoration, comprising a first antibacterial layer 1, a sound-absorbing structure 2, a second antibacterial layer 3, and a surface layer 4 arranged from the inside to the outside. A moisture-proof layer 5 is also arranged on the side of the first antibacterial layer 1 away from the sound-absorbing structure 2. A first adhesive layer 6 is arranged between each of the first antibacterial layer 1, the sound-absorbing structure 2, the second antibacterial layer 3, the surface layer 4, and the moisture-proof layer 5. The first adhesive layer 6 is used to make the two adjacent parts tightly connected to avoid the loosening or falling off of the sound-absorbing material, thereby ensuring the stability and durability of the sound-absorbing effect, and at the same time can increase the mechanical strength of the sound-absorbing board to make it more durable and stable.
[0028] For further information, see Figure 2 and Figure 3 The sound absorbing structure 2 in the above-mentioned sound absorbing board includes a first dispersion layer 21, a first sound absorbing layer 22, a second sound absorbing layer 23, and a second dispersion layer 24 arranged from the inside to the outside, and a second adhesive layer 61 is arranged between the two adjacent parts, and the second adhesive layer 61 also makes the two adjacent parts tightly connected. The first dispersion layer 21 is provided with a plurality of groups of first dispersion holes 211, and the second dispersion layer 24 is provided with a plurality of groups of second dispersion holes 241. The first dispersion holes 211 and the second dispersion holes 241 are arranged in an irregular state, which can increase the number of times the sound is reflected and scattered in the material and improve the sound absorption effect. The first sound absorbing layer 22 is provided with a plurality of groups of first sound absorbing through holes 221 arranged equidistantly and in parallel, and the second sound absorbing layer 23 is provided with a plurality of groups of second sound absorbing through holes 231 arranged equidistantly and in parallel, and the first sound absorbing through holes 221 and the second sound absorbing through holes 231 are perpendicular to each other. It can make the sound waves refract and scatter repeatedly inside the sound-absorbing board, increase the path length of the sound waves propagating in the material, thereby improving the absorption and attenuation of the sound waves. At the same time, it will increase the flow resistance of the air inside the sound-absorbing board, enhance the air damping effect, further improve the sound absorption performance, effectively enhance the absorption capacity of low-frequency sound, and make the sound absorption effect of the sound-absorbing board in the low-frequency band more significant.
[0029] Specifically, the first antibacterial layer 1 and the second antibacterial layer 3 are both made of ramie fiber material, which has good acoustic properties, can enhance the overall sound absorption performance of the sound-absorbing board, can effectively absorb and disperse sound waves, and help achieve sound absorption in a wider frequency band. Since ramie fiber itself has natural antibacterial properties, it can effectively inhibit the growth and reproduction of bacteria. Therefore, the application of ramie fiber in the sound-absorbing board helps to reduce the growth of bacteria on the surface of the sound-absorbing board, thereby improving the sanitation level of the indoor environment. The surface layer 4 is made of bamboo fiber material. Bamboo fiber has a microporous structure and a large specific surface area, which is conducive to absorbing and dissipating sound waves, thereby improving the sound absorption performance of the sound-absorbing board and effectively reducing noise. At the same time, the natural texture and color give people a natural and fresh feeling, which can enhance the decorative effect of the sound-absorbing board and increase the beauty of the indoor space. The moisture-proof layer 5 is made of rock wool material. Rock wool itself is not easy to absorb water, and will not deform or rot due to moisture. It has good moisture-proof performance. The use of rock wool on the sound-absorbing board can effectively prevent moisture from eroding the internal materials of the sound-absorbing board and extend the service life of the sound-absorbing board. The first dispersion layer 21, the first sound-absorbing layer 22, the second sound-absorbing layer 23, and the second dispersion layer 24 are all made of polyester fiber material. Polyester fiber has a high sound absorption coefficient and can effectively absorb and dissipate sound waves, improve the sound absorption effect of the sound-absorbing board, and reduce noise transmission. At the same time, it is easy to process and can adapt to various shapes and design requirements. In addition, the above-mentioned ramie fiber, bamboo fiber, rock wool and polyester fiber are all environmentally friendly materials.
[0030] In this embodiment, when in use, the ramie fiber material used in the first antibacterial layer 1 and the second antibacterial layer 3 has good acoustic performance, can enhance the overall sound absorption performance of the sound-absorbing board, can effectively absorb and disperse sound waves, and help achieve sound absorption in a wider frequency band. In addition, since the ramie fiber itself has natural antibacterial properties, it can effectively inhibit the growth and reproduction of bacteria, which helps to reduce the growth of bacteria on the surface of the sound-absorbing board, thereby improving the sanitation level of the indoor environment. The bamboo fiber material used in the surface layer 4 has a microporous structure and a large specific surface area, which is conducive to absorbing and dissipating sound waves, thereby improving the sound absorption performance of the sound-absorbing board and effectively reducing noise. At the same time, the natural texture and color give people a natural and fresh feeling, which can enhance the decorative effect of the sound-absorbing board and increase the beauty of the indoor space. The rock wool material used in the moisture-proof layer 5 is not easy to absorb water, and will not deform or rot due to moisture. It has good moisture-proof performance. Using rock wool on the sound-absorbing board can effectively prevent moisture from eroding the internal materials of the sound-absorbing board and extend the service life of the sound-absorbing board. The first dispersion layer 21, the first sound absorption layer 22, the second sound absorbing layer 23, and the second dispersion layer 24 are made of polyester fiber materials. Polyester fiber has a high sound absorption coefficient, can effectively absorb and dissipate sound waves, improve the sound absorption effect of the sound absorbing board, reduce noise transmission, and is easy to process and can adapt to various shapes and design requirements. In addition, the above-mentioned ramie fiber, bamboo fiber, rock wool and polyester fiber are all environmentally friendly materials, which can bring multiple benefits such as sustainability, low carbon emissions, good sound absorption effect, durability, safety, health and environmental protection.
[0031] The above specific embodiment is only an optional embodiment of the present invention.
