Selection of Acoustic Panels Materials

Selection of Acoustic Panels materials
There are many types of indoor Acoustic Panels materials, such as grooved wood Acoustic Panels, perforated wood sound-absorbing panels, fabric soft-packed sound-absorbing panels, polyester fiber sound-absorbing panels, wood wool sound-absorbing panels, sound insulation materials, sound insulation blankets, etc.
1. The grooved wood Acoustic Panels board is developed and manufactured according to the acoustic principle, with holes on the back and grooved on the surface. It has excellent noise reduction and sound absorption characteristics, and is particularly effective for medium and high frequency sound absorption. All the raw materials used are in line with the environmental protection level, the formaldehyde concentration is extremely low, and the products also have the fragrance of wood.
2. The perforated wood Acoustic Panels board has all the cylindrical holes running through the back and back of the high-density board. The backing material with air permeability and the Acoustic Panels material that can digest and absorb the emitted sound are assembled on the back of the high-density board. The principle of sound absorption is that there are many finely connected porosity inside the raw material. The sound wave frequency can go deep inside the raw material along with this porosity, and generate friction with the raw material to convert the sound into energy. The sound absorption feature of the porous structure sound-absorbing material is that the sound absorption index gradually expands with the increase of the frequency, which means that the high-frequency digestion and absorption are not as good as the high-frequency digestion and absorption. The sound-absorbing principle of this kind of structure is the sound absorption of metal thin plates. At the natural frequency, due to the strong vibration of the metal sheet, a lot of sound is digested and absorbed.
3. Fabric Acoustic Panels are always available in a variety of shades and designs of veneer cloths to choose from, or customers can show veneer cloths. The fabric Acoustic Panels has a high sound-absorbing band, which has a good sound-absorbing effect on low, medium and high frequency noise. It has the characteristics of flame retardant and fire safety, dust-producing environmental pollution, strong decorative art, and simple engineering construction.
 4. Polyester fiber Acoustic Panels decorative panels have the functions of sound absorption, noise reduction, noise reduction, thermal insulation, thermal insulation, etc. The material is well-proportioned and reliable, not only has ductility, ductility, wear resistance, impact resistance, and is not easy to landslides , it has a good effect on the co-vibration sound-absorbing body composed of the metal sheet with the inner cavity, and is a high-efficiency sound-absorbing material with a wide screen. It is a new type of acoustic material that replaces the past multi-layer board plus sponge or glass fiber, and it is easy to destroy without environmental pollution, and can be reused in the recycling system.
