Do you know the functional role of wooden sound-absorbing boards?

1. Basic specifications for the appearance of wooden sound-absorbing boards
Wooden sound-absorbing boards are usually made of medium density boards, high-density boards, Australian pine boards, or fire-resistant boards with a thickness of 9mm, 12mm, 15mm, or 18mm. The surface of the wooden sound-absorbing board has melamine or solid wood veneer, baked paint surface, and so on. According to the different openings of wooden sound-absorbing boards, they can be divided into two types: grooved sound-absorbing boards and perforated sound-absorbing boards. Among them, grooved sound-absorbing boards are a type of resonant sound-absorbing material with narrow slots on the front and perforated on the back of density boards, while perforated sound-absorbing boards are a structural sound-absorbing material with circular holes on both the front and back of the board, with non-woven sound-absorbing cloth pasted on the back.
2. Sound absorption performance of wooden sound-absorbing boards
Wooden sound-absorbing boards are usually coated with a layer of pentagonal sound-absorbing cloth when leaving the factory, which has a certain sound-absorbing effect. As long as there is a certain thickness of cavity left behind during installation, it should be used as a separate sound-absorbing material, with medium and low frequency sound-absorbing characteristics. If a certain thickness of porous sound-absorbing materials, such as glass wool, polyester fiber sound-absorbing cotton, melamine sound-absorbing cotton, etc., are filled in the cavity, it can effectively improve the medium and high frequency sound-absorbing performance of the entire structure.
3. Installation method of wooden sound-absorbing board
Wooden sound-absorbing panels can usually be used for walls and ceilings. When used on walls, attention should be paid to retaining a certain thickness of cavity, that is, the sound-absorbing board has a certain distance from the solid wall. Therefore, when installing, a layer of keel needs to be installed on the wall first, filled with sound-absorbing cotton. If a wooden keel is used, the wooden sound-absorbing board can be fixed on the keel with nails. If a light steel keel is used, the wooden sound-absorbing board can be fixed on the keel with locking steel clips.
4. Other performance and decorative effects
If wooden sound-absorbing panels are selected with fire-resistant materials, they can generally achieve flame retardant and fire-resistant levels. The decorative effect of wooden sound-absorbing boards is good, and various colors can be used on the surface, such as maple, beech, walnut, oak, teak, and other series, to achieve a good wooden decorative effect.
