Description

Technical Field

[0001] The utility model relates to the technical field of building materials, and particularly relates to a perforated sound-absorbing board. Background Technique

[0002] A perforated sound-absorbing board is a special board with the function of sound absorption and noise reduction. Its sound absorption effect is mainly achieved through the small holes on its surface. When sound waves encounter the perforated sound-absorbing board, the sound waves will enter these small holes and generate friction and damping inside the holes, thereby reducing the reflection and propagation of sound energy and achieving the purpose of sound absorption. The sound absorption performance of the perforated sound-absorbing board is closely related to factors such as the aperture, hole pitch, hole depth, and material thickness of the board. Generally speaking, the smaller the aperture, the denser the hole pitch, and the shallower the hole depth, the better the sound absorption effect. At the same time, the material of the perforated sound-absorbing board also affects the sound absorption effect. Commonly used materials include wood, mineral wool, fabric, polyester fiber, etc. In addition to the sound absorption performance, the perforated sound-absorbing board also has a decorative function, which can be coordinated with the interior decoration style to improve the overall aesthetics. At the same time, the perforated sound-absorbing board also has advantages such as fire prevention and environmental protection, and can meet the use requirements of different places.

[0003] The authorized publication number "CN209293336U" records "a sound-absorbing board. A microporous sound-absorbing board in the utility model includes a substrate layer and a decorative surface layer provided on the substrate layer. The substrate layer is made of a sound-absorbing material, and a plurality of substrate holes are provided on the substrate layer. The decorative surface layer is provided with decorative holes at positions corresponding to the substrate holes, and the diameter of the decorative holes is smaller than the diameter of the substrate holes. After the noise enters the substrate holes from the decorative holes, due to the fact that the substrate holes are larger than the diameter of the decorative holes, the noise adsorption effect is good".
