Wood sound-absorbing board
The wood sound-absorbing board is finely processed according to the acoustic principle, and consists of veneer, core material and sound-absorbing thin felt. There are two kinds of wooden sound-absorbing boards: slotted wooden sound-absorbing boards and perforated wooden sound-absorbing boards.
Mineral wool sound-absorbing board
The surface treatment forms of mineral wool sound-absorbing board are rich, and the board has a strong decorative effect. The knurled mineral wool board with treated surface, commonly known as "caterpillar", is covered with holes with different depths, shapes and apertures.
Fabric sound-absorbing board
Fabric Acoustic Panel-The core material is centrifugal glass wool. Centrifugal glass wool, as an acoustic material that has been widely used all over the world, has been proved to have excellent sound absorption performance.
Polyester fiber sound-absorbing board
Polyester fiber sound-absorbing board is an ideal sound-absorbing decorative material. Its raw material is 100% polyester fiber, which has the advantages of sound absorption, environmental protection, flame retardant, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, easy mosaic, simple construction, good stability, good impact resistance, good independence and high cost performance. There are many colors to choose from, which can meet the attractive decoration needs of different styles and levels.
Metal sound-absorbing board
The metal sound-absorbing board is mainly characterized in that a plurality of triangular cones with elliptical micropores are densely recessed at the bottom of the metal plate body, a microwave surface is formed on the top surface of the metal plate body, and triangular cones are also recessed around the upper part of the wave surface corresponding to the elliptical micropores; Accordingly, the reflected sound waves collide and interfere with each other to produce attenuation, and at the same time, even if some sound waves penetrate the elliptical micropores at the bottom of the triangular cone, it will also cause sound wave penetration loss.
In order to achieve better sound absorption and faster assembly effect. It perfectly combines the advantages of modern architectural concepts such as "environmental protection, durability, beauty, strong sound absorption, good sound insulation effect and convenient installation and use", and is widely used in some public places such as studios, theaters, multi-function halls, conference rooms, concert halls and classrooms. Ceramic aluminum decorative sound-absorbing board
Ceramic aluminum incombustible sound-absorbing decorative board. The combination of different inorganic materials, mainly inorganic materials, adding conductive materials such as conductive porcelain clay powder and conductive mica powder, reinforced fibers and other materials, adopting the method of inorganic adhesive bonding and natural curing, and then compounding different decorative materials on their surfaces, can provide melamine high-pressure decorative laminates (commonly known as fire-resistant decorative boards), natural wood skins, metals and other materials, and the decorative effect is perfect, which can meet different decorative environments.
The technical principle of sound absorption is as follows: firstly, a porous structure is formed in the material itself to achieve a certain sound absorption effect; Secondly, the vibration structure of perforated plate is formed by slotting and drilling holes on the finished plate to achieve sound absorption effect. Adding sound-absorbing non-woven fabric, the sound-absorbing effect is further improved. The material is A 1 incombustible material. After understanding the sound-absorbing board, it is easy to choose the sound-absorbing board that suits you according to your own economic situation and actual needs. Generally, the higher the sound absorption capacity, the higher the price of sound-absorbing board, but the sound absorption capacity should not be less than 30dB.
