1 wooden sound absorbing panel The wooden sound absorbing panels are exquisitely processed according to the acoustic principle and consist of a facing, a core material and a sound absorbing felt. The wooden sound absorbing panels are divided into two types: a wooden sound absorbing panel and a hole wood sound absorbing panel. 2 mineral wool sound absorbing panels The surface treatment of mineral wool sound absorbing panels is rich, and the panels have strong decorative effects. The surface treated knurled mineral wool board, commonly known as "caterpillar", is covered with holes of different depth, shape and aperture. 3 fabric sound absorbing panels Fabric sound absorbing panels - the core material is centrifugal glass wool. Centrifugal glass wool, as an acoustic material that has been widely used throughout the world, has been proven to have excellent sound absorption properties. 4. Polyester fiber sound absorbing panel Polyester fiber sound absorbing panels are an ideal sound absorbing decorative material. Its raw material is 100% polyester fiber, which has sound absorption, environmental protection, flame retardant and heat insulation. Polyester fiber sound absorbing panels are used for heat preservation, moisture proof, mildew resistance, easy dust removal, easy cutting, can be parquet, simple construction, good stability, impact resistance, good independence, high cost performance, etc. Choices to meet the needs of different styles and levels of appealing decoration. Products are widely used in: conference rooms, TV stations, studios, theaters, audio-visual rooms, opera houses, leisure and entertainment cities, hotels, multi-function halls, concert halls, bars, restaurants, shopping malls, schools, auditoriums, stadiums, KTV, etc. . 5 metal sound absorbing panels The metal sound absorbing panel is mainly provided with a triangular pyramid having a plurality of conical bottoms and an elliptical micropore on the bottom surface of the metal plate body, and a micro wave surface formed on the top surface of the metal plate body, and the wave surface is formed on the wavy surface. A shaped triangular pyramid is also recessed around the upper portion of the corresponding elliptical micropores; accordingly, the reflected acoustic waves collide with each other to cause attenuation, and at the same time, even if part of the acoustic waves will penetrate the elliptical micropores at the bottom of the triangular pyramid cone, Causes sound wave penetration loss for better sound absorption and faster assembly. It combines the advantages of “green, durable, beautiful, sound-absorbing, sound-proof, easy to install and useâ€, which is widely used in studios, theaters, multi-purpose halls, conference rooms, etc. Some public places such as concert halls and classrooms. 6 ceramic aluminum decorative sound absorbing panels Ceramic aluminum non-combustible sound-absorbing decorative board. Using a combination of a variety of different inorganic materials, inorganic materials as the main material, by adding conductive ceramic powder, conductive mica powder and other conductive materials, reinforcing fibers and other materials, using inorganic binder bonding, natural curing method made of special The board is then combined with a variety of different decorative materials on its surface to provide melamine high-pressure decorative laminates (commonly known as fireproof decorative panels), natural veneer, metal and other materials. The decorative effect is perfect and can meet different decorative environments. Thereby forming different decorative effects. The technical principle of sound absorption is as follows: First, a porous structure is formed in the material itself to achieve a certain sound absorption effect, and the second is to form a perforated plate resonance structure on the finished plate by slotting and drilling to achieve a sound absorption effect. And with the sound-absorbing non-woven fabric to further enhance the sound absorption effect. The material is A1 grade non-combustible material.
