What material is perforated sound-absorbing board made

Sound is produced by the vibration of the object, the sound through the air after the formation of sound waves, when the sound through the surface layer of the object, part of the sound is reflected back by the surface of the object, but the other part of the sound can penetrate the material, while the other part is through friction with the object and the sound energy into heat energy. So the sound energy is lost, I .e. the sound is absorbed. What material is used for the perforated sound-absorbing board?

The perforated sound-absorbing board has cylindrical holes running through the front and back sides of the honeycomb aluminum panel, is bonded to the back of the honeycomb aluminum panel, and is composed of sound-absorbing materials that can absorb sound energy. According to the indoor sound quality design, different perforation design can be carried out, and the sound absorption coefficient of the combined structure can be controlled within a certain range to achieve the design effect. The invention adopts high-quality non-woven fabric and other sound-absorbing materials, by controlling the perforation aperture, hole distance, and can adjust the perforation rate according to customer needs, the maximum perforation rate of 30%, the back plate perforation requirements are consistent with the panel, and the sound-absorbing cloth adopts high-quality non-woven fabric.

It is made of alloy raw materials, with beautiful perforation, innovative hole array design, unique seamless continuous perforation layout, high-performance sound-absorbing solutions combined with quality and beauty, ceiling system has unlimited designability and great flexibility.
