Sichuan wall panel supplier introduces the sound absorption principle of sound absorption materials of surface panel: sound originates from the vibration of objects, which causes the vibration of adjacent air to form sound waves and propagates in the air environment. When the sound reaches the surface of the component material, part of the sound energy is reflected, part of it penetrates the material, and part of it is converted into heat energy and lost due to the vibration of the component material or the friction between the sound and the surrounding medium. That is, sound is usually absorbed by materials.
Sound insulation is very important, which requires us to choose suitable sound-absorbing materials in decoration.
