Soundproof fabric is a type of material specifically designed to block the transmission of sound, typically characterized by high density and weight. Soundproof fabric primary function is to absorb or block sound waves, reducing the propagation of noise to achieve soundproofing effects. The heavier the material, the better the soundproofing effect. The higher the density of the soundproof fabric, the stronger its ability to block sound waves. The fibers within the soundproof fabric create a damping effect on sound waves, reducing their energy.
