The vibration of the object produces sound → sound waves are transmitted in the air, → Soundproof Insulation Fiber Glass Wool,Heat Resistant Rubber Insulation Cotton → sound waves are reflected, superimposed and collided by countless fibers when passing through cotton, and sound energy is converted into heat energy → sound intensity is weakened → sound disappears. The transmitted sound energy is attenuated to 3 / 10 ~ 4 / 10 or less of the incident sound energy.
