Centrifugal glass wool is a porous sound-absorbing material with good sound-absorbing performance. The reason why centrifugal glass wool can absorb sound is not due to its rough surface、 but because it has a large number of small pores and pores connected internally and externally. When sound waves are incident on centrifugal glass wool、 they can enter the interior of the material along the pores、 causing vibrations of air molecules in the pores. Due to the viscous resistance of air and the friction between air molecules and pore walls、 sound energy is converted into heat energy and lost
