Anonymous users2024-01-23Sound-absorbing materials are the general term for all products with sound-absorbing properties, and all products with sound-absorbing properties can be called sound-absorbing materials.
Most of the sound-absorbing materials are loose and porous materials, such as slag wool, blankets, etc., and their sound-absorbing mechanism is that the sound waves penetrate deep into the pores of the material, and the pores are mostly open pores that penetrate each other inside, which are subject to the friction and viscous resistance of air molecules, as well as the mechanical vibration of fine fibers, so that the sound energy is converted into heat energy. The sound absorption coefficient of this kind of porous sound-absorbing material generally increases gradually from low frequency to high frequency, so the sound absorption effect of low frequency is not ideal.
