- product introduction:The sound-absorbing material is used to absorb noise. The sound-absorbing material is a loose and porous structure. The sound wave enters the pores and causes a small vibration. Due to friction and viscous resistance, a considerable part of the sound energy is absorbed after being converted into thermal energy. Passive rooms are generally used in large quantities.
