What exactly is a sound-absorbing panel? In fact, it is made of facing, core material and sound-absorbing felt as raw materials, and then processed according to acoustic principles. At present, there are wooden sound-absorbing panels, fabric sound-absorbing panels, polyester fiber sound-absorbing panels, mineral wool sound-absorbing panels, metal sound-absorbing panels and so on. Since there are many small holes on its surface, when sound enters the small holes, it will be reflected randomly in the inner wall until most of the sound wave energy is consumed, thus achieving a sound insulation effect, especially for frequencies higher than 600hz. Sound waves have a very significant effect.
