Mistakenly think that if you can put up with the sound absorbing effect of sound-absorbing material in some configurations will be renovated porous sound-absorbing material placed behind plywood or plasterboard panels, sound-absorbing material such cases will not achieve the role of sound absorption. Because the primary condition of the porous sound-absorbing material is acoustic energy into the interior of the material, and this structure so that the sound absorption material is blocked in front of the plate reflected back soft bag manufacturer, can not enter into the interior of the material, it can not be played the sound-absorbing effect. If the front plate is thin, hollow plate after relatively large soft bag wholesale, can be used as sound absorbing sheet structure. In this case, if some of the porous sound-absorbing material filling soft pack sound-absorbing panels in the cavity, you can increase the width of the band's sound-absorbing soft package structure, but this time porous sound-absorbing material can only play a supporting role in sound absorption, is not the main effect, the absorption effect can not be exposed to the sound field in comparison with the case of sound-absorbing material.
