sound insolution damping materials and Sandwiched high polymer damping materials

详情

OFF compound sound insulation board is made of more than three layers of materials with different densities and properties, is sandwiched with high polymer damping materials to change the sound and vibration frequencies of original material, and adopts the sandwich structure to perform high-pressure composite molding to form the constrained damping structure. The acoustic wave energy penetrating through the wall system can be reduced by over *5% to the maximum.
When the sound insulation board starts vibrating under the impact of sound wave, the high polymer material in the middle of the board continuously bears the extrusion stress and the shearing stress under the action of shearing stress to effectively convert the mechanical energy into the heat energy to be dissipated, thereby obviously improving the sound insulation effect of the sound insulation board, as shown in the right figure
