| Abstract: | Polyurethane foam(PU)was prepared by one-step method using polyether polyol and isocyanate as raw materials.PU and micro-perforated plate(MPP)were combined to prepare a novel layered sound absorbing structure.The effects of porosity,cavity depth,material and MPP thickness on the sound absorption performance were studied.The results show that the designed layered sound absorbing structure has good sound absorption performance,and the designed sound absorbing structure has the best sound absorption performance when the cavity thickness is 20mm. |
