摘　　要：本文主要研发了一种新型的窄缝式结构的吸隔音板，并对影响其降噪效果的参数进行了分析和优化。实验结果表明，在固定频率下，窄缝缝隙的大小，对降噪效果影响较大；在窄缝缝隙大小固定时，镁合金层板表面的阻尼状况，对其降噪效果影响较大。This paper studies a novel narrow composite structure plate about sound--absorbing and insulation materials. , and analyze and optimize the parameters affecting the effects of the noise reduction. Experimental results show that when the frequency is fixed, the size of the gap has a great influence on the noise reduction effect. When the size of the gap is fixed, the damping condition of the magnesium alloy surface has a larger effect on noise reduction effect.
