摘　　要：阐述了屏蔽隔声技术理论,并应用该理论对某125mL摩托车进行试验研究。通过在摩托车进气口加装屏蔽隔板和吸声材料,进气口辐射噪声分别下降了0.7dB和1.2dB,这与理论预测隔声量相吻合。试验结果表明屏蔽隔声能有效地抑制摩托车噪声,是控制噪声的有效途径之一。This paper expounds shield and sound installing panel of sound isolation and plastering isolation theory, and applies material of sound absorption it on 125 mL motorcycle. on motorcycle air intake, noise radiated level decreased by 0.7dB and 1.2dB, these tally with theoretic sound transmission loss. result indicates that shield and sound isolation technology can restrain motorcycle noise availably, shield sound isolation technology is an effective method of controlling noise.

关 键 词：摩托车 噪声 屏蔽隔声 隔声量
