摘　　要：利用CUSI—II型声强测量分析系统及HS56 6 0A型精密声级计 ,分析了DF30 0 0型汽油发电机组主要噪声源的分布情况 ,提出了用隔声罩对DF30 0 0型汽油机组进行降噪隐身。同时重点考虑了隔声罩的通风散热问题 ,设计出了可拆卸的百叶窗式隔声罩。试验证明 ,其具有良好的通风及隔声性能。The design rely on using CUSI-II sound intensity measuring and analyzing system and HS5660A accurate sound spectrograph, analyzed the scatter circumstances of DF3000 gasoline generating set main noise source. Put forward using soundproof hood to increase its noise realize making itself invisible considering ventilate raliate,plan to endismantle soundproof hood with scatter.Experiment make clear that the soundproof hood have very good performance of venbilating and noise elimination.
