摘要
在对某小型军用汽油发电机组噪声的声压、声强测量和声激励的计算机数值模拟的基础上 ,进行了该机组机动密闭式隔声罩的设计研究 。
After the sound pressure and sound intensity measures of a miniature military gasoline generating set's noise and sound power's computer insulation, the authors accomplished the design and study of the sound insulation cover. The result of the experiment testified that the miniature military gasoline generating set's noise character signals are controlled efficiently.
