| 摘 要： | 抛丸清砂机在利用压缩空气做功时发出强烈的喷注噪声，同时它在工作中又会产生较强的撞击噪声。本文论述了喷注噪声和撞击噪声的不同类型、产生机理。经消声、隔声等声学措施后，进风口和工人操作点的噪声强度分别降低３３和１０ｄＢ（Ａ）以上，达到了预期的效果。

| Abstract: | Shot-blast cleaning machine generates strong blowing noise with compressed aerodynamics and strong ramming noise when machine is being operated.The paper expounded different types and generating machauism of the blowing and ramming noise.With the treatment of acoustic measures of noise elimination and sound insulation,the reducing of noise level at enter port and operating point exceeds 33dB(A)and 10 dB(A) respectively,this comes to the desired results. |
