近年来为进行噪声测试和分析,兴建精密消声室的单位日益增多。为减少周围环境对消声室的干扰和影响,多数均是与其它建筑物脱开而单独建造,这样,成本高、建设周期长、工艺流程不尽合理。能否利用原有建筑,采取适当措施,既满足测试精度要求,又使工艺流程相对合理,投资又较少呢?我们在为航空工业部三三三七厂和苏州电机厂消声室的设计过程中,进行了这一尝试,取得了满意的效果。现以三三三七厂的
In recent years for noise testing and analysis, building a sophisticated anechoic chamber unit is increasing. In order to reduce the interference and impact of the surrounding environment on the anechoic chamber, most of them are constructed separately from other buildings so that the cost is high, the construction period is long, and the technological process is not reasonable. Can use the original building, take appropriate measures to meet the testing accuracy requirements, but also make the process is relatively reasonable, less investment? We are in Aerospace Industry 3337 Factory and Suzhou Electrical Factory anechoic chamber design In the process, this attempt was made and satisfactory results were obtained. Now three thirty-three factory
