摘要
分析了某生产线车间噪声分布特性及操作室和配电室之间通风的要求,设计了合理的送、排风系统,并对操作室进行隔声降噪综合治理,使操作室内距观察窗0.5 m处A声级噪声由84 dB(A)降至68.2 dB(A)。
After analysis of noise distribution characteristics of the production line and ventilation requirements between workshop and power distribution room, this palSer provides an improved design of ventilation system, in which some noise control measures are taken to lower the noise in A sound level inside the room at a point 0. 5m away from the observing window from 84dB （A） to 68.2dB （A）.
