This paper describes techniques used to fabricate enclosures for reducing employee exposure to noise while attaining little or no operational hindrance. The noise enclosures discussed and shown include screw machines, scrap plastic regrinders and their related pneumatic conveying system, as well as high speed presses while having full view of their operation. Engineering design data and noise attenuation results are evaluated.
本文介绍了用于制造隔音罩的技术，这些隔音罩可减少员工接触噪音，同时几乎不会或完全不会造成操作障碍。所讨论和展示的隔音罩包括螺丝机、废塑料研磨机及其相关的气力输送系统，以及高速压力机，并且能对其操作进行全面观察。对工程设计数据和噪音衰减结果进行了评估。
