本讲座的目的在于使读者对噪声的基本性质、测量方法、噪声的危害及允许标准,有一基本了解。文中结合工程实例从理论与实践上,对铸造车间的噪声特性、控制方法,作了分析与介绍。从而,使读者对铸造车间噪声的现状及控制方法,有所认识和掌握。以给广大铸造工作者在进行铸造车间设计及技术改造、实施改善作业环境、降低噪声危害等,提供一可以借鉴的技术参考资料. The purpose of this lecture is to give the reader a basic understanding of the basic nature of noise, the measurement methods, the hazards of noise and the permissible standards. Based on the engineering examples, the paper analyzes and introduces the noise characteristics and control methods of casting shop from the theory and practice. Thus, the reader of the casting workshop noise status and control methods, knowledge and grasp. In order to give the majority of foundry workers casting workshop design and technical transformation, the implementation of improved operating environment, reduce noise hazards, etc., to provide a reference for technical reference.
