APPLICATION STUDY OF NOISE CONTROL TECHNOLOGY IN MECHANICAL INDUSTRY
ABSTRACT
This paper summarizes the relevant overview of mechanical noise in the machinery industry, the control technology and its application, the challenges faced and the coping strategies. First, mechanical noise is defined and classified in detail as aerodynamic, mechanical and electromagnetic noise, while exploring the main sources of noise in the mechanical industry. Subsequently, the paper deeply analyzes the application and problems of noise control technology in mechanical industry, such as the limitations of the technology itself, especially the difficulty of low frequency noise control and active noise control technology; the variety of noise sources, which increases the difficulty of control; the high equipment cost, limits the wide application of noise control technology; and the harsh working environment, put forward higher requirements for the performance of noise control equipment. In order to meet these challenges, this paper puts forward corresponding strategies, including comprehensive application of various technical means to improve the effect of noise control, developing new materials and new technologies to improve the accuracy and stability of active noise control technology; meanwhile, it is suggested to establish a perfect noise monitoring network to provide the basis for scientific formulation of control measures; reduce the burden of enterprises through policy support and financial subsidies, and promote the popularization of noise control technology; and improve the working environment to provide good conditions for the normal operation of noise control equipment. The implementation of these strategies will help to promote the sustainable development of the machinery industry, reduce the noise pollution, and improve the quality of the production environment.
