Firstly, it is necessary to start from the source and optimize processing equipment and technology. Noise mainly comes from the vibration and friction generated by the high-speed operation of equipment such as metal stamping, shearing, bending, and laser cutting. Therefore, using low-noise, high-precision advanced equipment is a key measure to reduce noise. For example, adding vibration reduction devices or using servo motor drives in shearing machines and stamping machines can effectively reduce vibration and noise during equipment operation. In addition, reasonably arranging processing parameters, such as controlling cutting speed, feed rate, and mold clearance, also helps to reduce the impact force of metal materials during processing, thereby achieving the purpose of noise reduction.

　　Secondly, improving the working environment is also an important means to reduce noise. It is possible to install soundproof walls, sound-absorbing panels, or use soundproof enclosures to isolate noise sources in the workshop. At the same time, optimizing the workshop layout by concentrating high-noise equipment in locations far from the office and living areas can reduce the impact on personnel and the surrounding environment. In addition,合理安排作业时间，避免在夜间进行高噪音操作，also helps to alleviate interference to nearby residents.



Thirdly, strengthening personal protection for employees is also indispensable. For noise that cannot be completely eliminated, enterprises should provide workers with high-quality earplugs or earmuffs and conduct regular hearing health checks to prevent hearing damage caused by long-term exposure to high-noise environments. At the same time, strengthening safety training and raising employees' awareness of occupational health and protection is also important.



Finally, enterprises should also pay attention to the application of environmental protection technology and the concept of green manufacturing. For example, using non-contact processing methods such as water jet cutting and laser cutting can not only improve processing accuracy but also significantly reduce noise levels; in terms of equipment maintenance, regular inspections and replacement of worn parts can help maintain good equipment operation and contribute to maintaining a low-noise working environment.

　　In summary, reducing noise in the process of sheet metal processing requires comprehensive strategies from multiple levels, including equipment, technology, environment, and personal protection. Only through the joint efforts of enterprises, employees, and society can the goals of green manufacturing, safe production, and sustainable development truly be achieved.
