| 英文摘要 |
The decoration industry works in residential areas during construction, and the noise generated during construction often arouses public disgust. According to occupational safety and health regulations, transmission motors, ball mills, and air drills used in the workplace are all machines that produce strong noise. If the noise exceeds 85 decibels, they should be isolated, sealed, and provided with sound-absorbing materials to reduce the noise. This project adheres to the principle of maintaining the portability of the machine. If the noise generated by the use of the sawing machine can be reduced, it will be helpful to the health and safety of workers and reduce neighborhood resentment. |
