Mechanical equipment will produce certain noise problems during operation, including the noise generated by the operation of internal parts of the equipment and pneumatic noise. In order to reduce mechanical noise pollution, protect the environment around the machinery and personnel safety, it is necessary to control the noise of the machinery operation within the standard value. Noise pollution is one of the three major pollutants in the world, which also affects peoples lives and even reduces peoples physical and mental health. In order to reduce noise pollution and continuously improve the development level of mechanical equipment, it is necessary to actively integrate vibration and noise reduction technology into mechanical design. Therefore, in the design stage of mechanical equipment, vibration and noise reduction measures should be taken to control noise source and noise propagation path, enhance the noise reduction, sound insulation and sound absorption functions of mechanical design, prevent mechanical vibration and pneumatic noise in advance, form good vibration and noise control in the operation stage of mechanical equipment, and strengthen the vibration and noise reduction effect of mechanical design. Ensure the safety and reliability of mechanical equipment after it is put into use.
