Hydropower forging is an important part in hydraulic engineering, its quality and performance directly affect the safety and operation of hydraulic engineering. In the production process, hydropower forgings need to go through multiple processes and complex process treatment, involving equipment, personnel, materials and energy and other aspects. In order to improve production efficiency and quality, and reduce the impact of noise and vibration on the production environment, employee health and product quality, it is necessary to control noise and vibration.

The cause of noise and the way of transmission
In the production process of hydropower forgings, the noise mainly comes from the operation of mechanical equipment, the impact and friction of materials. These noises are transmitted through the air and affect the production environment and the health of employees.
The basic principle and method of noise control
The basic principle of noise control is to take corresponding measures to reduce the generation, propagation and reception of noise from three aspects: sound source, propagation path and receiver. Common noise control methods include:
(1) Sound source control: adopt low noise equipment, improve mechanical structure, optimize the process flow and other measures to reduce the noise level of the sound source.
(2) Propagation path control: adopt measures such as sound absorption, sound insulation and noise reduction to block or weaken the propagation path of noise.
(3) Receiver protection: Adopt personal protective equipment, reasonable arrangement of working hours and other measures to protect the health of employees.
