How to Address Noise Issues in a 1000-ton Hydraulic Press?

I. Reduce the Noise from Noise Sources

1. 1.Enhance the machining and assembly precision of the 1000-ton hydraulic press to minimize noise generated from mechanical vibrations and friction.
2. 2.Revise production processes and opt for hydraulic presses with lower noise levels.
3. 3.Reduce pressure differentials and flow velocities in high-pressure, high-speed airflows, or alter the shape of airflow nozzles.

II. Control Propagation Along Transmission Paths

1. 1.Design the overall layout reasonably. When planning the layout of factories or mines, position major noise sources, such as workshops or devices, away from areas requiring a quiet environment like laboratories and offices. Concentrate high-noise equipment to facilitate control.
2. 2.Use barriers to block noise propagation or leverage natural features such as hills, slopes, trees, bushes, or tall structures that tolerate noise.
3. 3.Utilize the directional characteristics of sound sources to control noise. For example, direct outlets of high-pressure boiler steam, blast furnace venting, or oxygen production machine exhaust towards open fields or the sky to minimize environmental impact.

III. Protection for Receivers

1. 1.Provide personal protection for workers, such as wearing earplugs, earmuffs, helmets, and other noise-reducing equipment.
2. 2.Implement worker rotation to reduce the time workers spend in high-noise environments.
