What are the laws for preventing and controlling noise pollution

Noise is everywhere in our lives. It is a kind of sound that will hinder people's lives, and we must do a good job of preventing this kind of sound. There are many ways to prevent and control noise pollution. If you want to prevent and control noise pollution, you must prevent it from the root and control the noise at the source.

(1) Suppressing noise at the source

This is the most fundamental measure, including reducing the excitation force, reducing the response of each link of the system to the excitation force, changing the operating procedures or transforming the process.

(2) Control of noise propagation paths

This is a common technology in noise control, including sound insulation, the use of porous sound-absorbing materials and resonant sound-absorbing structures to absorb and muffle sound, damping and vibration reduction and other measures.

(3) Protection of the receiver

In some cases, the noise is particularly strong and the requirements cannot be met after taking the above measures, or when noise is unavoidable during operation, measures need to be taken from the perspective of receiver protection. For people, they can wear earplugs, earmuffs, active noise-cancelling helmets, etc. Precision instruments and equipment can be placed in a soundproof room or a vibration isolation table.

(4) Prevention at the source and reduction of transmission process

Although noise control technology is now mature, due to the large scale of modern industry and transportation, there are many enterprises and places that need to adopt noise control measures. Therefore, in preventing noise problems, a comprehensive balance must be made from the aspects of technology, economy and effect. Of course, specific issues should be analyzed specifically. Outside the control room, design room, workshop or places where employees work for a long time, the noise intensity should be low; in warehouses, workshops with few people or open places, a slightly higher noise level is acceptable. In short, there should be certain differences in the treatment of noises at different times, places, natures and durations.
