With the acceleration of industrialization, the problem of industrial noise has become increasingly prominent, and it has become one of the important factors affecting people's life and health. In order to solve this problem, industrial enterprises need to take effective noise control measures to reduce the impact of noise on the surrounding environment and people. This article will focus on the methods of controlling industrial noise and the noise control measures of industrial enterprises, so as to provide reference and reference for relevant enterprises and people.
1. Methods for controlling industrial noise.
1.Sound absorption and noise reduction.
Sound absorption and noise reduction is a method to achieve the purpose of noise reduction by setting sound-absorbing materials in the noise propagation path to convert sound energy into heat energy. This method is mainly suitable for reducing high-frequency noise, such as noise generated by mechanical vibration, hydrodynamics, etc. Commonly used sound-absorbing materials are glass fiber, mineral wool, carbon fiber, etc., which are porous and fibrous, and can effectively absorb and consume sound energy.
2.Noise reduction and noise reduction.
Noise reduction is a method to eliminate or reduce the propagation of noise by setting a muffler in a pipe or equipment, so as to achieve the purpose of noise reduction. This method is mainly suitable for reducing low- and medium-frequency noise, such as noise generated by aerodynamic equipment, ventilation and air conditioning systems, etc. Commonly used mufflers include resistive mufflers, resistant mufflers, impedance composite mufflers, etc., which can effectively eliminate or reduce the propagation of noise.
3.Sound insulation and noise reduction.
Sound insulation and noise reduction is a method to achieve noise reduction by isolating the equipment that produces noise and the surrounding environment to prevent the spread and spread of noise. This method is mainly suitable for reducing low- and medium-frequency noise, such as noise generated by machining, forging, etc. Commonly used sound insulation structures include sound insulation covers, sound insulation walls, sound insulation doors and windows, etc., which can effectively isolate and block the transmission of noise.
2. Noise control measures for industrial enterprises.
1.Formulate a reasonable noise control plan.
Industrial enterprises should formulate a scientific, reasonable and feasible noise control plan according to their own production process and equipment characteristics, combined with the requirements of the surrounding environment and relevant laws and regulations. At the same time, it is necessary to give full consideration to the economy, practicability and operability of the governance plan to ensure that the governance plan can be effectively implemented.
2.Strengthen equipment maintenance and overhaul.
Industrial enterprises should strengthen the maintenance and overhaul of noise-generating equipment, regularly inspect, clean and replace wearing parts of the equipment, and ensure the normal operation and service life of the equipment. At the same time, it is necessary to update equipment and technology in a timely manner according to the actual situation, improve the efficiency and reliability of equipment, and reduce the generation and propagation of noise.
3.Reasonable layout of production process and equipment layout.
When designing and constructing production workshops, industrial enterprises should fully consider the layout of equipment and the arrangement of technological processes, and keep the equipment and processes that produce noise away from densely populated areas as much as possible to reduce the impact on personnel. At the same time, it is necessary to reasonably design the ventilation and heat dissipation in the workshop to reduce unnecessary noise.
4.Strengthen protective measures for employees.
Industrial enterprises should strengthen protective measures for employees, provide staff with earplugs, earmuffs and other protective equipment, conduct regular hearing tests and health examinations, and discover and deal with hearing problems in a timely manner. At the same time, it is necessary to strengthen the training and education of employees to improve their safety awareness and self-protection ability.
5.Establish a sound noise monitoring system.
Industrial enterprises should establish a sound noise monitoring system to monitor and analyze the noise inside and outside the workshop, at the boundary of the plant and other areas in real time, and find and solve problems in a timely manner. At the same time, through the analysis and comparison of monitoring data, it is necessary to continuously optimize the governance plan and technical measures to improve the governance effect and economic benefits.
To sum up, there are several ways to control industrial noise, such as sound absorption and noise reduction, noise reduction and sound insulation and noise reduction. The noise control measures of industrial enterprises need to start from the formulation of reasonable treatment plans, strengthening equipment maintenance and overhaul, rationally laying out production processes and equipment layouts, strengthening employee protection measures, and establishing a sound noise monitoring system. By taking effective measures and methods, we can effectively reduce the impact of industrial noise on the surrounding environment and personnel, and protect people's health and quality of life.
