What are the main protection measures against noise

The main protection measures against noise are as follows:

1. To reduce the noise of the sound source, the industry and transportation industry can choose low-noise production equipment and improve the production process, or change the movement mode of the noise source (such as damping, vibration isolation and other measures to reduce the vibration of the solid sound emitter).

2. Reduce noise in the sound transmission pathway, control the propagation of noise, and change the noise transmission path that has been emitted by the sound source, such as the use of sound absorption, sound insulation, sound barrier, vibration isolation and other measures, as well as reasonable planning of urban and building layout.

3. When measures cannot be taken in the sound source and transmission path, or the acoustic measures taken still cannot achieve the expected effect, it is necessary to take protective measures for the sound recipient or the sound receptor organ, such as workers who are exposed to long-term occupational noise can wear earplugs, earmuffs or helmets and other ear protectors.

1. The energy of sound propagation is attenuated with the increase of distance, so keeping the noise source away from the place that needs to be quiet can achieve the purpose of noise reduction.

2. The radiation of sound is generally directional, and the received sound intensity is different when it is located at the same distance from the sound source but in a different direction. However, most sound sources have poor directivity when radiating noise at low frequencies; As the frequency increases, the directivity increases. Therefore, controlling the propagation direction of noise, including changing the emission direction of the sound source, is an effective measure to reduce noise, especially high-frequency noise.

3. Establish sound barriers, or use natural barriers (soil slopes, hills), and other sound insulation materials and sound insulation structures to block the spread of noise.

4. Apply sound-absorbing materials and sound-absorbing structures to convert the noise and sound energy in the propagation into thermal energy.

5. In urban construction, adopt reasonable urban noise prevention planning. In addition, noise generated by solid vibrations is isolated to reduce noise propagation.

1. Prevention and management: In order to protect people's hearing and physical health, the allowable value of noise is 75 90 decibels; To ensure conversation and communication, the allowable value of ambient noise is 25 50 decibels; For sleep time is recommended at 35 to 50 decibels.

2. Noise control methods: to reduce the noise of the sound source, the industry and transportation industry can choose low-noise production equipment and improve the production process, or change the movement mode of the noise source; Reduce noise in the sound transmission pathway, control the transmission of noise, and change the noise transmission path that has been emitted by the sound source; Noise protection of the person receiving the sound or the organ of the sound recipient, such as workers who have been exposed to occupational noise for a long time can wear sound-isolating earplugs, etc.

3. Prevention and control methods: create soundproof forests; moving companies with high levels of noise pollution out of urban areas; Prevention at the source, reduction of the transmission process.

1. Noise pollution control technology, using porous sound-absorbing materials and resonant sound-absorbing structures to reduce noise. Use sound insulation structure to shield sound energy and reduce sound radiation, thereby reducing noise hazards.

2. At the first level, integrate resources, increase publicity and management, and whether the prevention and control of environmental noise pollution can be effective, the key lies in the degree of attention. ** and relevant departments should strengthen the leadership of environmental noise pollution prevention and control, formulate and implement mandatory noise control and management regulations, to ensure a quiet environment in the city. Traffic noise sources have high noise levels and high mobility, and a wide range of pollution.

Environmental noise pollution refers to the phenomenon that the environmental noise generated exceeds the environmental noise emission standards stipulated by the state and interferes with the normal life, work and study of others. Environmental noise pollution is a kind of energy pollution, which, like other industrial pollution, is a public nuisance that endangers the human environment.

3. Control of traffic noise. Public security, transportation, agricultural machinery, construction and other departments should be coordinated to make them perform their duties and work together; Speed up the construction of urban roads and improve road conditions.

Legal Analysis: Noise risk prevention and control measures include environmental remediation measures, personal protection and health monitoring. It is an effective measure to reduce urban environmental noise by doing a good job in the scientific planning of various functional areas in the city and rationally carrying out the urban noise prevention layout.

Legal basis: "Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution" Article 5 When formulating urban and rural construction plans, local people at all levels shall fully consider the impact of noise generated by construction projects and regional development and transformation on the surrounding living environment, make overall planning, reasonably arrange functional areas and construction layouts, and prevent or reduce environmental noise pollution.

Legal Analysis: The most fundamental measure to prevent noise hazards is to control and eliminate the source of noise.

Legal basis: "Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution" Article 2 The term "environmental noise" as used in this Law refers to the sound generated in industrial production, building construction, transportation and social life that interferes with the surrounding living environment. "Environmental noise pollution" as used in this Law refers to the phenomenon that the environmental noise generated exceeds the environmental noise emission standards prescribed by the state and interferes with the normal life, work and study of others.

The most fundamental measure to prevent noise hazards is to reduce the noise level of the noise source through technical means, and at the same time take personal protective measures, such as wearing earplugs.

Noise is one of the inevitable sources of environmental pollution in modern society, and long-term exposure to high-intensity noise can easily lead to a variety of occupational diseases, physical and mental injuries and other hazards. In order to reduce noise hazards and prevent noise from affecting people's health, corresponding protective measures should be taken. First of all, the most fundamental measure to prevent noise hazards is to use technical means to reduce the noise level of the noise source.

This requires the establishment of strict noise control standards and strengthened supervision, and the implementation of noise control measures for industries and enterprises with noise pollution, such as improving production processes, adjusting production processes, and updating equipment. Secondly, personal protection is also very important, and you can reduce the harm of noise to the human body by wearing earplugs, earmuffs or customized personal protective earplugs. For professionals who need to work in a high-noise environment for a long time, a shift system should be implemented to avoid continuous exposure to high-intensity noise for a long time.

It should be noted that to prevent noise hazards, publicity and education should also be strengthened, people's awareness of noise hazards should be improved, and scientific preventive measures should be popularized.

What are the dangers of noise to human health? Long-term exposure to noise environment can easily induce a variety of occupational diseases, such as noise deafness, cardiovascular diseases, nervous system diseases, mental disorders, etc., and will also have an impact on people's mental conditions, resulting in distraction, memory loss, emotional irritability and other adverse consequences of empty crying.

Preventing noise hazards requires technical means to reduce the noise level of the noise source, while taking personal protective measures such as wearing earplugs. The key to preventing noise pollution is to establish strict noise control standards, strengthen supervision, and raise people's awareness of noise hazards.
