Does the noise in the middle of the night make it difficult for you to sleep, does the horn of the car make you upset, does the noise of the neighbors' crackling decoration, and the noise of the late-night square dance? It makes you unbearable, these sounds can be heard everywhere in our daily life, interfering with our normal rest, study and work
.
And car horns, factory machines, construction machinery and even household appliances are the main culprits of noise, and the once simple "I want to be quiet" has become a luxury

And car horns, factory machines, construction machinery and even household appliances are the main culprits of noise, and the once simple "I want to be quiet" has become a luxury
.
The continuous development of modern society not only brings prosperity and progress to human beings, but also brings noise to human beings
.
With the rapid development of industrialization and urbanization, noise pollution has increasingly become one of the important environmental issues of public concern
.
Noise pollution mainly includes industrial noise pollution, construction noise pollution, transportation noise pollution and social life noise pollution
.
According to data from the Ministry of Ecology and Environment, in 2020, the national ecological environment petition report management platform received more than 441,000 reports from the public, of which noise disturbance accounted for 41.
2%, ranking second in various environmental pollution factors
.
Among all noise pollutions, social life noise complaints are the most reported, which shows that noise pollution has brought great troubles to people's lives

Policies and regulations continue to improve Noise prevention and control work continues
Policies and regulations continue to improve Noise prevention and control work continues The three-year action plan for winning the battle to defend the blue sky in 2020 was implemented, the "14th Five-Year Plan" and the 2035 long-term goals and objectives were also put forward one after another, and the content of noise pollution control was also included in the national economic and social development plan for the first time
.
Therefore, in terms of noise pollution prevention and control, departments at all levels continue to improve laws and regulations, carry out special rectification actions, promote environmental noise monitoring, increase scientific research and industrial development of related equipment, and promote the smooth development of environmental noise pollution prevention and control
.
What is more noteworthy is that in order to alleviate the troubles caused by noise to people, prevent noise pollution, and protect public health, on December 24, 2021, the "Noise Pollution Prevention and Control Law of the People's Republic of China" passed a resolution and is scheduled for June 2022.
Effective from the 5th of the month
.
The promulgation of this law has played an important role in protecting and improving the living environment of the public, maintaining social harmony, and promoting the construction of ecological civilization

Recently, the Ministry of Ecology and Environment released the "Technical Guidelines for Environmental Impact Assessment Acoustic Environment" (HJ 2.
4-2021), which will be implemented on July 1
.
This "Guide" is a revision and improvement on the basis of the current "Environmental Impact Assessment Technical Guidelines on Acoustic Environment" (HJ2.
4-2009), and it is also a full implementation of the "Noise Pollution Prevention and Control Law of the People's Republic of China"
.
This revision is in line with the new situation facing the current ecological and environmental protection work, and adheres to the principle of problem orientation and overall consideration.
Five aspects of prevention and control countermeasures and measures, basic data requirements and specifications have been improved, and 19 normative forms have been summarized and condensed in the appendix to provide professional and reliable data support for EIA documents in key industries
.
With the subsequent update and improvement of these Guidelines, these Guidelines will play an important role in the sound environmental impact assessment work to ensure the health and safety of the people in terms of the sound environment

According to the data, the sound of 70 decibels is the maximum suitable for the human auditory system.
If it exceeds this decibel, it will make people feel noisy.
If they are in a noisy environment for a long time, the nerve cells of people will be damaged and even enough to make the hearing inside the ear.
Hair cell death or damage, resulting in hearing loss, is extremely harmful to the human body
.
According to Chinese standards, the noise level of residential areas during the day shall not be higher than 55 decibels, and the noise level at night shall not be higher than 45 decibels
.
Even around the main road, the noise level during the day should not be higher than 70 decibels
.
Therefore, it is very important to carry out noise detection work to prevent excessive sound decibel value from causing damage to the human body

When monitoring noise, the intensity and characteristics of noise are the main monitoring indicators.
The main measuring instruments are: sound level meter, frequency analyzer, real-time analyzer, sound intensity analyzer, noise level analyzer, noise dosimeter, automatic recorder , tape recorders, etc.
The application of these instruments can display the decibels reached by the noise, so that we can take relevant measures to control and reduce the noise and reduce the harm to ourselves
.
In order to improve the level of noise monitoring, environmental protection departments at all levels and related enterprises in China are strengthening the research and development of noise monitoring instruments and equipment.
The data shows that the total output value of the national noise and vibration pollution prevention and control industry in 2019 is about 12.
8 billion yuan, and the market dividend is large
.
It is believed that with the continuous development of science and technology and the promotion of relevant policies, the noise monitoring instrument market will usher in greater market demand

Due to people's attention to noise pollution, in addition to driving the development of the noise detection instrument industry, the sound insulation material industry is currently booming in the market
.
Sound-absorbing and sound-absorbing materials refer to materials that can block sound transmission or reduce sound reflection to reduce sound energy.
They are widely used in home improvement, factories, offices, public buildings, transportation and other fields
.
Taking home decoration as an example, we usually choose sound insulation materials such as sound insulation walls, sound insulation windows, and sound insulation doors when decorating.
These building sound insulation materials have high technical content in green buildings, which can best reflect the comfort of the building and are also related to quality of life of people
.
In the current market, whether online or offline, the public can easily buy sound insulation materials to meet the needs of noise prevention and control
.
Of course, in addition to home decoration, noise barriers on highways, sound insulation and noise reduction systems on cars, and sound insulation blankets in public places are all involved in the sound insulation material industry.
The development of modern technology has prompted more and more types of sound insulation materials to face the market.
, bringing more choices to consumers, and the attention to noise pollution has also made the future of the sound insulation material industry promising

In the past, noise pollution was often not as important as water pollution and air pollution.
People's vision has become an important area of environmental pollution prevention and control
.
With the promulgation and implementation of the Law of the People's Republic of China on the Prevention and Control of Noise Pollution, noise pollution will be further solved, and people will have a "quiet" world
