Noise and Vibration Monitoring

The harm of noise and vibration has a long history, and only in modern times has it attracted widespread attention. Looking back on history, there were reports of noise deafness of forgers in the 18th century, but it was not until after the second world war that the number of deafness caused by gun noise increased sharply that the noise began to attract the attention of the medical community. Researchers have carried out a series of research work on noise induced deafness, and many countries have successively published research reports on deafness caused by industrial noise.

With the development of modern industry and transportation, noise pollution has become more and more serious, and has become a world public hazard. It affects people's life, sleep, study, work and physical and mental health. Over the years, China has taken many noise control and management measures, and the acoustic environment has been improved, but the speed of treatment lags behind the speed of pollution. With the improvement of people's material and cultural living standards and the strengthening of environmental protection awareness, noise pollution complaints are still high. According to the information provided in the 2017 report of the Ministry of environmental protection on the prevention and control of environmental noise pollution in China, environmental protection departments at all levels across the country received 1.19 million environmental complaints in 2016, of which 522000 were noise complaints, accounting for 43.9% of the complaints (the completion rate was 99.1%), of which industrial noise accounted for 10.3%, construction noise accounted for 50.1% (night construction noise complaints accounted for 90.5% of such complaints), Social life noise accounts for 36.6%, and transportation noise accounts for 3%. From the 1960s to 1970s, aviation noise has reached an intolerable level.

China's noise law will be formally implemented in 2022, and the supervision and management will be further strengthened. The whole society will pay more attention to the problem of noise and vibration, and China's noise and vibration control industry will usher in a new period of development.

With the implementation of the noise law and the requirements of the opinions for the implementation of noise pollution prevention and control actions, the noise pollution prevention and control action plan will be issued and implemented. The demand for noise monitoring and control equipment will increase, and the noise and vibration control industry will usher in a new period of development opportunities. NOA, as a third-party comprehensive testing organization, can issue objective and true noise evaluation reports.

Q&A

What are the hazards of vibration?

Various vibrations produce noise, affect the surrounding environment, endanger human health, damage buildings, reduce the processing accuracy of equipment, and affect the use effect of instruments, especially high-grade valuable instruments. When vibration occurs, the machine itself is also damaged by vibration, shortening its service life.

What are the hazards of environmental noise?

(1) Interfere with rest and sleep, and affect work. The study found that only 40db~50db light noise will affect people's sleep. 40dB sudden noise can wake up 10% of people, and when the sudden noise reaches 60dB, 70% of people will be awakened. Long term interference of environmental noise with sleep will cause insomnia, fatigue, memory loss, and even neurasthenia syndrome, which can seriously affect normal work.

(2) Deafness. The impact of noise on the auditory system is related to the intensity of noise and the length of noise exposure time. Noise intensity and exposure time together constitute the noise exposure dose, which determines the impact of noise on the auditory system. Generally, noise below 85dB will not harm hearing, while noise above 85dB may damage hearing. Research shows that the incidence rate of deafness is significantly increased for people who work in a noise environment of more than 90dB for a long time.

(3) Others. Damage to the cardiovascular system, long-term exposure to noise will increase the secretion of adrenaline in the body, resulting in an increase in blood pressure. For people living in an average 70dB noise environment for a long time, the incidence rate of myocardial infarction will increase by about 30%, and nighttime noise will make the incidence rate higher. The working environment with strong noise can make people dizzy, headache, insomnia, dreaminess, general fatigue, memory loss, fear, irritability, inferiority complex and even insanity. Women who are disturbed by noise will also have sexual dysfunction, menstrual disorders, increased abortion rate and so on.

What is vibration?

Vibration is an oscillation phenomenon of the amount of motion (displacement, velocity and acceleration) in a mechanical system.

What are the characteristics of noise?

Noise pollution, air pollution, water pollution and solid waste pollution are called the four major environmental hazards. Environmental pollution caused by noise is different from air pollution, water pollution and solid waste pollution. Noise is a kind of physical pollution, which generally only produces local effects and will not cause regional or global pollution; Noise always exists in the environment and is harmless to people. Only when the total amount of the environment is too high or too low, it will cause pollution or abnormality; In addition, unlike other pollution, noise pollution will have pollution residues. Once the noise source stops sounding, the noise source pollution will disappear. According to the law of the people's Republic of China on the prevention and control of environmental noise pollution, environmental noise is mainly divided into industrial noise, construction noise, transportation noise and social life noise according to the source.
