Noise refers to the sound that people don't need. No matter what sound, as long as it is annoying and interferes with people's lives, it is called noise. The roar of machinery in the factory, the horn of cars on the road and the noise of people are all headaches. Sometimes strong rhythm rock music, disco, etc. It will also become noise and affect people's life and health.

Strong noise can cause hearing organ damage. If people work in a factory with roaring machines for a long time, their hearing is often not as good as that of ordinary people. Noise can also seriously interfere with people's central nervous system, making people neurasthenia, indigestion, and even nausea and headache. Noise also has a great influence on people's normal life and work. Can make people insomnia, loss of appetite, trouble and other unpleasant emotions. Scientists have also found that long-term noise stimulation will also weaken the function of human immune system and increase the incidence of malignant tumors.

Complaints about noise pollution are increasing.

It is reported that with the development of economy and the improvement of people's environmental awareness, the number of environmental complaints is also increasing. Last year, the whole region accepted 84 1 piece of environmental complaints, which was 3.6 times of the total number of complaints last year. Noise pollution accounts for 34% of the total complaints.

Noise pollution means that the environmental noise emitted exceeds the national standard and hinders people's work, life and other normal activities. According to reports, noise exceeding 50 decibels will affect sleep and rest; More than 70 decibels will interfere with the conversation, causing upset, inattention and reduced work efficiency; Working or living in a noise environment above 90 decibels for a long time will seriously affect hearing, cause hearing damage, and gradually develop into noise deafness. In addition, noise can also cause harm to non-hearing organs or cause other diseases.

Noise pollution mostly occurs in the middle of the night.

The noise mainly occurs at night. Take Huicheng Red Lip Bar renovated some time ago as an example. The approval of the environmental protection bureau clearly stipulates that only pubs are allowed to operate. However, without going through the environmental protection approval procedures again, the bar added karaoke items and played disco music, which led to excessive noise at the border and constant complaints from the masses.

Because the bar was closed during the day and it was impossible to obtain evidence, the staff of the District Environmental Monitoring Brigade had to lie in ambush until late at night for seven consecutive days and found that it was open until 2 am almost every day. The continuous monitoring by the district environmental monitoring station on March 3rd and 4th found that the environmental noise of the bar was lower than the specified standard of 50 dB when it was not open, but it was as high as 59.9 dB at night 1 1 when it was open. Based on this, the district environmental protection bureau confirmed that the noise of the red lip bar exceeded the standard and dealt with it according to law.

The EPA pointed out that overtime work is also the main cause of noise pollution. For example, in recent years, Huicheng District has opened many Internet cafes, most of which are under residential buildings or residential quarters. The noise of customers and the roar of motorcycle motors have seriously affected residents. The Regulations on the Administration of Internet Service Sites promulgated by the State Council in 2002 clearly stipulates that the business hours of Internet cafes are from 8 am to 2 pm 12 pm. On March 2, this year, the District Environmental Protection Bureau and the District Cultural Bureau formed a joint team to conduct an investigation, only to find that all the Internet cafes inspected were open in the afternoon of 12, or even all night.

In addition, there are restaurants, entertainment and hardware stores, processing plants and so on. , distributed under urban streets and commercial and residential buildings, environmental pollution and nuisance problems are also prominent.
