The noise decibels of square dancing stipulate how many decibels the volume of square dancing is con

Square dancing noise decibels are set below 60 decibels. The specific noise decibel regulations are as follows:

Class (refers to residential areas that need to be quiet, such as recuperation areas, high-end villa areas, high-end hotel areas, etc.) have a limit of 50 decibels during the day and 40 decibels at night;

Class (Applicable to areas with residential, cultural and educational institutions.) The rural living environment can refer to the implementation of such standards) the daytime limit is 55 decibels, and the nighttime limit is 45 decibels;

Class (applicable to residential, commercial, and industrial mixed areas) has a daytime limit of 60 dB and a nighttime limit of 50 dB;

Class (applicable to industrial zones) limits 65 dB during the day and 55 dB at night;

Class (applicable to the areas on both sides of the road traffic arteries in the city, and the areas on both sides of the inland waterway through the urban area.) The background noise (i.e., the noise level when not passing through the train) in the area on both sides of the main and secondary railway lines passing through the urban area is also subject to the same standard) with a limit of 70 decibels during the day and 55 decibels at night.

Noise is usually harmful to the human body in the following ways:

1. Seriously affect the function of the central nervous system, resulting in nervous system weakness and dysfunction of the nervous system, such as long-term noise will lead to insomnia, dreaminess, poor rest and sleep conditions, or poor quality of rest and sleep, shortening of deep sleep phase, prolonged light sleep phase, or neuropathic headache, migraine, insomnia, dreaminess and other clinical symptoms and manifestations;

2. Symptoms of cardiac insufficiency, which will lead to coronary ischemia and transient vasospasm under the harm of noise for a long time, resulting in chest tightness, shortness of breath, palpitations, precordial discomfort and other conditions;

3. Noise can also cause irreversible damage to the ear canal and auditory system, such as leading to neural tinnitus or even nervous deafness.

Article 45 of the Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution prohibits any unit or individual from using loudspeakers in areas where noise-sensitive buildings are concentrated in urban areas. If the use of audio equipment may produce excessive noise that may interfere with the surrounding living environment, the regulations of the local public security organs must be complied with.

Square dance noise is a contradiction that needs to be solved urgently in people's livelihood, but it is usually difficult to obtain evidence and define responsibility in square dance noise control, square dance noise pollution is fleeting, it is difficult to obtain direct evidence, and there are difficulties in monitoring and collecting evidence, defining responsibility, and implementing supervision.

At present, the main governance methods are as follows:

1.The square is managed by the relevant local supervision units, and is open at a fixed time every day, and the volume of the speakers is strictly controlled, and verbal warnings or fines will be imposed for violations;

2.Install a large decibel monitoring screen, and when the decibel exceeds the standard, the supervisor will conduct on-site persuasion or punishment;

3.Those participating in the square dance wear headphones.

However, judging from the actual implementation situation, it is difficult to determine the responsibility for control, and the above measures are still a symptom rather than a root cause.

Silent dance hall solves the square dance problem.

At present, the main core problem of square dance noise is noise overflow, grasping the core contradiction and solving the problem.

Based on the application of directional sound technology, the silent dance scene allows the square dance music to sound in the designated area, and the sound decibel is greatly attenuated except for the designated area, which can solve the problem of square dance noise disturbing the people from the source.

Schematic diagram of the sound field of directional sound technology.

The principle of silent dance hall technology.

What is the principle of such a magical new acoustic black technology:

To put it simply, directional sound technology is to condense sound waves into a sound column with an extremely narrow beam width through parametric array acoustic technology, which can be controlled to sound within the range of angles directly in front of the device, like "the light of a flashlight".

Therefore, we can easily confine the sound to a designated area and prevent the sound from diverging around, which also solves the problem of noise disturbance from the source.

Legal analysis: noise above 60 decibels is considered nuisance. China's current national standard for deferring is "B 3096-" and "Acoustic Environment Quality Standard", which stipulates the environmental noise limits and measurement methods of five types of acoustic environment functional areas, which are suitable for acoustic environment quality evaluation and management.

There are no unified regulations on the size of square dances in the applicable areas of various standards, and the policies and regulations vary from place to place, which are subject to the local policies and regulations.

Legal basis: Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution

Article 46 When using household appliances, musical instruments or vibrators for other indoor entertainment activities at home, the volume shall be controlled or other effective measures shall be taken to avoid environmental noise pollution to the surrounding residents.

Article 58: Where the provisions of this Law are violated by any of the following acts, the public security organs shall give warnings and may impose a concurrent fine: (1) the use of loudspeakers in areas where noise-sensitive buildings are concentrated in urban areas; (2) Violating the provisions of the local public security organs by organizing entertainment, gatherings, and other activities in public places such as streets, squares, and parks in urban areas, using audio equipment, and causing excessive noise that interferes with the surrounding living environment; (3) Failing to take measures in accordance with the provisions of articles 46 and 47 of this Law to emit environmental noise from the home room that seriously interferes with the lives of surrounding residents.

Legal analysisNoise above 60 decibels is considered nuisance. The relevant laws and regulations stipulate the environmental noise limits and measurement methods of five types of sound environment functional areas, which are applicable to the evaluation and management of sound environment quality. Noise limits are specified:

Category, Daytime, Night, Class 0, 50 dB, 40 dB, Class 1, 55 dB, 45 dB, Class 2, 60 dB, 50 dB, Class 3, 65 dB, 55 dB, Class 4, 70 dB, 55 dB. Applicable areas of various standards (1) Category 0 standards are applicable to areas that need to be quiet such as recuperation areas, high-end villa areas, and high-end hotel areas. This type of area located in the suburbs and villages is strictly implemented at 5 decibels stricter than the 0 class standard.

2) Category 1 standards are applicable to areas dominated by residential, cultural and educational institutions. Rural living environments can refer to the implementation of such standards. (3) Category 2 standards are applicable to residential, commercial and industrial mixed areas.

4) Category 3 standards apply to industrial zones. (5) Category 4 standards are applicable to the areas on both sides of the road traffic arteries in the city, and the areas on both sides of the inland waterway that pass through the urban area.

Legal basisLaw of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution》 Article 41 The term "noise from social life" as used in this Law refers to the sound generated by human activities that interferes with the surrounding living environment except for industrial noise, construction noise and traffic noise.

The size of the square dance** should not exceed 55 decibels during the day and 45 decibels at night. If it is exceeded, it will disturb the people.

Legal analysis: 60 dB or more.
