Noise mining in residential buildings
it is understood that if there is noise pollution in residential buildings in our city, you can complain to the environmental protection department and law enforcement department. The environmental protection department is mainly responsible for the treatment of commercial noise, such as the use of air conditioners, cooling towers and other equipment and facilities that may proce environmental noise pollution in commercial business activities. If the identified noise exceeds the national standard, law enforcement will be sent to deal with it; For cases not involved in noise monitoring, such as residential high pitched speakers disturbing residents, the law enforcement department can directly order them to correct or impose a fine; If there is serious noise interference in the middle of the night, the public can also call the police“ The problem of noise involves all aspects. The relevant departments should cooperate with each other and strengthen law enforcement. In particular, they should strictly control the examination and approval of certificates, so as to stop the occurrence of noise from the source. " Law enforcement department of a department head told reporters< In addition, noise procers should consciously rece noise pollution. For example, business operators can start from paying attention to business hours and try to avoid doing business ring owners' rest hours; If it cannot be avoided, measures should be taken to eliminate or rece noise decibels. At the same time, residents can take measures to prevent noise, such as using sealed balcony, installing double-layer sound insulation glass, etc., to rece the probability of noise from doors and windows
1 China's residential indoor standard is 10 dB lower than the local environmental noise standard. Because there are many small factories close to residential buildings in Chinese cities, the indoor noise standard can be divided into residential and non residential buildings. Generally, it should not be lower than the ambient noise standard of the area where it is located by 20 dB, which is stipulated according to the purpose of the room
(2) the indoor noise standard of residential buildings is formulated according to the requirements of quiet life and the environmental noise standard of the area, with reference to the conditions of residential windows (3) the interior decoration noise of residents belongs to the noise pollution of social life (4) according to Article 47 of the general provisions of the law of the people's Republic of China on the prevention and control of environmental noise pollution, when carrying out interior decoration activities in residential buildings that have been completed and delivered for use, the operation time shall be limited, and other effective measures shall be taken to rece and avoid environmental noise pollution to the surrounding residents. The public security organ shall give a warning and may also impose a fine on those who violate these provisions and send out environmental noise that seriously interferes with the life of the surrounding residents from the house (5) those who make noise or interfere with neighborhood life in other ways and do not listen to dissuasion shall be given a warning and may also be fined not less than 100 yuan but not more than 500 yuan< (6) code for sound insulation design of residential buildings, the allowable noise standard for residential buildings formulated by the Ministry of construction, the maximum noise limit for bedrooms and study rooms is 40 dB in the daytime and 30 dB at nightextended data:
according to the law of the people's Republic of China on the prevention and control of environmental noise pollution, the maximum value of sudden noise around residential quarters at night shall not exceed the standard value of 15dB, and the standard for non sudden noise shall be determined according to the applicable area of residential quarters
the standard values of urban five kinds of environmental noise are as follows:
1, Class 0: 50 dB in the day and 40 dB at night
2. Type 1: 55 dB in the daytime and 45 dB at night
class 3 and 2: 60 dB at day and 50 dB at night
4,3: 65 dB at day and 55 dB at night
5,4: 70 dB in the day and 55 dB at night
The noise standard for residential areas is between 45 dB and 55 dB
according to China's "noise emission standard for social life environment", the noise standard for residential areas is between 45dB and 55dB, which is equivalent to a volume at which two people can hear each other clearly when they speak in a room. If the volume exceeds this, it can be regarded as noise nuisance
The noise level of 30-40 DB is a quiet normal environmentmore than 50 decibels will affect sleep and rest. Due to lack of rest, fatigue can not be eliminated, normal physiological function will be affected to a certain extent
70 decibels interfere with the conversation, resulting in upset, inattention, affecting work efficiency, and even accidents
long term working or living in the noise environment above 90 dB will seriously affect hearing and lead to other diseases

extended data
algorithm principle of world general noise standard
the noise standard is based on Nyquist theorem, that is, the thermal noise generated by the irregular thermal motion of the electron e to the thermal equilibrium of the resistance at temperature T, its noise power is
P = KTB
where k is Boltzmann constant, 1.38 × 10J/k T is the physical temperature of the resistance and the bandwidth of the test system, Hz; P is the noise power of resistance output, W
When B is constant, there is a definite relationship between temperature T and noise power P, so t can be taken as the measurement unit of noise value, which is called noise temperature. The first mock exam is based on Planck's blackbody radiation law. When the load satisfies the absolute blackbody condition, the radiation of the single mode is transmitted along the transmission line. p>n = KT
load temperature T is different, which can be divided into three kinds of noise sources: standard high temperature, standard low temperature and standard room temperature. Noise standard higher than room temperature is called standard high temperature noise source; The noise standard with t lower than room temperature is called standard low temperature noise source; The noise standard with t equal to or close to room temperature is called standard room temperature noise source. The standard high temperature noise source is only suitable as the national measurement standard because of the trouble of operation and maintenance
1、 In case of noise and other disturbing phenomena, residents can call 12369 to complain to the local environmental protection department or contact the local urban management department or 110 for settlement
2. What is noise nuisance:
according to China's "noise emission standard for social life environment", the noise standard of residential areas should be controlled between 45dB and 55dB, and the volume exceeding this standard is noise nuisance
-
in the "Regulations on the prevention and control of environmental noise pollution" implemented in 2007, there are clear provisions on noise pollution in residential areas“ Article 38: from 18:00 to 8:00 the next day, interior decoration activities that may proce noise shall not be carried out in residential buildings that have been completed and delivered for use. If indoor decoration is carried out at other times, noise control measures shall be taken to avoid environmental noise pollution. "
-
the regulations also include the stipulation that "any unit or indivial shall control the volume of loudspeakers and audio equipment when using all kinds of loudspeakers and audio equipment in the concentrated area of noise sensitive buildings such as hospitals, schools, institutions, scientific research institutions and residential buildings, and shall not proce disturbing noise"
-
if residents feel disturbed by noise pollution in the residential area, they can first report to the property management company, and let the property management company come forward to coordinate and solve the problem, because the "Regulations" clearly stipulates that "the property management enterprise shall stop the environmental noise pollution in the management area, and timely report to the relevant supervision and Management Department of environmental noise pollution prevention and control." If the communication and coordination of the property management company fails, the owner can call 12369 to complain to the environmental protection department
