Accommodation in major cities- it's not just traffic jams, the metro and a lot of people. It is also a loud, constant noise, including that coming from neighbors’ apartments. In the article you will find legislative prohibitions regarding noise generated, instructions for punishing noisy neighbors and a sample statement to the police as one of the measures to get rid of noise.

Currently, the night silence of the capital is protected by July 12, 2002 “On maintaining the peace of citizens and silence at night in Moscow.” In the Moscow region - Law of the Moscow Region No. 16/2014-OZ dated March 7, 2014 “On ensuring peace and quiet of citizens in the territory of the Moscow region.” The above laws are known to the public as silence laws.

To guard the daytime peace of citizens are sanitary standards headed by March 30, 1999 “On the sanitary and epidemiological well-being of the population.”

Law on silence in Moscow and the region: when to make noise from January 1, 2019?

Let's say right away that this moment Our country's legislators are considering several bills, the final adoption of which will make significant adjustments to the time frame limiting the period of permissible noise.

Night time, according to current law Moscow, is determined by the time period starting from 23 o'clock to 7 o'clock in the morning.

The project is currently at the stage of consideration in the Moscow City Duma legal act, according to which a ban will be introduced on the reconstruction and (or) redevelopment of residential premises in apartment building, other repair work in the specified premises from 19 to 9 hours and from 13 to 15 hours. Accordingly, the phrase “at night” is excluded from the title of the law itself, and finally there will be a statutory time limit for noise in an apartment during the day.

In the Moscow region, it is not permissible to disturb peace and quiet:

• from 21 to 08 hours on weekdays;
• from 22 to 10 o'clock on Saturday, Sunday and holidays;
• from 13 to 15 hours daily in residential apartment buildings by using loud sound-reproducing devices or when carrying out repairs, reconstruction, redevelopment of residential premises.

For the country as a whole, rationing by time of day is determined SanPiN 2.1.2.2645-10 as follows: daytime - from 07:00 to 23:00, respectively, night time - from 23:00 to 07:00.

The bill on amendments to the Federal Law “On the sanitary and epidemiological welfare of the population” plans to introduce the concept of “morning time”, defining night from 22 to 06 o’clock, and morning from 6 o’clock to 10 o’clock. Moreover, the permissible noise level in residential premises for night time will apply to Saturday morning, Sunday morning and non-working holidays.

Premises and areas where noise is prohibited at designated times

• Apartments, premises common use in residential apartment buildings, dormitories, residential buildings and living quarters;
• Adjacent areas, courtyard driveways, playgrounds, children's and sports grounds in residential neighborhoods;
• Premises and territories of medical, educational, rehabilitation, sanatorium and resort organizations and organizations providing temporary stay of citizens;
• Territories of horticultural, dacha, and vegetable gardening associations of citizens.

In residential premises transferred for use under contracts social hiring, the obligation of the tenant “to use the residential premises, taking into account the observance of the rights and legitimate interests of citizens and neighbors living in the residential premises (house)” also implies the need to comply with the law on noise in an apartment of 2017 (standards limiting the maximum permissible noise level).

Limit values ​​for permissible noise levels in apartments

• During the day: 55 dBA;
• At night: 45 dBA.

In the daytime, it is allowed to exceed the noise limit for residential premises, and in areas adjacent to railway tracks and highways - .

For comparison:

30 dBA – human whisper, ticking of a wall clock;

40 - 45 dBA – normal speech, conversation;

55 dBA – passenger car;

75 dBA – vacuum cleaner;

78 dBA – baby crying;

90 dBA – the cry of an adult;

95 dBA – hammer drill;

120 dBA – jackhammer.

Actions that disturb peace and quiet during prohibited times:

• Use of all kinds of sound-reproducing devices (TVs, radios, tape recorders, tape recorders);
• Playing musical instruments, singing, whistling, shouting and other actions with loud sound;
• Using the sound of a car security alarm;
• Use of pyrotechnics;
• Construction, repair, unloading and loading works; earthworks– for MO;
• Other actions (permissible for Moscow).

Does not apply to:

• actions aimed at preventing crime, eliminating the consequences of accidents, emergencies and natural Disasters, performing work that supports the functioning of life support facilities for people;
• holding official cultural and sporting events, religious ceremonies and rituals;
• actions for which responsibility is established by administrative legislation.

Is it possible to legally punish noisy neighbors?

Violating the peace and quiet of citizens during the daytime is a violation of sanitary standards, the observance of which is monitored by sanitary and epidemiological authorities (Rospotrebnadzor). They also have special devices for recording noise levels to detect violations. Accordingly, if neighbors lead a noisy lifestyle during the daytime, then the application must be submitted to the Rospotrebnadzor office, whose employees are empowered to draw up reports on administrative violations.

Noise at night, as a rule, is considered to be an encroachment on public order and tranquility, protected by administrative law. Police officers are authorized to draw up protocols on such administrative offenses. In this case, recording the excess of the permissible noise level using special devices is not required.

Sample statement to the district police officer regarding noisy neighbors -

The application can also be submitted orally. The district inspector is obliged to write it down from the applicant’s words and register it properly at the police station on duty.

Latest news 2019

According to data coming from the administrations of the cities where the 2018 World Cup matches will take place, the Russian Federation law on silence will not apply to the period of the 2019 World Cup events.

In the last article we touched on the topic of cleaning ears with cotton swabs. It turned out that, despite the prevalence of such a procedure, self-cleaning of the ears can lead to perforation (rupture) of the eardrum and a significant decrease in hearing, up to complete deafness. However, improper ear cleaning is not the only thing that can damage our hearing. Excessive noise that exceeds sanitary standards, as well as barotrauma (injuries associated with pressure changes) can also lead to hearing loss.

To have an idea of ​​the danger that noise poses to hearing, it is necessary to familiarize yourself with the permissible noise standards for different times of the day, as well as find out what noise level in decibels certain sounds produce. In this way, you can begin to understand what is safe for your hearing and what is dangerous. And with understanding comes the ability to avoid the harmful effects of sound on hearing.

According to sanitary standards, the permissible noise level, which does not harm hearing even with prolonged exposure to the hearing aid, is considered to be: 55 decibels (dB) during the daytime and 40 decibels (dB) at night. Such values ​​are normal for our ear, but, unfortunately, they are very often violated, especially within large cities.

Noise level in decibels (dB)

Indeed, the normal noise level is often significantly exceeded. Here are examples of just some of the sounds we encounter in our lives and how many decibels (dB) these sounds actually contain:

• Spoken speech ranges from 45 decibels (dB) to 60 decibels (dB), depending on the volume of the voice;
• Car horn reaches 120 decibels (dB);
• Heavy traffic noise – up to 80 decibels (dB);
• Baby crying – 80 decibels (dB);
• Operation noise of various office equipment, vacuum cleaner - 80 decibels (dB);
• Noise of a running motorcycle, train - 90 decibels (dB);
• The sound of dance music in a nightclub is 110 decibels (dB));
• Airplane noise - 140 decibels (dB);
• Noise from repair work – up to 100 decibels (dB);
• Cooking on a stove - 40 decibels (dB);
• Forest noise from 10 to 24 decibels (dB);
• Lethal noise level for humans, explosion sound - 200 decibels (dB)).

As you can see, most of the noises that we encounter literally every day significantly exceed the permissible threshold. And these are just natural noises that we cannot do anything about. But there is also noise from TV and loud music, to which we expose our hearing aids. And with our own hands we cause enormous harm to our hearing.

What noise level is harmful?

If the noise level reaches 70-90 decibels (dB) and continues for quite a long time, then such noise with prolonged exposure can lead to diseases of the central nervous system. And prolonged exposure to noise levels of more than 100 decibels (dB) can lead to significant hearing loss, including complete deafness. Therefore, we get much more harm from loud music than pleasure and benefit.

What happens to hearing when exposed to noise?

Aggressive and prolonged noise exposure to the hearing aid can lead to perforation (rupture) of the eardrum. The consequence of this is hearing loss and, as extreme case, complete deafness. And although perforation (rupture) of the eardrum is a reversible disease (i.e., the eardrum can recover), the recovery process is long and depends on the severity of the perforation. In any case, treatment of perforation of the eardrum is carried out under the supervision of a doctor, who chooses a treatment regimen after examination.

In modern cities, noise pollution is a huge problem that every resident faces. apartment building. Loud noises in an apartment can make life unbearable. The noise coming from neighboring apartments can seriously harm a person’s health, interfering with proper rest and sleep.

In order to avoid such a situation, it is important to know whether there are noise standards, where to go if neighbors violate established by law standards, and how to properly prove that noise has exceeded the permissible level.

Methods for measuring noise in residential areas

How to measure the noise level in an apartment? There are several ways:

1. Using specialized technical devices

Professional sound level meter- a device that allows you to measure sounds in decibels. The measurement is performed using a microphone, and the results are displayed on the device screen. Measurements are taken at several points and displayed average level noise.

1. Using computer programs

Modern technologies make it possible to measure using programs installed on smartphones and tablets. Using a microphone, the device receives information about the noise level and performs an analysis.

1. Call a specialist

Services for measuring noise levels in an apartment can be provided by:

The first thing to do– , which will indicate the applicant’s details, address, requirement to measure the noise level and its intended source.

To ensure that the procedure is carried out promptly, a Rospotrebnadzor employee can be called by phone.

The measurement procedure is carried out in several stages, and upon completion, a report is drawn up that reflects the results of the study.

The danger of high-pitched sounds for humans

Very often the effect of loud sounds on the human body is underestimated. This is due to the fact that the consequences of such influences do not appear immediately, but after some time.

Under the influence of constant noise attacks, a person’s hearing decreases and their general physical condition worsens:

• labor productivity and efficiency sharply decrease;
• noise also has a negative impact on the ability to communicate and communicate;
• the quality of optical signal reception decreases;
• learning efficiency decreases;
• the emotional situation in the team worsens;
• noise also affects the rate of aging and an increase in the number of heart attacks;
• negatively affects the immune system and nervous system.

Very often, children growing up in areas with high noise pollution experience problems with concentration, the ability to think logically, read and speak.

What happens to hearing when exposed to noise?

Prolonged exposure to noise or high-pitched sounds can seriously damage a person’s hearing system, even to the point of rupturing the eardrums. As a result, hearing decreases, sometimes complete deafness occurs.

There are different noise levels. At 35–40 decibels, sleep is disturbed, at 70, the nervous system suffers, mental illness can appear, vision can deteriorate, and even the composition of the blood can change for the worse.

Constantly excessive background noise is fraught with increased irritability and fatigue.

There is also a deadly sound level - when the sound reaches 200 decibels a person dies.

Maximum permissible noise level in the room, the norm according to the law of the Russian Federation

The permissible noise level is established by law by the state. The legal framework for assessing noise levels includes:

• Federal Law No. 52 of March 30, 1999 “On the sanitary and epidemiological welfare of the population.”
• Sanitary standards SN 2.2.4/2.1.8.562-96 “Noise in workplaces, in residential and public buildings and in residential areas.”

It should be noted that in each subject of the Russian Federation there are also local laws on silence, which describe in detail the time frame of restrictions, as well as a system of fines for violating established norms.

Night hours have different durations and depend on the geographical and climatic characteristics of different regions of the Russian Federation and take into account established traditions.

The time frame for construction and repair work – the source of the loudest noise – is specified separately.

In addition, most regions have introduced a kind of "" from 13:00 to 15:00, in order to protect children and the elderly from noise during the afternoon rest.

It is worth noting that many noises surrounding a person in ordinary life significantly exceed the norm.

For example, the noise of a moving elevator reaches 43 dB, a calm conversation - 63 dB, the noise of a vacuum cleaner - 80 dB.

It is impossible to avoid these everyday sounds, but they do not pose a danger when the impact on a person’s hearing is short-lived. Systematic noise that goes beyond the norms poses a danger to human health.

Information on the regions of the Russian Federation regarding noise time can be studied at the link -.

During the daytime

In accordance with established standards, the noise level in residential premises during the day should be at 40 dB. In this case, an excess of 15 dB is allowed, and thus the maximum permissible noise level during the day is 55 dB.

At night time

The permissible noise level at night is 45 dB. The following actions are not allowed at night:

• Turning on music devices and TVs at high volume.
• Stomping, loud singing, etc.
• Launch of pyrotechnic products.
• Rearrangement of furniture and repairs.

These restrictions are lifted in the event of force majeure, mass events or actions of emergency services.

Noise standards during construction and renovation in an apartment building in a residential area

Repair and construction works, which are accompanied by a high background noise, must also be organized in accordance with the standards.

Their total duration should not exceed three months, and within one day - 6 hours continuously.

The timing is determined by local silence laws, usually from 9 a.m. to 7 p.m. Repair work is also prohibited from 13:00 to 15:00.

What do sanitary standards for noise in a populated area include?

If you experience discomfort from excessive noise in the apartment, you should submit an application to Rospotrebnadzor, the sanitary-epidemiological service or an independent organization licensed to carry out this activity.

Specialists who arrive on such a request have with them professional equipment that allows them to determine the noise level with high accuracy.

Measurements are made in accordance with special technologies that involve measuring noise at different points in the room, drawing the average value and comparing it with acceptable standards.

The measurement protocol ultimately indicates the frequency and dynamic levels noise, and sometimes the effectiveness of the existing sound insulation.

If you decide to use the help of Rospotrebnadzor specialists, you can be sure:

• noise level measurements will be carried out in accordance with GOSTs and standards;
• equipment for measuring work undergoes regular checks and is in good working order;
• the price for measuring the noise level is not overpriced, and varies within 500 rubles per measurement at one point in the room. total cost the cost of visiting Rospotrebnadzor specialists during the day will not exceed 5 thousand rubles, and at night – 10,000.

You can use the services of private companies; in this case, upon completion of the examination, you will also receive a document containing a complete list of calculations and recommendations.

Why is expertise needed?

An acoustic examination, officially carried out by specialists, is needed in order to obtain confirmation of a violation of the norms of the legislation of the Russian Federation.

The examination carried out by Rospotrebnadzor is appropriate in situations where the matter is being investigated judicial procedure. Measurements taken on your own will not be suitable in this case - the court needs expert opinions from specialists.

Important! In a situation where an acoustic examination is carried out by court decision, all costs after the hearing are borne by the losing party.

The paper documenting the violation, issued by Rospotrebnadzor specialists, will become your main evidence in court and will help calm down excessively noisy neighbors.

Attention! There are circumstances in which it does not make sense to carry out an examination even in cases where the norms are clearly violated. There are reasons that cannot be controlled, for example, a child’s crying.

Responsibility for violation of rules by neighbors

You can be held liable for failure to comply with sanitary standards if the violations are systematic.

If the violator ignores the requests of other people and they seek help, then for the first time a fine of 1–2 thousand rubles is issued. In case of repeated violation, the amount of the fine doubles, and if the violations are chronic, a fine of two minimum wages is imposed.

If extraneous sounds interfere with normal life in the apartment, you should contact the prosecutor's office, Rospotrebnadzor, the police and the Criminal Code. Having collected the full evidence base and by going to court you can win the case.

High level noise is dangerous not only for a person’s emotional comfort; loud sounds can also negatively affect his physical condition. Therefore, it is so important to carefully monitor the noise level in the apartment, and to defend your rights if sanitary noise standards are not met for some reason.

If neighbors or other persons do not maintain order at night, you will have to use special measuring instruments and record excesses of the permissible decibel level in a separate protocol.

General information

The law provides for noise standards that are often not observed in apartment buildings. In the daytime it should be no more than 40 dB, and at night - 30 dB.

This level is equal to a conversation in a calm tone. Most sounds significantly exceed the established limits. For example, a baby's cry is 80-110 dB. The sound of a passing car is 70 dB. The lethal norm is 200 dB.

At the federal level, there is no uniform law on silence that regulates noise levels everywhere. Subjects of the Russian Federation adopt such laws independently. Moscow has Law No. 42, which was adopted back in 2002. In many regions such laws were adopted later. IN Stavropol region, The Law on Silence was adopted only in 2010 (Law No. 117-kz of December 28, 2010).

The Civil Code of the Russian Federation and the Housing Code of the Russian Federation allow citizens to own, use and dispose of their property, the list of which includes residential premises of any form of ownership.

The classification of noise that affects humans is established by the Federal Sanitary Rules, Norms and Hygienic Standards adopted by Resolution of the State Committee for Sanitary and Epidemiological Supervision of October 31, 1996 No. 36.

Measures to ensure peace and quiet of citizens, as well as public order, are established by regional regulations.

Noise standards in an apartment building

They are installed federal legislation. Measurements are the responsibility of organizations licensed by Rospotrebnadzor.

Acceptable values ​​at night and during the day

Noise standards are established in section 6 of the State Committee for Sanitary and Epidemiological Supervision Resolution No. 36. The maximum permissible standard in the daytime is considered to be 40-80 dB. At night, the noise level should not be higher than 45-50 dB.

The requirements apply to noise sources of any origin - construction and repair work, sound-reproducing and sound-amplifying devices, etc. Small deviations from the norm are allowed, but you should act within reason, without violating the legal rights of neighbors and residents of the house.

How to measure?

For measurements, an electronic sound level meter is used, manufactured according to the standards of GOST RF 53188.1-288. The device is a microphone to which a voltmeter calibrated in dB is connected. The device uses several sets of filters that are responsible for monitoring noise intensity.

If a citizen has such a device, then he can measure the noise level himself. Typically, measurements are carried out by organizations and specialists from Rospotrebnadzor.

A citizen who is periodically disturbed by noisy neighbors has the right to contact the regulatory authorities. Experts take measurements during the day and at night. There may be a fee for their departure. Use services third party organization It is advisable when the noise is periodic, for example, when a neighbor turns on a generator or connects another device.

Specialists record the noise level and enter the indicators into a special protocol. It displays the date of measurements and noise level. The protocol must be signed by specialists and the citizen initiating the inspection.

In the future, such a document can be used as written evidence in court - in case of systematic violation of the rights of the residents by the neighbor.

Repair time

At the general federal level, it is set from 9 a.m. to 7 p.m. In regions, such time frames may vary. The days when repair work is carried out should also be taken into account.

Noisy repairs are prohibited on weekends. On weekdays, it should be performed with breaks between 13:00 and 15:00 - for the rest of citizens, especially children and the elderly.

Until what time is it possible and when is it not possible?

At the federal level, the time is considered to be from 23:00 to 7 am inclusive. On holidays and weekends, noise is prohibited from 10 am to 10 pm. In St. Petersburg, repair work is allowed to be carried out on weekends, but only from 8:00 to 12:00.

The prohibition on carrying out repair work at other times concerns the prohibition of using rotary hammers, drills, hammers and other noisy devices. Also, the total duration of repairs should not be more than three months.

Are there exceptions to the rules?

assumes some exceptions to . Making noise is allowed in the following situations:

• When holding mass holiday events. For example, in the Stavropol Territory, loud noise is acceptable from 23:00 to 2 am on January 31-1, when pyrotechnics can be launched. Similar exceptions are provided in other regions.
• At restoration work– any construction and technical activities related to road repairs and infrastructure restoration.
• When conducting operational search activities and investigative actions, although certain investigative actions are also prohibited at night, for example, a search, except in urgent cases.

A complete list of exceptions to restrictions is contained in regional regulations.

Responsibility for violation

It is regulated by regional administrative codes and laws.

In 2019 in Moscow, the fine for citizens is 500-3 thousand rubles. Officials they will pay 2-10 thousand rubles. Legal entities can pay up to 30 thousand rubles.

The amount of liability regularly changes upward, which is especially important for large cities.

To bring neighbors to justice, you will need to call the police or contact the local police officer, who will draw up a report on administrative offense and will take it to court. Administrative cases are considered by the magistrate at the place where the offense was committed.

In practice, it is difficult to bring neighbors to administrative responsibility, since the police sometimes ignore such unpleasant domestic situations and limit themselves to warnings.

It is recommended to be able to negotiate with neighbors, especially if noisy, lengthy repairs are necessary. Some citizens post notices in their entrances, including apologies for temporary inconveniences, which is quite rational and reasonable.

If the conflict with neighbors is systematic, then in order to hold them accountable, it is recommended to seek support from a competent lawyer.

Video about noise laws

Attention!

• Due to frequent changes in legislation, information sometimes becomes outdated faster than we can update it on the website.
• All cases are very individual and depend on many factors. Basic information does not guarantee a solution to your specific problems.

Noise level- this is the level of a combination of various sounds that does not cause increased anxiety in a person and does not cause significant changes in the indicators of the functional state of systems and analyzers that are sensitive to noise.

This is a noise level that does not cause anxiety or any other physiological or mental changes in a person, usually not exceeding 55 decibels (dB). High noise level is fraught with great danger. To understand the impact noise has on hearing, you need to have an idea of ​​the permissible noise standards for different times of the day, as well as know what noise level in decibels different sounds produce. After this, you can understand whether certain sounds are safe for hearing or fraught with danger. Once you understand the importance of noise, you can try to avoid the harmful effects of sounds on your hearing.

Permissible noise levels in apartments and other residential premises.

Permissible noise level standards are determined in accordance with established sanitary standards; a noise level that is not harmful to hearing, even after prolonged exposure to the hearing aid, is considered acceptable. The permissible value is:

• during the daytime permissible noise level equal to - 55 decibels (dB);
• at night, the permissible noise level is 40 decibels (dB).

This value is optimal for our ear. However, in large cities they are usually violated.

Noise level in decibels (dB).

Noise level in decibels- This physical characteristic sound volume measured in decibels (dB). If you look at the level of noise produced by things and machines that are familiar to most people, you will see how often it is exceeded normal noise level. As an example, we will give only a small part of the sounds that surround us in life and how many decibels (dB) they actually contain:

As you can see, most noises significantly exceed the permissible norm. Moreover, the table shows natural background noise, which we, as a rule, cannot influence in any way. And if we also take into account the noise from a working TV or loud music, to which we ourselves subject our hearing aids. Causing great harm to our hearing with our own hands.

What noise level is harmful?

Noise level which, reaching a level of 70-90 decibels (dB), with prolonged exposure to the hearing aid, affects the central nervous system and can lead to its diseases. Noise reaching a level of 100 or more decibels (dB), when exposed for a long time, can lead to significant hearing loss, up to complete deafness. Therefore, listening to music at maximum volume, we get much more harm than pleasure and benefit.

Noise can be divided into 4 main groups, divided into subgroups.

According to the mechanism of occurrence:

• mechanical noise (operation of machines and mechanisms) - created by elastic vibrations of solid and liquid surfaces;
• aero- and hydrodynamic noise that occurs when turbulence appears in a gas or liquid medium;
• We hear electrodynamic noise when an electric arc or corona discharge appears.

The following types of noise are distinguished by frequency:

• low frequency less than three hundred hertz;
• mid-frequency from three hundred to eight hundred hertz;
• high frequency above eight hundred hertz.

According to the noise spectrum:

• wideband (more than one octave);
• tonal (uneven distribution of sound energy with a significant advantage within an arbitrary octave).
