What is the noise level in dB coming from a hammer drill in neighboring apartments
Belonging to a particular group is determined by the technical parameters and scope.
A single-mode tool (better known as a dowel) is used to drill small holes in concrete in diameter for the subsequent installation of dowels. In other modes, the device does not work. Models are conditionally divided into 3 classes:
- light (weight does not exceed 3 kg, power - from 400 to 700 W);
- medium (weight - from 3 to 5 kg, power - from 700 to 1200 W);
- heavy (weight - more than 5 kg, power - from 1200 to 1500 W).
The dual-mode tool, in addition to making holes, includes the function of hammer drilling. Models of this type are also divided into 3 classes. A group of heavy perforators has a special mode of operation (chiseling without rotating movements).
The tri-mode tool is preferred for home use due to its versatility. The hammer drill can easily replace a conventional drill and can drill both metal and wooden surfaces. Light class models make a hole in concrete with a maximum diameter of 28 mm, medium class - 32 mm, heavy - 55 mm.
According to the type of drive, hammer drills are:
- electrical (battery);
- pneumatic;
- gasoline.
Advantages and disadvantages of certain models
Before buying a tool, for some time I doubted the advisability of acquiring it, because you can get by with an impact drill or, in the end, a hammer. Now, it is even difficult to imagine how much time and effort would have to be spent on the performance of this or that work. To determine which drill to choose, you should familiarize yourself with the pros and cons of different types of designs.
Among the main advantages of a percussion instrument:
- convenient application, the impact energy does not depend on the pressing force;
- the ability to use the device as a drill or screwdriver;
- nozzles and control handles in the kit help to perform installation of any complexity;
- a failed unit can be easily replaced without outside help, which will extend the operating period.
If you go through the individual models, then each has its pros and cons. For instance:
- Small in weight structures with a horizontal fixation of the engine in the hands are easier to hold, but there is more sense from perforators with a vertical motor;
- For large-scale repairs, pneumatics are more suitable, mechanics will cope with minor tasks;
- Battery-type models operate independently of the network, but an autonomous resource makes the structure heavier;
- In the presence of a gearbox, it is possible to set a suitable speed;
- Fancy models are multifunctional, but complex mechanics imply special maintenance and additional expenses for repairs;
- The battery model makes a lot of noise in the operating mode (there is no such effect in stationary devices), it also becomes necessary to control the charge level;
— The cost of a high-quality universal tool cannot be low.
Soundproofing is
Well, except for the ritual dismemberment and mass burning of offenders.
Here 75dB, at the perforator somewhere the noise level is on the border of 80-110 dB.
It is interesting at airfields along the takeoff field, in which headphones they move ...
| Usually they buy aviation + droplets. Droplets in the ears, aviation on top and should help.
Well, the law - we have time to limit noise. |
| Yes, they are law-abiding parasites, from 9.00 to 22.30 they hammer, with everything that comes to hand, since the action takes place exactly one floor higher, the guard is simple.
I would not even so much adults as children. In the evening I will google, so offhand why I remembered aviation, there is also the noise level from aircraft engines at the level of 140 dB. Somehow hearing saves people. |
According to the law, it is allowed to carry out repair work from 9.00 to 19.00 and only on weekdays, on weekends it is generally forbidden to use construction equipment that creates noise and vibration.
Threat if they make such a noise, there should have been a petition that they warned that there would be noise and dust, and you agreed with this with your signature. Did you go too far about 100 dB? Noise-canceling earphones that are used at airports - ordinary construction (25 dB) sound pressure over 85 dB the first, second drill should not be heard, you can also push cotton wool into your ears further already come with "electronics" and their prices are much higher.
What to look for when choosing a perforator
The choice of a perforator for the home begins with determining the scope of its application, the volume and complexity of the work. Based on this, models with the appropriate technical characteristics are selected.
The power of models on the market is in the range of 450-2000 watts. Household appliances have a maximum of 900 watts. If the tool is purchased for minor home repairs, then a power of 700-900 W will be enough. Impact devices up to 1500 W are recommended for drilling thick walls, removing tiles and other works of medium complexity. With regular use, preference should be given to a professional look (1200-2000 W).
The impact force reflects the indicator of the produced energy directed to the treated surface. Based on these data, it is possible to determine with what efficiency and speed the work will be performed. For domestic use, models with an impact force of 2.6 to 4.5 J are suitable. The maximum indicator of a professional device is 20 J.
An important component of the technical characteristics is the number of modes. Hammer drills for home use can have one or more modes from the following list:
- drilling (function of a conventional drill);
- impact drilling;
- blow (jackhammer function).
The three-mode tool is universal, so it will always come in handy on the farm.
The speed of rotation / shock indicates the number of movements (rotational and translational) reproduced in a certain time. In different models, this figure varies from 230 to 2300 rpm. For domestic use, 1000-1500 rpm is enough at a frequency of 4000-4500 strokes per minute.
Most rotary hammers have two types of cartridges: SDS+ and SDS max. The first type is installed on the household model, it can be used with a drill up to 15 mm in diameter. SDS max is completed on professional tools.
It is good if the selected model is endowed with additional functions:
- speed switch button;
- anti-vibration system;
- locking element of the switch;
- a clutch that prevents jamming of the drill, etc.
On the shelves of shops there are professional and household punchers. When selecting, it should be taken into account that the first type of tools is designed for constant loads, and household appliances are designed for occasional use. I, in turn, would recommend the golden mean for home use - a semi-professional tool of a reliable brand.

Quiet hours limitation of noise works
Periodically adding to this musical accompaniment in the form of the most miserable popsyatina, which is sometimes heard from two radio receivers located at different ends of the construction site at once; and then some kind of mumbling is added to this: either news, or prayers.
According to GOST, constant exposure to noise at a level of 80 decibels or more is considered harmful. Noise of 130 decibels causes a person to experience physical pain. 150 decibels is an unbearable sound pressure level, a person simply loses consciousness. At 180 decibels, the metal begins to break down, and for a person this level of noise is considered fatal.
90 Very noisy loud screams, freight railway car (seven meters away)
95 Very noisy subway car (7 meters outside or inside the car)
100Extremely noisy orchestra, subway car (intermittently), thunder
The maximum allowable sound pressure for the player's headphones (according to European standards)
105 Extremely noisy in an airplane (until the 80s of the twentieth century)
110 Extremely noisy helicopter
115 Extremely noisy sandblaster (1m)
120 Almost unbearably jackhammer (1m)
125 Almost unbearable
130 Pain threshold aircraft at the start
Well, okay, in order to hear all this less, especially the sound of grinders, on the third day I bought myself industrial headphones - otherwise you can go crazy. When the grinders start working, it takes me a few minutes to, well, how to put it mildly, to feel uncomfortable. And indeed - if you look at the tables above - such noise is both harmful (even GOST is mentioned), and "extremely noisy", somewhere close to the pain threshold.
They drink everywhere. Wherever you go - everywhere these men with grinders saw stone, then iron. The fact that both workers and their employers do not give a damn about others - this makes no sense to discuss. Another thing is surprising - in all the last years I have NEVER seen these people even take care of themselves - not once have I seen one of them work in headphones. It's strange, isn't it?
And it can be even more interesting - I have repeatedly seen similar scenes with grinders on Kirovka, during the day; for example - repair of pavilions with attractions, etc. - well, there is always something to file or grind. Well, the one who hires workers for some kind of work does not give a damn about the inhabitants of the surrounding houses, but they also scare customers away from themselves and from their neighbors. Strange, isn't it?
I can't find any other explanation for this other than what's in the title. Those. if a moron loves decibels, then no considerations of either one's own health or losses for business (you can only mention the ethics of relationships like this - in brackets) do not matter.
How to solve the dilemma of high noise level or good cleaning quality
By carefully studying the range of vacuum cleaners offered by modern manufacturers, the characteristics of these devices, it is easy to see that usually filterless devices have a higher noise level than their dust-fighting counterparts equipped with filters. In this case, the consumer interested in purchasing a low noise vacuum cleaner is forced to make a choice. Which vacuum cleaner is preferable in this situation - a noisier, separatory model, or a device with a moderate noise level with a HEPA filter?
When solving this dilemma, do not forget about the main thing - the vacuum cleaner must provide a good cleaning quality that has not changed over the years. Unfortunately, vacuum cleaners with HEPA filters are not suitable for solving this problem, since the presence of filters will certainly make itself felt after a short period of time. The suction power of the device will decrease significantly and it will no longer be able to fully perform its functions. What is the use of a low noise level when the device itself cannot cope with cleaning the apartment from dust and it will have to be changed?
A separator vacuum cleaner, sometimes working more noisily, will be able to please its owners with good cleaning quality throughout its entire service life, and this is the main parameter for a vacuum cleaner.
If the vacuum cleaner itself works stably, with high quality in the process of one cleaning and is able to serve faithfully for many years, its owners are unlikely to be annoyed by a slightly louder sound, they will simply stop paying attention to it
If the vacuum cleaner has such an option as a power regulator, you can set the noise level that will be most comfortable for you. As an example, the model of the Pro-Aqua separator vacuum cleaner is perfect, which perfectly copes with its main duty - ensuring cleanliness and sanitary order in the room.
As always, before inviting readers to pay attention to the modern vacuum cleaner model, we will use the reviews of real customers. What impressions did they have from the operation of the Pro-Aqua separator vacuum cleaner?
Pro-Aqua vacuum cleaners are often purchased by families with small children, and the owners of these devices are very satisfied with the quality of cleaning, humidification and aromatization of the air in the apartment. Many users note the absence of the smell of dust during cleaning, excellent cleaning of carpets and upholstered furniture from dust and pet hair. As for the noise level, it is quite comfortable even for small children, especially since it can be reduced using the power control.
How to determine the noise level of a vacuum cleaner
Tests of vacuum cleaners for noise level, as well as any other equipment, are carried out in specially created, standard conditions, which are often fundamentally different from the conditions in which the device is to work. Establishing standard conditions for noise measurement is of great importance. It is they that make it possible to compare the noise level of different models, to determine how this or that innovation in the design of the device affects this parameter.
The noise level of the vacuum cleaner is measured at the factory. To do this, the finished device is connected to the network, a microphone is placed at a distance of 30-50 cm from it, a device for recording the noise level. Over a period of time, the noise level is measured and recorded. This procedure is repeated 2-3 times, this allows you to find a constant value of the noise level.
Noise law in the apartment what's new
According to this bill, Muscovites can do noisy repairs:
- on working days from 8-00 to 21-00;
- on weekends - from 10-00 to 22-00.
But construction noise must be interrupted and noise cannot be made for more than six hours in a row. This also applies to everything else - loud banquets in apartments, etc.
Individuals will first pay a symbolic amount of a fine - 500 rubles, but the challenge to the court makes many people think and change their behavior, taking into account the interests of other people. For legal entities, the fine can be much higher, and they can even suspend the activities that led to the noise for three months. TOPIC!
Greetings to all who decided to read my recommendations regarding the choice of a good puncher
In this article I will try to describe as clearly as possible what you need to pay attention to when buying a tool. The presence of a wide range in a specialized store rather complicates the task for buyers, so a few practical tips will not hurt
What determines the noise level of vacuum cleaners
It is believed that the noise level of the vacuum cleaner should not exceed 80 dB. What determines the noise level of a vacuum cleaner? There are many parameters on which the noise level of vacuum cleaners depends. These include:
- build quality;
- device design;
- fan power level;
- the presence / absence of filters in it;
- nozzle used;
- the dimensions of the room in which the device operates;
- type of flooring.
If you check how the vacuum cleaner will work in a large room and in a tiny kitchen, it turns out that in a small room the sound of the vacuum cleaner will be much louder, by about 8 dB.
If for any good reason it is of fundamental importance for you that the vacuum cleaner works as quietly as possible, when buying an appliance, be sure to ask the sales assistant to turn on the vacuum cleaner. The noise level that the device emits may initially not suit you.
In this case, you should not succumb to the persistent assurances of the seller, who will claim that the noisy operation of the device is due to its high power consumption.
The noise level directly depends on the quality of the assembly and the materials used for this, but not on the power consumption of the device. An example can be cited as evidence. Let's take a Philips FC9170 vacuum cleaner designed for dry cleaning, which has a HEPA filter.The power consumption of this device is high, it is 2200 W, the noise level of this model does not exceed the permissible norm, it reaches 78 dB.
The Ariete 2799/2 A model is also designed for dry cleaning, the cyclonic filtration system of this vacuum cleaner is based on a HEPA filter. The power consumption of the device is 1300 W, its noise level exceeds the norm, it is 83 dB. The Pro-Aqua Vivenso separator vacuum cleaner, designed for dry and wet cleaning, has a power consumption of 1000 W, while its maximum noise level does not exceed the norm, it does not exceed 70 dB. Based on the above examples, it should be concluded that the reference of sellers that the high noise level depends on the power consumption of the vacuum cleaner is completely untrue.
What does the law say when you can make noise in apartments
Federal Law No. 52-FZ "On the sanitary and epidemiological well-being of citizens" regulates silence in people's apartments. It clearly regulates the time of noise at night and day and time limits:
- on working days of the week, it is allowed to carry out work related to strong noise and vibration from 9-00 to 19-00;
- on weekends and holidays it is forbidden to perform noisy work from 0-00 to 24-00. But more recently, it was possible to do repairs on weekends until 19:00 and start it at 9:00 in the morning. But now weekends and holidays are considered days of silence;
- loud music, dancing and all other loud sounds must be stopped on any day at 23-00. From 7-00 to 23-00 you can make noise, but not much. Noise should be 40 dB. Such sounds are similar to the sound from a working computer system unit, and anything that is much louder is illegal. At night, the permissible noise level is reduced to 30 dB. At night, it is also forbidden to shout loudly, sing, play musical instruments and use loud household appliances and pyrotechnics.
Of course, we are all living people, and if you have a wedding, birthday or other family celebration, then it is best to negotiate with the neighbors, and they will understand you. But if a neighbor makes noise within the law (coughs loudly, walks and creaks the floor, etc.), then this is not a violation of the law and only good relations with him can lead to silence in your apartment.
