How to solve the problem that the elevator noise can be heard in the bedroom?

How to solve the problem that the elevator noise can be heard in the bedroom? Workaround:

1. You can add a layer of soundproof wall to the room.

2. Use wallpaper, or "soft package" decoration and other decoration materials to make the surface of the wall rougher, so that the sound waves are refracted many times, so as to reduce the noise. For large households, a layer of gypsum board can be installed.

to reduce noise. For small households, cork can be used to cover the walls, and solid wood is used to form geometric shapes at different distances.

ground divides the walls, and then covers them with cork.

3. Indoor ceiling.

If the color of the floor and wall is too bright, it will interfere with the central nervous system of the human body.

It makes people feel distracted and sensitive to noise. Therefore, in the selection of various lamps and decorative materials for interior decoration, special attention should be paid to soft light.

4. The sound-absorbing effect of cloth is well known, so the use of fabric to eliminate noise is also a more common and effective method. Tests have shown that the sound absorption effect and effect of draped and tiled fabrics are the same, such as curtains, carpets, etc., and the sound insulation effect of curtains is the most important.

There are two methods, one is to reduce the noise of the elevator, and the other is to insulate the bedroom.

1. It is recommended to reduce the noise of the elevator, first look at what part of the elevator is the noise, machine room noise, hoistway noise, etc., the elevator is mostly low-frequency noise, it is best to reduce the vibration of the elevator equipment, and the effect is better. The property will come forward to fund the noise control company to deal with it.

2. Bedroom sound insulation is to lay sound insulation felt vibration damping pads and other materials on the wall to improve the sound absorption and insulation ability of the wall.

Note. If the elevator is not maintained daily, the safety of the elevator can not be guaranteed, if the elevator needs to be refueled and not refueled, it will cause the wear and tear of the elevator mechanical parts, so that the service life of the elevator is greatly shortened, and the elevator cannot be used normally.

In the process of using the elevator, some elevator users in order to reduce costs and save money, find temporary workers or unqualified companies to do elevator maintenance, once there is a safety problem, even the responsible unit can not be found. If it is maintained by the elevator manufacturer or a qualified professional company, on the one hand, the maintenance technology and quality are ***, and on the other hand, once there is a problem, someone is responsible.

Then make the soundproofing of the bedroom a little better, for example, Johnson & Johnson can also lay some soundproofing things.

You can remodel the interior to make the sound insulation, but the cost is relatively high, you can buy a noise-canceling headphones, but I still feel that it will hurt the headphones.

Install acoustic panels, honeycomb panels and other soundproof wall materials to reduce noise.

If it is the noise of the elevator machine room, it is recommended to install soundproof doors and windows indoors, such as plastic steel windows, etc.; If the house is adjacent to the elevator, it is recommended to install a soundproof wall of appropriate thickness when decorating.

There is no good solution to this, you can install soundproof cotton on your wall, and you can basically live in the noise of this elevator.

There are many causes and propagation methods of elevator noise, if it is caused by mechanical vibration or friction, the sound will not only be transmitted through the air, but also through the building itself, and this transmission is hard and far away. So you'll hear the sound. If resolved, you can complain to the property:

1. If it is the problem of elevator maintenance itself: the elevator of each property has a corresponding elevator maintenance unit, and the property will find a maintenance unit to solve it. 2. If it is an installation problem:

Property can complain to the manufacturer. 3. If it is a quality problem of the equipment (this needs to be verified by the instrument), such as the motor noise exceeds the standard (the national standard stipulates that the noise of the elevator machine room should be 80 decibels), you can also find the property to complain and negotiate with the manufacturer. 4. Or you simply take the standard of 35 decibels of residential bedroom noise stipulated by the national standard to talk to him.

The specific solution is called the property to find a way.

Depending on the specific situation, if the noise is caused by friction between the elevator operation and the guide rail, it is recommended to complain to the property and let the elevator maintenance personnel deal with it; Secondly, if it is the noise of the elevator machine room, it is recommended to install soundproof doors and windows indoors, such as plastic steel windows; Finally, if the house is adjacent to the elevator, it is recommended to install a soundproof wall of appropriate thickness when decorating.

1. Rough walls.

If the walls of the home are smooth, then the outdoor echo can be heard indoors, and the principle of echo is similar to light, and any sound can be reflected through the smooth wall. Therefore, to solve this problem, it is recommended to make the wall surface rough or choose a soundproof material when decorating.

2. The choice of doors and windows.

Usually most of the noise comes in from doors and windows, especially the gap between doors and windows and walls, so when decorating, it is best to choose double-layer hollow windows, which are glass on both sides and vacuum in the middle, and the sound insulation effect will be much better than single-layer windows.

3. The choice of fabric.

Finally, the fabric can also play a role in sound insulation, especially if the room area is large, you can choose the fabric curtains, which not only shade the light but also have the effect of sound absorption, compared with the curtain made of flannel and thick cotton, the sound insulation effect will be better. Therefore, when choosing curtains, you should also choose according to your actual situation.

Hello dear! We'll be happy to answer for you. Is it useful to do indoor soundproofing with elevator noise?

It has a certain effect, but it is not very effective. You can install an elevator silencer, in fact, depending on the situation, you have to take different solutions, you can find some companies that specialize in elevator noise reduction, and the living room and elevator shaft share a wall. If you want to carry out sound insulation, it is best to use gradient sound-absorbing cotton, cavity leakage It is a full-frequency sound-absorbing material, which can reduce low-frequency, medium-frequency, and high-frequency sound at the same time, and it is very environmentally friendly, and it can be directly in contact with the human body, and will not cause any good impact on lead seepage, and there is no dust generated.

This sound insulation effect requires a 5cm keel on the base surface of the soundproof wall, and the empty position in the middle of the keel is filled with gradient sound-absorbing cotton, and the gypsum board is sealed outside. If the landlord needs to completely eliminate the sound, he can thicken the sound insulation layer, such as using two layers of 5cm gradient sound-absorbing cotton, but it has some impact on the space. If you have any questions, you can give me feedback in time!

Let's do soundproofing. Under normal circumstances, the elevator noise experienced by residents on the top floor should be within an acceptable range. If the noise of the elevator is too loud and has interfered with the normal work and rest, the developer can be required to install sound-absorbing panels in the elevator training room, and install shock-absorbing pads under the elevator host, which can effectively reduce the noise.

Look at whether the elevator has a machine room, if there is no problem with the sound insulation of the machine room, the sound insulation of the machine room is more difficult, and according to the noise level, if it is too high, it is a problem with the debugging of the elevator itself, such as the sound of the elevator holding the gate, the sound of the elevator control cabinet can be done on the top of the cabinet door and around the corner.

Introduction to the elevatorAn elevator is a permanent transportation ambush that serves a number of specific floors in a building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15 degrees to the plumb line. There is also a stepped type, and the tread plate is mounted on the track for continuous operation, commonly known as escalator or moving walk. Stationary lifting equipment serving the specified floors.

The vertical lift has a car that runs between at least two rows of rigid hall guide rails that are vertical or have an inclination angle of less than 15°.

When you hear the noise of elevator operation at home, you must first check the noise**.

If it is the noise caused by the failure of the elevator operation or the friction of the track, please ask the elevator maintenance personnel to deal with it. If it is caused by the noise of the traction machine in the machine room or the co-wall of the elevator shaft with the owner's bedroom and living room during the design of the building, then you can only choose shock absorption treatment or install a soundproof wall. Shock-absorbing pads are installed under the elevator host, and soundproof walls around the elevator machine room can effectively reduce noise.

The excessive noise caused by the elevator failure affects the life of the residents, and the elevator company should be responsible. Residents can first complain to the property, and ask the property management to urge the elevator company to reduce the elevator noise from the mechanical aspect. If the elevator company does not maintain it in a timely manner or does not take care of it directly, it will take the property management as the fulcrum and find the neighborhood committee and the business committee to coordinate and deal with it.

Others

If the elevator is not faulty and the noise still affects life, then it is probably caused by the poor sound insulation of the building. The main reason is that when the building is designed, the elevator shaft is shared with the owner's bedroom or living room, and the noise generated by the elevator operation in the later stage is not taken into account. The elevator maintenance unit can only eliminate equipment failures, and when it comes to civil engineering problems such as structural design and weak walls of residents, it is necessary to find the developer to solve them.

However, the tug-of-war with developers is basically difficult to deal with effectively, and will only turn into a protracted tug-of-war in the end.

Sound insulation walls can be made around the elevator machine room, or sound insulation measures can be made directly on the walls shared with the elevator in the room. Through the sound insulation measures of the machine room and the sound absorption treatment of the inner wall of the elevator shaft, coupled with the protection of the sound insulation layer, a large part of the noise can be absorbed to a certain extent. If it is the resonant noise of the wall caused by the elevator work, it is difficult to deal with it through sound insulation, in this case, we can only start from the source to reduce the vibration frequency.

Summary. Hello dear, the room can hear the buzz of the elevator How to solve it as follows: Method 1:

The soundproofing layer can be made around the elevator machine room, or directly on the wall shared with the elevator in the room. Through the sound insulation measures of the machine room and the sound absorption treatment of the inner wall of the elevator shaft, coupled with the protection of the sound insulation layer, a large part of the noise can be absorbed to a certain extent. Method 2:

If the vibration reduction treatment is the resonant noise of the wall caused by the elevator work, it is difficult to deal with it through sound insulation, in this case, we can only start from the source to reduce the vibration frequency. For example, a shock-absorbing pad can be installed under the elevator host to reduce vibration and noise from the machine room.

The elevator track can also be treated with noise reduction to reduce the occurrence of noise through the operation path of the elevator.

Hello, how to solve the problem that the room can hear the buzzing of the elevator is as follows: let the infiltration method 1: make a soundproof layer around the elevator machine room to make a soundproof wall, or directly on the wall shared with the elevator in the room to do soundproofing measures.

Through the sound insulation measures of the machine room and the sound absorption treatment of the inner wall of the elevator shaft, coupled with the protection of the sound insulation layer, a large part of the noise can be absorbed to a certain extent. Method 2: Vibration reduction treatment If the wall resonant noise caused by the elevator work, it is difficult to deal with it through sound insulation, in this case, you can only start from the source to reduce the vibration frequency.

For example, a shock-absorbing pad can be installed under the elevator host to reduce vibration and noise from the machine room. The elevator track can also be treated for noise reduction, and the passage slides through the running path of the elevator to reduce the occurrence of noise.

The following is a detailed ** explanation, you can refer to it.

Elevator noise is generally dealt with by the property or developer, if the elevator noise exceeds 30 decibels at night, it belongs to the responsibility of the property and the developer, the house can find the developer during the warranty period, and do not find the property to pay for the warranty period.

The base of the elevator traction machine is installed above the split metal damping platform to reduce the transmission efficiency of the rigid connection of vibration and sound waves. (Main Measures).

2.The elevator machine room is designed for floating structures on the ground, and materials such as steel bars, concrete, and sound insulation pads are laid layer by layer.

3.Elevator guide rail vibration reduction, hoistway sound insulation and other means, according to the on-site noise analysis to determine whether it needs to be implemented.

First of all, it is necessary to find the "sound source", the reasons for the elevator noise are those, the elevator noise is low-frequency noise pollution, which is different from the general noise control (the general noise is the air as the sound transmission medium, and the noise of the elevator is mainly manifested as low and medium frequency vibration, and its main propagation path is vibration-type solid sound). Therefore, the conventional method of sound insulation board, sound absorbing cotton or sound insulation wall can only reduce the noise with air as the sound transmission medium, and has little effect on the reduction of low-frequency noise transmission of the elevator. ）

Most of the users and owners who are troubled by elevator noise "because the main load-bearing beam wall of the elevator in the machine room is designed with the residents to share a common wall, or the main wall of the owner's house is connected with the main load-bearing beam wall of the machine room, and is rigidly connected with the reinforced concrete of the building, which becomes the main propagation of the elevator noise 'sound bridge', resulting in noise."

It is understood that there is no department in China to accept elevator noise complaints, and residents can apply to the Environmental Institute of the Chinese Center for Disease Control and Prevention to make a "pollution" assessment and identification. After getting the report, you can negotiate with the real estate developer or property company to solve it.

Partly refer to Mr. Elevator.

Answer: Elevator noise generally has to be dealt with by the property or developer, if the elevator noise exceeds 30 decibels at night, it belongs to the responsibility of the property and the developer, the house can find the developer during the warranty period, and do not look for the property during the warranty period.

Formation of elevator noise.

1. There is a rigid connection between the load-bearing wall of the elevator machine room and the wall of the owner's house;

2. Sound transmission of elevator shaft structure.

The elevator is driven by manganese phosphate coated wire rope bearing and traction, which is widely used in high-rise buildings. The noise of the elevator is due to the large vibration of the equipment parts, and the cause of the vibration is the wear and tear of the parts. Lubrication and maintenance of the elevator can reduce noise, and the parts with serious wear and tear should be scrapped and replaced in time.

The effective elevator noise control measure usually adopted is to dampen the vibration of the elevator group

1. The power distribution cabinet adopts a low excitation frequency foundation, and the incoming and outgoing wires are treated with soft contact, and the sound bridge formed by the rigid link between the building and the floor is disconnected, and the low-frequency noise of electromagnetic radiation is cut off from the root;

2. Install professional elevator shock absorbers, according to the principle of vibration reduction, vibration cancellation, barrier vibration reduction and sound insulation, our company has developed a split metal vibration damping platform with the advantages of high vibration isolation rate, small size, light weight, convenient installation and maintenance, and elimination of potential safety hazards, which is widely used in various types of elevator noise reduction projects.

3. The sound transmission of the hoistway structure is treated with vibration reduction, that is, the wire rope opening under the load-bearing I-beam of the traction machine is soundproofed.
