Can the noise of the elevator be detected, and which department to find for the elevator noise detec

OK. Elevator noise measurement methods and limits.

1. The quality standards of the elevator itself mainly include "Elevator Technical Conditions", "Elevator Manufacturing and Installation Safety Specifications", etc.; It is stipulated that the sound of the main engine room shall not be higher than 80 decibels, and the sound of the car shall not be higher than 55 decibels.

2. The architectural standards, mainly including the "Residential Design Code" and "Civil Building Design Sound Insulation Code", stipulate that it shall not be higher than 50 decibels during the day and 40 decibels at night;

3. Environmental protection standards, mainly including "Acoustic Environment Quality Standards", etc. It should not be higher than 40 decibels during the day and 30 decibels at night.

2. Regulatory standards:

1. GB22337-2008 social living environment noise emission standard;

2. GB 3096-2008 "Acoustic Environment Quality Standard".

3. Elevator noise limit:

Note: The "average noise value in the machine room" of the elevator without machine room is the average noise value measured at a specified distance of 1 meter from the traction machine.

4. Measuring instruments: Type 2 integrated average sound level meter or environmental noise automatic monitor, type 1 sound level meter should be used to measure noise below 35db, and when spectral analysis of noise is required, the performance of the instrument should meet the requirements of GB T3241 for filters. And check it regularly.

Use an acoustic calibrator to calibrate before and after (the deviation of the indicated value must not be greater than dB), otherwise the measurement will be invalid. The acoustic calibrator should meet the requirements of a Class 1 or Level 2 acoustic calibrator.

5. Elevator noise detection index: machine room noise, elevator car noise, elevator door opening and closing noise and indoor key point noise of the elevator during elevator operation.

6. Elevator noise source: low-frequency vibration sound caused by operation; Noise pollution such as friction sound and air flow generated during operation.

7. Elevators are classified into two categories of noise sources according to the transmission mode.

1. Structural sound transmission of the machine room: sent by the elevator host and the control cabinet of the machine room, the main load-bearing beam main wall in the elevator machine room and the main wall in the owner's house are a public wall or are rigid structural conjoined bodies, so the elevator noise mainly spreads "sound bridge", and the low-frequency vibration and noise of the elevator during high-speed operation and parking are transmitted to the living room through the sound bridge. At present, the most common type of indoor elevator noise pollution case, the top floor or sub-top floor residents are affected by the noise, and the other floors are not greatly affected, and the noise is reduced to below the comfortable sound environment by adding a low-frequency damping composite damping device to reduce the vibration transmission rate.

2. Shaft structural sound transmission: when the elevator is running, the noise problem caused by the friction of the car and the counterweight main rail transmitted to the shaft structure. The main rail of the elevator is fixed on both sides of the door and connected with the wall, and the friction and vibration when the car guide rail is taxied and stopped will be connected with the wall through the fixed guide rail to form a "sound bridge" and transmitted to the resident's room.

You can first find the property to report for repair, and the elevator maintenance fee you pay every month is used when the elevator has a problem.

The main noise is generated by the rotation of the motor or the lubrication is not in place, and it will be better to install some sound insulation materials, in fact, it is good to listen to it. As long as the elevator sound is not excessive! The operating noise of the elevator is regulated, if you feel that the noise is too loud, you can first find the local technical supervision department to do a test, if it exceeds the standard, you can find the property to negotiate or find the elevator company to solve, and then can not solve the problem to find the court to solve!

It is recommended that you choose Beijing Indoor Environmental Pollution Detection Technology Center for testing, and we will issue an effective test report for you to solve your troubles.

Poor installation can be measured with a decibel meter.

Elevator noise detection can be detected by the local environmental protection department.

Elevator noise detection was originally a very simple technical operation. However, due to the fact that the detection point is often affected by other different types of noise sources (such as traffic noise, construction site noise, vibration noise of other equipment in the building, social life environment noise, etc.), the on-site detection is relatively complicated.

And because the inspection often fails to grasp the key elements of the core, it leads to technical errors. As reflected by the above-mentioned Nanning residents, the indoor 24-hour elevator noise monitoring, because within 24 hours of monitoring, the actual operation time of the elevator in the newly occupied community may only be less than 2 3 hours.

Who is responsible for indoor elevator noise?

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.

The vibration and noise generated by the operation of the elevator will be diffused to the surrounding rooms in the form of solid sound transmission through the walls and floors of the building.

Elevator noise is mainly generated by the following sound sources:

First of all, the low-frequency vibration and noise caused by the operation of the traction machine propagate along the main load-bearing wall of the structure, causing the wall floor to disturb and resonate. This kind of noise mainly affects the residents of the top or sub-top floors, and other floors are not greatly affected, and the noise can be reduced to below the comfortable sound environment by adding a low-frequency damping composite damping device to reduce the vibration transmission rate.

Secondly, the friction between the guide shoe (guide wheel) and the guide rail, and the friction between each rotating part and the wire rope when the car and the counterweight run up and down, produce noise transmitted to the adjacent wall and affect the household. This type of noise is mainly affected by the residents of the middle floor, and the noise source or partition noise propagation can be reduced by using rolling guide shoes, changing the way the rail bracket is fixed, etc.

In addition, the air flow noise generated by the high-speed operation of the car is transmitted to the adjacent wall and affects the occupants. This kind of noise mainly appears in high-speed elevators, and the main solutions are to improve the ventilation design of the hoistway and reduce the running speed of the elevator.

The noise of the elevator is definitely different, some are the sound of the motor running at night, and some are the sound of frustration.

Elevator noise refers to the unwanted sound generated by humans in the design, installation and use of elevators. Elevator noise is mainly manifested as low and medium frequency vibration, and the propagation mode of elevator noise is mainly based on vibration type, which is transmitted through solids. Shenzhen Baoze environmental protection for you to answer, thank you for adopting.

Elevator noise is mainly generated by the following three sound sources:

Firstly, the low-frequency vibration sound energy caused by the driving operation of the traction machine and the operation of the car and the counterweight in the main engine room propagates along the main load-bearing wall of the structure, causing the disturbance of the wall floor to produce resonance.

Secondly, the friction of the traction equipment promotes the elevator car to run up and down, and the friction sound is generated between the traction wheel and the traction rope in the process of high-speed operation of the elevator, and sometimes it is also transmitted to the car by the wire rope, and then transmitted to the guide rail, transmitted to the adjacent wall, and affects the residents;

In addition, the friction between the guide shoe (guide wheel) and the guide rail, the friction between the rotating parts and the traction rope, and the air flow generated by the high-speed operation of the car will be transmitted to the guide rail and the adjacent wall when the traction equipment and guide rail are running up and down, affecting the residents.

The solution to elevator noise: is to isolate the propagation of sound through the targeted design of the special low-frequency vibration damping layer for elevator noise, and at present, there is a special elevator noise control company in China, which is specially designed for the low-frequency transmission principle of elevator noise to digest all the vibration and noise pollution emitted by the elevator.

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.

1. Elevator noise**

Elevator noise mainly includes mechanical noise, air noise, friction noise, electromagnetic noise, etc., including electromagnetic and mechanical noise of the main engine operation, mechanical noise of the brake, friction noise between the cable and the car, and wind pressure noise of the hoistway. Elevator noise mainly belongs to medium and low frequency noise, which is transmitted to the building through the steel frame structure and then transmitted to the space in the building.

Second, the elevator noise control plan

1.For the friction noise and gap noise in the elevator track, the three-way elastic support frame is used to replace the original fixed support to reduce vibration and avoid resonance. For the problem of wind pressure in the hoistway, it is recommended to set up a pressure relief port on the floor without about 4 floors, and install a muffler in front of the cable.

2.Elevator machine room noise control:

In view of the vibration noise of the elevator host and the noise of the brake, which are mainly vibration type noise, the elevator low-frequency shock absorber is used to realize full-band noise reduction and isolate the propagation of elevator noise. Vibration damping pads are installed under the motor cabinet in the machine room to prevent high-frequency sound from penetrating the wall.

3.Other measures: cabinets, contact switches and other parts can be separated from the ground with rubber damping pads.

After the implementation of vibration reduction measures, the elevator can meet the noise standard of Class 1 mixed area of the "Urban Environmental Noise Standard", which is not higher than 40 decibels during the day and 30 decibels at night.

The control of elevator noise can start from the following aspects:

1. The sound insulation of the noise of the computer room includes the construction of the computer room, the shock absorption and sound insulation measures of the computer room, and the sound absorption treatment of the computer room, etc., so as to reduce vibration and noise from the computer room.

2. The sound insulation of the elevator shaft includes the sound absorption treatment of the inner wall of the elevator shaft, the ventilation design of the elevator, and the noise reduction treatment of the elevator track. The occurrence of noise is reduced through the operation path of the elevator.

3. The sound insulation of the elevator door should pay attention to the installation of the elevator door and the lubrication of the track.

4. The developer of building sound insulation design should take into account the problem of noise when designing the building structure, keep the user's common space away from the elevator shaft from the design, and take shock and noise reduction measures between the user's room and the elevator shaft. The type of elevator is selected according to the actual use.

5. If the room and the elevator are already in an adjacent state, then we should pay more attention to the layout of the indoor room, and try to avoid the situation that the bedroom is separated by a wall from the elevator shaft.

Article 61 of the Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution stipulates that units and individuals who are harmed by environmental noise pollution have the right to require the perpetrator to eliminate the harm; where losses are caused, compensation shall be made in accordance with law.

Disputes over liability and the amount of compensation may be mediated and handled by the competent department of ecology and environment or other supervision and management departments and institutions for the prevention and control of environmental noise pollution at the request of the parties; If mediation fails, the parties may file a lawsuit in the people's court. The parties may also file a lawsuit directly with the people's court.

You can go to the EPA to file a complaint.

Question: Can I ask the developer to refund the principal of the house I bought in 2017?

Question: How much will the elevator go when it is silenced?

Question: Our house is an elevator apartment with 7o years of property rights, and they can compensate for the loss after being a homestay for several years, which has affected the business.

This is something that can be claimed.

Question: What kind of compensation?

Question: Should the house handed over in 2017 be invested in the developer or the property company?

Now the elevator is within the scope of property management.

The elevator noise is large to deal with the original elevator host, and the foundation of the distribution cabinet is rigidly connected with the reinforced concrete of the building, which becomes the main propagation "sound bridge" of elevator noise. The original foundation is transformed into a composite broadband K-value (neck coefficient) vibration and noise reduction foundation to isolate the propagation path of low-frequency noise.

According to the analysis of elevator noise types and the main propagation pathways of vibration, elevator noise control focuses on the combination of shock absorption and sound insulation means.

1.The split metal elevator damping platform with strong pertinence is selected to reduce the vibration sound wave transmission efficiency of the traction machine.

2.The contact port of the wire of the control cabinet is wrapped with a rubber soft strip to disconnect the rigid connection of the equipment.

3.Install the elevator guide rail shock absorber to reduce the friction structure of the guide rail and transmit the sound.

Answer: Under normal circumstances, the elevator noise felt 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 machine room and shock absorbing pads under the elevator host, which can effectively reduce the noise.

In addition, do a good job of soundproofing the door, due to the noise of the elevator on the top floor, it is really annoying, you can use a soundproof door, or make a soundproof door, which will have some effect.

Finally, if the noise is caused by the friction between the elevator operation and the guide rail, complain to the property and call the elevator maintenance unit to reduce the noise.
