There is too much noise in the elevator upstairs, which affects people's rest. What should I do?

When buying a house, you need to choose the floor carefully, because some floors will be disturbed by external noise, such as elevator noise. If the elevator in your house is noisy, how to solve it? What are the specific methods? Let's get to know each other.

Generally speaking, the house on the top floor is closest to the elevator machine room, so I feel that the elevator noise is louder than the houses on other floors. If the owner thinks that the elevator noise has affected the normal work and life in the house, he can apply for the property or the developer to take the lead and ask a third-party organization to conduct noise assessment to see if it exceeds the national standard. If it exceeds the national standard, he can complain on the grounds that the developer's building is not up to standard.

Meanwhile, the elevator noise solutions are as follows:

1, sound insulation and sound absorption in the machine room

It can be improved by sound insulation of the wall of the computer room. Here, it is required that the sound insulation of the wall should reach more than 50 decibels, and the sound absorption treatment device should be added inside the computer room.

Step 2 choose the elevator

Choose elevators with noise value as the main technical index in strict accordance with national standards. Here is a reference value for everyone. The specified elevator noise standard is 80dB(A), and the elevator noise with excellent technical quality can reach 70dB(A). Products with noise values specified in the standard can not only reduce the difficulty of post-processing, but also reduce the cost for developers and builders.

3. Sound insulation and sound absorption treatment of elevator car

Noise removal in the car should not be underestimated, and a layer of sound insulation and absorption should be made between the roof, the wall and the ground. However, it should be noted that the materials must meet the requirements of environmental protection standards to avoid secondary pollution to the environment. It will have a great silencing effect on the airflow sound generated by high-speed operation.

4. Vibration isolation treatment of traction machine

Sound transmission by structural vibration is the main way of noise transmission of traction machine. In order not to be affected by noise, a powerful solution is to adopt double-layer vibration isolation and do a good job of vibration isolation of traction machine.

5. Wind noise control

There is a temperature difference between the elevator shaft and the outdoor. Vents can be installed in the elevator shaft to reduce howling during operation, and sound absorption and sound insulation devices can be installed in the elevator lobby and car. Are very good methods.

Generally speaking, according to the above, the problem of elevator noise can be easily solved. In daily life, the interference caused by noise will affect work and rest, which needs our attention.
