Elevator noise has a certain impact on children's health and growth!

Mr. elevator answers:

The harm of noise to human body originated from the appeal of the World Health Organization. After investigating noise pollution cases all over the world, they believe that noise pollution has become an environmental factor affecting human health after air pollution. It can affect people's hearing, and also lead to hypertension, heart disease, memory decline, inattention and other mental syndromes. They actively call on all countries to take effective measures to control the impact. Elevator noise is mainly caused by the running vibration of elevator equipment, because the human body is more sensitive to low-frequency vibration. Especially for the noise sensitive groups, there will be obvious interference and discomfort when they are indoors. At the same time, the elevator noise will also have a negative impact on the sense, sleep, mood and other aspects of the residents. If they are in the environment disturbed by noise for a long time, they will certainly have a certain impact on people's health.

From the situation you reflected: children do feel the existence of elevator noise in their daily study and life, and they are disgusted with this sound, which also causes the fact that they are distracted in their study. In view of the fact that the child is still in the development stage, there may be some objective situations in listening, such as not yet sound and mature, not fully focused, easily distracted, etc. in order to ensure the child's health and learning focus, there is no interference. We sincerely suggest that effective measures should be taken to reduce noise in elevator machine room to solve the interference of elevator vibration and noise. According to your current situation and the current housing price evaluation of Guangzhou Pearl River New Town, the overall management cost is not large, whether it is individual investment or looking for development company to invest in the elevator management. Compared with other options such as whether to change rooms or not, the best way is to implement noise reduction treatment for elevator machine room. (welcome to the WeChat public number of "elevator noise control", which is the original column of "the elevator noise prevention, I am the expert - I do not know you ask").

Customer question 2:

Am I too sensitive to elevator noise? Can elevator noise be solved?

background

Miss Huang's family lives in Qianjiang New City, Hangzhou city. Due to the lack of attention during the house selection, she accidentally chose the house type adjacent to the elevator shaft on the top floor. After the new house was moved in, it was affected by the elevator noise. Although other members of her family could hear the elevator noise, she was distressed that other people thought that this small noise had no effect, including his husband, who always advised her: "this small noise is not relevant Don't worry, don't get tangled up. " However, she often stayed at home and thought the elevator noise was very annoying. Every time she heard the "buzzing" sound, she felt very uncomfortable. So I have been searching for solutions on the Internet and calling to ask: am I too sensitive to elevator noise? Can we solve it?

Personal sensitivity to elevator noise is different, elevator noise can be completely solved!

Mr. elevator answers:

From the elevator noise reduction cases of Shenzhen and Japan company in the past ten years, the sensitivity of different people to sound is indeed different, so the elevator noise you reflect is a normal phenomenon, which does not mean that you are too sensitive to sound. Because elevator noise belongs to low-frequency vibration noise, and its main frequency is between 125-500hz. If you simply use the equivalent a sound level to evaluate, you will find that the sound level of this kind of sound is not high, but this does not mean that the vibration sound itself does not exist or has no effect at all. When you use the measurement method of octave band sound pressure level again to detect the indoor environment under the running and stopping state of the elevator, you will find that the above-mentioned frequency band sound difference value (running and stopping of the elevator) in the room adjacent to the elevator will reach 10 dB or even 20 dB. However, because the overall A-level of this sound is not very high, some people who are not sensitive to the sound will find that although they can hear it, they do not have too much worry.

From the case analysis of nearly 50000 noise reduction projects of elevators in Shenzhen and Japan, it can be seen that the affected people choose to stand, sit and lie down, and their perception of elevator noise will be different under different conditions. In addition, from the practice research of Shenzhen and Japan company in recent years, it is found that the feeling degree of people in indoor environment is not the same. From the research and test cases of Shenzhen and Japan company, it is found that many people who have just entered the room from the outside do not feel the elevator noise obviously in the first 15-30 minutes. However, after a period of time in the room, the body is completely relaxed. After about 2 hours, the interference on the elevator noise is significantly increased.

In view of the above reasons, it is recommended that you choose a professional noise testing company to test the indoor elevator noise, and first confirm how much the impact of elevator operation on the indoor? Does the indoor noise during elevator operation affect the current national standard? Then, according to the test data to make the corresponding choice, decide whether to reduce the noise of the elevator. (welcome to the WeChat public number of "elevator noise control", which is the original column of "the elevator noise prevention, I am the expert - I do not know you ask").

If the detected elevator noise does not exceed the current national standard, considering that other members of your family are not sensitive to elevator noise and have no annoyance, you can also apply the "sound masking effect". Improve the impact of elevator noise on you by adding a sound measure indoors, such as adding background music indoors, setting a small rockery with running water sound, goldfish tank, or installing a large air volume air conditioner indoors. From the application experience of many years in Shenzhen and Japan, when adopting the above measures, because the sound level of the equipment is higher than that of the elevator, the trapped people often hear more from the air purification equipment when they are indoors, so the impact of the elevator noise will be alleviated to a certain extent.
