Does floor noise affect the 6th floor?

Generally speaking, the noisy high-rise houses with 5-24 floors are noisy, and the 8-11 floors are the so-called dust layer in environmental science. Buy 5 floors well.

In the area where the road is concentrated, there are five or six storey multi-storey buildings around, and there is a small high-rise building with 11 floors in the middle, so its "noise layer" is on the 7-11 floors, and the higher the floor, the louder the noise.

Layers 8-11 are the so-called ash layer in environmental science.

The dust and harmful substances in the air have a process of staying at this altitude, in fact.

Due to the "canyon effect."

(the "canyon effect" refers to the surrounding public transport arteries, factories, and high-rise residential buildings) is that the dusty air flow does not move smoothly under the influence of street wind, but "hovers" up and down a certain area between high-rise buildings.

The fourth and fifth floors have much less harmful substances because they start to sink or dissipate horizontally.

Extended Materials. The impact and harm of noise on people are directly related to the intensity of noise. In buildings, the measures taken to reduce noise are mainly sound insulation and sound absorption.

Sound insulation is the isolation of sound sources to prevent noise from being transmitted indoors. Planting trees on both sides of the road can insulate the houses on both sides.

In the building, the sandwich structure made by separating the multi-layer dense material with porous material will also have a good sound insulation effect. In order to eliminate noise, the commonly used sound-absorbing materials are mainly porous sound-absorbing materials, such as glass wool.

Mineral wool, expanded perlite, perforated sound-absorbing panels, etc. The sound absorption performance of a material is determined by its roughness, flexibility, porosity and other factors.

In addition, the lawn and trees around the building are also good sound-absorbing materials, so we plant flowers and trees, which not only beautifies the environment in which we live and learn, but also prevents noise pollution to the environment.

Chinese psychology believes that in addition to considering human factors, the control of noise environment must also take into account economic and technical feasibility. Adequate noise control must consider the entire system composed of the noise source, the sound transmission pathway, and the recipient. Measures to control noise can be aimed at any of the three or any of the above.

There should not be much difference between the impact of floor noise on the sixth floor and the impact on the first floor! Because sound is in a straight line!

I don't know! You can ask someone.

The 4th floor is less noisy than the 6th floor because the noise is absorbed during the propagation process.

Generally speaking, the fourth floor is closer to the trees below, and it is they that block out a large part of the noise. In particular, the tall trees have a more obvious effect on noise suppression. So the sixth floor is a little louder than the fourth floor.

At the same time, it also shows that when buying a house and choosing a floor, it is not that the lower the floor, the louder the noise. If the height and density of the green vegetation are good enough, the noise of the lower floors will be even less.

Introduction:

The normative use of noise is noise, and from a physiological point of view, any sound that interferes with people's rest, study and work, as well as the sound that people want to hear, that is, unwanted sound, is collectively referred to as noise. Noise pollution occurs when noise has an adverse effect on people and the surrounding environment.

In physics, noise refers to all irregular signals (not necessarily sound), such as electromagnetic noise, thermal noise, radio transmission noise, laser noise, fiber optic communication noise, camera image noise, etc.

According to the results of related experiments, the noise of the middle floor of the high-rise residential building adjacent to the street is the largest.

According to the results of related experiments, the noise of the middle floor of the high-rise residential building adjacent to the street is the largest.

The floor height that car exhaust can reach is: 1. No matter what kind of gas pollution, the heaviest is on the 9th to 11th floor, because this height is mostly about 30 meters, which is exactly the suspension height of particulate suspended solids. 2. The action of the street wind makes the airflow containing dust "hover" up and down in a certain interval between high-rise buildings.

Pollutants near the ground rise to a certain height with the airflow and then dissipate downward, that is, between the 9th and 11th floors.

Have a great day.

Home is 100 meters away from the road, will car exhaust pollute?

Not less than 200 meters is more appropriate.

The ninth-story house at the west end of Building 20 of Fuzhou Shoukai Guoshi Mansion, can car exhaust pollute the first few floors of the west end of Building 20 of Fuzhou Shoukai Guoshi Mansion, better?

Eleven or twelve floors are better.

The ninth-story house at the west end of Building 20 of Fuzhou's first opening of Guoshi Mansion, can car exhaust be seriously polluted, but there is a certain amount of pollution.

Hello dear, under normal circumstances, the noise of living on the 26th floor will not affect the fourth floor, which is far away. If there is really noise, the general noise treatment method is to install sound insulation cotton or protection, but it feels unrealistic to do such noise reduction treatment measures in a huge community, first of all, the cost is very high, and then the overall appearance should be considered, as well as ventilation, fire prevention, etc., which is unrealistic here. Planting greening will have some sound insulation effect, but it will not be particularly obvious, and this cycle is longer than the burning wheel cavity, and when the shrubs grow taller and the trees are luxuriant, it will take several years, and the cost is not low.

The most practical leather shirt is to solve the noise problem in the household's home, you can replace the doors and windows, choose the doors and windows with better sound insulation effect, and the sound insulation effect in the house should be better. Dear, remember to wear a mask when you go out, pay attention to protection, protect yourself, here the teacher wishes you a happy play Kirino Ha<>

Summary. Dear, the noise of living on the 26th floor generally does not affect the fourth floor, and the noise generally only affects the upper and lower floors, unless it is the noise of the 26th floor, so that no matter which floor will be affected.

If I live on the 26th floor, will the noise caused by the children jumping in the house affect the residents living on the 4th floor?

Dear, living on the 26th floor of the noise generally does not affect the fourth floor of the first cover, the noise of staring generally only affects the upper and lower floors, except for the noise of the 26th floor, so that no matter which floor will be affected.

Dear, the noise of children jumping on the 26th floor does not affect the residents of the fourth floor at all. We all know that sound travels upwards, so some of the higher floors are noisier. Generally speaking, the height of high-rise dwellings is between 30 and 70 meters, which is relatively noisy.

The noise of the lower floors will be relatively small, because the branches conceal the green belt, and the street trees can also reduce the noise, and because the low floors only receive noise at close range, and the higher the floor, the wider the range of received noise, and the long-distance traffic noise can be transmitted to the high-rise.
