High rise residences, what are the quietest floors? High rise residences, what are the quietest floo

High-rise residential. What are the quietest floors?

Modern people live in a noisy city, who wants to be able to enjoy a moment of tranquility after returning home, in the reinforced concrete jungle, which layer can make us live comfortably and quietly?

Nowadays, there are many high-rise residences, and everyone knows that the propagation of sound is directly related to distance. So the farther away the floor we live on from the sound source, the quieter the environment we live in. From this point of view, we should be able to solve the noise problem if we live on the top floor or on the upper floor.

In general, high-rise buildings in cities.

In fact, the higher the floor, the louder the noise will be, generally the noise of the 1-5 floors is relatively small, the 11 floors are medium, and the 24 floors are relatively large, so if you want to buy a house in the bustling city center, it is recommended to buy 1-5 low floors. The noise above the 24th floor or higher will gradually decrease, because the higher the overlook, the larger the overlook range, the distant road noise and construction noise can be transmitted, and the relative noise sources will increase; The lower the floor, some noise sources will be covered than other buildings, and the noise will be smaller. Noise pollution, of course.

The degree of the depends on the specific environment, if the noise ** only one road, the situation will be different, often 1 floor will be smaller, 11 floors will be larger, and then the upper floor will gradually become smaller, this is because the higher the floor, the longer the distance of sound transmission, so the attenuation becomes smaller, and other factors are discharged.

Why aren't the noisy floors on the top floor? Everyone also knows that the penetration of sound is limited, and if it encounters an obstruction, it will be **. But the top floor is often higher than the surrounding floors, arguably the emptiest place at the top.

This allows the top floor to pick up noise from all directions, so it's a bit noisier. Although there will be attenuation of the sound on the top floor, the overall attenuation is not large. And the most unbearable thing we usually bear is actually some small noises that are irregular for a long time, and it is not completely because of the noise that we must feel uncomfortable.

Therefore, the top floor is actually not that quiet.

The upper middle floor is actually good, because in most of the community, the buildings around the upper middle floor can help the first noise of this floor, if we can choose the building in the middle of the community, then the noise will be smaller, as long as the community is quiet enough, the upper middle floor will not have noise from outside the community.

Sometimes the lower floors may be quieter than the upper floors. Speaking of which, many people will definitely say that it is impossible. But it's also true, and why?

Because now whether it is road greening, community greening is doing better. These green vegetation can block out the noise on the ground floor, so that the noise in the room is attenuated, in contrast, the noise of the higher floors can be directly transmitted without blocking, which is why the ground floor is quieter than the upper floors.

Above the 15th floor, it is very quiet, and it will not be disturbed by the sound of children playing and chatting downstairs, and it depends on whether the neighbors have children, whether they have pets, if there are these problems, several floors are useless.

Generally, 20 floors up, the sound is much quieter, and there is basically no sound after closing the window. Therefore, I think if the area around the house is noisy, it is best to choose a house with more than 15 floors. For the atrium, you can lower it appropriately.

High-rise selection 14-18 is not high, not low, the least noise, look at the beautiful scenery in the community, the comfort is good, too high can only look at the high-rise buildings in the distance to see the poor comfort in the community.

What are the quietest floors of a high-rise building? Many people get it wrong, tell your family, don't ignore it.

In fact, the top floor of high-rise residential buildings is the quietest, because the top floor is the top of the elevator, and the noise of the elevator running is relatively small, and it is quieter than other floors.

Many people prefer to live in high-rise buildings.

, not only because they stand tall and see far, but also because they are far away from the road and are less affected by traffic noise such as traffic flows. In fact, experts from the Environmental Protection Agency found that the decibel noise of high-rise buildings was "small at both ends and large in the middle", with noise from floors 5 to 24 and more than 30 becoming quiet. High-rise and low-rise buildings suffer from different forms of noise pollution.

For the lower layer, its noise source is represented by vibration and sound.

For high-rise residents, the impact of vibrations is constantly diminished, but sound travels in the form of sound waves. Noise is noticeable when the height of a floor is an integer multiple of the wavelength of the noise wave. There are no buildings around the tall building, and the tall building is completely exposed to the three-dimensional propagation of sound waves, so it is very noisy.

However, as the noise begins to attenuate at a certain height, residents on the upper floors are less affected. Noise propagates upwards, high-rise residential.

The noise is between 30 and 70 meters.

The lower the floor, the lower the noise. In addition to green belts and street trees.

In addition to reducing noise, the lower floors only receive noise over short distances. The higher the floor, the wider the range of noise received, and long-distance traffic noise can be transmitted to the upper floors. Generally speaking, above the 5th floor, the noise decibel will increase as the floor increases.

When the floor is higher, the noise decreases again. In general, in high-rise buildings, the noise from the 5th to the 24th floor rises more from the 11th to the 22nd floor, and the more than 30 floors are quiet. If it is a 26-storey building, the noise may reach 20-22 floors.

Road greening and community greening are both well done. These greens block out the noise from the ground floor, thus reducing indoor noise. In contrast, noise from slightly higher floors can be transmitted directly without shielding.

There is no need for buyers to dwell too much on the silence of the floor. Because noise attenuation is not noticeable over a range of 200 meters, and noise at the bottom cannot be attenuated to the top decibels, we should choose more floors away from the city center, main roads, and the edge of the neighborhood to really reduce the noise.

Between layers 10 and 15. Because such a floor is not very high, nor is it very low, the higher the floor, the worse the sound protection effect of the building.

Living on the 6th and 7th floors is relatively quiet, because this level is relatively high from the ground, whether it is above or below, there will be no noise impact, so it is quiet.

The 15th floor of a high-rise residential building is the quietest, because the height of the 15th floor is a medium height, and it will generally be far away from the city scenic area, and there will not be too much noise.

Problem description: Because there are elderly people in the family who like to be quiet, I don't know if it is quiet to live below the 10th floor or above the 10th floor.

Analysis: There are two phenomena in the current commercial housing market: the first is that the building is higher and higher, and the second is that the higher the floor, the more expensive it is sold, and only in the highest one or two floors will there be a ** fall. What exactly is the ideal height for a dwelling? Is the top rightly expensive?

Gu Mengchao, a professor-level senior architect of the China Architectural Association, believes that high-rise residential buildings are the product of the development of specific national conditions such as large population and low land resources. The most ideal house for people is to be close to nature and close to the ground, so the bungalow is in fact.

The best place to live. Each floor of the building has its own specific advantages, but also faces certain problems, and the choice of floor when buying a house should be determined according to different needs.

1st floor and 2nd floor: From the point of view of convenience, the lower floor is naturally preferred. The elderly have a high travel rate, live on the lower floors and are convenient to move around, and the elevator is not affected if it breaks.

There are also many residential projects with a garden on the first floor, which is very suitable for middle-aged and elderly people. From the perspective of noise, the noise of the lower floors is much less than that of the upper floors that directly receive sound waves due to the filtering of obstacles and green belts. In addition, for the elderly, living in a high-rise may also face physical problems such as heart discomfort.

Middle floor: From the perspective of market sales, the middle and upper floors of a building are the most popular, and the speed and average level are better than other levels. This is mainly because the middle of the building is relatively eclectic, with the advantages of high-rise and low-rise buildings, convenience and landscape are good, and at the same time the needs of people of different ages can be taken care of, and the needs of all members of the family can be met.

High-rise + super high-rise: Ten years ago, residential buildings rarely exceeded 20 floors, and Chong Danfeng's new residential projects now have 20 or 30 storey towers abounding, gradually becoming the mainstream. Although the higher the residential building is built higher and higher, it is a last resort with limited land resources, but because the high-rise buildings have higher requirements for the building, and the difficulty of earthquake and water pressure design increases, the development cost is relatively higher, which is why the higher the floor, the more expensive.

Even so, high-rise housing meets the needs of young people: a wide view, fresh air and privacy. The popular terrace on the top floor is also an important factor in attracting young people.

However, after all, the building is not as good as the courtyard house, and no matter how many floors you live in, there are specific troubles. If you live on a low floor, the stairs at the door of the house are the common passage of the whole building, and it is difficult to ensure quiet and hygiene; It's also a headache for damp and unscrupulous high-rise residents to throw things down. If you live in a high-rise building, the inconvenience caused by a broken elevator can be imagined; Although the level of architectural design and engineering is advanced today, high-rise residents are still prone to weakness in the event of heavy rain or **; Other experts reported that living in high-rise buildings can easily lead to children's lack of activity and closed personalities, which has a certain impact on their physical and mental development.

From the perspective of comfort, the more floors of a community residential building, the higher the floor area ratio, the lower the level of per capita occupancy of public facilities, and a certain quality of life will inevitably be sacrificed.

The best floor option for high-rise residential buildings is 15-storey high-rise residential buildings, and 5-7 floors are the best. In fact, each layer has its own benefits.

Ground floor: The advantage is that it is suitable for families with elderly people, easy to access, and it is better if there is a garden. But the disadvantage is that the lighting and ventilation are not good, and the humidity is heavy, especially in the south. In addition, the road is on the road, and the cars are noisy and noisy.

2nd to 5th floors: The advantage is that the temperature is lower than above in summer, and it is easy to escape in case of fire. The disadvantage is that the view is not good, the room is dark, the light is turned on for a long time, and the noise is on the high side.

6th to 7th floors: The advantage is that there is a view to see, but the view is still not so good, so you don't have to worry about the humidity. The downside is that the light is still insufficient.

8th to 11th floors: The advantage is that the light, air, etc. are less than the top, more than the bottom, if the power is out, the stairs are also within the acceptable range, this height is also more suitable.

12 to above: The advantage is that it is the best floor in the eyes of experts, the lighting of the floor is very good, the sunshine hours are long, and the view is also very wide. The impact of noise is also less.

The disadvantage is that it is inconvenient to travel, such as water supply and elevators cannot be normal after a water outage or power outage.
