Modern people live in a noisy city, and everyone wants to enjoy a moment of peace when they go home. In the jungle of reinforced concrete, which floor can make us live comfortably and quietly?
There are many high-rise houses now, and everyone knows that the spread of sound is directly related to distance. So the farther away from the sound source, the quieter the environment we live in. From this point of view, living on the top floor or higher floor should solve the noise problem. But the fact is not so simple. Focusing only on high floors may bring us more noise.
Generally speaking, there are many high-rise buildings. In fact, the higher the floor, the louder the noise. Generally, the noise on the 1-5 floor is relatively low, the 1 1 floor is of medium level, and the 24th floor is relatively large. So if you want to buy a house in the bustling city center, it is recommended to buy the 1-5 floor. The noise of floors above 24 or higher will gradually decrease, because the higher the bird's-eye height, the greater the distance that road noise and building noise can transmit, and the relative noise sources will also increase; The lower the floor, some noise sources will be covered than other buildings, and the noise will be less. At this time, the middle floor is the most suitable for buying a house. Of course, the degree of noise pollution depends on the specific environment. If there is only one road as the noise source, the situation will be different. Often the floor of 1 will be smaller, and the floor of 1 1 will be larger, and then the floors above will gradually become smaller. This is because the higher the floor, the longer the sound propagation distance, so the attenuation will be smaller, excluding other factors. At this time, you need to buy a house, whether it is low-rise or high-rise.
Why is the floor with low noise not on the top floor? As we all know, the penetrating power of sound is limited, and it will bounce back when encountering obstacles. But the top floor is often higher than the surrounding floors, which can be said to be the most empty place on the top floor. In this way, the top floor can receive noise from all directions, so it will be noisy. Although the treble on the top floor will be attenuated, the overall attenuation is actually not great. What we can't stand most at ordinary times is actually some small noises that are irregular for a long time, and we won't feel uncomfortable because of the loud noise. Therefore, the top floor is not so quiet.
The upper-middle floor is actually good, because in most communities, the buildings around the upper-middle floor can help this floor bounce back the noise. If you can choose the building in the middle of the community, the noise will be less. As long as the community is quiet enough, there will be no noise outside the community on the upper and middle floors.
Sometimes the lower floors may be quieter than the higher floors. Speaking of which, many people will definitely say impossible. But it's also true. Why do you say that? Because now, whether it is road greening, the greening of the community is better. These green vegetation can block the noise at the bottom and attenuate the indoor noise. In contrast, the noise of a slightly higher floor can be directly transmitted without being blocked, which is why the ground floor is quieter than the high floor.
