Is the higher the floor the noisier Why the higher the floor, the louder the noise

In the process of communicating with friends, I will always hear some friends say that the higher the floor, the noisier, while others say that the lower the floor, the noisier it is! Is it a high floor or a low floor? It depends on what kind of noise environment the house is facing.

Let's take a 30-story building as an analogy. If the building is surrounded by roads in all directions, then the higher the floor, the noisier it will be, because the higher the floor, the more noise sources can be exposed, such as living on the 25th and 30th floors, and even the noise from the road a few kilometers away will be received;

If the noise source around the building is only a road ahead, then the middle floor will be particularly noisy, and the trees or sound insulation screens on both sides of the road will help the low-rise residents block part of the noise, while the high-rise will be relatively small because of the distance from the noise source! Customers who live in the middle floors (such as 6-25 floors) are not so lucky, and the noise will be easier to enter the house.

Therefore, whether the higher the floor, the more noisy or the lower the noisy, has to be analyzed on a case-by-case basis. According to the specific noise situation, the sound insulation plan is the best solution for you!

The level of noise should be judged according to the type of noise source and the environment around the detection point. From a professional point of view, according to the principle of sound wave transmission, the farther away from the source of the noise, the lower the noise. However, in real life, if there is an obstruction around the lower floors, some of the noise can be blocked to a certain extent.

In addition, the noise level will vary depending on the time, location, and surroundings. ”

The idea that the higher the floor, the farther away from the ground, the less noise there is, is wrong

Less noise on the 1st-4th floors, e.g. villas

The noise from the 5th to 10th floors will be a bit loud, and the main noise will come from the vehicles on the ground

The 11th-20th floors will be quieter and have a moderate distance from the ground

This floor is generally moderate, with less dust and less noise. If you can ask the developer to use good soundproofing materials, soundproof glass, it will be really quiet. But on the 23rd floor, there is really no way, there is no sound after the windows on the 12th floor of the seventh floor are closed, and in my house, the windows can't block the sound of the car.

Noise, why is it louder with higher floors?

Many people like to buy a house facing the street (or road) because of the convenient transportation, superior geographical location, prosperous business and complete living facilities around. Everyone usually says that houses facing the street (or road) are very noisy, but what are the noisiest floors of the high-rise houses facing the street?

Nowadays, there are many sources of noise in the city, and noise has a great impact on people's condition. For example, it will affect people's appetite, sleep quality, etc., resulting in poor physical and mental state. Normally, people think that the lower the floor, the more noise they will receive, but in fact, the sound travels upwards, and the upper floors will also be troubled by noise.

Above the 5th floor, the noise decibels increase as the floor rises, and when the floor reaches a certain height, the noise decreases. Generally, the noise is the highest on the 5th to 24th floors, with the highest noise rising from the 11th to 22nd floors, and quieter on the 30th floor and above. If it is a 26-storey building, the 20-22 floors are the most noisy.

What is the reason for the noise on the middle floors of high-rise residential buildings adjacent to the street?

Relevant experts believe that:

The level of noise is determined by the type of noise source and the surrounding environment.

From a professional point of view, according to the principle of sound wave transmission, the farther away from the noise source, the lower the noise. However, in real life, if there are obstructions around the lower floors (such as green trees, etc.), some of the noise can be blocked to a certain extent. In addition, the noise level varies depending on the time, location, and surroundings.

Sound travels back and forth between different obstacles, reflects, refracts, diffracts.

So how do you explain that the noise on the middle floor is higher than that on the upper or lower floors?

Road noise is largely transmitted by the reflection of the road surface, so the higher the floor, the more exposed it is to the three-dimensional propagation of sound waves, and the more reflected waves (sound waves) are received. However, the sound attenuates as the distance increases, so the noise will gradually decrease after reaching a certain critical level. That's why the middle floors are noisier than the lower and upper floors.

Four ways to reduce noise pollution in your home.

The first trick: the wall. Use wallpaper or "soft package" decoration, cultural stone and other decoration materials to make the surface of the wall rougher, so that the sound waves are refracted many times, so as to reduce the noise.

The second trick: furniture. The amount of furniture placed in the home should be moderate, the choice of wood furniture will have a good sound insulation effect, and wood fiber furniture is porous and can absorb noise.

The third trick: cloth art. The sound-absorbing effect of fabric products is well known, such as curtains, carpets, etc., and the sound insulation effect of curtains is the most important.

The fourth trick: glass bricks. Transparent glass bricks are applied to exterior walls or interior partitions to provide good lighting and a sense of continuity. The glass brick is a low-penetration sound insulation body to block noise interference.

Buying a home is a very important thing, and it needs to be carefully considered and selected, as well as discussed and agreed with the family, and avoid some minefields of buying a house as much as possible. There are many factors to consider about suitable floors, some people are afraid of heights, some people like quiet, young people are afraid of noise, and older people prefer lower floors. Therefore, what kind of floor to buy needs to be decided by each buyer according to their own needs and considerations.

Experts have found that noise travels upwards, with noise in high-rise residential buildings ranging from 30 to 70 meters. On the contrary, low places, there is very little noise. In addition to the fact that green belts and street trees reduce noise, this is also because the lower floors can only receive noise at close range.

The higher the floor, the wider the noise reception range, and the long-distance traffic noise can be transmitted to the upper floors.

Monitors have found that the noise decibel level will increase with the increase in floors above the fifth floor. When the floors are higher, the noise decreases again. Generally speaking, high-rise buildings have 5 to 24 floors of noise, with 11 to 22 floors being the most noisy, and more than 30 floors being even quieter.

The upper and lower layers have different forms of noise pollution. 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 layer is exactly an integer multiple of the wavelength of the noise wave.

This is because there are no buildings around the high-rise building, which is completely exposed to the three-dimensional propagation of sound waves, so there is a lot of noise. However, when noise begins to attenuate at a certain height, residents of higher floors are less affected.

Why are the residents of low-rise buildings also frightened by the noise?

Traffic noise is an important part of urban environmental noise pollution, and its "energy" usually accounts for 70% or 80% of the total energy of environmental noise. In recent years, traffic noise has replaced construction noise as the source of most complaints. The rapid growth of motor vehicles is the main reason for the rapid growth of traffic noise.

The first factor contributing to the increase in traffic noise pollution is the sharp increase in vehicles. A large number of vehicles are crowded on the road. An increase in sound production capacity is inevitable.

Noise, why is it louder with higher floors?

This is because the higher the floor, the louder the wind. As long as the windows are not closed tightly, there will be a lot of noise.

I think it's because the quality of people at the top is generally low.

This may be due to the fact that when the floor is higher, the plane will fly overhead.

I think there's a lot going on for this kind of thing.

Noise, why is it louder with higher floors?

In the absence of sudden noise, viaducts and other factors, the noise of each floor of the building is not very different, and the noise level will vary depending on the time, location and surrounding environment.

My family lives on the 24th floor, and to be honest, the outside sound is really not very small, and I don't think the noise can be judged by the height of the floor.

Or if you live on the first floor, you are used to hearing the outside sound, so you don't feel anything, but if you live on the upper floor, the sound seems to be similar, and if you open the window, the sound will become louder.

Neither is it. The noise distribution of high-rise buildings is characterized by "small at both ends and large in the middle", and the noise is the highest between 30 and 70 meters for high-rise residential buildings.

In addition to the fact that the green belt and street trees can reduce the noise, but also because the low floor only receives the noise at close range, and the higher the floor, the wider the range of the received noise, and the long-distance traffic noise can be transmitted to the high-rise. When the floor reaches a certain height, the noise starts to attenuate.

Generally speaking, if there is only one road around the building, the noise is the highest on the 10th floor of the building, and the rest of the floors decrease according to the distance around it. If there are multiple roads around the building, the noise will be the highest on the 25th floor, and the rest of the floors will decrease according to the distance between them.
