40 meters from the road 16th floor noise

The 16th floor, which is 40 meters from the road, may be affected by road noise. If there is no obstruction, the noise may be loud.

In order to reduce the impact of noise, the following methods can be taken:

Use double-layer soundproof windows: Choose double-layer insulating glass soundproof windows with a thickness of more than 5mm, as well as soundproof strips and plastic steel casement sealing windows with good sound insulation effect, which can effectively reduce noise.

Choose casement windows: casement windows are 2 3 dB more soundproofing than sliding windows.

Install rough walls: Walls that are too smooth are prone to echoes, which can increase noise. Wear rough walls, such as wallpaper, diatom mud and other decorative materials with good sound insulation.

Placement of greenery and wooden furniture: Shrubs and broad-leaved trees commonly found in cities reduce dust, and the porous fibers on the surface of wooden furniture provide good noise reduction.

Use curtains for sound insulation: The most important material for sound insulation is curtains, and velvet curtains have the best sound insulation.

Use a variety of soundproofing materials: such as soundproof felt, wave sound-absorbing sponge, polyester fiber-absorbing sound-absorbing panels, etc.

The broken bridge aluminum profile with stronger sealing and sound insulation can isolate the external car noise.

At the very least, double-layer laminated glass or vacuum glass should be used to isolate the outside car noise to the greatest extent.

Please note that the above methods are for reference only, and the specific implementation effect may vary depending on the actual situation. If you may be affected by road noise, it is advisable to seek the help of a professional so that a more concrete solution can be developed.

The noise is louder, if there is no shelter between the house on the 16th floor and the road, it will still be noisy, and the probability of being affected by the road noise is greater, and the lower the floor, the more serious the noise impact. If you buy a house close to the road, it is best to do a good job of soundproofing, especially the window soundproofing. It is recommended to choose broken bridge aluminum with stronger sealing and sound insulation for profiles.

The glass should be at least double-laminated glass.

or vacuum glass to isolate the outside car noise to the greatest extent.

It's okay. The first high-rise is soundproof glass, you basically can't hear the sound outside after closing, second, 50 meters of roadside, to your house 14 floors in a straight line distance of 65 meters, I can tell you responsibly, the Chinese New Year double ring is also 6 stories as high, so unless you set off a cannon in front of your window, you can't hear anything at all. You can live well.

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.

Basic concepts. A type of sound that causes irritability, or is too loud and endangers human health.

Noise not only affects hearing, but also adversely affects the cardiovascular system, nervous system, and endocrine system, so some people call noise "a deadly chronic poison".

Note: According to the norms of the National Committee for the Examination and Approval of Scientific and Technological Terms, "noise" is the standard translation of noise, and "noise" is a non-standard usage, because "sound" is a physical term that refers to mechanical waves that can cause hearing, while "sound" is a usage in the humanities field and refers to regular musical sounds, so the two cannot be confused.

The noise of cars heard on the 8th to 14th floors is much louder than that heard on the 1st floor. This is because the path of sound waves depends on the number of trees and buildings. Sound usually travels in the shortest possible route, and sometimes the noise on the main line is also heard on the upper floors, and it turns out that sometimes the sound will go up freely to the windows of the upper floors.

Sound waves propagate in three dimensions, and the upward ones are not weaker than those on both sides, and the sound waves received by high-rise buildings are stronger than those on the lower floors of the same building. However, the lower floors are relatively less noisy due to the obstruction and absorption of the surrounding low-rise buildings and trees, which is also a factor that cannot be ignored when choosing a residence.

In general, the building is at least 100 meters away from the road to be noise-free.

If it's a lower floor, it's definitely noisy. If the building is on the 6th floor, the noise will be reduced. After all, the scope of sound source pollution is huge.

For vehicles on the road, even if you live on the top floor, you will be affected by noise. If you install soundproofing, it will be much better to go up the 6th floor. Of course, it does not include the floors in the Lianchun Viaduct area.

Standard clean room noise should meet the following requirements:

1. During the dynamic test, the noise in the clean and fierce room should not exceed 70 B.

2. During the empty test, the noise level of the turbulent clean room should not be greater than 60 decibels of Yuzhao Bridge; The noise level of a laminar flow cleanroom should not be greater than 65 decibels.

3. Due to the limitation of technical and economic conditions, or when the noise is greater than 70 decibels and has no impact on production, the noise level can be appropriately relaxed, but it should not be greater than 75 decibels.

4. Noise of more than 50 decibels will affect people's normal rest, and more than 70 decibels will interfere with conversation, affect work efficiency, and even accidentsLong-term work or living in a noise environment above 90 decibels can seriously affect hearing and cause other diseases.

1. Generally speaking, the closer you get to the house on the side of the road, the noisier it will be, and the lowest one will be the noisiest. For houses on the side of the road, if the floor is on the 5th floor or not, the noise level of the house will decrease as the floor rises. Houses under five storeys near the road are the noisiest, especially at night when it is quieter, when the hustle and bustle of the big city is quiet, and all the noise at night is extraordinarily noticeable.

2. According to the relevant test data, the noise of the middle floor of the residential building of the high-rise residential building adjacent to the street community is relatively large. According to the basic principle of sound wave frequency transmission, the farther away you are from the source of the noise, the lower the noise will be. However, in real life, if there are some obstructions around the lower floors, then some of the noise can be blocked at a certain level.

3. For noise, the time, location and surrounding environment are different, and the magnitude of the noise will be different. Therefore, the magnitude of the floor noise needs to be determined by the proximity of the noise source and whether there are obstructions. Buyers will be able to distinguish the level of noise based on the type of noise source, as well as the detection point and the surrounding natural environment.

We can add soundproofing materials to the wall near the road, which usually have foam board or sound-absorbing cotton, which can effectively absorb noise, so as to block outdoor noise from entering the room.

Standing higher and seeing farther, many citizens now tend to buy high-storey residences, but move in.

The noise decibels of high-rise buildings are "small at both ends and large in the middle", with floors 5 to 24 being noisy and above 30 floors becoming quieter.

High-rise buildings of 30 to 70 meters are noisy, and many people like to live in high-rise buildings, not only because they can stand high and see far, but also because they are far away from the road and are less affected by traffic noise such as traffic. In fact, it is not so simple to try to be quiet, and the noise pollution from the upper floors is also very large.

The upper and lower floors are exposed to different forms of noise pollution. For the lower floors, the noise source is vibration and sound. For high-rise residents, the effect of vibration is constantly attenuated, but sound is transmitted in the form of sound waves, and noise is very noticeable when the height of a floor is exactly an integer multiple of the wavelength of the noise wave.

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

What is the relationship between noise and floor distribution?

The study found that the noise propagated upwards, with high-rise residential buildings being noisy between 30 and 70 meters. 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.

The test of the monitoring personnel found that above the 5th floor, the noise decibels will increase with the increase of the floor, and when the floor is higher, the noise will decrease again. Generally speaking, in high-rise buildings, the 5th to 24th floors are noisy, with the 11th to 22nd floors rising the most, and the 30th floor and above are quieter. If it is a 26-storey building, the 20-22 floors are noisy.
