With the development of the city, the road is more and more and wider, and car ownership is also rising, so by the side of the road, the biggest problem is how to reduce the noise of the road, when I bought a house in 16 years, I also deliberately selected the house towards the road, because I like to north-south through the house, but I bought a house has been taken into account the problem of noise on the road, and think of the good! The solution. Now there are friends are asking: home windows are double-glazed, but sleep against the road is very noisy, what is a good way to reduce the noise? Next for you to do a detailed analysis, I hope to help you in how to deal with the noise problem!
City noise source analysis and influencing factors?1, what are the sources of urban noise?
Urban noise has three types of construction noise (construction site construction), traffic noise, living noise (playing mahjong, square dancing, etc.), but the traffic noise is the most difficult to deal with, and the continuing impact of a longer period of time.
Cause Analysis: Traffic noise comes from the sound of car tires rubbing against the ground, concrete highways are more serious than asphalt ones, the sound of car engines, exhaust pipes, car horns, wind resistance, brakes, speed bumps and other sounds.
Solution: There is no very good solution for traffic noise external, such as planting trees with lush foliage on both sides of the road, turning concrete roads into tarmac, and turning all fuel cars into electric cars, which can indeed reduce traffic noise a lot, but in the process of urban development, these are not easy to realize quickly and out of our control.
2, affecting the size of the traffic noise of several factors
The closer the highway the greater the noise, from the highway on the same plane distance, the higher the floor the greater the noise, for the 32-storey high-rise building, that live in a higher point of the noise becomes smaller idea is wrong; adjacent to the highway speed is higher, the greater the noise, such as the highway noise is greater than the average highway noise; adjacent to the highway noise is greater than the average highway noise; adjacent to the highway noise is greater than the average highway noise; adjacent to the highway noise is greater than the average highway noise. The higher the speed of the neighboring highway, the greater the noise, such as highway noise than ordinary highway noise; the higher the traffic flow of the neighboring highway, the greater the noise, the noise of the main road is certainly greater than the noise of other municipal roads; such as the highway will have a section of the noise barriers, the noise is lighter than not, the front of the building blocked, the noise is a lot lighter, because the wall can play a very good role in soundproofing. Roadside noise is how the indoorReason Analysis: Noise is divided into low-frequency and high-frequency noise, high-frequency noise with the distance farther away or encountered obstacles, can be rapidly attenuated, every 10 meters away from the 6 decibels can be reduced. While low-frequency noise is extremely penetrating, decreasing very slowly, the sound wave and longer, can easily cross the obstacles, so the noise heard indoors are basically low-frequency noise, the current building wall blocking low-frequency noise effect is still good, the building's exterior walls have insulation, the effect will be even better, but the most critical point is the noise is transmitted to the interior of the room is mainly through the window, you open the window and close the window, the noise size is completely different! The most important point is that the noise is transmitted to the interior mainly through the windows.
Solution: Through the analysis of the noise problem, or through the window to solve the problem, the window sound insulation effect is good, the noise will be small, but not what the window can be a good blocking noise.
Note: Low-frequency noise refers to the frequency of 200 Hz (octave range) below the sound, in the human ear range is in the 20Hz - 200Hz is low-frequency, that is, in a second vibration 20 to 200 times the irregularity of the sound issued by the noise is called low-frequency noise.
Solutions: Through the analysis of want to solve the noise problem, or to solve through the window, the window soundproofing effect is good, the noise is small, but not what the window can be a good barrier to noise.
ConclusionThe noise of the road is indeed very noisy, if your home is also this way, it is recommended not to do double-glazing, replaced by broken aluminum + laminated glass, or use the best solution, broken aluminum + triple laminated insulating glass, which can greatly reduce the low-frequency noise of the road.
