A bedroom window closure 45 noise decibels big
Bedroom window closure 45 noise decibels is considered big. According to the relevant provisions of the state, the noise in residential areas can not exceed 50 decibels during the day, the night should be less than 40 decibels.

2, the sound insulation effect of the door mainly depends on the core of the door filler. Inner core filled with paper-based molded soundproof door, can reach 29 decibels of sound insulation.
3, the inner core of the door using high-quality particle board, sound insulation can reach 32 dB. Solid wood doors and solid wood composite doors, the more high density, heavy weight, thick door panels, the better the sound insulation effect.
4, if the door plate is engraved on both sides of the pattern, than the smooth door plate, can play a certain role in absorbing sound and preventing repeated refraction of sound waves.
5, surrounded by fire doors with seals, also has a good sound insulation effect. In addition, the installation between the door cover and the door is also the key to determine the sound insulation effect.
Third, how to distinguish the source of the building noise
1, listen to the sound quality
Upstairs the noise is more crisp, sounds clear; downstairs the noise is generally passed up through the floor, sounds muffled.
How to distinguish the source of building noise
2, listen to the audio

Noise that can only be heard when you are lying in bed is likely to come from next door.
A bedroom window closed after the noise decibel is 45, is still big
1, if the bedroom window is closed, the decibel of noise is still 45, indicating that the noise problem still exists. Because in accordance with China's environmental noise emission standards, outdoor noise during the day can not exceed 50 points. At night, the noise should be less than 40 decibels, that is to say, in the bedroom, the noise value if more than 40 decibels or more, it will interfere with people's normal rest, affecting the quality of sleep.
2, some people are more sensitive to noise, it is easy to lead to insomnia, frequent breathing, neurasthenia, etc., the second day of the spirit will be bad, affecting the children's school, adult work.
Second, the noise to which department to complain
1, in the major cities, if you encounter the problem of noise, we can directly to the environmental protection department or public security departments to complain. Because the Environmental Protection Bureau is mainly for night construction or various service industries to manage the noise.

For example, at night if someone renovation, the use of electric drills, electric saws, etc., the noise generated by the problem, you can complain to these departments, are able to be resolved.
3, if on the road, for example, now there are a lot of people like to dance square dance, put a high-decibel horn, can be directly to the city management department to reflect, this behavior is banned, but also will cancel the source of noise.
Bedroom window closed 45 noise decibels big 3Window closed noise 45 decibels is not considered noisy.
Generally speaking, during the day, the noise in the bedroom is to be within 50 decibels, and at night, the noise in the bedroom is not to exceed 40 decibels, otherwise they are considered a nuisance. Bedroom windows closed, the noise 40 decibels, just at this cut-off point, is barely acceptable noise range.
Interior in the process of decoration, you can install a layer of soundproof cotton on the window, which can effectively prevent outside noise into the interior, reduce the impact of outdoor noise on home life. And soundproof cotton budget is not too high, to bring the home effect is also very good, just to buy a high quality soundproof cotton to do.
Bedrooms are susceptible to surrounding noise if they are not soundproofed well.
40-60 decibels belongs to our normal conversation sound. 60 decibels above belongs to the scope of the noisy, 70 decibels we can think of it is very noisy, and began to damage the hearing nerve, more than 90 decibels will make the hearing impaired, and stay in the 100-120 decibels of the space, such as no accidents, a minute of human beings have to be temporarily deaf (deafness). Among them, the car noise between 80-100 decibels, to a car issued 90 decibels of noise, for example, in a hundred meters, you can still hear 81 decibels of noise.
Bedroom noise should not exceed 30 decibels at night and 40 decibels during the day. General noise does not exceed 30 decibels, the human body feels comfortable, if the indoor noise of 46 decibels or more, it will seriously affect the road people's lives, work and study.
House sound insulation how to do
1, wall soundproofing: wall soundproofing can be used soundproofing felt, which can effectively prevent the spread of sound, which is not hard-wired . In the case of installation of good results, if the hard installation is completed, you want to sound insulation can only be pasted on the wall soundproof board or soundproof sponge.
2, soundproof windows and doors: windows and doors are directly combined with the external space, soundproof measures can not be less, solid wood doors and double insulating glass windows soundproof effect is very good.
3, ground sound insulation: If you are concerned about the walking sound will affect the family or neighbors, solid wood flooring is a good choice, because the sound insulation effect of solid wood flooring is far better than tile, before laying solid wood flooring can be paved about 3 cm of soil, and then lay solid wood flooring so that can maximize the effect of sound insulation.
The harm of noise
1, damage to hearing. Relevant data show that: when people listen to motorcycle sound continuously, 8 hours after the hearing will be damaged; if the rock concert hall, half an hour later, people's hearing will be damaged; if the noise in the 80 decibels above the living environment, resulting in the possibility of deafness can be up to 50%.
2, noise damage to vision. Noise can seriously affect the hearing organs, and even make people lose their hearing, as we all know. However, there is a subtle inner "link" between the ear and the eye, when the noise acts on the auditory organs, but also through the role of the nervous system and the "wave" of the visual organs, so that people's eyesight is weakened.
Studies have shown that noise can cause color vision and visual field abnormalities. It was found that among the 80 workers exposed to steady state noise, the red, green and white visual field was reduced by as much as 80%, an increase of 85% over the control group.
The shadow of noise on vision can be seen everywhere in daily life, such as shopping in a quiet and bright store, appearing to be pleasant and calm, buy things can do to pick fine purchase complete. And in the loud speaker playing fast-paced pop music (some of the so-called pop music, but only deafening strong noise) when shopping, often irritable, dazzled, and even mixed haphazardly - the transaction, the buy did not buy, bought due to the identification of not fine and unsatisfactory. One of the main reasons is that the dry sound affects the eyesight caused by.
3, harmful to the human cardiovascular system, the state of the city noise and the health of the residents of the survey showed that: the regional noise increases every decibel, the incidence of hypertension increased by 3%.
4, affecting the human nervous system, making people impatient, irritable. Scientific research has found that noise can stimulate the nervous system, so that it produces inhibition, long-term working in a noisy environment, but also cause neurasthenia syndrome (such as headaches, dizziness, tinnitus, memory loss, vision reduction, etc.).
5, affecting sleep, causing fatigue. The harm of noise on sleep: sudden noise at 40 decibels, can make 10% of the people wake up, up to 60 decibels, can make 70% of the people wake up.
