There are many indicators to measure the quality of the environment, but sound quality is undoubtedly one of the hard indicators. We live in a world of sound, but if the sound is too loud and becomes noise, it will bring harm to people. According to international standards, outdoor noise should not exceed 55 decibels during the day and 45 decibels at night in busy urban areas; In general residential areas, it does not exceed 45 decibels during the day and 35 decibels at night. If people are exposed to noise for a long time, they will have adverse reactions and may induce "noise sickness". In addition to hearing loss, noise will also affect other systems of the body, bringing some physiological symptoms, such as insomnia, neurasthenia, autonomic nervous dysfunction, unstable blood pressure and so on. People who are usually affected by noise will have symptoms such as irritability, fatigue, difficulty in concentration and slow response. The reconstruction of doors and windows focuses on sound insulation

If your home is facing the street, you'd better replace the ordinary glass of the window facing the street with sound insulation glass. Because sound insulation glass is thick, ordinary window rails can't be docked, so the window frame needs to be rebuilt. If 5 mm to 8 mm thick transparent glass is used, the noise can be reduced by more than 30 decibels after installing the sound insulation window. The sound insulation effect of double-layer glass is about 40%, and that of triple-layer glass is almost 100%. Using plastic steel doors and windows with good sealing performance can save energy by 30% to 50%, reduce indoor noise to 1/3 of outdoor noise and maintain it at about 30 decibels. The sound insulation effect of the door mainly depends on the filler of the door core. The molded sound-proof door with paper inner core can achieve 29 decibels sound-proof effect. The inner core is made of high-quality particleboard, and the sound insulation effect can reach 32 decibels. Solid wood doors and solid wood composite doors, the higher the density, the heavier the weight, and the thicker the door panel, the better the sound insulation effect. If both sides of the door panel are engraved with patterns, compared with the smooth door panel, it can play a certain role in absorbing sound and preventing repeated refraction of sound waves. Fire doors with sealing strips around the door also have 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. Experts suggest that door covers and doors should be installed by experienced professionals. Wall decoration to prevent reflection

Too smooth walls and floors will reflect sound, such as wallpaper, "soft bag" decoration, or cultural stone and other decoration materials to make the walls rough, which can refract sound waves many times, thus reducing noise. Large units can be installed with a layer of gypsum board to reduce noise. Small families can cover their walls with cork. First, divide the wall into geometric patterns with solid wood, and then cover it with cork. After reforming the wall, the noise can be reduced by about 50 decibels. Walking on the hard reinforced composite wood floor often makes a lot of noise, especially at night, which makes people feel uncomfortable. Therefore, the mute cork floor can be used, and the floor has the function of sound absorption and sound insulation by improving the elastic index and bending strength of the floor. How to Sound Absorb Household Articles

The amount of furniture placed in the home should be moderate. Without it, it's easy to make the sound spin indoors, but if you use it too much, it's easy to hit the west. Choosing wood furniture will get a good sound insulation effect. Wood fiber furniture is porous and can absorb noise. Different kinds of wood have different sound absorption degrees, and softer wood absorbs more sound, such as pine. Also pay attention to the sliding door of the cupboard and the drawer of the desk. Its hardware should be silent, so there is no noise when drawing. Putting the bookcase in front of the wall adjacent to the neighbor's house can properly block the voice of the neighbor's house. The sound absorption effect of fabric is obvious, so it is also an effective method to eliminate noise with fabric. Experiments show that the sound absorption effect of suspended and flat-laid fabrics is the same, such as curtains and carpets, and the sound insulation effect of curtains is the most obvious. Household appliances are the main noise source in the home, so we should pay attention to choosing quiet household appliances. When choosing air conditioners, refrigerators, washing machines and range hoods, it is best to take the working noise level as one of the selection criteria when purchasing, especially the air conditioners set in bedrooms and living rooms. The color of the room should be soft.

Quiet home life includes not only auditory environment, but also visual experience. In terms of indoor light, if the ceiling, floor and walls are too bright, it will interfere with the central nervous system of the human body, making people feel irritable and particularly sensitive to noise. Therefore, in the choice of various lamps and decorative materials for indoor decoration, we should pay attention to the soft color of light. It is best to avoid using some colors that are too impactful, and try to use soft middle colors, such as beige and beige, which are easy to make people quiet. Spatial layout of static and dynamic separation

There are some basic logical methods to make the home refreshing and quiet. For example, when people with conditions decorate their homes, they can ask designers to realize the "dynamic and static partition" of their homes according to the characteristics of their homes. The actions of a family at home often cause mutual interference, so it is necessary to divide the rest area and activity area at home to minimize interference. The path at home should be unobstructed. From the bedroom to the bathroom, this is a "peak" path in the morning, and from the dining room to the living room, this is the main path at noon and at night ... From one area to another, although there are only a few steps, the design of this small passage is still very learned. The paths of these connecting spaces should be smooth and smooth. If there is a chair on the way from the bedroom to the bathroom, you will feel very uncomfortable subconsciously. On the contrary, these paths are very smooth. you
