A good environment has many indicators of measurement, but the quality of sound is undoubtedly one of the hard indicators. We live in a world of sound, but when the sound is too loud and becomes noise, it will cause harm. According to international standards, in the downtown area, the noise outside can not exceed 55 decibels during the day and 45 decibels during the night; the general residential area cannot 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 damaging hearing, noise can affect other systems of the body, causing some physical symptoms such as insomnia, neurasthenia, autonomic dysfunction, and unstable blood pressure. People who are usually affected by noise can develop irritability, fatigue, difficulty in concentration, and unresponsiveness.
Door and window renovation is focused on sound insulation
If your home is facing the street, it is best to replace the ordinary glass on the street window with soundproof glass. Because the soundproof glass is thicker, the ordinary window rails cannot be docked, so the window frame should be modified. If a transparent glass of 5 mm to 8 mm thickness is used, the noise can be reduced by more than 30 decibels after installing the soundproof window. Double-glazed sound insulation is about 40%, while three-layer glass is almost 100% soundproof. The use of plastic doors and windows with good sealing performance can save energy by 30% to 50%, and can reduce the indoor noise to 1/3 of the outdoor, maintaining at around 30 decibels.
The sound insulation of the door is mainly determined by the filling of the core of the door. The inner core is filled with a paper-based molded soundproof door that achieves a sound insulation of 29 decibels. The inner core is made of high quality particleboard door and the sound insulation can reach 32 decibels. Solid wood doors and solid wood composite doors, the higher the density, the heavy weight, the thick door panels, the better the sound insulation effect. If the door panel is engraved with patterns on both sides, it can play a certain role in sound absorption and prevent repeated refraction of sound waves than a smooth door panel. The fire door with sealing strip around the door also has good sound insulation. In addition, the installation between the door cover and the door is also the key to determine the sound insulation effect. Experts recommend that door covers and doors should be installed by experienced professionals.
Wall decoration to prevent reflection
Too smooth walls and floors will reflect sounds, such as wallpaper, "soft bag" decoration, or cultural stone decoration materials, roughen the surface of the wall, so that the sound waves can be refraction multiple times, thus reducing noise. For large-sized households, a layer of gypsum board can be added to reduce noise. Small-sized households can be covered with cork on the wall. The walls are first separated by solid wood and are covered with cork. After the wall is remodeled, the noise is reduced by more than 50 decibels.
Walking on a hard laminate flooring often makes a louder sound, especially at night. Silent cork flooring can be used for this purpose, and the floor has a sound absorbing and sound insulating function by increasing the elastic index and the static bending strength of the floor.
How to absorb sound in household items
The number of furniture placed in the home should be moderate, and it is easy to make the sound resonate in the room, and it is easy to hit the east. Wood furniture will receive good sound insulation, and the wood fiber home is porous and absorbs noise. Different woods have different levels of sound absorption, and softer woods absorb more sound, such as pine. Also pay attention to the sliding door of the cabinet and the drawer of the desk. The hardware is preferably muted so that there is no noise when pulling. Place the bookcase in front of the wall adjacent to the neighbor's home, and properly block the sound from neighbors.
The sound absorption effect of the fabric is obvious, so it is also more effective to use the cloth to eliminate the noise. Tests have shown that drape and tiled fabrics have the same sound absorption and effect, such as curtains, carpets, etc., while the curtains have the most pronounced sound insulation.
Household appliances are the main source of noise in the home, so pay attention to the use of silent household appliances. When choosing air conditioners, refrigerators, washing machines, range hoods, it is best to use the noise level as one of the selection criteria when purchasing, especially the air conditioners installed in the bedroom and living room.
The color of the room should be soft
Quiet home life, not only the auditory environment, but also the visual experience. In terms of indoor light, if the color of the ceiling, floor or wall is too bright, it will interfere with the central nervous system of the human body, making people feel upset and extremely sensitive to noise. Therefore, attention should be paid to the soft color of the lighting in the selection of various lamps and decorative materials for interior decoration.
The color in the home, it is best to avoid using some of the impact of the color, try to use a soft intermediate color, for example, beige, beige is a home color that is easy to make people quiet.
Spatial arrangement
To make your home fresh and quiet, there are some basic spatial mute logic methods. For example, when a person is in a home decoration, he or she can ask the designer to realize the “moving and static division†of the home according to the characteristics of the house. 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 in the home should be smooth. From the bedroom to the bathroom, this is a “peak†path in the morning. From the restaurant to the living room, this is the main path for noon and evening... From one area to another, although it is a few steps, the design of this small passage is still Very knowledgeable, the path of these connection spaces is best to pass, and to be smooth. If you walk a chair from the bedroom to the bathroom, you will feel subconsciously uncomfortable. On the contrary, these paths are very smooth, you will naturally feel the mood. Pleasant.
