Description
Technical Field
The utility model relates to an indoor timber of silence. Belong to indoor timber technical field.
Background
Indoor doors are the main sound insulation members of indoor building components, but the current national standards do not make detailed regulations on the sound insulation standards of the indoor doors. And in fact, national standards do not necessarily meet the experience requirements of everyone on sound insulation. In general, to meet the requirements of quality of life and privacy, the sound insulation of the door and wall combination needs to be more than 45dB to meet the basic privacy. But the average sound insulation level of the domestic indoor wooden door in the current China market is 20dB-25dB, and the sound insulation quantity of a low-grade door (the conventional price is below 1000) is more than ten decibels. The top-grade wood door is 25-33 dB. Some publicity sound-proof 'soundproof doors' are about 25-28dB, and soundproof doors with special structures can reach more than 40dB, but are rare in the market and not very expensive.
The development of modern industry and transportation has made noise pollution one of the important public hazards. Noise can cause hearing impairment, and prolonged periods of intense noise exposure can also cause a variety of physiological and psychological effects, such as dizziness, tinnitus, insomnia, palpitation, loss of appetite, and the like. Roads in large cities are complex and diversified, and people's residence areas are often located on one side of the roads, so that the noise pollution is increasingly serious. The rapid development of industry and urbanization has inevitably increased the degree of noise pollution. Noise from various occasions in life is exhausted. The most direct harm of noise to human body is hearing impairment, which is applied to central nervous system of brain to cause neurasthenia symptoms such as headache, brain distention, tinnitus, insomnia, general fatigue, weakness and hypomnesis. Compared with the situation under the low-noise environment, the incidence rate of hypertension, arteriosclerosis and coronary heart disease of people working in the high-noise environment for a long time is 2-3 times higher. The noise has great harm to the fetus, and the high decibel noise can damage the auditory organs of the fetus and also can cause dysfunction of endocrine glands of pregnant women, thereby causing abortion and premature delivery. The study shows that the future character of the baby in the noise environment for a long time is violent.
