Noise pollution is called the "invisible health killer." Under the epidemic, Korean people spend longer at home, and the problem of noise pollution between floors in residential communities is becoming more and more serious. The demand for related products that can reduce noise continues to increase.
The sales of noise reduction products in South Korea have skyrocketed. According to the statistics of South Korean government departments, after the outbreak of the epidemic, many people work at home and have fitness and entertainment. Last year, relevant agencies received complaints about noise between floors from community residents increased by 60% year-on-year, and the number exceeded 40,000 for the first time. As for the causes of noise pollution, they include people jumping and running, dragging furniture, and the sound of certain musical instruments and fitness equipment. In order to avoid intensifying the conflicts between neighbors, many Koreans have recently begun to spend their minds on reducing noise. In the past two months, the sales of noise-reducing floor mats on a large online shopping platform in South Korea have nearly doubled year-on-year, and the sales of indoor noise-reducing slippers, tables, chairs, and sofa sound-absorbing floor mats have also increased by 86% and 37%, respectively.
In the home furnishings store, a variety of carpets of different colors and materials have recently become popular products in the store. With sound-absorbing function, families with children or pets like this product. At the same time, the recent sales of goods such as soundproof blankets and shock-absorbing mats that can be used in gyms and other places are also very good.
Currently, South Korea’s building materials and construction industries are also beginning to explore noise reduction business opportunities. Some building materials companies have introduced floors with sound-absorbing functions, using sound-proof materials and increasing the thickness of the floor. Many large construction companies in South Korea set up inter-floor noise research institutions this year to analyze the causes of noise and develop new construction techniques. In order to solve the problem of noise pollution between floors in the longer term, the Ministry of Land, Infrastructure and Transport of Korea has also decided to thicken the floor slabs of newly built buildings from next year, and at the same time change the measurement of noise between floors from before completion to after completion. At the same time, regarding how to conduct scientific determination and how to conduct scientific construction, relevant parties in South Korea are continuously exchanging opinions with the academic and business circles, striving to issue relevant standards as soon as possible.
With the rapid increase of urban and rural industries, traffic and population, various noises flood our surrounding environment, especially in cities. Due to site restrictions, many residential buildings are built in downtown or near factories. The noisy human voices, the roar of cars and the vibration of machines broke into our room without mercy, making us lose the peaceful rest environment of the past. Noise has become one of the public hazards that pollute the human social environment, and it has become the three major pollution sources alongside air pollution and water pollution.
For the average person, the human body's ability to withstand noise is about 50 decibels. The increase in noise sound pressure will increase the harm to the human body accordingly. The lighter ones will make people feel irritable, affect people's working mood and reduce labor efficiency; the heavy ones will cause hearing fatigue or even be severely damaged. The survey materials show that the hearing perception of some urban residents has been lower than that of rural residents to varying degrees. Due to the long-term strong disturbance of noise, many adults are nervous, dizzy, heart palpitations, trembling of hands and feet, movement disorders, high blood pressure, heart disease, neurasthenia and other diseases. Pregnant women and children suffer more severely. Moreover, long-term noise disturbance can cause wall cracks, falling gray roofs and shortening of indoor equipment life in the building itself.
Currently, the noise reduction products of Zhengsheng have been widely used in Chengdu Metro, with a 50% share. In the national subway muffler equipment, the share has reached 25%. The world's largest Guquan converter station, the Lhasa converter station on the Qinghai-Tibet Plateau, and the Chengdu Second Ring Expressway also have Zhengsheng products.
Whether it is the "Green Building Action Plan" or the "National New Urbanization Plan (2014-2020)", China's short- and medium-term goals for green buildings are focused on increasing the green ratio of new buildings, which is in line with the current rapid urbanization in China Stage characteristics and the status quo of the initial stage of the green building market. Among the 40 billion square meters of buildings in stock, 99% do not have green building certification, and a small part of them may actually meet the requirements of green buildings, and this scale is still growing at a rate of more than one billion square meters per year. The large number of existing buildings means that building energy saving and emission reduction is facing huge challenges and potentials in China.
In 2016, the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development jointly formulated and issued the "City Adaptation to Climate Change Action Plan" to implement the requirements of the "National Climate Change Adaptation Strategy", effectively improve the ability of Chinese cities to adapt to climate change, and coordinate urban adaptation to climate as a whole Change related work. The plan pointed out that by 2020, it will be achieved universally to incorporate climate change-related indicators into the urban and rural planning system, construction standards, and industrial development plans, and 30 pilot cities to adapt to climate change will be built. The governance level of typical cities to adapt to climate change will be significantly improved, and the proportion of green buildings will be promoted. Reached 50%. By 2030, the scientific knowledge of adapting to climate change will be widely popularized, the ability of cities to deal with waterlogging, drought, water shortage, high temperature and heat waves, strong winds, and freezing disasters will be significantly enhanced, and the ability of cities to adapt to climate change will be comprehensively improved. Under the background that green development has been written into China's national policy, relevant departments will further highlight the focus of financial support, and environmental protection industries such as green buildings have also entered a policy dividend period.
With the improvement of people's living standards, the higher requirements for living comfort, and the higher and higher requirements for noise prevention, the demand for sound insulation materials has increased significantly, which has effectively promoted the rapid development of the industry. In the future, the total sales output value of the national heat and sound insulation materials industry will continue to grow.
