Measures to deal with more foreign noise noise noise wall thickness Beijing home interior noise walls

Beijing Miki professional noise reduction means more noise to deal with foreign countries in Europe, urban noise is also a big problem. To solve it, countries have introduced a series of regulations and measures to limit noise, large unified action across the EU, small to bath time has prescribed. The most troublesome of the four urban noise issue, but also the focus of rectification countries. --- Traffic noise map can become evidence in court. Data show that, at present, European car-to-noise ratio in 1970 decreased 85%, trucks reduced by 90%. But recent EU survey found that 15 years, the total amount of noise is not significantly reduced EU countries, the main reason is an increase in automobile traffic flow increases and other offset the years of technological progress. To reduce traffic noise, the Europeans want a lot of ways, the most striking is the noise maps. May 2003, Paris took the lead coming up noise maps. In accordance with the noise level from low to high, the entire map of Paris with a green, yellow, red and blue show. In addition to the noise maps, countries have taken many other measures. Sweden actively promote people to buy low-noise vehicles; Japan's urban road sound screen set rate in 1983 reached 80%; Canada is more "close to nature", using natural terrain road noise shield. In recent years, developed a lot of construction noise pavement, road surfaces are porous concrete material, not only absorb noise and can absorb nitrogen dioxide and other exhaust components, very environmentally friendly. At present, China also began laying the road noise, Jinsong Road, Beijing is such a high-tech road, ordinary road noise is lower than 3-5 dB. Do not underestimate this difference, because every traffic noise reduced by 3 dB from the sound source is equal to 1 times away, the noise reduction effect is obvious. Construction --- an obligation to protect the public away from the noise of the construction unit. Newspaper special correspondent in the UK is currently a visiting scholar at the University of Westminster. The university dormitory when stamped, construction machinery are placed behind the new building, the workers never loud conversation.
