City noise has become an important part of the pollution of the environment, not only interfere with the normal life and work of the people's physical and mental health has also been a serious impact. Noise pollution include industrial noise, social noise and traffic noise, with the rapid expansion of urban motor vehicle ownership, the more exciting the rapid development of the construction of transport facilities, which have urban freeway traffic trunk, suburban building, These new transport facilities makes it very difficult to find a quiet place in the city. Therefore, how to solve the noise nuisance has become the focus of attention of the people of today. Bebel static soundproof windows passive means to solve the traffic noise, but the effect is more obvious, proved Bebel static soundproof windows, interior noise can be reduced to less than 40dB installed in more serious areas of road noise. EPA in order to solve the inner ring elevated noise nuisance problems, experts argued that the noise reached more than 30dB Bebel static soundproofed windows as standard soundproof windows noise reduction project within the loop. That soundproof amount to define soundproof windows. Along the inner ring road on both sides of the environmental noise is generally 76-78dB, some sections can reach 83dB, window insulation indoor noise can reach 35-46dB. The effect is more obvious, however, the sensitivity of sound differences;, such as those living in the city roads are road traffic noise, the difference will be because of the different regions in which mini-van, the noise is mainly in low frequency, while living large truck traveling in the path of urban and suburban areas, more noise energy is concentrated in the low-frequency, live in the same upstairs there is also because of the different floors by noise hazards also different, usually noise and low-level low, senior ten layers compromised. Soundproof windows so I chose to proceed from reality, and the specific conditions, can not be stereotyped.
