Therefore, the management of noise pollution has formed a good business opportunity, and different forms of soundproof Windows have been brought to market. Some products are sold without detection. The sound insulation glass is a very good energy saving and insulation material, but its sound insulation performance has no human brain. Wuxi soundproof window In order to understand the sound insulation of the vacuum insulating glass, we first introduce the structure of the vacuum glass: the vacuum glass is a flat glass with two layers of 4mm thick, and the middle vacuum layer is 1.5mm. Double layer 4mm plate glass will absorb together under the negative pressure condition and lose the vacuum layer. Therefore, it is necessary to make a small support to the double glazing when making vacuum glass. These are the sound Bridges -- the sound of solids. I once saw a vacuum glass that was being tested for sound insulation, and the experimental condition was the structure of a double vacuum glass and a layer of hollow glass, where the lower frequencies were less than 18dB. Accurately speaking, vacuum glass is better than hollow glass, and the vacuum glass should be used to make sound insulation window. Further acceleration of urban construction inevitably increases the level of noise pollution. In particular, traffic noise accounts for up to 40 percent of urban noise. Many city dwellers who have been with the road day and night are deeply impressed by this nature. Wuxi soundproof window The intensity of the noise can be expressed at the sound level, in decibels (dB). Noise levels of 3O ~ 40 decibels are relatively quiet and normal environment; More than 50 decibels can affect sleep and rest; More than 70 decibels interfere with the conversation, causing upset and mental disorientat
