How Is Sound Insulation Glass Sound Effects ?

- Nov 25, 2016-

Now the market is known as the main three kinds of sound insulation glass, the three different characteristics of sound insulation glass, performance is not the same, we analyze their characteristics, to see the sound glass.

The first is a double insulating glass, is now widely used by many developers, the main function is to heat insulation for high-frequency noise (such as people speak the sound) have a certain sound insulation, but for the low-frequency noise Car, machine running noise) sound insulation effect is not obvious.

The second is a multi-layer of solid sound insulation glass, the middle of a super-elastic sound insulation film, the glass section is similar to the car's windshield and bank counter bulletproof glass structure, the effect of 35 dB after the installation, the basic can not hear the noise, In the suburbs, nursing homes, high-end hotel environment. For high frequency / intermediate frequency, low frequency noise has a good sound insulation.

The third is the vacuum glass, the vacuum glass is generally composed of two 4mm thick plate glass composition, the middle of two layers of glass to stay about 0.28mm space thickness for vacuum. Vacuum glass is better than insulating glass in sound insulation performance, because the air inside the insulating glass is the same as the outside, it is the medium of sound transmission, and the vacuum glass is near vacuum, and the noise in the vacuum state can not be conducted. This type of soundproof glass is generally used in laboratories, recording studios and other places do not need to open the window, and not a wide range of civilian, and the price is high.

In fact, the vacuum glass in the pumping vacuum, the two pieces of glass is almost attached together, so the production of vacuum glass in the glass lining between some minor support, these support has become a sound transmission medium. So no matter what the noise can not be completely separated from all the noise of glass, can only be reduced to a certain extent.
