Theory and Analysis of Sound Insulation Performance of Composite Tempered Vacuum Glass

Tempered vacuum glass, as a new generation of energy saving and environmental protection glass, not only has the characteristics of safety and high strength, but also has heat insulation, sound insulation and other superior performance. In this paper, the acoustic wave transfer model of composite tempered vacuum glass was established, and the formula of sound insulation was deduced by using wave transfer method (WTM), and the sound insulation loss of composite tempered vacuum glass under the influence of different factors was analyzed theoretically. The results show that the sound insulation performance of composite vacuum glass is significantly higher than that of single glass, i.e. the thicker the glass, the higher the sound insulation loss, at the same time reducing pillars also increases the property of sound insulation. The thickness of vacuum layer has different sound insulation loss in a different frequency, and the sound insulation performance of tempered vacuum glass is relatively best when the thickness of vacuum layer is about 0.25 mm. This research has an important guiding significance for the analysis of sound insulation performance of other similar structures and the selection of sound insulation structure of buildings.
