Abstract
Due to its unique physical sound insulation performance, aluminum alloy foam has become one of the new decorative building materials. Research on its sound insulation performance has also become a hot topic of materials science and other fields. Firstly, the paper analyzes the acoustic characteristics and the analysis indicators of sound insulation materials through the analysis of aluminum alloy foam characteristics and sound insulation mechanism. It finally concludes impact factor of sound insulation based on the analysis model of physical characteristics of aluminum alloy foam and sound insulation mechanism which provides a theoretical basis for the application and development of the sound insulation materials in a certain extent.
