Prediction on Modal Properties of Building Plates

Abstract:

Statistical energy analysis (SEA) method is an adequate tool to solve complex problems to building acoustics. This research on the application in variety of the building materials as the subsystem of SEA model is performed. For the purpose to explore the relationship between the building element and its mode, these commonly used building materials are selected to determine this relationship. It is indicated that the properties of building material have obvious effect on the modal density and modal overlap of building members. As the consequence, a useful technique to account for a building member to be appropriate for a SEA (statistical energy analysis) subsystem is presented.
