| Outline of Final Research Achievements |
Sound insulation performance of window systems is conventionally predicted based on the energy-based evaluation by replacing various components with simple theoretical models. The simplifications sometimes spoil the prediction accuracy, and are not neccessarily efficient approaches because the modeling is strongly depends on the problems. In this research, we developed a numerical method for predicting and designing the insulation performance of the window system. In particular, we focused on verifying the validity and effectiveness of models of material placement, end support, peripheral gaps and sash frame vibration. Furthermore, mechanisms of sound transmission phenomenon are interpretted during the verifications.
