碩士 === 國立屏東科技大學 === 木材科學與設計系所 === 101 === This study analyzes domestic floor impact sound insulation design techniques and technologies, to master a variety of floor impact sound insulation mechanism. While the domestic heavy floor impact sound for the past few specimens were studied in small piece. The experiments carried out in addition to the use of small specimens outside floor impact sound of the study, also set the standard for multi-Measurement of specimens, In addition to assessment of its impact sound insulation performance, and with the small specimens were analyzed. The results show that the raised floor wooden structure and direct shop-type floating floor to floor impact sound of the improvement is more excellent high-frequency. Although, rise wooden floor could reduce the lightweight impact sound pressure level. In the without resilient layer under the conditions, impact sound pressure level could deterioration of heavy impact source. Change the glass wool and rock wool the resilient layer thickness than lower density,more effective in reducing lightweight floor impact sound. Also in the standard test small specimens of research, can be found in small specimens direct wooden shop-type and raised floor can accurately predict the standard specimen of measurement results. For this study, the production of floating floors on a number of studies conducted.and make the process more clear,f or future research and building construction and design reference.
