建築材料特性對隔音量之影響

The Acoustical Properties of Materials on the Effect of Sound Isolation

摘要


本文內容針對現有的板材,找尋出影響板材穿透損失的特性參數,包含單層材與複層材的形式,探討密度、波松比、損失因子與楊氏模數等參數對吻合頻率及隔音量的影響。並以理論及軟體計算進行模擬比較,以確認數據之正確性,經由一系列之模擬計算分析可以提供設計隔音材如何選擇對隔音效果提升之重要參數。

In this thesis we study the existing acoustical materials to find out the amount of influence parameters to the effect of the transmission loss and coincidence frequency, including signal partition and composite partitions. The acoustical parameters include density, Poisson ratio, loss factor and Young's modulus. The results are assured with the theoretical and software simulation. After a series of calculation and simulation, the important affect factors to increase noise reduction can be proper selected and designed.
