"本計畫係針對矽酸鈣板、纖維水泥板或石膏板等常見的隔間建材，搭配泡棉或岩綿等多孔吸聲材料，所組合成的多層型態之三明治結構，進行提升低頻消能的聲學性能研究，由於輕隔間建材有施工效益高、組裝容易、工期縮短等優點，藉由低頻消能的機構設計，提升建材在低頻範圍隔音與吸音的聲學能力。本研究擬採用統計能量法以及多孔材理論，對此多層形式的輕隔間材，進行穿透損失性能研究，，除建立多層板材能量傳遞衰減模式，並藉由實際實驗量測與理論模型相互比對，以確認此低頻消能設計之實用性。" "The project is to upgrade low-frequency acoustic energy dissipation for multi-storey type of sandwich structures. These materials contain calcium silicate boards, fiber cement board, gypsum board partition, and other common building materials, with foam or porous rock sound-absorbing material. Construction materials are light compartment-effective, easy to assemble, and the advantages of shortening the construction period. By the low-frequency energy dissipation mechanism design, we can enhance the scope of building materials in the low-frequency acoustic noise reduction or sound-absorbing capacity. This study plans to use statistical energy law as well as porous materials theory, regarding this the multi-layered form light compartmented material, conducts the transmission loss performance research, eliminates the establishment multi-layer plate energy transfer weaken pattern, and by the actual experimental measurements and theoretical models each other than to confirm that the low-frequency energy dissipation design practicality."
