近年來樓板緩衝材多以玻璃棉、橡膠墊或發泡類等工業化之產品為主，在製程或回收利用上亦須依賴大量能源之供應。因此，本研究在地球永續與循環經濟之課題下，以栓皮櫟（Quercus suber）樹種作為研究對象，利用木栓層（Cork layer）組織特性，開發木質有機緩衝材，並搭配複合木地板之面材進行樓板衝擊音隔音性能之探討。研究結果顯示，在栓皮櫟樹皮顆粒使用比例為30%時，衝擊音降低量預估值達22dB，較10%及20%之比例條件佳，且低頻衝擊音降低量數值較常見之橡膠發泡與PU發泡佳，顯示本研究之木質有機緩衝材除符合生態綠建材之原則外，亦可提升建築樓板之隔音性能。

In recent years, glass wool, rubber, and foam were the main materials used in floor resilient material, which consume a lot of energy in the process of recycling. Under the topic of earth sustainability and circular economy, in this study, we took Quercus suber as the research object, and use the organizational characteristics of the Cork layer to develop wood organic resilient material. We discussed the floor impact sound insulation performance of laminate wood flooring and wood organic resilient material. The result showed when using 30 % cork oak, the impact sound reduction value of the floor covering was 22 dB. The impact sound insulation performance of low frequencies of wood organic resilient material was better than rubber and foam. The wood-organic resilient material produced in this study was in line with ecological green building materials and improved the sound insulation performance of building floors.
