中文摘要 | 本研究之目的在於探討木質地板於不同結構之隔音及衝擊振動特性,與填加防振 材料後之改善效應,期使能應用於建築音響環境中,對提供良好之居住性。試驗時除比較不同 材種間之隔音性能外,並以紅櫟木製成之地板作為標準照板,比較各種木質結構地板的改善 程度,測試時應用音強法量測樓板衝擊音級,並對地板之衝擊振動特性加以分析,試驗結果 摘要如下:不同材種之地板材料,在樓板衝擊音級與振動加速度級之研判,呈現隨地板硬度 及彈性係數增大而有增加其隔音性能之趨勢。架高式地板在輕量衝擊源方面之改善效應大於 平舖直貼式地板,但對於重量衝擊音而言,則以平舖直貼式者為佳。填加吸音棉對樓板衝擊 及振動特性之共振皆有良好之改善效應。所有木質結構地板,於輕量衝擊源之樓板衝擊音級 改善效應,最佳者為填加杉拉巴+吸音棉,改善量為 9.9dB,即改善程度增加 13%;振動加 速級為杉拉巴 + 吸音棉 + 浮式角材 (B),改善量為 13.1dB,即改善程度增加 14%。 於重 量衝擊源之樓板衝擊音級改善效應最佳者,為填加杉拉巴+制振墊,改善量為 9.7dB,改善 程度增加 11%;振動加速度級之改善效應最佳者為杉拉巴+吸音棉+浮式角材 (B),改善量 為 11.1dB,改善程度增加 10%。 |
英文摘要 | The purpose of this study was to investigate the sound insulation performances of woody floors, and to understand the improvement effect by filling with other insulation materials or the different constructure types. This study would test the variation of different wood species, and as the contrast woody floors of red oak to compare with other kinds of woody floors. The sound intensity method was applied to the measurement of floor impact sound level(the sound intensity level and vibration acceleration level tested on woody floor). The important results are summarized as the followings:With respect to the woody floors, the floor which made from different wood species showed the higher hardness and MOE, this woody floor could increase the impact vibration characteristics. The floor made of the lumber frame type of the red oak floor panel showed the light-weight impact characeristics, it was better than the flat type. Filling with the glass fiber can improve the resonance of floor panel. All of the samples, the best improvement of sound intensity level (SIL) in light-weight impact was red oak panel which filling up the vibration-resistant pad with the glassfiber (9.9 dB) and the improved extent was 13%, the improved value was 13.1 dB and the improved extent was 14%. The highest improved effects on the SPL in heavey-weight impact was for red oak panel filling up the vibration-resistant pad with the vibration-resistant cushion (9.7 dB) and the improved extent was 11%. Regarding about the VAL, the panles filling up vibration-resistant lining with glassfiber and floating lumber (11.1 dB) and the improved extent was 10%, also it was the best. |
