中文摘要 | 本文利用音響實驗室以牆板標準衝擊源衝擊三文治石膏板,量測衝擊音級,衝擊 方式為單擺方式,衝擊源包括軟性衝擊源及剛性衝擊源兩類。透過量測多片石膏板之衝擊 音,以實驗計劃法分析三文治石膏板構造材料組合中各因子對牆板衝擊音級之影響;結果 顯示,板材之貢獻率最大,即板材對於衝擊音級之大小有最明顯之影響;當板材為雙層石 膏板時,比較於單層石膏板,其衝擊音級可降低7.1dB及8.5dB。填玻璃棉則可降低約3.0dB。 |
英文摘要 | Adopting two standardized impact sources, such as a soft impact source and a hard impact source, impact sandwich gypsum panels when using an oscillatory method in the semi-anechoic room, then we measure levels of impact sound in a reverberation room. For the study on impact sound, there are several kinds of gypsum panel are tested. In order to analyze influence factors of impacts sound, It is evaluated by experimental design method. The results show that surface material gets the highest contribution. Comparing to one-layer gypsum panel, Two-layer gypsum panel can reduce 7.1dB to 8.5dB. And filling the glasswool into cavity of sandwich gypsum panel can reduce about 3.0dB. |
