中文摘要 | 國內建築對於樓版衝擊音級測定並不普遍,主因除了儀器設備外,測定法的複雜 ,使建築從業人員無法對施工中建築物樓版隔音性能進行檢核工作,本研究嘗試以實驗室小 試體樓版振動減低量預測現場衝擊音級減低量,以簡化工地現場更換表面材後樓版衝擊音測 定法,由理論計算及實驗測試結果得知,小試體樓版表面材振動減低量與現場樓版衝擊音減 低量之 1/1 Oct. 分頻相關性, 除 63 Hz R 值為 0.828 外, 其餘各頻率之 R 值均高達 0.97 以上,顯示以實驗室小試體表面材振動減低量(△ V ��)預測現場樓版衝擊音減低量 (△ V ��)是可行的。 |
英文摘要 | Impact sound level of floor or floor sound insulation is not routinly measured. The reason is not only due to the set-up of instruments, the complicated measureing method also intimidate the practice among domestic building constructors. This study attempts to test if vibration attenuation of small floor speciment tested in laboratory can predict field floor impact sound attenuation, the experiment may serve to simplify the complicated measuring method which tests the floor sound by changing surface materials in construction site. From our theoretical calculations and experimental results, there is a significant correlation between the vibration attenuation of small floor material specimen tested in laboratory and field floor impact sound attenuation. Except a R of 0.828 in the range of 63 Hz, all other correlations in the octave spectrum are higher than 0.97. The results show that it is feasible to predict the field floor impact sound attenation by adopting a vibration attenuation test of small surface material specimen in the laboratory. |
